LDM-E32F
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-32Fs with LDM-E32F expanders
increase the system annunciation 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.
