Đầu báo khói horing AH-0311-2 24V AH-0311-4 12V

*** Chi tiết tính năng kỹ thuật của sản phẩm :
* Operation Theory :
- The infrared light beam from Transmitter intersects the
smoke particles will cause the light spread to all directions.
- When Receiver sensed the light, it will send signal to
control panel for fire alarm status as soon as the density of
smoke reaches pre-determined alarm level.

* Resettable Type Detector:
- This unit is designed for relay output feature with optional
individual power source and it has used widely in the
current market. This resettable detector does not only used
for fire alarm system but also will supervise input power via
optional relay output for power breakdown or wire break,
fault relay contact will open when power breakdown
happened and fire alarm signal will transmitted to
connected system or computer terminal when detector is
activate. When the alarm signal is clear and the detector
will automatically back to standby status. Optional built-in
buzzer could sound for warning purpose at the first stage of
fire. This detector is currently used quite often in security
system and is also promote to apply for communication,
banking, shipping or art business and it still under
development for more applications in the future.
