Information About M300RJ
The M300RJ is an addressable control module used with compatible Johnson Controls intelligent fire alarm control panels. Its two isolated Form-C contacts operate together as a DPDT switching arrangement and are controlled by commands from the fire alarm panel. Built-in rotary switches provide module addressing, while a panel-controlled LED indicates communication and activation status. The module operates from a 15–32 VDC signaling loop and mounts directly to a standard 4-inch square electrical box.
Key Features:
- Addressable Relay Module: Provides intelligent relay control on compatible two-wire fire alarm systems.
- Dual Form-C Contacts: Includes two isolated Form-C contact sets operating together as a DPDT switch.
- Dry-Contact Output: Provides relay contacts for switching connected auxiliary control equipment.
- Rotary Addressing: Uses built-in rotary switches for assigning the module address.
- Panel-Controlled LED: Provides visual indication of communication and relay activation status.
- Auxiliary Equipment Control: Suitable for controlling fans, dampers, and other external equipment.
- Direct Mounting: Mounts directly to a standard 4-inch square electrical box.
- Wide Voltage Range: Operates from a 15–32 VDC signaling loop.
The M300RJ delivers the reliability and precision required for intelligent fire alarm relay control and auxiliary equipment interface applications.
