AddressableHorn/strobe

I. Product overview

The 991E addressable horn/strobe(horn/strobe for short) is a kind ofproduct manufactured by our company to be used with bus-type fire alarm controlunits. Controlled by a microprocessor, the horn/strobe can realize real-timecommunication with a bus-type fire alarm control unit and receive the controlcommands sent by it. When in a routing inspection, the red status indicatorwill blink; after an accident happens, the horn/strobe will start to operateafter 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 aflashing signal and an audible alarm signal to notify the persons on the scene of the accident that a fire has occurred on thesite and of the necessity to take related evacuation measures, thus preventing thefire 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-typefire alarm control unit is pressed.

The horn/strobe may be used togive 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, officebuildings and stock exchanges, particularly places with low visibility or thepossibility of generation of smoke.

II. Product features

ü   It can realizecomplete electronic coding and in situ rewriting with the help of a coder.

ü   The audiblealarm and flashing alarm may be set freely. In other words, the horn/strobe maygive an audible alarm and a flashing alarm at the same time or separately andit can be adapted to different working environments.

ü   Designed with an upper cover and a lowercover, it can be installed, debugged and maintained conveniently.

ü   It uses multiplesuper bright red LEDs as light sources for visual display, ensuring a strikingdisplay, a longer service life and low power consumption.
