Although fire detection is absolutely necessary, false alarms are a serious side effect of many fire alarm systems. The Fire Sentry line of flame detectors integrate with fire alarms for rapid, accurate and reliable detection of true fire emergencies. The detectors use a series of algorithms to speed the detection of a real fire event while eliminating false alarms. While monitoring for spikes in the radiant energy of a flame, the detector also monitors the entire flame spectrum for inconsistencies to unequivocally verify an alarm. It also measures both hydrocarbon and non-hydrocarbon gasses, eliminating the need for two devices.
