Ziton ZP7 A Series mini isolator unit

A60E-2 Line isolator module

Short circuit protection - The Ziton A60E-2 line isolator provides short circuit protection, for analogue addressable loop wiring. Isolators are connected at intervals along the length of the loop, dividing the wiring into a series of separate monitored sections.

A maximum of 16 isolator units can be connected to each loop, (to meet the requirements of EN54 Pt2) which together with isolators at the beginning and end (internal to the panel), enable a maximum of 17 monitored sections.

In the event of a short circuit, isolators disconnect only the section of cable between the two isolators, located electrically closest to the fault. Devices outside the disconnected section continue to operate normally.

Soft addressing - Open circuit faults are automatically isolated by the control panel, which then operates from both ends running the line as two spurs and retaining full connection to all devices. Isolators do not require addresses, therefore allowing up to the full system capacity of 127 devices on each loop.

Complying with EN54 Part 17, the Ziton A60E-2 Line isolator module is suitable for installation in systems to local codes requiring short circuit monitoring (for example BS5839 Part 1).

Low profile moulding - Separate terminals (2.5mm2 maximum) are provided for loop in and loop out connections together with screen continuity. Housed in low profile mouldings, the isolators are designed to clip directly onto a standard DIN rail fixing. For non DIN rail mounting, units can be installed in a SMB-DIN100 box (one module capacity), or a SMB-DIN100 box (two module capacity).
