The Zerio Plus R5100 enhanced radio optical smoke detector from ElectroDetectors represents a new benchmark in terms of what the marketplace can expect from a radio smoke detector. The detector is the latest development from a company which has over 30 years of designing and manufacturing fire alarm systems.

Based on the highly successful Millennium and Zerio ranges, the detector is housed in the original attractive, low profile, moulding. The addressable detector contains a powerful processor, utilising surface mount technology to achieve the ultimate in performance and reliability.

Long operational life, high sensitivity and stable operation has been successfully achieved by using sophisticated protocols and the most technologically advanced components.

Fully configurable, by radio waves, the Zerio Plus detector features programmable sensitivity. A unique serial number and the length of time in service is stored in its internal memory. All data is retained in this non-volatile memory which is not corrupted or erased even should power be removed. A battery life of up to 7 years and sensor recalibration minimise detector maintenance but sophisticated self testing ensure confidence in detector operation.

Zerio Plus smoke detector is fully compliant with the relevant sections of BS5839 and EN54 including Part 25. The detector is supplied complete with its base and battery and just requires two screws to mount the unit on the ceiling.
