Marketplace Product

DEA7WL2 is a compact wireless entry alarm system which is easy to install in both indoor and outdoor. It is designed for both residential and commercial using such as garage door, shops, warehouse restaurants and farm etc. to alert you to the entry of customers and visitors. The system consists of a send/receive unit which transmits an IR beam across the doorway onto a prismatic reflector mounted on theopposite side. The beam is reflected back to the receiver tocomplete the circuit. When a person walks through the beam, the circuit is interrupted and this causes the alarm to sound an audible warning. The warning buzzer can be mounted in any suitable location.
