Notifier FDRM-1 Dual Relay and Monitor Module User Manual

1. Introduction

The Notifier FDRM-1 is a dual relay and monitor module designed for integration into compatible fire alarm control panels. This module provides two independent Form-C relay contacts and two independent initiating device circuits (IDCs) for monitoring various devices. It allows for flexible control and monitoring within a fire safety system, enabling the activation of auxiliary functions and the supervision of external equipment.

2. Setup and Installation

Proper installation is critical for the reliable operation of the FDRM-1 module. Ensure all local codes and standards, as well as NFPA 72, are followed during installation. Disconnect all power from the control panel before beginning installation.

2.1 Mounting

The FDRM-1 module is designed for surface mounting. Use appropriate fasteners through the designated mounting holes on the module's bracket. Ensure the mounting surface is stable and secure.

This image displays the front of the module, highlighting the screw terminals for wiring connections, two rotary switches for address setting, and mounting tabs on the sides for secure installation. The labels for the dual monitoring and dual relay sections are visible.

2.2 Wiring

Connect wiring to the screw terminals as indicated on the module and in the system's design documentation. The module features terminals for two independent relay outputs and two independent monitoring inputs.

• Relay Outputs (Relay 1 & Relay 2): Each relay provides Normally Open (N.O.), Normally Closed (N.C.), and Common (COM) contacts. Connect external devices requiring activation (e.g., door holders, fan shutdowns) to these terminals.
• Monitoring Inputs (Monitor 1 & Monitor 2): These inputs are typically used to monitor the status of external devices (e.g., water flow switches, tamper switches). Connect the field wiring for these devices to the designated input terminals.
• Communication Loop: Connect the module to the fire alarm control panel's signaling line circuit (SLC) or equivalent communication loop terminals.
• Power Supply: Ensure proper power connections as per system requirements. The module may draw power from the SLC or require a separate supervised power supply.

Refer to the specific wiring diagrams provided with your fire alarm control panel and the FDRM-1 module for detailed connection instructions.

2.3 Addressing

The FDRM-1 module requires a unique address for communication with the fire alarm control panel. Set the module's address using the two rotary switches located on the front of the module. Consult your control panel's documentation for available address ranges and proper addressing procedures.

3. Operating Principles

Once properly installed and addressed, the FDRM-1 module operates under the control of the fire alarm control panel. It continuously monitors its two input circuits for changes in status (e.g., open, short, alarm condition) and reports these to the panel. Upon receiving commands from the control panel, the module can activate its two independent relays, changing the state of their N.O. and N.C. contacts to control connected auxiliary equipment.

The module's operation mode is automatic, responding to programmed events and conditions within the fire alarm system.

4. Maintenance

Regular maintenance ensures the continued reliability of the FDRM-1 module and the overall fire alarm system. Maintenance should be performed by qualified personnel only.

• Visual Inspection: Periodically inspect the module for any signs of physical damage, loose connections, or environmental degradation.
• Functional Testing: As part of the fire alarm system's scheduled testing, verify the proper operation of both monitoring inputs and relay outputs. This includes simulating alarm conditions for monitored devices and verifying relay activation.
• Cleaning: If necessary, gently clean the module's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.

5. Troubleshooting

If the FDRM-1 module is not functioning as expected, consider the following troubleshooting steps. Always consult the fire alarm control panel's manual for specific diagnostic procedures.

• Module Not Responding:
  • Verify correct addressing using the rotary switches.
  • Check communication loop wiring for opens, shorts, or incorrect connections.
  • Ensure the module is compatible with the control panel.
• Monitoring Input Fault:
  • Inspect wiring to the monitored device for opens or shorts.
  • Verify the monitored device is functioning correctly.
  • Check for proper end-of-line resistor (EOLR) installation if required.
• Relay Not Activating:
  • Confirm the control panel is sending the activation command.
  • Check wiring from the relay contacts to the controlled device.
  • Verify the controlled device is operational and its power supply is active.

If issues persist, contact qualified fire alarm system technicians or Notifier technical support.
