[0002] Fire alarm (commonly known as sound and light) is an audible and visual alarm device installed on site, which can be directly connected to the signal bus 2 of the fire alarm controller (commonly known as the alarm host), and needs two DC24V power lines provided by the power system. After a fire occurs and is confirmed on site, the fire sound and light alarm installed on site can be activated by the fire alarm controller (alarm host) of the fire control center, and send out a strong sound and light alarm signal to alert the on-site personnel.

[0003] Currently, the existing sound and light alarms can only sound an alarm and flash when a fire occurs. When the fire spreads rapidly, smoke and dust will block the flash of the alarm, resulting in a weak penetrating effect of the flash and affecting people's observation. Secondly, the existing alarms do not have the function of guiding the direction of the safe exit, so the function of the alarm is relatively simple, reducing the practicality of the alarm.
