The 72051EI high sensitivity, high gain amplifier based intelligent smoke sensor is a unique offering from System Sensor that provides extremely high sensitivity to fire conditions, by detecting the earliest particles of combustion. It is an addressable plug-in type smoke detector suitable for extremely high sensitivity applications. These sensors are designed for open area protection and must only be connected to control panels (CIE) that use a compatible proprietary communication protocol for monitoring and control.

The detector runs a drift compensation algorithm to determine the level of dust contamination, and will give an indication to the CIE of the drift level. This smoke sensor contains an isolator. When installing the device using the isolator, check the panel documentation for details of how many isolators can be used on a loop The 72051EI is designed to be backward compatible with the 7251.

Features & Benefits:
