** Automatic door chime **
It is a simple yet effective device that sounds when someone passes the sensor .
Has a "3m" Extra strong sticking pad on the rear, or it could be mounted with a single screw or simply left standing on it's side.
This years model is very discreet measuing just 7 x 5 x 2 cm.
The Unit is powered by 2 "aaa" cell batteries (not included).
Simply switch it on and set it next to your door. It will sound "Ding DONG" when someone walks past it.
There is a high and low volume switch
The range is 4 metres and the sensor beam is quite narrow so that it should not annoy you go off if someone is close to it but to one side of it.
