Potter Electric Signal ms-ra Remote Duct Alarm Accessory

Product Description

The POTTER ELECTRIC SIGNAL ms-ra is a remote duct alarm accessory designed for use with MS Series duct smoke detector installations. It provides both audible and visual alarm indication through a red LED indicator, giving technicians and building personnel a clear local status signal away from the detector head itself. Constructed of brushed stainless steel, the ms-ra is built for durable, long-term service in commercial HVAC and fire-life-safety applications. Licensed fire alarm technicians and HVAC service professionals install this device as part of a complete duct smoke detection system.

The ms-ra is suited for commercial and light industrial installations where duct smoke detectors are required by fire code. It mounts on a standard single or double gang electrical backbox, making it straightforward to integrate into new construction or retrofit projects. The device provides remote alarm indication at a location accessible to building staff or fire alarm control panels without requiring direct access to the duct detector itself.
