Alarm Systems Definition (Global/KT-NCC) |
An alarm partition is a gathering of devices or equipment arranged to signal and detect the presence of an alarm condition requiring immediate attention or operator acknowledgement . The system offers up to 100 virtual alarm partitions per gateway. A virtual alarm partition is an alarm partition that is entirely controlled by the gateway instead of using a hardware device designed to perform the same function. Depending on how virtual alarm partitions are programmed, they can trigger various relays on alarms.
Example of an Alarm Partition
The system shall be able to partition the different areas of the building into up to 100 VASP (Virtual Alarm System Partition). Each VASP partition can be set up using any number of readers, door contacts, motion detectors, sirens and user access rights. Monitored points can be used in more than one partition.
Operation
Each area can be delimited by doors equipped with readers and monitored with door contacts. Single reader doors can also be equipped with a T.REX exit detector to provide hands-free door unlock. As required for the security of each area partitioned, the VASP will control a collection of the following devices: readers, door contacts, motion detectors, heating/air conditioning control, exit delay warning device and door locks.
Arming, Postponing and Disarming
Each VASP can be defined with an auto-arming schedule for each day of the week including holidays. At the programmed arming time, the exit delay warning will sound for a minimum of 4 minutes. Any employee in the area who is not allowed to stay later than the arming time will have to leave the area. At the end of the exit delay, the area will arm and will be monitored for intrusion and, possibly, for turning off or changing the settings of the air conditioning or heating system. During the exit delay, if an authorized employee wants to remain in the secured area later than the arming time, that employee can use his/her card at any of the readers of the area defined as a “postponement reader” in the system. This operation will initiate the postponement of the arming. The postponement delay can be pre-programmed for each area, up to eighteen hours and twelve minutes (18h12’). After the postponement period, the system will attempt to arm again and sound the exit delay. The same scenario of postponement will be available to employees wanting to remain in the area unless a maximum number of postponements (if programmed) or a “no disarm” scheduled time has been reached. Each card of the system can be programmed to allow or limit the use of this feature.
When an area is armed, it can be disarmed by authorized cardholders (who share the right to disarm the alarm partition) by presenting their cards at a disarming reader (as defined in the system). If the cardholder is authorized in that area during that specific time, the door will unlock and the partition will be disarmed as soon as the cardholder opens the door. If disarming happens at a time when the system would be normally armed by a schedule, the system will attempt to re-arm automatically after the postponement time described earlier. In addition to those tasks performed by cardholders, an authorized operator (such as a guard) can manually operate the partitions from any of the system's workstations (disarm, arm or modify the postpone delay time).
Alarm System Capabilities
• Up to 100 different independent alarm partitions can be programmed per gateway.
• Each alarm partition can supervise any input or door of the system.
• When defining alarm partitions, elements such as: doors, readers, input zones and output relays can be defined as single or group.
• Each alarm partition can include inputs or doors supervised by one or more alarm partitions as shared elements (common).
Note: If a same input is defined for 2 alarm partitions, and only one system is armed, if this input generates an “alarm”, it will not be reported. Both alarm partitions must be armed for the input to report the alarm condition.
Common Inputs
Input zones or doors, which are shared by multiple alarm partitions, are related according to the following rules:
• An alarm partition will only produce an alarm from an input / door common to other alarm partitions if all the alarm partitions containing that input / door are armed. Inputs or doors which are part of “Alarm Level 1 and 2” can be defined in a different way but have to be part of a group.
• Alarm level 1 and 2 (input groups) are processed together as one large group for the purpose of determining whether an input (zone) is also included in another alarm partition definition.
• Common doors which are defined as “Door to be locked on arming” or “Door disabled on arming” in both alarm partitions will revert to their normal state if one or more of these alarm partitions is disarmed.
Perimeter and Volumetric Detection
The devices of an alarm system are grouped in two categories, perimeter and volumetric detection.
Perimeter (Alarm Level Inputs)
Perimeter detection refers to the detection of access to the outer limits of a detection area by means of physical barriers such as: door contacts, glass break detectors, door contacts on uncontrolled doors, etc.
Usually, inputs that are defined as “perimeter” (glass breaks, garage doors, fire doors, door with door contacts not controlled, etc.) are grouped and defined as “alarm level #1 inputs”. When one of these inputs are activated, it will activate the “alarm relay #1” relay which can be connected to an “alarm panel” that will send a warning to the central indicating a parametric intrusion. A perimeter detection is considered more important since it originates from the perimeter of the controlled area. For supervised doors (reader, T.REX, door contact), you can use the field Supervised door when armed to group the doors that will also activate the “alarm relay #1” when a “door forced open” or “door open too long” event is generated for these doors. For example, main entrance doors or back entrance doors can be included in this field.
Volumetric (Alarm Level # 2 Inputs)
Volumetric detection refers to detection of access of the volume, such as an entire room or part of a room by means of volume detectors such as: movement detectors or sensors, controlled doors (readers, etc.). Inputs defined as “volumetric” (PIRs, sensors (heat), etc.) are grouped and defined as “alarm level # 2 inputs”. When one of those inputs is activated, it will activate the “alarm relay #2” relay which can be connected to an “alarm panel” that will send a warning to the central indicating a volumetric intrusion.
Arming Procedure
There are three (3) methods to arm an alarm system:
1 - Manual arming: This is done at the Manual operation window at the workstation by an authorized operator. The alarm system will be armed once the exit delay is over.
2 - Automatic arming (arming schedule): The alarm partition will initiate the exit delay when the arming schedule becomes valid. The alarm partition will be armed once the exit delay is over.
3 - Arming at a door reader (with or without an arming request button): There are 3 possible choices:
• With a card—The card is presented at the reader defined as “arming reader”. The exit delay is initiated, once over the alarm partition will be armed.
• With a card and an “arming request input”—The card is presented at the reader defined as “arming reader”. The “arming” delay is initiated. The “arm request input (button)” must be pushed during this delay to confirm arming. Once the arming request input is pushed, the exit delay is initiated and the alarm partition will be armed once the exit delay is over.
• With only an “arming request input”—The “arm request input (button)” must be pushed to confirm arming. Once the arming request input is pushed, the exit delay is initiated and the alarm partition will be armed once the exit delay is over. To only use an “arming request input”, no reader must be defined as “arming reader”.
Note: Arming is done by presenting a card at the door reader (or entering a number on the keypad) defined as “arming reader” in the alarm system definition menu. Arming at a door reader is only permitted by a card with the defined arming access level, which must include access to the arming reader in question.
Disarming Procedure
This command disarms the alarm system. Depending on how the partition is programmed, results can be different.
• Manual disarming: This is done at the manual operation window at the workstation console by an authorized operator. The alarm partition will disarm right away, unless a “no disarm” schedule is valid, this command will initiate the “postpone” delay.
• Disarming at a door reader using a card: Disarming is done at the door reader (or keypad) defined as “disarming reader” in the system.
General Rules:
• Disarming is done by presenting a card at the door reader (or entering a number on the keypad) defined as “disarming reader” in the alarm system definition menu.
• Manual disarming is only permitted by a card with the defined disarming access level, which must include access to the disarming reader in question.
• If there is a door contact defined for the door, then the door must be opened for disarming to take effect. If there is no contact, you don't have to open the door.
• If the arming reader is also defined as “disarming reader”, the door will have to be open to disarm the system. On the other hand, if a “no disarm” schedule is effective, a disarming request will postpone the arming of the system.
Disarming when “No Disarm” Schedule is Valid Procedure
If a “no disarm” schedule is in effect and a user disarms the system, the system will be in the “postpone delay” mode, when this delay expires, the system will be in the “exit delay” mode, when this delay expires, the system will arm again automatically, if the schedule is still valid at that time. In this case the limit on the number of postponement delays is effective only after the initial delay. Arming an alarm partition can be postponed for a pre-set period (maximum 16.5 hours) after which the system will automatically arm only if the “no disarm” schedule is valid at that time.
Postponing Arming Procedure
A postponement arming can be activated in two ways, depending on the circumstances:
1 - During the exit delay (when the system is being armed, whether armed manually or by arming schedule).
2 - While the system is armed, during any interval when the “no disarm” schedule is valid, the normal disarming of the system will automatically initiate a postponed arming, for a number of times not exceeding the maximum number defined in the postpone count field.
Notes:
• In either cases, the system will automatically arm itself at the end of the postponement delay (when the postponement delay expires, the exit delay is initiated) only if the “no disarm” schedule is in effect at the time.
• A postponed arming can only be activated at door readers defined as “arming reader” or as “postponing reader”.
• For a door reader defined as “postponing reader”, you can only postpone during the “exit delay”.
• For a door reader defined as “disarming reader”, you can postpone during the “exit delay” or when the system is armed and a “no disarm” schedule is valid.
• A postponed arming can only be activated with a card with the “disarming access level”, which has to include access to the door from which it is to be activated.
• A postponed arming can be activated during the “exit delay” when the system is being armed, during a postponement delay already in progress or when the system is armed and a “no disarm” schedule is valid.
• If a postponement-arming request is done when one is already in progress will reset the postponement delay and decrement the count of consecutive postponement allowed, if the limit has not already been reached. A limit is defined (0-15) for the number of successive postponement delays permitted.
Warning: An entry of 0 in the “postpone count field” will cause an infinite number of successive postponements to be permitted.
• Should a reader be defined as BOTH the arming and disarming reader for a given alarm partition, its function with respect to postponement will be as the postponement reader, i.e. postponement will initiate immediately upon card access.
To Define an Alarm Partition
1 - Click the Alarm System button.
2 - From the Select gateway window, select a gateway associated with the alarm partition.
3 - From the Alarm System drop-down list, select an existing alarm system or click New to create a new alarm system
4 - From the Arming Schedule field, select a schedule according to which the alarm partition will automatically arm at the time that this schedule becomes valid (the exit delay will be initiated before the system actually arms). This schedule is used only to arm the system, do not insert the “All valid” schedule. When this schedule becomes invalid, the system will not disarm, it will remain armed until presentation of a valid card at a disarming reader. You can right-click the selection field to create a custom arming schedule.
5 - From the No Disarm Schedule field, select a schedule during which a disarming attempt will initiate postponing of the alarm partition. Once the postpone delay is over, the system will automatically initiate the exit delay and arm automatically once expired.
6 - Select the Access and delays tab to define access level options:
• Arming Access Level: select the access level required to arm the alarm partition. Arming the system requires the arming access level and access to the arming reader(s).
• Disarming Access Level: select the required access level to disarm the alarm partition. Disarming the system requires the disarming access level and access to the disarming reader(s).
7 - In the Delays (hh:mm:ss) section, specify the entry and exit delays:
• Entry: specify the entry delay time during which a user will have access to a supervised area to disarm the system.
• Exit: Enter the exit delay. The exit delay is used to warn employees that the system will be armed once this delay is expired following an arming request. The system can be in the “exit delay” mode following:
• An arming request,
• or when the “postpone delay” is expired and the “no disarm” schedule is still valid.
• Arming: Enter the arming delay time. This is the delay allowed by the system between the moment that a card is presented at an arming reader and the moment that the “arming request button” is pushed to confirm arming.
• Postpone parameters: Enter the postpone delay time. The postpone delay is a “period” during which the alarm partition is disarmed.
• If the “no disarm” schedule is still valid, the system will enter in “exit delay” then arm again when the exit delay expires.
• If a postpone or disarming operation is attempted during this “exit delay” the system will return to the postpone delay.
• If the “no disarm” schedule is NOT valid, the system will automatically disarm at the end of the postpone delay.
• The postpone delay can be manually modified through the manual operations section of the system.
Note: It is possible to associate a relay that will be triggered when an arming, disarming or postpone delay is initiated. It could for example provide a visual feedback on a status panel to indicate that the system is waiting for a confirmation.
• Postpone Count: This option specifies the maximum number of times the alarm system can be postponed. When the maximum count is reached, the system will initiate the exit delay and arm automatically (if a “no disarm “schedule is still valid) or disarm if a normal arming schedule is valid.
Note: If set to “0”, the alarm partition can be postponed indefinitely.
8 - Select the Door tab to define the arming and disarming, and postpone options:
• Arming reader: Select a door or door group that will be used to arm the alarm partition. Arming will only work at an arming reader. Arming the system requires the arming access level and access to the arming reader(s).
Note: Usually, arming readers are located near exit doors.
Note: If more than one alarm partition can be armed with the same arming reader, use an “arming request input” to confirm arming.
• Disarming reader: Select a door or door group that will be used to disarm the alarm partition. Disarming will only work at a disarming reader. Disarming the system requires the disarming access level and access to the disarming reader(s).
Note: Usually, disarming readers are located within the perimeter of the protected area. For example, a disarming reader could be located at the front door where a video surveillance camera is located for visual recording.
• Arming reader no unlock: Select a door or door group that will be used to arm the system without unlocking the door.
• Postpone reader: Select a door or door group that will be used to postpone the alarm partition from arming. Postponing arming requires the disarming access level and access to the postpone reader. A postpone reader can only be used during the “exit delay”.
Note: Usually, postpone readers are located within the protected area so as to allow employees to postpone the system from any reader located inside.
• Reader disabled when armed: Select a door or door group for which the readers are disabled when the alarm partition is armed. No access is permitted, even for cards with the required disarming access level and at the disarming reader.
Note: For example, this field can be used to select a back door in order for users to use the front door to disarm the system.
• Door to be lock on arming: Select a door or door group that will be locked when the alarm partition is armed. It will override the unlocking schedule (even if valid) and will also override a manual unlocking operation.
• Supervised door when armed: Select a door or a group of doors that will generate an alarm level # 1 (perimeter) and trigger the relay selected in the Alarm # 1 Relay State field (Relay 2 of 2 tab) if the events “door forced open” or “door open too long” are produced by these doors while the system is armed.
9 - Select the Input tab to define input for arming and disarming:
• Alarm level #1: Select a single input or a group of inputs that will automatically activate the relay selected in the Alarm # 1 Relay State field (Relay 2 of 2 tab) if the system is armed and an alarm is detected from one of the selected inputs.
• Alarm level #2: Select a single input or a group of inputs that will automatically activate the relay selected in the Alarm # 2 Relay State field (Relay 2 of 2 tab) if the system is armed and an alarm is detected from one of the selected inputs.
• Arming request: Select a single input or a group of inputs that must be “in alarm” to confirm arming of the alarm partition. An arming request input should be used when more than one alarm partition can be armed with the same arming reader. Usually, a button is used as an arming request input. The card is presented at the reader, the “arming delay” is initiated, the button is pushed, the exit delay is initiated after which the alarm partition will arm.
10 - It is possible to associate a relay that will be triggered when the arming delay is initiated. It could for example provide a visual feedback on a status panel to indicate that the system is waiting for a confirmation.
• Prevent arming: Select a single input or a group of inputs. If any of these inputs is “in alarm” when arming is attempted, arming will not succeed and will be aborted. Usually inputs from “Alarm Level 1 & 2” are grouped together as one group and selected. This will group all the inputs of the alarm partition. This is only true when an arming request is done at a door reader with an arming request input.
Note: If the alarm partition is armed automatically with an “arming schedule”, the inputs will be ignored and arming will succeed.
Note: It is possible to associate a relay that will be triggered when the arming is aborted.
• Input for entry delay: Select a single input or a group of inputs used to initiate the entry delay. If any of these inputs is “in alarm” when the system is armed, the entry delay will be initiated and inputs selected in the “Shunted on Disarming” field will be shunted for the duration of the “entry delay”.
• Shunted on disarming: Select a single input or a group of inputs that will be shunted (not monitored) when the “Entry Input” is triggered. These inputs will be shunted for the duration of the entry delay.
11 - Select the Control Relay tab to define the relays that will be used to indicate or display various status for the alarm system being defined. For each relay, it is possible to determine when the relay will return to its normal condition. There are 2 possible conditions:
• Temporary: The relay will remain temporarily activated for the activation time programmed in the relay definition menu. Be careful, if the relay activation time is set to zero in the relay definition menu, the relay will “follow” the condition or device condition even if it is programmed to be temporarily activated.
• Follow: The relay will remain activated until the condition that triggered the relay is over.
Note: When a relay is activated or deactivated from of an alarm system, EVENTS WILL NOT be generated.
• System Armed—Relay: This relay will be triggered when the alarm partition is armed.
• System Disarmed—Relay: This relay will be triggered when the alarm partition is disarmed.
• System Status Relay: This relay will reflect the status of the inputs of “Alarm Level #1 and #2” as well as doors of the “Door supervised when armed” field.
• Prevent arming Relay State: Select the relay that will be triggered when the arming sequence is aborted due to an input in alarm generated during arming. Select, from the pull-down menu, the relay activation.
12 - Select the Status Relay tab to define the relays that will reflect the various conditions of the alarm system being defined.
Note: When a relay is activated or deactivated from an alarm system, EVENTS WILL NOT Postpone Relay—Select the relay that will be triggered when the alarm partition is in “postpone” mode.
• Entry Relay State: Select the relay that will be triggered when the “entry delay” is initiated.
• Exit Relay State: Select the relay that will be triggered when the “exit delay” is initiated.
• Arming Delay State: Select the relay that will be triggered when the “arming delay” is initiated.
• Alarm #1 Relay State: Select a relay that will be triggered when the alarm partition detects a valid alarm condition (i.e. input in alarm) from one or more inputs defined in the “Alarm Level #1” field or from one or more doors (i.e. door forced open or door open too long) defined in the Supervised door when armed field.
• Alarm #2 Relay State: Select a relay that will be triggered when the alarm partition detects a valid alarm condition (i.e. input in alarm) from one or more inputs defined in the Alarm Level #2 field.
• Bell-Relay state: Select a relay that will be triggered when the alarm partition detects a valid alarm condition (i.e. input in alarm) from one or more inputs defined in the Alarm Level #1 field or from one or more doors (i.e. door forced open or door open too long) defined in the Supervised door when armed field. Usually an audible signal is initiated with this relay.
Linked Partitions
Alarm integration, for global gateway and KT-NCC, allows linking existing virtual alarm systems in EntraPass to DSC partitions and Honeywell groups.
Once the panel is created on a gateway, a new Linked Partition tab is displayed in the virtual alarm systems menu.
Up to 8 partitions or groups can be linked to a virtual alarm system. The following tasks can then be performed:
• Arm
• Arm no delay (if supported)
• Disarm
• Arm and Disarm
• Arm no delay and Disarm
Note: If a partition belongs to more than one virtual alarm system, all these systems will have to be armed first for the partition to be armed.
