·Smoke & dust detector are high-sensitivity photoelectric smoke and dust detector for fast detection of slow, smoldering smoke&fire when danger, designed for a wide range of commercial applications where reliable smoke detection is required. 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. The photoelectric signal generates the alarm signal after being processed by the identification circuit, accordingly the purpose of alarming is achieved. It is widely used in the fields of hotels, shopping malls, apartments and residences, etc.
·Test button for easily weekly testing. ·Infrared photoelectric sensor; strong adaptability for circumstance.
·Low battery signal alarm. ·Alarm output N.C./N.O. optional; network output / LED indicator.
·Ceiling mounting & Easy to install with mounting bracket. ·SMT design, high stability.
·Safety clip feature, not allow mounting without battery installed. ·9-35VDC wide voltage operating range.
