Notifier FDM-1 Intelligent Dual Monitor Module

The Notifier FDM-1 Intelligent Dual Monitor Module provides reliable input monitoring for two separate Class B initiating device circuits (IDCs). Designed to integrate seamlessly with Notifier fire alarm control panels, the FDM-1 offers precise supervision and control of multiple contact devices while maintaining compact installation.

Dual Input Monitoring Made Efficient

Engineered for high-performance monitoring, the FDM-1 supports two independent dry-contact inputs. These can be configured to monitor pull stations, waterflow switches, or other contact-type devices. Each input operates independently and reports its status back to the fire alarm control panel using Notifier’s intelligent communication protocol.

This dual-input capability allows installers to reduce the number of modules required for complex systems, optimizing space and lowering material costs.

Key Features of the FDM-1 Module

• Dual Class B input circuits for supervising two dry-contact devices

• Intelligent addressability for system-wide integration and flexibility

• LED indicators for visual status confirmation and easier troubleshooting

• Compact design that fits into standard electrical boxes or enclosures

• Flexible mounting options, both surface and flush

• UL listed for compatibility with a wide range of fire safety systems

Easy Configuration and Integration

The Notifier FDM-1 features rotary decimal switches for fast and accurate addressing. Once connected, each input independently communicates with the panel, allowing clear identification of activation points. Moreover, the module’s compact profile ensures it fits conveniently into tight electrical spaces.

In addition, system designers can customize response behavior through control panel programming, enabling features like alarm verification, delay functions, or tailored annunciation.

Ideal Applications

This module is ideal for monitoring devices in fire alarm systems that require multiple inputs within a single module footprint. Common uses include:

• Manual pull station circuits

• Waterflow and tamper switches

• Beam detector relay contacts

• Mechanical system supervision

The Notifier FDM-1 Intelligent Dual Monitor Module is a space-saving, cost-effective solution for intelligent fire alarm systems. Its dual input design, simple configuration, and robust compatibility make it a go-to option for professional installers. Whether you’re expanding an existing system or designing from scratch, the FDM-1 enhances monitoring capabilities without adding complexity.
