The LDM Series Lamp Driver Modules, which consist of the LDM-32F master and LDM-E32F expander modules, are
used to provide an interface to a custom graphic LED annunciator. The master module provides power and control for
a maximum of three expander modules. The LDM-32F and LDM-E32F have output connectors which are used to
drive lamps or LEDs and input connectors which are used for remote switch functions. Refer to the LDM Series Lamp
Driver Modules Manual for a complete description.

The Lamp Driver Module LDM-32F has 32 alarm lamp/LED driver outputs which sink current
to system common (-) on activation. A single positive (+) voltage is required to supply total
operating power for all lamps or LEDs when all drivers are activated. The LDM-32F pro-
vides a separate driver for system trouble and inputs for a local lamp test switch. A maxi-
mum of 16 external control switches may be wired to the LDM-32F. DIP switch SW3 is used
to enable or disable the onboard piezo, enable remote switch functions, select a flashing
LED function for new alarms and troubles, and other functions. Switch SW4 is used to
configure the module to annunciate 32 alarms or 16 alarms and 16 troubles. A green ON-
LINE LED flashes to indicate ongoing communications with the host FACP. One LDM-32F
supports up to 3 LDM-E32F modules. The LDM-32F is supplied with 4 standoffs and screws
for mounting to a CHS-4L chassis or custom backbox.

Each LDM-E32F expander module provides 32 additional lamp/LED driver outputs from J5,
J6, J7 and J8. The expander module has a slide switch, SW4, for selecting alarm or alarm
and trouble annunciation and an input for a local lamp test switch. In alarm mode, use only
one LDM-32F and one LDM-E32F for a maximum of 56 alarm indicators and 8 system status
indicators. In alarm/trouble mode, use one LDM-32F and three LDM-E32Fs for a maximum of
56 alarm indicators, 56 trouble indicators, 16 status indicators and 64 optional control switch
inputs. Multiple sets of LDM-32s with LDM-E32F expanders increase the system annuncia-
tion capabilities beyond 56 zones or points. This is possible by various settings of address
switches SW1 and SW2 on the LDM-32F (refer to Appendices). Each LDM-E32F is supplied
with a 26-conductor expander ribbon cable, 4 standoffs and 4 screws.
