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

u Bi‑colored LED provides module status

u Digital data communications and power over a

two‑wire circuit

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.

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.
