Morley-IAS – HM-PSE-I Photoelectric Addressable Smoke Detectors For Fire Alarm System
The HM-PSE-I Photoelectric Smoke Detectors smoke detector has a completely new detection chamber design, the result of many years of research and development. This delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from insect ingress 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 MI-PSE-S2 has two integral tri-colour LEDs that provide 360° local visual indication of the device status. The LEDs are programmable with static or blinking red, amber and green status indications available.
