Ziton ZP7 Isolator base for seven series sensors

ZP7-IB Sensor base isolator

Common to all ZP7 sensors - The Ziton ZP7P-IB common isolator base, allows any Ziton ZP700 analogue sensor to be removed or replaced without disconnecting loop wiring from sensor terminals. Sensors plug into the base unit with a simple twist and lock action, allowing quick and easy removal for cleaning and servicing, or reselection of device type should the usage of the protected area change.

Designed to provide short circuit protection for loop wiring, isolators divide the loop into monitored sections. A total of 11 isolator units (sensor base and stand alone) can be connected along each ZP loop, which together with isolators at the beginning and end (internal to the panel), enable each loop to be divided into a maximum of 12 monitored sections. Where the performance specification of the Ziton ZP3 panel is not to EN54, the number of isolators on each loop can be increased to 16.

Open and short circuit protection - The Ziton ZP7-IB sensor base isolator is intended for use on a "Class-A" return loop wiring configuration. A single zone, or up to 20 detectors or devices (some standards permit up to 32) is located between each pair of loop isolators. In the event of a short circuit fault the isolators on either side of the fault will disconnect the section of cable between them. Devices outside the disconnected section will continue to operate normally. In the event of an open circuit fault on the loop wiring, the control panel operates from both ends, running the line as two spurs and retaining full connection to all devices.

Meeting the recommendations for system monitoring in most local codes (e.g. BS 5839 Part1), the Ziton ZP7-IB isolator base can be used in conjunction with the Ziton ZP760 stand alone isolator to provide short circuit fault protection across all loop configurations.

Locking base option - Adding isolator bases has no affect on loop addressing sensors are individually identified in the normal way by the control panel, with a maximum of 127 line devices on each loop. An optional lock is provided to lock the sensor into the base, preventing removal without a special tool. Situated on the base moulding, an amber LED indicator flashes when the unit is in operation.
