HONEYWELL FS7-2173-2RP Detectors

HONEYWELL FS7-2173-2RP Detectors

DESCRIPTION

The Fire Sentry FS7-2173 electro-optical radiant energy fire detector and the Fire Sentry FS7-2173-2RP (unitised model) with multi-spectral WideBand IR™, Near Band IR and Visible Band fire detection are designed specifically for semiconductor clean room fire protection applications. The FS-2173-2RP is standalone and FS-2173 interfaces to a control module.

FEATURES

• Multi-Spectral digital electro-optical radiant energy infrared fire detector 

• Unique two-stage fire detection response 

• Immune to false alarm sources 

• NOT affected by absorbing smoke, gasses or chemical vapors 

• NOT sensitive to background radiant energy from electric heaters and ovens 

• Detects hydrocarbon and non-hydrocarbon fires 

• Rugged leak-proof, heat-sealed, acid-resistant, injection-molded polypropylene housing 

• Wide 120° field of view 

• Digital communication with RS-485 interface 

• FirePic™; time and date-stamped digital fire signatures 

• Built-in detector automatic self test 

• Unitised model design for stand-alone operation

Applications include: 

• Open areas of clean room 

• Wet bench working surface 

• Wet bench subsurface (Plenum) 

• Pumps and equipment located behind the wet bench area 

• Under-floor areas 

• IPA stations (unitised model only)

Advantages

High sensitivity: the detector is capable of detecting tiny flames and works effectively even in the presence of smoke or dust.

Highly resistant to interference: the detector is resistant to interference from sunlight, welding and other light sources to avoid false alarms.

Fast response time: able to detect flames and sound an alarm within seconds, helping to take timely countermeasures.

Easy to install and maintain: Compact size, easy to install and low maintenance cost.

Intelligent bi-polar response: with two-level response mechanism of warning and alarm, it warns against heat exceeding 3KW and allows time for the fire to extinguish itself; if the fire does not extinguish itself and exceeds the factory-set prevalence value of 13KW, it will activate the alarm.
