The novel building has the characteristics of dense personnel, advanced equipment, multiple functions, luxury decoration and the like, and the loss of human beings caused by building fire is huge.

In practical applications, there are certain requirements on the performance, location and installation of the fire alarm notification units, that is, it is ensured that the notification message, namely sound and light, meet the requirements in a certain area, which may cause two or more fire alarm notification units to be installed simultaneously in a room or an aisle, although these devices are connected to the bus of the same controller, due to the difference of each device, when the fire alarm notification units operate, the flashing of light is always somewhat fast and slow, and if the flashing is not synchronous, the onset of epilepsy and the like is induced, which may cause harm to human bodies, and NFPA 72-national fire alarm code specifies that the fast and slow time between the fire alarm notification units must be within 10 MS.
