The new Zerio Plus device has the usual features of the original device with increases in flexibility when running on the Zerio Plus system. Offering the advanced features of the Zerio Plus detector, the unit is housed in an attractive moulding and shares a common foxing and is interchangeable with the existing Zerio Plus detectors. The Combined optical smoke detector and sounder contains a powerful processor and utilizes surface mount technology to achieve the ultimate in performance and reliability. The sounder section utilizes a high output sounder, switch mode power supply and a sensitive narrow band FM receiver. The unit is fully programmable and is capable, as is the usual sounder detector, of being divided into 255 individually controlled areas. Fully configurable by radio, the combined optical smoke detector and sounder stores a unique serial number and length of time in service in its non-volatile memory. With several available tones, which can be changed with a few button presses at the control panel, the system offers flexibility never seen on a wired system. The combined detector is designed to comply with all appropriate sections of EN54.
