2-wire Analogue Hotel Addressable Smoke Detectors CE Approved
A. Features
1.Automatic compensation function. It can be automatically compensated to improve the reliability of the smoke detector, such as external environment (temperature, humidity, dust, static, etc.) factors caused by changes in performance drift.
2.Built-in product ID code
3.Intelligent judgment, cleaning forecast function
4.Two bus, linkage, nonpolarity
5.Advanced electronic coding technology, improving coding flexibility
6.Two response modes (commonly referred to as algorithms)
Mode 1: Fast response mode. In this mode, the detector will alarm when the smoke concentration exceeds the alarm threshold more than 3 times consecutively. This mode applies to the system debugging installation phase or test phase.
Mode 2: Intelligent response mode. It is conducive to accurately determine the fire alarm signal, reduce false alarm (factory default).
