General

The revolutionary OPAL range delivers a totally new detector platform incorporating an advanced digital protocol. The advanced protocol delivers more devices on the loop and gives greater control, configurability and device management whilst enabling the overall system to be optimised to the location and use of the building with far greater flexibility than ever before.

Opal incorporates major hardware and software technology driven developments. A completely new optical chamber design is proven in extensive testing to be more efficient, less liable to false alarm due to 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 new chamber and housing shape combination.

Largescale integration of the all-new electronics, through the fully automated surface mount PCB assembly, coupled with inline testing through the manufacturing process, laser PCB cutting along with a completely new compound of plastic offers improved quality and reliability. All OPAL detectors are environmentally friendly and meet the WEEE and RoHS legislative requirements, minimizing end of life disposal costs, and are mechanically and electrically backwards compatible with existing devices.
