BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the 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-MM minitature monitor module can be installed in a single gang
junction box directly behind the monitored unit. Its small size and light weight
allow it to be installed without rigid mounting (see Figure 1). The HFS-MM is
intended for use in intelligent, two-wire systems where the individual address
of each module is selected using rotary switches. It provides a two-wire initiating device circuit for normally open contact fire alarm and security devices.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to listed-compatible control panels only.
FIGURE 1:
MOUNTING AND WIRING
NOTE: This module is intended to be wired and mounted without rigid connections inside a standard electrical box. All wiring must conform to applicable local codes, ordinances and regulations.
1. Connect the red (+) and black (–) wires to the positive and negative loop
power leads of the signaling line circuit (SLC).
2. Connect the violet (+) and yellow (–) wires to a two-wire, normally open
initiating loop.
3. Install the specified EOL resistor value to terminate the initiating loop.
4. Reference the control panel device address map to determine appropriate
addressing.
5. Set the address on the module per job drawings.
6. Install the module in the desired mounting location.
