Multi-criteria fire detector
The 22051TE / 22051TEI multi-criteria fire sensor incorporates an opticalsmoke-sensing chamber and thermal-sensing elements combined with microprocessor control and sophisticated processing to eliminate transient noise conditions there by giving reliable fire detection whilst minimising unwanted alarms. It can respond either as a smoke detector, or a rate-of-rise heat detector or, using special algorithms combining both elements to provide improved reliability of detection.
The 22051TE / 22051TEI is an environmentally friendly replacement for an ionisation detector, providing rapid detection of fast, flaming fires without incurring the significant endof-life disposal costs associated with products containing radioactive material.
The 22051TE / 22051TEI is approved to a number of sensitivity settings: Three Photo-Thermal and two Auto-Adjusting, which slowly adjust the detector’s sensitivity to match short term changes in its environment, thus reducing the potential for nuisance alarms. In addition, it is possible to detect an alarm from heat only, for day/night operation for example.
22051TE / 22051TEI includes algorithms, which compensate for a slow build up of contamination, such as dust, within its optical sensing chamber. Once thedetector has reached its maximum compensation level, asignal can be sent to the control panel to indicate a the need for maintenance.
