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
