The image shows a TRX/PEAK Infra-Red Motion Detector, specifically the IR Model No. EPIC 91 with Serial No. 6415. This is a type of Passive Infrared (PIR) sensor, commonly used in security alarms and automatic lighting applications.
Key features and applications:
Motion Detection:
It detects human movement by sensing infrared radiation emitted by the human body.
Wireless Operation:
As a wireless transmitter, it's designed to conserve battery life with an Automatic Power Saver (APS) circuit.
Installation Considerations:
Optimal performance is achieved when mounted to detect movement across its beams, and away from large metal objects, direct sunlight, or areas with rapid temperature changes.
Applications:
Widely used in security systems, motion-activated lighting in areas like corridors, bathrooms, basements, and garages.
