Fire Alarm Loop Interface

Apollo Fire Detectors has launched a Diversity Loop Interface Unit, approved to EN54: 17, EN54:18 and EN54:25, and also a Survey Kit especially for their Xpander range.

Connecting up to 31 devices to an addressable loop, the upgraded unit provides increased signal integrity. Signals to and from the device are transmitted through internal orthogonal bi-directional aerials, which require no adjustment or maintenance. The device is backwards compatible with existing sites.

The Survey kit allows a more detailed site survey, determining suitability for an Xpander installation and integrity once installed. It provides dB and background noise levels and meets the requirements of BS5839 Part 1 for a site survey.
