Modern Open Area Smoke Detectors

Smoke is the initial indication to a fire accident which might occur, if nothing is done to prevent it. The job of a smoke detector is to raise an alarm after detecting smoke in an area. Smoke detection is generally effective in enclosed areas like a room, a house or an office. But, smoke detection in open areas is quite an ordeal.

Need of Modern Open Area Smoke Detectors:

The situation becomes more complicated in open areas such as airports, malls, stadiums, etc. Sometimes traditional open area smoke detectors raise false fire alarms which hinder the work and also are not cost effective to raise smoke alarms in each and every corner of an open area space. These detectors help to eliminate the problems of traditional smoke detectors improve the safety aspect.

New Technology and Variety:

In modern times, various smoke detectors are being developed for open areas. These new technologies are – Very Early Warning Smoke Detectors (VESDA), open area smoke imaging detection (OSID) by XTRALIS, visual flame detection, and laser detection systems. These systems if applied to specific areas are helpful in preventing potential hazards in open areas, where the loss of life and property due to fire can be much higher.

Very Early Warning Smoke Detector (VESDA): VESDA is an aspirating smoke detector. It works on the light scattering principle. It captures air and examines it, if smoke is detected in the air sample, the VESDA raises a fire alarm. This system of detection prevents the smoke detector from raising false alarms.

Open Area Smoke Imaging Detection (OSID): The OSID system uses infrared and ultraviolet rays to examine the smoke levels in the environment. It implements the technology of imaging to analyze and measure the strength of the wavelength of the emitted infrared and ultraviolet rays. OSID filters the contamination in the air and then detects the smoke threat level. The OSID system works within an area of about 20,000 sq. ft. and is more cost effective than VESDA.

These new age smoke detectors detect smoke level in the atmosphere continuously, thus doing a pretty good job of preventing fires in open areas.
