Features:
1) The online smoke alarm KD-101A can be included in the same system by a
LEARN button
2) When one of the detectors alarms, it emits the high frequency digital
signal (433.92MHZ), the others receive the same signal and
will alarm together to remind users to take measures
3) It works on the principle that infrared scatters in the smoke to probe the
smoke which is generated by the incomplete combustion at the initial stage
of the fire
4) It consists of photoelectric system, signal processing identification circuit
and alarm circuit. The infrared scatters on the surface of the smoke when
the smoke enters the darkroom of the detector, then the photoelectric
diode receives the scattered light and generates the photoelectric signal
current
5) The photoelectric signal generates the alarm signal after being processed
by the identification circuit, accordingly the purpose of alarm is achieved
6) The product KD-101Ahas a special design, modern and fashion, small
and artistic, and is of convenience to use
