Description

The 172101 ZP7 Series Addressable Manual Call Point (ZP785 Series) is an addressable call point of stylish design, providing a manual means of initiating a fire alarm on ZP2 & ZP3 addressable systems. Certified to EN54:11, the ZP785-3 is suitable for installations meeting the recommendations of many local codes (e.g. BS 5839:1).

The 172101 ZP7 Series Addressable Manual Call Point unit is operated either by pressing a resettable element or by breaking a frangible glass with finger pressure. Glass elements have clear vinyl coatings on the front surface to prevent operator injury and to inhibit the release of loose fragments as the glass is broken. Both operating elements are easily interchangeable.

Rated at IP24 the ZP785-3 moulding is constructed of ABS plastic and intended for indoor applications. A red LED indicator is prominently positioned on the front of the unit. This LED illuminates when the device is activated.

Installation

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.
