Manual pull stations generally fall into two main types, single-action, and dual-action. With a single-action alarm box, a person can activate the alarm by simply pulling the handle down. Dual-action alarm boxes require the user to perform two actions to activate the alarm. They may first need to lift the handle before pulling it down. They may need to break a glass panel to access it. On all types, pulling down the handle completes the circuit and locks the handle in the activated position, which sends a notification to the fire alarm control panel to trigger the alarms.
Once a manual pull has been activated, it must be restored to its ready position. This requires a special tool, which is used to open the alarm station. Opening the alarm station allows the handle to revert to its ready position. Once this happens, the station is closed, which will allow the alarm to be reset from the fire alarm control panel.
The placement of fire alarm pull stations is critical to ensuring they provide the protection intended. The requirements for their placement are intended to ensure that occupants leaving any area of the building can quickly and easily find and pull the alarm to warn others of the emergency on their way out and must be accessible for those who may have disabilities.
Manual fire alarm boxes must be tested annually per the manufacturer’s instructions. Annual testing is required by NFPA 72 also. This testing is typically done as part of a more comprehensive testing of the fire alarm system, which is also required annually.
