Patent abstract
Multiple parameter fire detection uses outputs from one or more radiant energy sensors in combination with outputs from smoke or thermal sensors to shorten response times to alarm while minimizing nuisance alarms. The radiant energy related outputs can be used to alter parameters of the smoke or thermal sensors. The various sensors can be displaced from one another in an alarm system.
