Lamp/LED Driver Operation
LDM Address Switches (SW1 & SW2) must be set to address ‘01’.
Lamp Driver outputs do not latch - they track or follow the status of each zone/
point that they are assigned to annunciate. The table below defines the ON
status of each lamp driver output.
Note: Control Switches marked 'Not Used' will still function as local LAMP TEST or local
ACKNOWLEDGE switches for their respective points.
Note: If Alarm Only mode is selected, column labeled Yellow LED is not applicable and
control switches do not function.

1. If the 8-Point Shift (DIP switch #4 of SW3) is set ON, the eight Sensiscan 2000 CPU
functions (ACK, SIL, RESET, LAMP TEST, NAC1, NAC2, MUNTIE, RELAY) will be
shifted from annunciator points 1 through 8 (as shown above) to points 57 through 64
(provided those points exist in the system and the LDM-32F is set to address 01).
