The NC802DEB-1/2 is a button-operated call/reset point capable of generating Standard and Emergency calls on an 800 Series Call System.
It includes a 6.35mm jack plug socket where you can connect an optional tail call lead, pressure mat or other ancillary calling device.
When the red LED lights up this confirms a call has been made.
If the onboard reset button is pressed this cancels Standard and Emergency calls made from the NC802DEB-1/2 and Standard calls made from other devices wired on the same zone (such as ceiling pull units in En-suite areas).
Mounts on a standard UK 25mm single gang flush or surface back box.
