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

FCM-1 Supervised Control Modules are intended for use in intelligent, twowire systems, where the individual address of each module is selected using the built-in rotary switches. This module is used to switch an external power supply, which can be a DC power supply or an audio amplifier (up to 80 VRMS), to notification appliances. It also supervises the wiring to the connected loads and reports their status to the panel as NORMAL, OPEN, or SHORT CIRCUIT. The FCM-1 has two pairs of output termination points available for fault- tolerant wiring and a panel-controlled LED indicator. This module can be used to replace a CMX-2 module that has been configured for supervised wiring operation.

COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible Notifier system control panels only (list available from Notifier).

MOUNTING

The FCM-1 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 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. Set the address on the module per job drawings.
3. 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.
   IMPORTANT: When using the FCM-1 for audio applications, remove Jumper (J1) and discard. The Jumper is located on the back as shown in Figure 1B.
   J1 must be removed whenever power supply monitoring feature is not required.

NOTE: All references to power limited represent “Power Limited (Class 2)”.
All references to Class A also include Class X.

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

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.
