FLM-325-NA4 Supervised Output Modules

The modules provide a supervised polarity reversal output used for audible and visual signaling devices or to trigger a remote NAC power expander. They require a 24 VDC auxiliary input voltage that can be provided by the FPA 1000 Analog Addressable Fire Panels or other UL listed power supplies.

The modules provide a Class B Circuit rated for 2 A at 24 VDC. They fit into a standard 4 inch square or double gang electrical back box.

Functions

Evacuation Tones

The following programmable patterns are selectable:

•Steady

•Pulsing

•Temporal 3

Flexibility

The operating parameters for the modules are saved at the integrated EEPROM and maintained by the module so that during emergency situations no communication with the fire panel is needed which provides flexibility and quick response to emergency conditions. The fire panel only broadcasts system conditions on the Signaling Line Circuit (SLC) and each module processes them according to its configuration.

uContacts are rated 2 A at 24 VDC

uFlexible application and quick response to emergency conditions

uCan be alarmed or reset by zone or by individual address

uModule address programming with the D5070 Analog Device Programmer

uBi colored LED provides module status

Status display

A bi colored LED flashes every time the module is polled and can be switched on steady when the module goes into active condition.

Short Circuit Isolation

Built in short circuit isolating (SCI) circuitry that, in the event of a short circuit on the SLC line, will prevent entire loop failure and send a short circuit condition report to the FACP, and, upon removal of the short circuit condition, automatically restore the entire loop to normal operation.
