The FLM‑325‑IM Contact Module provides a variety of fire
alarm functions, such as monitoring manual pull stations,
waterflow devices, or other dry contact fire alarm
activation applications. The module allows for alarm,
trouble, and supervisory conditions. The module is
mounted inside of a single‑gang back box and is normally
out of view.

System Overview

The FLM‑325‑IM Contact Module allows compatible fire
alarm control panels (FACP) to supervise Form A or B dry
contact devices in a polling circuit. The module has an
eight‑bit microprocessor and communicates with the
control panel (both power and data) over a two-wire
polling circuit. The initiating device circuit (NFPA Style B)
connected to the module can have up to 20 normally-open
(NO) dry contact devices. Each module can monitor one
normally-closed (NC) device (NC devices must be non­alarm applications).

Data Circuit Length

Data (or polling) circuit length is the distance over the
circuit wire from the connection at the FACP to the most
distant device and back to the FACP. Data circuit length
must include the distance to any device connected to the
circuit in a T tap. The screw terminals can accept up to 14
AWG (1.5 mm) wire, but this reduces the allowable length
of the circuit.

Refer to the FPE‑1000‑SLC Installation Guide
(P/N: F01U078099) for specific wire instructions and
specifications for the FPA‑1000 series panels.

Initiating Device Circuit Connections

The initiating device circuit can use any number of UL­listed normally open (NO) contact closure devices. Device
circuit wiring must not exceed 50 Ω. Install contact
closure devices according to the manufacturer’s
installation instructions. All wiring must be supervised and
power-limited.

Note Do not mix fire alarm initiating and

supervisory devices on the same module.
