IP 212-142 fire detector 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:


Indication

Alarming mode

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.

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 50 mm) and modern housing design;
  • wide range of operation temperature from minus 10 to plus 55;
  • detector power supply is realized through Krona power component  (within the scope of supply) of 9V nominal voltage.

IP212-142 detector 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.
