Instruction Manual of ATL-991 Addressable Horn/strobe
------ Please read this Manual carefully before installing and using the product. -----
I. Product overview
The ATL-991 addressable 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 persons 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.
II. Product features
It can realize complete electronic coding and in situ rewriting with the help of a coder.
The audible alarm and flashing alarm may be set freely. In other words, the horn/strobe may give an audible alarm
and a flashing alarm at the same time or separately and it can be adapted to different working environments.
Designed with an upper cover and a lower cover, it can be installed, debugged and maintained conveniently.
It uses multiple super bright red LEDs as light sources for visual display, ensuring a striking display, a longer service
life and low power consumption.
