Designed for use in shops, to alert staff to the entry of anyone walking through the door. The system consists of a send/receive unit that transmits an IR beam across the doorway onto a reflector mounted on the opposite side. The beam is reflected back to the receiver to complete the circuit. When a person walks through the beam, the circuit is interrupted, and this causes the buzzer to go off. The warning buzzer can be mounted up to 10 metres away. Mains plugpack and mounting hardware are included.

You can also have an additional buzzer to put out in the back, but it still needs to be within 10 metres of the transmitter.

The volume of the buzzer is adjustable, and the sound output can be selected by a slide switch to either alarm, off, or chime. The sounding time can also be adjusted from 3 to 30 seconds.
Supplied with mounting hardware, a 10-metre lead, and an adjustment screwdriver.
