How to surge protect an access control system?
Surprisingly, the design of security systems oftentimes does not include surge protection. Yet, the simple implementation of surge protectors to protect life safety and security devices so they continue operating without interruption is overlooked. Luckily TPD surge protection can be easily and cost-effectively added to almost any security system. Surge protect the breaker panel feeding the security system or place a 120V hardwired surge protector directed in front of the security panel. It is also recommended to surge protect potentially damaging communication pathways. This could be communication wires between security panels or from cameras, entry turnstiles, motion sensors, card readers, electric strike door lock, keypad door locks, magnetic contact sound alarms etc. It is most common for surge damage when these lines leave the building. It is also recommended to protect problems areas or long runs that connects security panels that are powered from a separate breaker panel. In the the latest 2020 NEC code it is required to correctly terminate and or surge protect all data lines when they leave and reenter a building or structure.
