INSTALLATION INSTRUCTIONS AND WIRING FOR
CAT. NO. RDC-3 REMOTE LCD ANNUNCIATOR
The RDC-3 Remote LCD Annunciator is an optional accessory for the MPC-6000 Fire Alarm System
Control Unit. The RDC-3 provides a 4 x 20-character LCD display along with the system status LEDs that
display the event status of the system. The enable keyswitch allows system reset, trouble
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 Faraday 12411 Surface Backbox may be used
for surface mounting.
