4.9 Zone Mimic Indicator Card ( Externally Powered. ) BRD25GIB -C
The externally powered Zone Mimic Indicator Card operates in the same way as does the
internally powered version. The only difference is that the 27 volt power supply is independent of
the FACP. This card would be used when the distance involved causes a significant voltage drop
such that it may effect the reliable operation of the system or the costs involved in the cable is
offset by the availability of a remote 27 volt supply.
Quiescent Current: 13mA ( This current applies to both cards )

The LAM provides remote stand alone FACP status, Alarm and Fault / Isolate Indication of 8
zones. Two push buttons, Lamp Test and Silence Buzzer, provide for local testing of the
indicators and buzzer while the buzzer duplicates that at the FACP. A maximum of 4 LAMs with
addresses of 1 to 4 may be cabled to an FACP.
