The LDM Series Lamp Driver Modules, when combined with a custom graphic display, provide annunciation and control for the Sensiscan 2000, MS-9200, MS-9200UD, MS-9600 and MS-5210UD fire alarm control panels. These modules use a serial communications interface, and may be located up to 6,000 feet from the panel. • 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 notification 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 cost. • May be powered by 24 VDC from the panel or by remote power supplies. • Efficient switched-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. 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.
