Part No. F03-83060


EVA-STB-SCI is a 4 inch mounting base with short circuit isolator that will protect the detector and allow it to continue communicating in the event of a short circuit fault. When short circuit is detected, LED indicator illuminates and the short-circuit area is isolated automatically. Upon removal of the short condition, the area is automatically connected and reverts to the normal operating condition.

EVA-STB-SCI can be mounted to 3-1/2” octagonal electrical box, or to 4” square or 4” octagonal electrical box when using STBA-ADP optional mounting adaptor. The base is supplied with 4 terminals as standard. The 12 – 20 AWG field wire can be connected to the terminals. EVA-STB-SCI contains a locking screw to avoid unauthorised removal of detectors.
