Fire detector IP 212-142 represents optical electronic device generating signals in case of smoke formation in the place of installation. Stand-alone smoke fire detector is based on microcontroller. Computer-aided processing of measuring results helps in making a decision on "Fire" signal generation and considerable reduce the likelihood of false alarm.

Depending on the state, fire detector activates various indicators:

  Alarming mode    Indication
     Light Sound   
     Standby Mode      Single flash with a repeat period of (5 ± 1) s

     -

     "Fire" mode      Blinking with frequency of (2 ± 0.2) Hz      Constant tone-modulated audible signal
     "Battery discharge" mode
 (at voltage of 7-5.9V)
 
-
     Short-term single audible signal with repeat period of 60 s


The detector shall be installed on a ceiling. Installation on walls, beams, columns, ropes at distance from 100 to 300 mm away from ceiling and at least 100 mm away from wall corners, taking into account the detector overall dimensions, is allowed.

Area to be monitored by one detector, distance between detectors as well as between a detector and a wall shall be as per the Table:

 Detector installation height, m  
 Area monitored by one detector, m  
     

 Maximum distance, m

 between detectors  detector-to-wall
     Up to 3,5      Up to 85      9.0      4.5
     Over 3.5 to 6.0      Up to 70      8.5      4.0
     Over 6.0 to 10.0      Up to 65      8.0      4.0
     Over 10.0 to 12.0      Up to 55      7.5      3.5


Detector provides the following:
  • due to computer-aided results processing, decision on "Fire" signal generation may be made with maximum precision and considerably decreased likelihood for false alarm;
  • optimal overall dimensions (Ø93 х 50 mm) and modern housing design;
  • wide range of operation temperature from minus 10°С to plus 55°С;
  • detector power supply is realized through power unit Krona (within the scope of supply) of nominal voltage of 9V.
Detector IP212-142 is least-cost option and may be used at social objects. Due to advanced technology, detector IP212-142 housing is made of recycled plastic. It contributes to detector cost reduction with quality preserving.
