silence/acknowledge, alarm silence and menu access for partial system control. The lamp test operation
is also enabled by the keyswitch and is limited to the annunciator. The annunciator mounts to a
horizontally mounted 6-gang box, 2” deep minimum. The FS-RD-SB/-R Surface Backbox may be used for
surface mounting. The FS-RD-SB is black and the FS-RD-SB-R is red.
