Fire Detection, Control Panels and System Accessories
The M500R Addressable Relay Control Module is an intelligent interface module designed to provide reliable switching of external equipment from compatible addressable fire alarm control panels. Featuring a DPDT relay with two isolated Form-C contact sets, the M500R enables safe and dependable control of auxiliary devices while maintaining the flexibility required for modern fire detection and life safety systems.
Operating on 15–32 VDC, the M500R is controlled directly by the fire alarm panel via the signalling line circuit (SLC), allowing remote activation of external circuits without requiring additional control wiring. The relay contacts support a range of AC and DC loads, making the module suitable for controlling equipment such as smoke control systems, door holders, dampers, fans, warning devices, plant shutdown circuits, and other life safety interfaces.
The module includes a panel-controlled LED indicator for clear visual status indication and is designed for installation in a standard 4-inch square electrical box or optional SMB500 surface mount box. For applications involving non-power-limited wiring, the optional CB500 barrier provides separation in accordance with installation requirements.
