Installed as part of a Ziton addressable system, up to 127 devices (call points, detectors and interface units) may be connected to each of the control panel loops. All loop devices incorporate switch settings enabling them to be assigned a unique address which is polled by the panel every two seconds.
ZP785-3 call points are designed for semi recessed fixing, using a standard single gang socket box, or can be surface mounted by means of a DMN787 matching plastic back box. Push in terminals enable the device to be plugged directly into the loop, making replacement simple and reducing internal cable ends to a minimum.
System testing, glass replacement and device reset are carried out by using a special maintenance tool. This tool enables part of the front moulding including the glass to be lowered, allowing the device to operate.
