Which device is typically used to manually trigger a fire alarm?

• A. Manual Pull Station
• B. Smoke Detector
• C. Heat Detector
• D. PIV

Answer: (A)

The concept here is manual initiation of a fire alarm by occupants, as opposed to automatic triggering. A manual pull station is the device designed for that purpose: it’s typically wall-mounted near exits and requires a deliberate action—pulling a handle or breaking a cover—to send an alarm signal to the fire alarm control panel. This setup lets people quickly and intentionally alert others when they observe a fire or sense danger, even before automatic detectors respond. In contrast, smoke detectors and heat detectors are automatic initiating devices; they continuously monitor for smoke or high temperature and will trigger the alarm without any human action. A PIV isn’t a manual triggering device and isn’t used to start the alarm, as it serves a different function within the system.
