The MI-PSE-S2I Photoelectric smoke detector has an integrated isolator and delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from ingress of insect and other debris. The plug-in unit uses sophisticated processing circuitry that incorporates smoothing filters to help eliminate transient environmental noise conditions that can be the cause of unwanted alarms. The devices are managed by embedded software running complex algorithms that further improve resilience to false alarms and improve detection speed. The detectors have two integral tri-colour LED’s that provide 360o local visual indication of the device status. The LED’s are programmable with static or blinking red, amber and green status indicators available. All detectors are environmental friendly and meet the WEEE and RoHS legislative requirements, minimising end of life disposal cost, and are mechanically and electrically backwards compatible with existing devices. The detectors include the standard protocol as well as the new advanced protocol for enhanced communication with the future Morley-IAS panels, offering more features.
