FT991 addressable horn/strobe is a kind of product 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.
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.
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.
Technical parameters
1.Executive standard: GA385- 2002
2.Operating voltage: DC24V (pulse modulation)
3.Operating current: quiescent current: <=1mA (the current consumed by the bus); alarm current: <=120mA@DC24V
4.Operating environment: Temperature: -10C~+55C; relative humidity: <=95% (40C, without condensation)
5.Flushing rate: one time/s
6.Alarm volume: >85dB (measured at a place 3m in front of the horn/strobe)
7.Coding method: Electronic coding
8.Wiring method: Four-wire system, non-polarity two signal buses (L1, L2) and power lines (+24V, GND)
9.Matched host machine: fire alarm control panel (such as MN300)
Address coding: When a horn/strobe is coded, it is unnecessary to disassemble the wire connecting it with the host machine; online coding may be done. The specific method is as follows: Open the cover of the coding setup window, insert the output plug (a four-pin connector) of the coder into the address coding socket (the socket J2 in Fig.2) of the horn/strobe, set the coder with the coding function, compile the correct address code and press the RUN key to complete the address coding. (Note: See the User’s Manual of the coder for detailed operation information.)
The horn/strobe is subject to a four-wire non-polarity connection: Terminals 1 and 2 are respectively connected with the terminals +24V and GND of the DC power supply terminals 3 and 4 are respectively connected with the terminals L1 and L2 of the signal bus of the fire alarm control panel.
