The BiWire Flexi panel combines two technologies to provide a truly versatile fire safety solution.
The panel can be configured to allow either two-wire or conventional devices to work on a zone. Each zone is individually configurable so a mixture of types can therefore be installed on the same system. This provides you with the flexibility to utilise all the time-saving benefits of a two-wire system with the ability to use a wide range of conventional devices, where required.
It shares the same straightforward, intuitive interface as the 8 Zone conventional panel, providing a proven solution for simple programming and maintenance. The BiWire Flexi fire alarm system is certified to EN54 parts 2 and 4 and is designed to meet the recommendations of BS 5839.
Whether you are fitting out a building extension, retrofitting an outdated system with limited knowledge of the original installation or looking to benefit from the cost and time benefits of two-wire technology on a new build and still want to utilise conventional devices; BiWire Flexi gives you the power to adapt the system to the site. Projects change, your panel doesn't have to.
