After activation, what is required to return a manual pull-station to its original state?

To return a manual pull-station to its original state after it has been activated, a special key or tool is typically required. This is because manual pull-stations are designed to prevent unauthorized or accidental resets following an emergency activation. The use of a key or tool ensures that only trained personnel can reset the station, maintaining the integrity of the fire alarm system and preventing false alarms.

This process is crucial for fire safety as it ensures that the alarm system remains functional and ready for future emergencies without the risk of unintentional resetting by anyone who might not be qualified to do so. Such measures are in place to ensure that fire safety protocols are strictly adhered to and that systems remain effective at all times.
