BEFORE INSTALLING

This information is included as a quick reference installation guide. Refer to
the appropriate control panel installation manual for detailed system infor­mation. If the modules will be installed in an existing operational system,
inform the operator and local authority that the system will be temporarily
out of service. Disconnect power to the control panel before installing the
modules.

NOTICE: This manual should be left with the owner/user of this equipment.

GENERAL DESCRIPTION

The HFS-MR Relay Control Module is intended for use in intelligent, two­wire systems where the individual address of each module is selected using
the built-in rotary switches. It allows a compatible control panel to switch
discrete contacts by code command. The relay contains two isolated sets of
Form-C contacts, which operate as a DPDT switch and are rated in accordance
with the table in the manual. Circuit connections to the relay contacts are
not supervised by the module. The module also has a panel controlled LED
indicator.

COMPATIBILITY REQUIREMENTS

To ensure proper operation, this module shall be connected to listed-compat­ible control panels only.

MOUNTING

The HFS-MR mounts directly to 4-inch square electrical boxes (see Figure 2A).
The box must have a minimum depth of 21/8 inches. Surface mounted electri­cal boxes (SMB500) are available. The module can also mount to the HFS-D
or DNR(W) duct housing.

WIRING

NOTE: All wiring must conform to applicable local codes, ordinances, and reg­ulations. When using control modules in nonpower limited applications, the
CB500 Module Barrier must be used to meet UL requirements for the separa­tion of power-limited and nonpower-limited terminals and wiring. The barrier
must be inserted into a 4˝ × 4˝ × 21/8˝ junction box, and the control module
must be placed into the barrier and attached to the junction box (Figure 2A).
The power-limited wiring must be placed into the isolated quadrant of the
module barrier (Figure 2B).

1. Install module wiring in accordance with the job drawings and appropri­ate wiring diagrams.

2. Reference the control panel device address map to determine appropriate
addressing.

3. Set the address on the module per job drawings.

4. Secure module to electrical box (supplied by installer), see Figure 2A.

Wire should be stripped to the appropriate length (recommended strip length
is 1/4“ to 3/8”). Exposed conductor should be secured under the clamping plate
and should not protrude beyond the terminal block area. Caution: Do not loop
wire under terminals. Break wire run to provide supervision of connections.

WARNING

All relay switch contacts are shipped in the standby state (open) state, but may have transferred to the activated (closed) state during shipping. To ensure that
the switch contacts are in their correct state, modules must be made to communicate with the panel before connecting circuits controlled by the module.

IF ANY WIRING TO TERMINALS 4 – 10 IS NONPOWER
LIMITED, THE CB500 BARRIER IS REQUIRED. THE CB500
INCLUDES A NONPOWER LIMITED LABEL, WHICH MUST
BE PLACED OVER THE POWER LIMITED TERMINAL
INFORMATION ON THE NAMEPLATE LABEL.

MODULE DOES NOT SUPERVISE CONTROLLED CIRCUITS

*NOTE: ANY FAULT IN THE POWER SUPPLY IS LIMITED TO THAT ZONE AND DOES NOT RESULT IN A FAULT IN A SEPARATE ZONE.
