  • The SG-991E fire alarm horn/strobe (horn/strobe for short) is a kind of product manufactured by our company to be used with bus-type fire alarm control units. Controlled by a microprocessor, the horn/strobe can realize real-time communication with a bus-type fire alarm control unit and receive the control commands sent by it. When in a routing inspection, the red status indicator will blink; after an accident happens, the horn/strobe will start to operate after receiving a startup command from the bus-type fire alarm control unit. The red status indicator will remain lit and the horn/strobe will give a flashing signal and an audible alarm signal to notify the people on the scene of the accident that a fire has occurred on the site and of the necessity to take related evacuation measures, thus preventing the fire accident from becoming a major one. The horn/strobe may be restored to the monitoring status after the MUTE or RESET key on the bus-type fire alarm control unit is pressed.


  • The horn/strobe may be used to give audible alarms and flashing alarms on the scenes of accidents. It is suitable for places like high-rise residential buildings, public places, hotels, amusement buildings, factories, shopping centers, hospitals, schools, office buildings and stock exchanges, particularly places with low visibility or the possibility of generation of smoke.
