Ziton A50E-2 - Miniature addressable Ziton relay - For Ziton ZP3 and Ziton ZP2 Systems
The Ziton A50E-2 is an addressable Ziton relay providing single pole, volt free, change over contacts. The unit is intended for installation within the equipment to be switched, thereby offering savings in installation costs when compared to long, auxiliary circuit, wiring runs out from the control panel. Complying with EN54 Part 18, the relay can be located anywhere on the two core ZP loop and is designed for power up or shut down of building services, for example air conditioning plant, in fire conditions. The unit is ideal for the control of associated system equipment such as door release circuits, or the emergency shutdown of high risk services, for instance gas or oil supply valves in boiler rooms.
Low profile moulding
The relay can be programmed to be activated by any single device, groups of devices or all system devices. All types of system input signals can be arranged to operate the A50E-2, which can include control panel indicators, zonal outputs, callpoints or sensors. Housed in a low profile, double width moulding the interface is designed to clip directly onto a standard DIN rail fixing or be installed in a Ziton SMB-DIN100 box (one unit capacity), or a SMB-DIN200 box (two unit capacity).
A red LED indicator positioned on the front moulding flashes when the interface has operated, providing clear identification of the input signal source. Installed as part of an analogue addressable system, up to 127 line devices (sensors, callpoints or interface units) can 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.
