FSI-851

The NOTIFIER FSI-851, made by Notifier for integration with Multicom ICS systems, is an analog, addressable, low-profile (height measures only 1.66"/42.164 mm) smoke detector designed for the entire line of intelligent systems from NOTIFIER.If either condition (smoke or heat) is detected, the device will alarm.

The addressability of the FSI=851 enables the control panel to provide firefighters with a pinpoint description of where the fire is located. The FSI-851is an analog device. The control panel is capable of not only knowing the detector's location but exactly how much smoke is in the chamber of the detector. The detector may be set for different sensitivity settings appropriate to the environment of its location.

Analog devices continually send obscuration values to the control panel. These values may be gathered so as to allow the control panel to determine if a detector has accumulated an excessive amount of dirt or dust. A "maintenance" required indication allows the installer to clean the smoke detector before an unwanted false alarm occurs.

The FSI-751 Intelligent Ionization Sensor incorporates a unique single-sound chamber designed to respond quickly and dependably to a broad range of fires.

The FSI-851 Intelligent Photoelectric Sensor's unique optical sensing chamber is designed with superior signal to noise ratio. The optical chamber is engineered to sense the presence of smoke produced by a wide range of combustion sources.

FlashScan® (patent pending) is a new communication protocol developed by NOTIFIER Engineering that greatly enhances the speed of communication between analog intelligent devices and certain NOTIFIER systems. Intelligent devices communicate in a grouped fashion. If one of the devices within 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.
