System Sensor MS-KA/R Remote Accessory Duct Smoke Detector

Product Description

The SYSTEM SENSOR MS-KA/R is a remote accessory designed to extend the functionality of compatible duct smoke detectors. It provides a red alarm LED for visual indication of alarm status and includes a key-operated test and reset function. The unit is built from brushed stainless steel, giving it durability in commercial and light industrial environments. Licensed fire alarm technicians and HVAC professionals install this device as part of a complete duct smoke detection system, typically in air handling units and HVAC ductwork where code-required remote annunciation and manual reset capability are needed.

The MS-KA/R mounts on a standard single-gang electrical backbox, making it straightforward to integrate into existing electrical rough-in. It is intended for use in commercial HVAC applications where NFPA 72 and NFPA 90A compliance requires remote alarm indication and manual reset access at a convenient location away from the duct-mounted detector head. This is particularly common in large air handling unit installations where the primary detector is inaccessible during normal building operation.
