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 for terminal connections only.
The base is supplied with 4 terminals that are used depending on the detector heads. The 12 – 22 AWG field wire can be connected to the terminals. EVA-UB4 contains a locking screw to avoid unauthorised removal of detectors.
