Introduction
VDOT-STB-SCI is a 4 inch mounting base with short circuit isolator that isolates short-circuit to protect a detector failing. 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 to go back to the normal operating status.
VDOT-STB-SCI can be mounted to 3-1/2” octagonal electrical box, or to 4” square or 4” octagonal electrical box when using VDOT-ADP optional mounting adaptor.
The base is supplied with 3 terminals as standard.
The 12 – 20 AWG field wire can be connected to the terminals. VDOT-STB-SCI contains a locking screw to avoid unauthorised removal of detectors.
