Product details
The Fike TwinflexPro² 4 zone fire alarm panel (505-0004) is an intelligent 2-wire fire alarm control panel that puts detectors, call points and sounders on the same pair of wires, cutting installation time on small and medium sites.
The Fike TwinflexPro² 4 zone fire alarm control panel (505-0004) is the control panel for the Fike Twinflex intelligent 2-wire fire alarm system. The system uses a conventional cabling format but is classed as analogue non-addressable, and allows detectors and sounders to be connected on the same pair of wires, making it well suited to smaller applications such as shops, offices, schools, nursing homes, B&Bs, museums and restaurants. The 4 and 8 zone panels can also be fitted with the optional conventional zone card to accept conventional devices on zones 5 to 8.
