In a fire alarm system that employs automatic detection or water flow devices, which component is required to enable manual alarm initiation?

• A. Glass break detector
• B. Heat detector
• C. Notification device
• D. Pull station

Answer: (D)

When a fire alarm system includes automatic detection or water flow devices, there still needs to be a way for people to trigger the alarm manually if they notice a fire or if automatic detection doesn’t operate. The device that provides this manual initiation is the pull station. It’s placed at accessible locations along escape routes and is designed so someone can quickly activate it by pulling a lever or handle, sending a signal to the fire alarm control panel to start notification devices and notify responders. Glass break detectors and heat detectors are automatic initiating devices—they trigger the alarm on their own when they detect a specific condition (glass break sounds or high temperature), not by being manually operated. The notification device is what actually broadcasts the alarm to occupants; it isn’t used to initiate the alarm itself.
