Honeywell Morley-IAS HM Series detectors incorporate modern hardware and software technology driven developments. An advanced optical chamber design is proven in extensive testing to be more efficient, less
liable to false alarm from dust and insects and less susceptible to fault in high air velocities or back pressure.

Extensive hydrodynamic modelling has confirmed the greater efficiency of the chamber and housing shape combination. Large-scale integration of the electronics, through the fully automated surface mount PCB
assembly, coupled with in-line testing through the manufacturing process, laser PCB cutting along with a completely new compound of plastic offers improved quality and reliability.

All detectors are environmentally friendly and meet the WEEE and RoHS legislative requirements, minimising end of life disposal costs.

Product Range
The family consists of four detection devices: two heat detectors (58° and a rate of rise), an optical smoke, and a photo-thermal multi-sensor. The detector base makes the installation process easy and quick.
These sensors are designed for open area protection and must only be connected to fire alarm panels that use a compatible proprietary communication protocol for monitoring and control (DXc panels R7, 8, 9).

Specifications: Optical Smoke Detector
The photoelectric smoke sensor delivers high responsiveness, reduced sensitivity to dust and 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 HM/PSE optical smoke detector has two integral red LEDs that provide 360° local visual indication of the device status.
