LDM Series Instruction Manual — P/N 15885:H3 8/12/2019 11
Switches LDM Features
UL contact ratings are 0.5A at 125VAC (resistive) and 1.0A at 30VDC (resistive). Refer to UL Power Limiting Requirements for wiring
the Relays. The relays are programmable.
J11 - 5 VDC Power
This connector is located only on the LDM-32. 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-32 and three LDM-E32s (from J5, J6, J7, J8 and one system trouble LED)
provided
the current rating per LED is 2 mA.
2.5 Switches
SW1 and SW2 - Address Switches
Two rotary BCD switches, located only on the LDM-32, 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 config-
urations 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.
SW3 - Function DIP Switch SW3, which is located only on the LDM-32, is used to set the annunciator functions. Function settings
include:
• Number of expanders connected
• 8-Point Shift enabled
• Receive Only communications to host FACP (no system control switches or loss of supervision)
• Receive/Transmit communications to host FACP (system control switches plus supervision)
• Control Switch Disable
• Piezo disable
• Flash Inhibit
Refer to the appropriate appendix for your FACP for additional information.
SW4 - Alarm/Trouble Mode Switch The Alarm/Trouble mode switch is installed on the LDM-32 and LDM-E32. T he switch setting on
each expander module must match the switch setting of the associated LDM-32. ' 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.
2.6 Terminal Blocks
TB1 - Power, Earth Ground and Supervision Removable terminal block TB1 appears only on the LDM-32. 24 volts power-limited,
regulated, non-resettable power from the host FACP or a compatible UL listed battery backed power supply must be connected to TB1-3
(+) and TB1-5 (-). Terminals TB1-2 (+) and TB1-4 (-) may be used to daisy chain the 24 volts to other LDMs or devices. Earth ground
must be connected to TB1-1. Terminals TB1-6 and TB1-7 provide a supervised input which may be used to supervise local power
sources or other devices. A trouble signal is transmitted to the host FACP upon an open circuit across these terminals. The input must be
power-limited. If these terminals are not used, a jumper must be installed.
Note:
TB1: 24VDC nom, 27.6 VDC max, max current is 56mA
TB2: Maximum cable characteristic impedance is 120 ohms +/- 20%.
Limit wire resistance to 100 ohms.
TB2- In/Out Removable terminal block TB2 appears only on the LDM-32. All LDM-32s must connect to the EIA-485 communications
bus circuit for proper operation. The EIA-485 bus carries commands and data sent between the host FACP and the LDMs. The input
must be power-limited.
2.7 Cables
Expander Ribbon Cable (75120) The Expander Ribbon Cable is supplied with the LDM-E32 to allow for connection to the LDM-32
master module. The cable connects between J2 of the LDM-32 or LDM-E32 and J3 of the next LDM-E32.
The LDM-CBL24 and LDM-CBL48
Cable sets for connecting LDM-32 and LDM-E32 connectors to lamps/LEDs, switches, etc., are
provided through the optional LDM-CBL24 (24" long) and LDM-CBL48 (48" long) cabling kits. Each cable has a plug on one end for
connection to the LDM modules.
Each LDM-CBL24 cable kit includes:
• (4) P/N 75116, 24" cable consisting of 8 stranded, multicolored conductors. Cables connect to J5, J6, J7 and J8.
• (1) P/N 75122, 24" cable consisting of 10 stranded, multicolored conductors. Connects to J1, optional control switches.
• (1) P/N 75117, 24" cable consisting of 2 stranded, single color conductors. Connects to J1, Lamp Test Switch.
• (1) P/N 75118, 24" cable consisting of 3 stranded, multicolored conductors. Connects to J9 or J11, Lamp Power.
Each LDM-CBL48 cable kit includes:
• (4) P/N 75147, 48" cable consisting of 8 stranded, multicolored conductors. Cables connect to J5, J6, J7 and J8.
• (1) P/N 75150, 48" cable consisting of 10 stranded, multicolored conductors. Connects to J1, optional control switches.
• (1) P/N 75148, 48" cable consisting of 2 stranded, single color conductors. Connects to J1, Lamp Test Switch.
• (1) P/N 75149, 48" cable consisting of 3 stranded, multicolored conductors. Connects to J9 or J11, Lamp Power.
