With all the features of the 5B Universal Base the 5BI Isolator Base allows any or all 800 Series MZX Detectors to be upgraded to incorporate bi-directional short circuit isolation. Implemented on every detector, the 5BI can ensure that no detector is lost on a system in the event of an open or short circuit.
Alternatively, the 5BI can be implemented between zones to provide short circuit isolation according to BS5839 Part 1 and EN54. The 5BI can be used as a standalone line isolator fitted between callpoints and other ancillaries.
Features:
- Variety of Fixing Options
- Remote LED Connections
- Anti-Tamper Facility
