Honeywell FS7 Multi-Spectrum Fire and Flame Detector

Product Overview

The Fire Sentry FS7 is a multispectral digital photoelectric radiation infrared fire and flame detector designed specifically for semiconductor cleanroom fire protection applications. It includes the FS7-2173 photoelectric radiation fire detector and the FS7-2173-2RP (modular model), the latter of which features multispectral WideBand IR ™、 Near band IR and visible light band fire detection function. Among them, FS-2173-2RP is independent, and FS-2173 is connected to the control module for use.

Core Features

Multispectral detection: using multispectral digital photoelectric radiation infrared technology, covering visible light, near band IR, and wideband IR detection ranges.

Two level fire detection response: Provide intelligent two-level response for semiconductor wet table fires. Level 1 (Alert): Respond to small fires with a heat output of 3kW (equivalent to a 100mm diameter polypropylene pool fire) and allow time for the fire to self extinguish; Second level (Alarm): If the fire does not self extinguish and expands to the 13kW thermal energy threshold specified by Factory Mutual (equivalent to a 200mm diameter polypropylene pool fire), the second level response is activated.

Anti interference capability: not affected by false alarm sources, not affected by absorbent smoke, gas or chemical vapor, insensitive to background radiation energy of electric heaters and ovens, capable of detecting hydrocarbon and non hydrocarbon fires.

Durable design: Adopting a sturdy leak proof, heat sealed, acid resistant injection molded polypropylene shell, with a wide field of view (120 °) and RS-485 interface for digital communication, FirePic ™  The function can record digital fire characteristics with time and date stamps, and the built-in detector has automatic self checking function. The modular model design can operate independently.

Application scenarios

Clean room open area

Wet table working surface

Wet platform underground space (ventilation room)

Pumps and equipment behind the wet table area

IPA station (only for modular models)

Product model details

FS7-2173

It needs to be used in conjunction with the Fire Sentry FS7-130-SX controller or FSWB control panel. The controller and control panel provide power to the detectors, monitor the status of all detectors, and communicate with the detectors through a digital RS-485 communication channel.

Standard 6m (20ft) cable connector, connected to the controller or control panel through self-locking connector and Fire Sentry junction box, easy to install and reduces wiring problems.

Each detector can store up to 6 FirePics with time and date stamps in non-volatile memory ™ (Pre event multispectral sensor array data), the controller and control panel can also store event history tables in non-volatile memory, including warning, alarm, and fault history with time and date stamps. FirePics can be retrieved from the controller or control panel ™  And the history of events.

FS7-2173-2RP (modular model)

Equipped with discrete relay output, designed as an independent detector that can interface with any approved fire alarm panel.

The microprocessor is equipped with digital signal processing algorithms to continuously monitor the circuit, and the sensors have built-in self checks to verify normal operation.

Requires an external 24VDC power supply, comes with a standard 6m (20ft) tail cable, and can store up to 6 FirePics with time and date stamps in non-volatile memory ™  With 200 events, FirePics can be retrieved using the Fire Sentry FS7 interface suite and Windows based PC software ™  And the history of events.
