Fire-Lite LDM-32F Lamp Drivers - Manual (Page 13)

Features 1. Introduction
LDM-32F PN 50055:C 03/20/01

J11 - 5 VDC Lamp Power
This connector is located only on the LDM-32F. J11 pin 1 provides 5 volts
regulated power to all lamps/LEDs used in a custom graphic annunciator. The
maximum current available from this output is 300 mA. This current is
sufficient to power the maximum number of LEDs available with one LDM-
32F and three LDM-E32Fs (from J5, J6, J7, J8 and one system trouble LED)
provided the current rating per LED is 2 mA.
Switches
SW1 and SW2 - Address Switches
Two rotary BCD switches, located only on the LDM-32F, are used to set the
LDM Series system address. Switch SW1 represents the ‘ones’ position and
switch SW2 represents the ‘tens’ position of the address setting. In system
configurations of 56 zones or less, the switches must be set to address 01 for
all LDMs in the system. For configurations larger than 56 zones, multiple sets
of LDMs are required with sequential addresses, the first LDM starting at
address 01. Each incremental setting adds 64 zones/points to the system.
For example, an MS-9200 system requiring annunciation of alarms and
troubles for all 198 points would require four sets of LDMs with addresses 01,
02, 03 and 04. The MS-9600 is an exception (refer to "Appendix C: MS-9600"
on page 51 for information).
SW3 - Function DIP Switch
SW3, which is located only on the LDM-32F, is used to set the annunciator
functions. Function settings include:
• Number of expanders connected
• 8-Point Shift enabled
• Receive Only communications to host FACP
• Receive/Transmit communications to host FACP
• Control Switch disable
• Piezo disable
• Flash Inhibit
Refer to "Function DIP Switch - SW3" on page 25 for additional information.
SW4 - Alarm/Trouble Mode Switch
The Alarm/Trouble mode switch is installed on the LDM-32F and LDM-E32F.
The switch setting on each expander module must match the switch setting of
the associated LDM-32F. ‘Alarm Only’ mode causes the driver outputs to turn
on only for alarm conditions per associated zone or point at the host FACP.
‘Alarm/Trouble’ mode causes the driver outputs to turn on for both alarm and
trouble conditions per associated zone or point at the host FACP. Since this
switch affects the assignments of connectors J5, J6, J7 and J8, make certain to
review the appendices in this manual for additional information on wiring to
the lamp/LED drivers.
