A service panel for limiting access to authorized persons. A sub-region of the service panel controls at least one electrically-operated (e.g., solenoid-operated) valve that is connected to service utilities (e.g., water or gas) piping so as to control flow through the valve. According to one embodiment, another sub-region (i.e., a utility controller region) contains a PCB and other electrical controls for controlling the valve(s) and communicating with other services such as a remote transmitter, or an auxiliary monitoring system (e.g., a fire alarm system). The service panel facilitates the use of advantageous features including: emergency shutdown by anyone while permitting reset only by authorized personnel; modular construction so as to facilitate installation of the system. Various jumper terminals and connecting wires provide for programming of the system to accommodate a variety of applications. |
