>>Product Description: ZS.SD-NB311 private communication network is based on NB-Iot was independent wireless smoke detectors, using 9V battery laminate, NB-Iot built-in wireless communication module, capable of detecting smoke generated during a fire, a timely alarm, The alarm information is reported to the smart fire monitoring platform in real time. Can be widely used in Internet cafes, dance halls, cafes, leisure halls, residential and other places for fire safety monitoring. >>Main features:  ( 1) Using NB-Iot Internet of Things real-time communication, with security report and abnormal report function, now the alarm occurs, the intelligent fire monitoring platform immediately knows that the police can be dispatched at the first time to minimize losses; ( 2) Using advanced semiconductor components and excellent production technology, stable operation, simple installation, no need for debugging; ( 2) Using a unique optical labyrinth design, it can detect the smoke generated by the combustion of a variety of substances, and has a higher sensitivity to black smoke; ( 3) Built-in buzzer and led alarm light, which emits a strong sound after the alarm; ( 4) It is powered by a 9V laminated battery, which consumes a small amount of electricity and can be kept for one year under normal conditions. >>Main technical indicators: ( 1) Power supply: H6F22 DC9V battery ( 2) Indicator light: red, flashing once every 50 seconds during normal operation ( 3) Alarm sound > 80dB (4) Protected area: 60m2～100m2 The specific parameters shall be subject to the “Code for Design of Automatic Fire Alarm System†( GB 50116). (5) Use environment: Temperature: -10 °C ~ +55 °C Relative humidity ≤ 95%, no condensation (6 ) Shell protection rating: IP30        (7) Dimensions: 105mm in diameter and 53.5mm in height (with base). Smart Fire Platform:  Wisdom fire platform supports smoke detector alarm, fire hydrant monitoring, equipment management and fault inquiry  can. >>How it works: The detector's sensing of smoke is mainly done by an optical maze. There is a set of infrared rays and receiving photocells in the labyrinth, and the angle of incidence is 135 degrees. When there is no smoke in the environment, the receiving tube can not receive the infrared light emitted by the infrared transmitting tube, and the subsequent sampling circuit has no electrical signal change; when there is smoke in the environment, the smoke particles enter the labyrinth to scatter the infrared light emitted by the transmitting tube. The intensity of the scattered infrared light has a certain linear relationship with the smoke concentration. The post-river acquisition circuit changes. The MCU built into the detector determines these changes to determine whether a fire has occurred. Once the fire alarm is confirmed, the detector emits a fire alarm signal. (Red) lights up and the buzzer alarm is activated. >>Installation layout diagram: Layout description Install at least one alarm in each room that is independent of each other. As shown in FIG. Installation location The best position of the detector should be in the middle of the roof, where the detector is closest to each location of the room. When installed on the roof: the edge of the detector should be at least 50 cm from any wall. When installed on a sloping or human roof: the detector should be kept at a certain distance from the roof. When the slope is less than 30, the distance is preferably 0.2m, and more than 30 is preferably 0.3m~0.5m. Installation location and environment to avoid Places where flammable smoke particles are often produced / particularly humid places / places with a lot of dust / close to fresh air entrances or places where wind speed is too fast / close to fluorescent lamps. >>Installation method: >>Product purchase: >>Network certification certificate: Detailed certificate can be found in the honorary qualification of Zhongshan Technology Website
