Each AVTECH Sound, Light & Entry Sensor provides real-time recognition of sound, light and/or entry such as a door opening, closing, etc. With adjustable sensitivities, the Sound, Light & Entry Sensor is designed to be mounted on a vertical surface such as a wall or pillar in unmanned closets, telecom rooms, remote data rooms or other low traffic facilities.

This is an instant 'Plug & Play' sensor via one of the switch sensor channels on the back of any compatible Room Alert ID box. Cable distance can be extended from the standard 25' to approximately 900' by using standard speaker wire, twisted pair or any reliable low voltage 2-wire cable.
