Edwards RS-485-M

The Edwards RS-485-M is a network interface module for Edwards Signaling Millennium-class fire alarm control panels, enabling multi-panel communication and integration with remote monitoring stations over a two-wire serial network. This printed circuit board kit implements the RS-485 serial protocol standard, allowing multiple Millennium panels to share alarm and trouble information across Class A (Style 7) or Class B (Style 4) wired configurations. The module supports central station connection for off-premise monitoring and alarm transmission, providing network-scale system supervision for multi-building fire alarm installations and complex facilities requiring coordinated fire detection across distributed zones.
