In recognition that fires are serious events in performance spaces, and also that false alarms can be quite disruptive to a show, several manufacturers have developed sensors that employ multiple fire detection technologies. One of these stands-out above the rest and should be considered when upgrading your systems to meet the current fire safety codes (or to get rid of those pesky false alarms): It is the 2251-COPTIR Advanced Multi-Criteria Fire Detector manufactured by System Sensor (http://www.systemsensor.com/).
Having these sensing elements working in tandem is what sets the detector apart from any other technology available on the market. The confirmation and intelligent assessment capabilities will also prove to be ideal for places that are prone to nuisance alarms. Such sites include theaters and other entertainment venues that use special effect smoke.
“It allows us to provide the most accurate fire detection possible while providing superior nuisance rejection for those problem sites,” said Todd Alford, product manager. “Different fires have different characteristics, and each fire is a little bit different. By combining four elements, we can successfully filter out nuisance concerns and provide accurate fire detection.”
One side note: The detector's CO (Carbon Monoxide) sensor has a limited life span and must be replaced about every 5-6 years. The good news is that just because the CO detector ceases to function after that time, doesn't mean that the rest of the Multi-Function fire detector quits working - it just looses one of it's areas of sensitivity. A small price to pay for virtually no false alarms. Besides that, if you KNOW it must be replaced after a finite time, then you can PLAN FOR IT, and GET IT IN THE BUDGET and ONTO THE MAINTENANCE CALENDAR — what a concept — planning for an equipment failure — before it happens.
