Product overview
The ZP7-IB2-P isolator base protects Ziton addressable fire detection loops against short circuits. Up to 127 base isolators may be connected to each loop when this isolator is used in enhanced mode. For legacy systems the ZP7-IB2-P also support the old operating modes and are therefore backwards compatibility with legacy isolators.
Just as with a standard base, the ZP7-IB2-P allows the detector to be removed or replaced without disconnecting loop wiring from the detector.
Regulatory Loop Protection
The ZP7-IB2-P is intended for use on Class-A, return loop wiring configurations. By regulation a zone of no more than 32 fire alarm devices must be located between isolators. In the event of a short circuit fault the isolators on either side of the fault disconnects the section of cable between them. Devices inside the zone get disconnected, but devices outside the disconnected zone continue to operate normally.
The ZP7-IB2-P meets the recommendations for loop monitoring in local codes like BS5839-1.
Isolator design
With the improved design of the ZP7-IB2-P it is now possible to ensure that no devices are disconnected from the isolated section of cable, that could be a small as the cable between two isolator bases. Every detector may be fitted with an isolator base, ensuring maximal device operation even in the event of a cable short circuit.
Additional advantages
Adding ZP7-IB2-P isolator bases has no affect on device addressing for that loop as they require no addressing. A selectable lock facility is provided to lock the detector into the base preventing removal without a special tool.
Situated on the base moulding, an yellow LED indicator flashes when the isolator is activated.
