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.
