The “Main” to “Reserve” Switch is used with systems that incorporate main and reserve (back-up) agent storage. The switch may utilize 1 or 2 Form “C” Contact blocks which will provide an electrical path to either the “Main” or “Reserve” agent release modules.

Following a system discharge, reset any field devices. Once all devices are in a stand-by status, the Main-Reserve Switch may be moved to the “Reserve” position. The Control Panel may then be reset to a normal mode for uninterrupted LIFECO protection. The empty “Main” containers can be removed for recharge. After the containers in the “Main” system have been recharged, the switch may be returned to the “Main” position. The switch may be mounted to a standard 4” electrical box or others.
