Introduction
The Notifier FRM-1 Control Relay Module is designed for use with intelligent addressable fire alarm control panels. It provides a Form-C dry contact relay for controlling external devices such as door holders, fans, dampers, or other auxiliary equipment. The module receives commands from the fire alarm control panel to activate or deactivate the relay, allowing for flexible system integration and control.
This manual provides essential information for the proper installation, operation, and maintenance of the FRM-1 Control Relay Module.
Product Overview
Figure 1: Front view of the Notifier FRM-1 Control Relay Module, showing the main components, wiring terminals, and mounting bracket. This module is designed for integration into fire alarm systems.
The FRM-1 module features screw terminals for easy connection to the Signaling Line Circuit (SLC) and the controlled device. It is designed for panel mounting and includes a robust housing for durability. The module's compact size allows for versatile installation within various enclosures.
Setup and Installation
Proper installation is crucial for the reliable operation of the FRM-1 module. Always refer to local codes and the National Fire Alarm and Signaling Code (NFPA 72) for specific installation requirements.
Pre-Installation Checklist:
- Ensure power to the fire alarm control panel is disconnected before installation.
- Verify the module's compatibility with your specific fire alarm control panel model.
- Have appropriate tools: screwdriver, wire strippers, multimeter.
- Confirm availability of suitable mounting space and wiring pathways.
Mounting:
The FRM-1 module is designed for panel mounting. Secure the module using appropriate fasteners to a stable surface within the control panel enclosure or a standard 4-inch square electrical box.
Wiring Instructions:
Connect the module to the fire alarm control panel's Signaling Line Circuit (SLC) and the external device according to the wiring diagram provided in your control panel's manual and the FRM-1 installation sheet. The module features screw terminals for secure connections.
- SLC (+) T1: Connect to the positive terminal of the SLC.
- SLC (-) T2: Connect to the negative terminal of the SLC.
- T9 N.C. 2, T10 COMM 2: Normally Closed contacts for relay 2.
- T7 COMM 1, T8 N.O. 2: Normally Open contacts for relay 2.
- T5 N.O. 1, T6 N.C. 1: Contacts for relay 1 (ensure correct usage based on system design).
Ensure all connections are tight and properly insulated. Incorrect wiring can lead to system malfunctions or damage.
Operating Principles
The Notifier FRM-1 operates as an addressable control module. Each module is assigned a unique address on the SLC loop during system programming. When the fire alarm control panel sends a command to this specific address, the internal relay within the FRM-1 module activates or deactivates, changing the state of its Form-C contacts.
This allows the control panel to remotely switch on or off external devices connected to the module, such as audible/visual notification appliances, smoke control dampers, or magnetic door holders, in response to alarm conditions or programmed events.
Addressing:
The module's address is set via rotary switches or similar mechanisms on the device itself. This address must correspond to the address programmed in the fire alarm control panel for proper communication and control.

Maintenance
The Notifier FRM-1 Control Relay Module is designed for long-term reliability with minimal maintenance. However, periodic inspection is recommended as part of your overall fire alarm system maintenance schedule.
Routine Checks:
- Visual Inspection: Annually inspect the module for any signs of physical damage, corrosion, or loose connections.
- Functionality Test: As part of the fire alarm system's annual testing, verify that the FRM-1 module activates and deactivates its connected device correctly when commanded by the control panel.
- Wiring Integrity: Periodically check all wiring connections to ensure they remain secure and free from damage.
Any maintenance or testing should be performed by qualified personnel in accordance with applicable codes and standards.
Troubleshooting
If the Notifier FRM-1 module is not functioning as expected, consider the following common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not responding to commands. | Incorrect address setting. SLC wiring issue. Module failure. | Verify the module's address matches the control panel programming. Check SLC wiring for opens, shorts, or incorrect connections. Replace the module if other troubleshooting steps fail. |
| Connected device not activating/deactivating. | Incorrect relay wiring. Faulty connected device. Relay contacts damaged. | Review the wiring diagram for the connected device and relay contacts. Test the connected device independently. If relay contacts are suspected, replace the module. |
| Module reports a fault on the control panel. | SLC wiring fault (open/short). Module internal fault. | Inspect SLC wiring for damage. Use a multimeter to check continuity. If wiring is confirmed good, the module may be faulty and require replacement. |
For complex issues or if troubleshooting steps do not resolve the problem, contact a qualified fire alarm technician or Notifier technical support.
