L622AN310 Call Point with Extended Inputs & Outputs.
The L622AN310 is a modification of the standard L622 unit with additional terminals to provide an emergency call
generation for WC or en-suit bathroom ceiling pull switches and L2/X3 terminals for SRP connection. (As per L722)
Operation of the unit is identical to the L622 Standard Unit. It can generate up to 6 independent levels of call which are
indicated by the integral twin colour re-assurance LED. There is a ‘call follower’ sounder which sounds when the call
point is in ‘staff present’ mode to inform staff of another call. The jack socket will accept any closing contact input
from pear leads, pressure mats, radio triggers and a host of other triggering devices. The X and L terminals are used to
connect to ceiling pull switches. Options which must be specified when ordering include; magnetic key reset,
