Notifier LDM-32 — lamp driver module that lights the lamps or LEDs of a custom graphic annunciator for Notifier intelligent fire alarm control panels.
A graphic annunciator is a site-specific mimic of a building with a lamp at each point; the LDM-32 is the electronics behind it.
- 32 alarm lamp-driver transistors, sinking to power common on alarm
- DIP switches reconfigure it as 16 alarm, 16 trouble and 16 switch inputs, the inputs driving panel Silence, Reset or remote relay control
- Two-wire EIA-485 loop and a two-wire 24 VDC power loop, up to 6,000 ft from the panel; up to 32 LDM systems per panel
- Integral piezo sounder on each new alarm or trouble, silenced by Local Acknowledge or disabled by DIP switch
- About 4.4 × 7.1 in.; four standoffs in the graphic box or a CHS-4L chassis; UL and ULC certified S635, FM approved
The LDM-E32 adds 32 more drivers and ships with its ribbon cable; the LDM-R32 converts the outputs to 32 Form A dry contacts at 1.0 A, 30 VDC. Notifier lists instructions as the only item supplied with the LDM-32, so the graphic cable is the separate LDM-CBL24 or LDM-CBL48.

FAQ
Are the lamp cables included?
No. Cable sets for the LDM-32 outputs are the optional LDM-CBL24 (24 in.) and LDM-CBL48 (48 in.); each cable supports eight output lamps.
How far can it be from the panel?
Up to 6,000 ft. It connects over a two-wire EIA-485 loop plus a two-wire regulated 24 VDC power loop.
How many LDM annunciators can one panel run?
Up to 32 LDM systems per control panel, each with a capacity of 64 points, for a total of 2,048 points.
How is it expanded?
The LDM-E32 expander adds 32 more drivers, and the LDM-R32 provides 32 dry-contact relays for electrical isolation.
