Nittan EVA-UB4 User manual

STANDARD DETECTOR MOUNTING 4” BASE EVA-UB4
■ Description
EVA-UB4 Standard Base is a 4 inch mounting base
for Nittan’s UL listed detectors that can be mounted to
3-1/2 inch and 4 inch octagonal electrical boxes. The
base contains no electrical circuit so that the base is
used as a terminal block. The base is supplied with
4 terminals that are used depending on the detector
heads. The 12 – 22 AWG eld wire can be connected
to the terminals. EVA-UB4 contains a locking screw
to avoid unauthorized removal of detectors.
