CPS6000 hammer energizer single zone consists of a single high voltage zone. This zone is hard-wired zones, each wired directly from the energizer. The dual and quad-zone units have been designed with a separate high voltage transformer for each zone, so that if one zone is shorted then the other zones still have power. The LCD keypad is used to display system information and to control the energizer. The system is also programmable from the keypad and was designed for ease of installation and maximum security.
