A manual fire alarm button (commonly known as a manual alarm) is installed in public places. When a fire is confirmed to have occurred manually, pressing the organic glass plate on the button can send a signal to the fire alarm controller. After receiving the alarm signal, the fire alarm controller displays the number or position of the alarm button and emits an alarm sound. The manual fire alarm button, like various coding detectors in the bay, can be directly connected to the controller bus.
