Description

Notifier FSI-851A Series intelligent plug-in smoke detectors with integral communication provide features that surpass conventional detectors. Besides, detector sensitivity comes programmed in the control panel software. Point ID capability allows each detector’s address to be set with rotary, decimal address switches, providing exact detector location for selective maintenance when chamber contamination reaches an unacceptable level. Also, the Notifier FSI-851A photoelectric detector’s unique optical sensing chamber comes engineered to sense smoke produced by a wide range of combustion sources. Dual electronic thermistors add 135°F (57°C) fixed temperature thermal sensing on the FSI-851T(A). Furthermore, FSI-851(A) series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).

In fact, FlashScan® is a communication protocol developed by Notifier that greatly increases the speed of communication between analog intelligent devices as well as intelligent devices communicate in a grouped fashion. Additionally, If one of the devices in the group has new information, the panel’s CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of earlier designs.
