With all the features of the 5B Universal Base the 5BI Isolator Base allows any or all 800 Series MX 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 stand alone line isolator fitted between callpoints and other ancillaries.
