The working principle of hotel smoke. Whether they work in parallel or in series and how to transmit them to the alarm center.

The smoke detector (probe for short) adopts Yuan Shuang double ionization chamber structure, which can automatically track the ring.

Working point drift caused by environmental change, detection probe aging due to dust accumulation, ensuring its alarm sensitivity.

The temperature is in a stable state, and fire alarm and fault alarm can be effectively carried out. The probe consists of a detection ionization chamber and a reference power supply.

Go out of the room, etc. When foreign smoke (smoke particles) enters the measuring room, the ionized magnetic rays change (electricity

When the value exceeds the specified threshold, the change of the flow rate is converted into the change of the voltage monitored by the electronic system),

Output alarm signal. There are four kinds of alarm signals:

1. Fire alarm: When an object smolders with open flame, smoke and thermal temperature changes, the probe signal lamp will light up and transmit it to the center.

The controller sends out a fire alarm signal.

2. False alarm: In fact, there is no fire, but it is interfered by the outside world, such as artificially spraying cigarettes, burning paper and smoking.

Too much cooking, steam, strong smell, humidity, sultry, electric frequency interference, wind speed exceeding 3m/s, etc.

Cause the alarm system to alarm.

3, false alarm: refers to the probe and system equipment in a short period of time is not affected by any external alarm (after reset

Processing) or multiple alarms in one day; Or current sen between components and line.

4. Fault: refers to the alarm system caused by short circuit, open circuit and component damage during operation.

From the alarm.
