True or False? Primary power should never be unswitched.

The statement regarding primary power should never be unswitched is generally considered true in the context of safety and functionality in electronic security systems. Primary power, which is the main source of electrical power for devices, should typically be switched for several critical reasons.

Having primary power as switched allows for easier maintenance and troubleshooting without the need to disconnect the supply from the source. It provides a safety mechanism that enables technicians to work on systems safely while minimizing the risk of electrical shock or fire hazards. Additionally, if an emergency occurs, being able to quickly cut off power can prevent damage or further escalation of the situation.

In certain specific applications, there may be exceptions where unswitched primary power is acceptable, but these cases are rare and typically involve specialized equipment designed to safely operate continuously without interruption. Thus, understanding the general principle that primary power should be switched aligns with best practices in the field of electronic security.
