The magnetic door contact unit sends a wireless signal to the chime when the door is opened and the chime will ring. The plugin chime (or chimes) can be positioned in the back office to alert someone's entry. In addition, the chime bell push button can be used as a disability option to gain attention. The chime unit can detect upto a maximum of 6 wireless signals (a mix of bell pushes, magnetic contacts and PIR's). If a lamp is plugged into the chime unit, this will flash 5 times when the door is opened or the bell push pressed.
