The low air pressure warning alarm will activate when the pressure falls below what value in psi?

The low air pressure warning alarm is designed to activate when the pressure in the air system of a vehicle drops below a specific threshold, indicating a potentially hazardous situation. In many fire service vehicles, this threshold is set at 60 psi. When air pressure falls to this level, it signals operators to take immediate action to avoid air system failure, which could impair the operation of critical systems such as brakes.

This activation is a crucial safety feature, ensuring that drivers are alerted to low air pressure conditions before they become critical. Maintaining awareness of the air pressure levels helps in ensuring the operational readiness and safety of the vehicle, confirming that it can safely perform the required functions, such as responding to emergencies.
