The HFS-MR is an Intelligent relay module for use with Fire-Lite MS-25 (E) Fire Alarm Control Panel where the individual address of each module is selected using the built in rotary switches.

The Honeywell HFS(A) intelligent module products are designed to meet a wide range of applications.

Each module is rigorously designed and tested for electromagnetic compatibility and environmental reliability. Modules are addressed with easy-to-use rotary code switches.

The HFS-MR(A) Relay Module contains two isolated sets of Form C contacts, which operate as a double-pole, doublethrow switch. The module allows the control panel to switch these contacts on command. It mounts in a standard 4 in. x 4 in. x 21/8 in. junction box. Wiring terminals are easily accessible for troubleshooting.
