Capabilities
When installed with a MS-9600, the LDM Series modules can annunciate the
status of 99 software zones or 318 points (per SLC Loop) plus system status.
Each lamp driver output is assigned to one and only one system I/O point:
Addressable Devices -
Detectors - SD350, SD350T, CP350, H350, H350R, D350P & D350LP
Monitor Modules - MMF-300, MMF-301, MMF-302 & MDF-300
Control Modules - CMF-300
Addressable Pull Stations - BG-12LX
System Control Switches -
Acknowledge, Signal Silence, System Reset & Drill
Trouble Indication
Communication between the MS-9600 and the LDMs is accomplished over a
two-wire EIA-485 serial communication bus. The EIA-485 bus is supervised
by the MS-9600. Loss of communication results in system trouble message on
the panel's display.
Programming and Testing the LDM-32F
After complete installation, the Lamp Driver Module(s) must be programmed
into the control panel as if it were an annunciator. After programming the fire
alarm control panel to accept them, fully test the LDM(s) by ensuring that each
switch and LED performs its intended function, and that the LDM(s) can
perform the functions outlined in "3. Operation" on page 27.
Power and EIA-485 Connections
Regulated 24 VDC power and the EIA-485 communication circuit must be
connected to the MS-9600 as illustrated below.
Note: An external power source may be used to power the LDM Series.
