The Bed Exit Mat Interface lets you add a bed mat to any call point that already has a call pendant, without installing another Call Button.
It plugs straight into the Call Button's 6.35mm pendant socket. One side has a pendant socket for a call pendant, and the bottom has an RJ12 socket for bed mats and other sensors. A matching Floor Mat Interface is also available, with a second pendant socket for floor mats.
A switch on the front turns off the second connection when it isn't needed, so there's no need for dummy plugs to prevent false alarms.
