FCM-1 Supervised Control Module

ration of power-limited and nonpower-limited terminals and wiring. The bar-

rier must be inserted into a 4˝ × 4˝ × 2

/8˝ junction box, and the control

module must be placed into the barrier and attached to the junction box. (See

Figure 2A.) The power-limited wiring must be placed into the isolated quad-

rant of the module barrier. (See Figure 2B.)

1. Install module wiring in accordance with the job drawings and appropri-

ate 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

/4˝ to

/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 su-

pervision 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.

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 opera-

tor and local authority that the system will be temporarily out of service. Dis-

connect 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, two-

wire systems, where the individual address of each module is selected us-

ing 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 2

/8 inches. Surface mounted electri-

cal boxes (SMB500 Series) 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 sepa-

The FCM-1 Supervised Control Module is a device designed for use in intelligent, two-wire fire alarm systems. Its primary function is to switch an external power supply, such as a DC power supply or an audio amplifier (up to 80 VRMS), to notification appliances. The module also supervises the wiring to the connected loads, reporting their status (NORMAL, OPEN, or SHORT CIRCUIT) to the control panel.

Function Description:

The FCM-1 module acts as an interface between the fire alarm control panel's signaling line circuit (SLC) and external notification appliance circuits (NACs) or audio circuits. It allows the control panel to activate these external circuits for alarms, while also monitoring their integrity. Each module has a unique address, selected using built-in rotary switches, enabling individual control and status reporting. The module features two pairs of output termination points, supporting fault-tolerant wiring, and includes a panel-controlled LED indicator for visual status. It can replace a CMX-2 module configured for supervised wiring operation.

Usage Features:

Compatibility: The module must be connected to compatible Notifier system control panels. A list of compatible panels is available from Notifier.
Addressing: The individual address of each module is set using built-in rotary switches, allowing for precise control and identification within the system.
Wiring Supervision: The FCM-1 supervises the wiring to connected loads, reporting NORMAL, OPEN, or SHORT CIRCUIT conditions to the panel. This ensures the integrity of the notification circuits.
Fault-Tolerant Wiring: The module supports fault-tolerant wiring configurations (e.g., NFPA Class A) to maintain system operation even if a single fault occurs in the wiring.
Audio Applications: When used for audio applications (e.g., with 70.7 Vrms max audio amplifiers), Jumper J1 on the back of the module must be removed. This jumper is also removed if power supply monitoring is not required.
Power-Limited and Nonpower-Limited Applications: When used 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.
Speaker Supervision: The module supports supervision and switching for speaker circuits, ensuring that audio notification appliances are functional. Audio circuit wiring should be twisted pair.
Synchronization Modules: The module can be wired to MDL3R Series Sync Modules for synchronized notification appliance operation.

Maintenance Features:

Installation Guide: The manual serves as a quick reference installation guide. For detailed system information, users should refer to the control panel installation manual.
Temporary Out of Service Notification: Before installing modules in an existing operational system, operators and local authorities must be informed that the system will be temporarily out of service. Power to the control panel must be disconnected before installation.
Wiring Standards: All wiring must conform to applicable local codes, ordinances, and regulations. Wires should be stripped to the appropriate length (1/4" to 3/8"), with exposed conductors secured under the clamping plate without protruding beyond the terminal block area. Wires should not be looped under terminals; wire runs should be broken to provide supervision of connections.
Relay Contact State: All relay switch contacts are shipped in the standby (open) state but may have transferred to the activated (closed) state during shipping. To ensure correct contact state, modules must communicate with the panel before connecting circuits controlled by the module.
Module Barrier: The CB500 Module Barrier, when required, must be inserted into a 4" x 4" x 2 1/8" junction box, and the control module placed into the barrier. Power-limited wiring must be placed into the isolated quadrant of the module barrier.
Mounting: The FCM-1 mounts directly to 4-inch square electrical boxes with a minimum depth of 2 1/8 inches. Surface-mounted electrical boxes (SMB500 Series) are available, and the module can also mount to the DNR(W) duct housing.
