NOTIFIER FDRM-1 Dual Relay & Monitor Module – 2 Inputs, 2 Outputs, SLC, UL Listed

Description

The NOTIFIER FDRM-1 Dual Relay and Monitor Module is a versatile, intelligent solution that integrates two relay outputs and two Class B monitor inputs into a single compact unit—perfect for installations requiring advanced fire alarm system control with minimal hardware.

Designed for use in two-wire addressable loops, the FDRM-1 reduces installation time and material costs by combining the functionality of two individual control modules and two monitoring modules. Each relay supports Form C switching applications, ideal for control of door holders, fans, or notification appliances where supervision of the load circuit is not required. The monitor inputs interface with normally open contact-type devices like manual call points and tamper switches.

The module uses rotary decimal addressing for fast and intuitive configuration (addresses 1–159). Its intelligent design assigns up to four addresses, automatically allocating them to the outputs and inputs, while unused functions can be disabled via DIP switches, freeing up addresses for other devices on the loop.

Key Features:

• Combines 2 relay outputs and 2 Class B monitor inputs in one module
• Addressable-analog communication with rotary address switches
• Form C relay contacts for dry contact switching (non-supervised)
• Each output/input has its own LED indicator for easy status checks
• Compatible with NOTIFIER’s intelligent fire alarm panels
• Direct SLC loop power — no additional power source needed
• Compact, low-profile design for modern system layouts
• SEMS screws with clamping plates for secure wiring
• Wide operating temperature range: 32°F to 120°F (0°C to 49°C)
• UL listed for fire alarm system applications

Ideal for applications where space, efficiency, and flexible control are critical, the NOTIFIER FDRM-1 provides powerful control and monitoring in a single module—making it a top choice for professionals designing smart, scalable fire safety systems.
