u Two independently configurable Form C contacts

u Contacts are rated 1 A at 30 VDC or 0.5 A

at 125 VAC

u Module address programming with the D5070

Analog Device Programmer

The modules provide two independently controlled
Form C contacts while utilizing only one address point
at the Signaling Line Circuit (SLC). The two Form C
contacts can be used for a variety of Normally Open
and Normally Closed applications such as fan, elevator
and door control, or auxiliary notification.
As the modules use mechanically latching relays, a
separate 24 VDC power supply is not required.
They fit into a standard 4‑inch square or double‑gang
electrical back box.

Functions

Flexibility

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

Status display

The modules have a green LED that flashes every time
the module is polled.

u Bi‑colored LED provides module status

u Digital data communications and power over a

two‑wire circuit

Short Circuit Isolation

The FLM‑325‑2R4‑2AI and FLM‑325‑2R4‑8AI modules
have built‑in short circuit isolating (SCI) circuitry. In
the event of a short circuit on the SLC line, the SCI
circuitry will prevent entire loop failure, 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.
