The sprinkler test box is a display and control unit for the electrical monitoring of sprinkler systems. In normal operation, it reports line status of the sprinkler system to the fire alarm panel.

During the periodic inspection of the sprinkler system, the SPB20 prevents the signalization of alarms or faults to the fire panel.
