u Monitors Normally Open (NO) or Normally

Closed (NC) contacts

u Monitored Normally Closed (NC) contacts can be

configured with or without EOL resistor

The FLM-325-I4-A and FLM-325-I4-AI modules are used
to connect standard Normally Open or
Normally Closed dry contact types of fire alarm
devices such as pull stations or water flow devices.
The modules are mounted to a cover plate for a
4‑inch square or double‑gang electrical back box. A
bi‑colored LED provides the module status.

Functions

Address Range

Contact Monitor modules must be programmed with a
unique address. All devices connected to module
appear only as one single address at the fire panel.
The modules are compatible with 254 addresses.

Status Conditions

The module supervises the wiring to the contact with
an EOL resistor. If a fault condition occurs, the module
sends a trouble signal to the fire panel.
If a status change occurs, the module sends an
interrupt signal to the fire panel indicating that an
alarm has occurred.

Data Circuit Length

Data (or polling) circuit length is the distance over the
circuit wire from the connection at the fire panel to
the most distant device and back to the fire panel.
Data circuit length must include the distance to any

device connected to the circuit in a T‑tap. The screw
terminals can accept 14 AWG (ISO 2.5 mm2) wire;
thinner wire can be used, but this reduces the
allowable length of the circuit.

Initiating Device Circuit Connections

The initiating device circuit can use any number of UL
listed 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.

Notice

Do not mix fire alarm initiating and supervisory
devices on the same module.
