Nittan Evolution Addressable Detector Base with SC Isolator (EV-B-SCI)

The Nittan EV-B-SCI (part no. F03-83605) is a low-profile detector base with a built-in short circuit isolator, for all types of Nittan Evolution analogue addressable detectors. It is designed for dry, clean spaces, with cable entry from the centre or the side.

The -ve line isolator works transparently with no settings needed and resets itself when the fault clears. Nittan notes that +ve and -ve isolator styles cannot be mixed on one system, so check panel compatibility with Nittan technical support.
