Zeta ID2/2/M Infinity ID2 Intelligent 2 Wire 2 Zone Fire Panel in Metal Enclosure

Zeta Alarm Systems is proud to introduce the most advanced 2 wire system on the market. We can now provide a system that gives all of the benefits associated with a ‘2 Wire’ installation (less cable, quicker installation, cost savings on labour/product) and has the facility to ‘I.D.’ the devices.
The system is built on the proven communication protocol developed by Zeta Alarm Systems and shares the same platform as our largest, most powerful system.
The ID2 can be used for new installations, as a retrofit for any conventional system or as a replacement for existing 2 wire systems when the extra features are deemed to be desirable/necessary. This is possible because the ID2 devices sit on radial circuits, thus making it easy to ‘upgrade’ a system with the facility to I.D. devices without the need to re-wire.
