Which device is used to initiate a fire alarm manually?

• A. Manual Pull Stations
• B. Fixed temperature heat detectors
• C. Rate of rise
• D. Smoke detector

Answer: (A)

Initiating a fire alarm manually relies on a device designed for occupant action. Manual Pull Stations are placed near exits and require a person to pull a handle or lever to send a signal to the fire alarm control panel. This action triggers alarms throughout the building and can notify responders, even if automatic detectors haven’t yet activated. The other options are all automatic devices: fixed temperature heat detectors respond when the ambient temperature hits a set point, rate-of-rise detectors trigger on rapid temperature increases, and smoke detectors react to airborne smoke. So, the manual pull station is the device you use to manually initiate the alarm.
