The IQ611MR is an intelligent addressable relay module designed to extend the control capabilities of fire alarm systems. Providing two simultaneously activated relay output sets, it takes a single address on the Signaling Line Circuit (SLC) or Data Communication Link (DCL) of the fire alarm control panel — enabling precise, programmable control of auxiliary devices such as door holders, fans, lifts, and other building systems.

Clear Status Indication
A red LED provides continuous visual feedback on the module’s status. During normal operation it blinks every 4 seconds; when an event is activated, the LED blinks at an extended rate to indicate the active condition, returning to normal once the event clears.

Flexible Installation
Compatible with both Class A/DCLA and Class B/DCLB circuit configurations, the IQ611MR mounts directly onto a standard 2×4 or 4×4 electrical box using the IQ611B surface wall box. Wiring is straightforward with 12–18 AWG wire.
