ABSTRACT:
A method and apparatus for protecting a low voltage system, such as an alarm system, is described. The method and apparatus includes power line surge protector and a plurality of low-voltage surge protectors housed within a common cabinet. The low-voltage surge protectors are mounted in connectors that provide physical support as well as electrical connections. These electrical connections are routed to a set of input and output terminals by a printed circuit board that also provides support for the connectors and terminals. The combination of power line surge protectors and low-voltage surge protectors may help reduce damage to equipment such as an alarm system during power surges, perhaps caused by electrical storms or heavy electrical equipment being operated nearby. Because of the radio frequency noise emanating from the power line and the power line surge protector, a shield is provided that reduces the amount of noise that is transferred to the low-voltage signal paths.
