1. GB9242 series fire broadcast host is the main equipment for emergency broadcast at the scene of a fire or accident. It can notify the scene personnel of the accident and effectively direct or guide the evacuation of the scene personnel; in non-accident situations, it can also input the sound source signal through (Such as other audio source devices such as CD / MP3 players) for background music broadcasting.

2, GB9242 series fire broadcast host display uses LED digital tube and LED indicator. Used to indicate the recording / playback progress and various states. The keys are touch-sensitive keys to switch between functions and the current status is indicated by an indicator.

3, GB9242 series fire broadcast host has a built-in fire emergency broadcast sound source (solidified voice) and two external auxiliary inputs (line Ⅰ, line Ⅱ), which can be switched freely through the panel. The broadcast sound source can also be forced to switch to the emergency broadcast state by an external level trigger signal. After the signal is cancelled, it returns to the state before the switch.

At the same time, the broadcast host also includes two mono output interfaces, which can output the current broadcast sound source to other equipment, such as GB9221 fire broadcast amplifier.

4, GB9242 series fire broadcast host random accessories include special microphones. It can be used for live broadcast in emergency broadcast state, and the broadcast content will be automatically recorded for query; in non-emergency state, it can also be used for live broadcast. At this time, the recording will not be recorded, and other music signals will be automatically recorded during microphone broadcast. inhibition.

5, GB9242 series fire broadcasting host adopts high-quality toroidal power transformer inside, low static power consumption and strong overload capacity; perfect overload and over temperature protection circuit, buzzer alarm when failure occurs; with self-test, emergency broadcast volume preset, etc. Features.

6, the output power is divided into three series of 150W, 300W, 500W.

CCCF 认证。 7, the implementation of the standard: "Fire Control System GB 16806-2006", has passed the CCCF certification of fire product conformity assessment center .
