The LDM Series lamp driver modules, when combined with a
custom graphic display, provide annunciation and control for
Notifier’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.
Features
- 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.
Construction
Two basic models are available; the LDM-32 control module
and the LDM-E32 expander module. Each may be selected to
provide 32 alarm indications; or 16 alarm, 16 trouble, and 16
control points.
Applications
The LDM-32/LDM-E32 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-R32 module may be used to provide 32
dry-contact relays for electrical isolation when connecting the
system to other equipment.
Installation
The LDM-32 and LDM-E32 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 test-
ing.
Operation
LDM Series modules, when used with a custom graphic
annunciator, provide the Notifier’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.
AM2020/AFP1010 system alarm and/or trouble conditions
may be annunciated on a per-point basis, or in a grouped-zone
configuration.
AFP300/400 system panel points, intelligent addressable
devices and software zones can be annunciated/controlled in
a grouped fashion (see programming manual for details).
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-32: Lamp Driver Module with 32 alarm lamp-driver tran-
sistors (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.
