FireLite LDMR32 Lamp Driver Module


Our Price : $590.00

Product Code: LDMR32


The LDM Series lamp driver modules, when combined with a custom graphic display, provide annunciation and control for FireLite's intelligent fire alarm control panels. These modules use a serial communications interface, and may be located up to 6,000 feet from the panel.


Two basic models are available; the LDM-32F control module and the LDM-E32F expander module. Each may be selected to provide 32 alarm indications; or 16 alarm, 16 trouble, and 16 control points.


The LDM-32F/LDM-E32F with a custom graphic array may be used to indicate point status and, in some versions, to control the state of output points. In addition, the LDM-R32F module may be used to provide 32 dry-contact relays for electrical isolation when connecting the system to other equipment.


The LDM-32F and LDM-E32F modules mount on four standoffs inside the custom annunciator graphic box. Alternately, the modules may be installed in a CHS-4L chassis. The module size is approximately 4.4" (11.2cm) x 7.1" (18cm).

Communications between the LDM Series annunciators and the host FIre Alarm Control Panel are made through a two-wire EIA-485 multi-drop loop, and a two-wire regulated 24 VDC power loop. Up to 32 LDM systems may be connected to a single control panel. All field-wiring terminations use removable, compression-type terminal blocks for ease of installation, wiring, and circuit testing.


LDM Series modules, when used with a custom graphic annunciator, provide the Fire Lite's intelligent fire alarm control panels with up to 32 unique or redundant annunciators, each with a capacity of 64 points for a total capacity of 2048 points. Local or remote power supplies and serial communications allow the custom annunciators to be located anywhere on the protected premises.

Control of system operational controls, such as Signal Silence, System Reset, and local annunciation controls (such as Local Acknowledge), and Lamp Test may be accomplished through special key- or push-switches.

Product Line Information:

LDM-32F: Lamp Driver Module with 32 alarm lamp-driver transistors (sink to power common on alarm). May be selected (dip switch) for 16 alarm/circuit on, 16 trouble, and 16 switch inputs if desired. Also includes system-trouble lamp driver and lamp-test/local-acknowledge switch input. Integral piezo sounder sounds for each new alarm or trouble and is silenced with the Local Acknowledge switch, or permanently disabled with a dip switch selection. Flash of new alarms or troubles is selectable through dip switches. 16 switch inputs may be used for panel SILENCE, RESET, or remote relay control. Instructions are included.

LDM-E32F: Lamp Driver Module with 32 alarm drivers; or 16 alarm, 16 trouble, and 16 switch inputs. One LDM-E32F is allowed per LDM-32F in alarm-only mode. Three LDM-E32F modules are allowed per LDM-32F in alarm/trouble. Includes ribbon cable to connect to LDM-32F/LDM-E32F.

LDM-R32: Lamp Driver Module which connects to any LDM-32F or LDM-E32F to convert transistor outputs to 32 Form-A dry contacts (1.0 A @ 30 VDC). Provides 32 output terminal screw connections and a single common terminal screw. Includes ribbon cables to connect to the LDM-32F/LDM-E32F. Use for electrical isolation when interfacing the system to other equipment.

LDM-CBL24, LDM-CBL48: Ribbon cable sets to provide either a 24" (60.96cm) or 48" (121.96cm) connection between LDM-32F/LDM-E32F and LEDs or lamps on a custom graphic
panel. Includes all cables necessary for one LDM-32F or LDM-E32F. Cables have connector on one end only (split, strip, and connect other end to graphic annunciator).
  • ALARM/CIRCUIT ON and TROUBLE lamp/LED per-point option, or more dense alarm-only option (field selectable).
  • Control switch option for remote control per point.
  • Lamps/LEDs may be programmed to display status of indicating circuits or control relays as well as system status conditions.
  • System trouble lamp/LED signal.
  • On-line/power LED indicator.
  • Alarm and trouble resound with flash of new conditions.
  • Local sounder for both alarm/circuit-on and trouble conditions with silence/acknowledge switch connection.
  • Serial EIA-485 interface for reduced installation costs.
  • May be powered by 24 VDC from the panel or by remote power supplies.
  • Efficient switch-power converter reduces power consumption.
  • Microprocessor-controlled electronics, fully supervised.
  • Plug-in terminal blocks for ease of installation and service.
  • Trouble monitor option for remote power supplies.
