What is the duration of secondary power supply for auxiliary or remote station systems?

The duration of the secondary power supply for auxiliary or remote station systems is correctly identified as 60 hours. This specification is crucial because it ensures that these systems remain operational during extended power outages, which can occur in emergency situations when primary power sources may fail.

Maintaining power for a minimum of 60 hours allows for reliable communication and operation of vital equipment, ensuring that services can respond effectively and safely. This standard is likely based on industry practices that prioritize extended readiness during emergencies where immediate restoration of the primary power is unpredictable. It helps to provide peace of mind that essential operations can continue without interruption during critical periods.

Understanding this requirement is essential for fire department personnel and operators of auxiliary systems to ensure compliance with safety standards and effective emergency response plans.
