A range of smoke and heat detectors, designed for connection to a single fire alarm system, is now offered, opening up many new application possibilities.12 NOV 2002
The ZF60 range comprises an optical smoke detector, an ionisation smoke detector, a fixed temperature heat detector and a rate of temperature rise detector. All are designed for use in conjunction with the Bardic Zircon LC and Zircon Multizone fire panels, which are used extensively in light commercial and industrial premises. Up to 20 detectors of any type or combination can be mixed and matched to protect a single zone. This opens up the possibility of using Zircon LC and Zircon Multizone panels in multi-occupancy domestic premises.
Improvements in optical detector technology make optical smoke detectors the preferred choice for a great number of applications. A benefit of using either or both of the new smoke detectors is that, with the inclusion of a common diode base, users can easily spot a removed or faulty detector in accordance with BS 5839.
Where environmentally borne contaminants are present, the use of a smoke detector becomes impractical and the use of heat detection more attractive. The fixed heat detector is more suited for use in places where temperatures fluctuate such as in kitchens, as such a device is less likely to create a false alarm than would a rate of rise detector.
