Notifier LDM-32 High-Speed Network Communications

Notifier LDM-32 High-Speed Network Communications Module

Lamp Driver Module with 32 alarm drivers; or 16 alarm, 16 trouble, and 16 switch inputs. One LDM-E32 is allowed per LDM-32 in alarm-only mode. Three LDM-E32 modules are allowed per LDM-32 in alarm/trouble. Includes ribbon cable to connect to ACM. 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.

LDM-32 High-Speed Network 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.
• 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.

The LDM Series lamp driver modules, when paired with a custom graphic display, offer annunciation and control for Fire Lite’s intelligent fire alarm control panels. These modules utilize a serial communications interface and can be installed up to 6,000 feet away from the panel.

The Lamp Driver Module Notifier LDM-32 features 32 alarm lamp/LED driver outputs that sink current to the system common (–) upon activation. It requires a single positive (+) voltage source to power all lamps or LEDs when all drivers are active. The LDM-32F includes a dedicated driver for system trouble indicators and inputs for a local lamp test switch. Additionally, it supports up to 16 external control switches.

DIP switch SW3 provides various configurations, including enabling or disabling the onboard piezo, activating remote switch functions, selecting a flashing LED option for new alarms and troubles, and other features. Switch SW4 allows the module to be set up for either 32 alarm annunciations or 16 trouble indications.

The Notifier LDM-32 module includes a green ON LINE LED that flashes to indicate active communication with the host fire alarm control panel (FACP). One LDM-32F module can support up to three LDM-E32F extension modules. The LDM-32F is supplied with four standoffs and screws, allowing for mounting on a CHS-4L chassis or a custom back box.

Product Line Information

Notifier LDM-32 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.
