Will the alarm sound when the hotel lights birthday candles?

There are two situations when the automatic sprinkler system is started. First, the field temperature reaches the spraying temperature of nozzle rupture. The spraying temperature of the nozzle in the hotel is estimated to be 68℃, which is far from being reached by lighting candles.

Secondly, there is a smoke detector in the hotel room, and the alarm system is in an automatic state, which will start the automatic sprinkler system, and the smoke of the candle is far away from the alarm concentration of the fire alarm detector. In order to prevent false alarm, the automatic fire alarm system will be placed in manual position. Therefore, the automatic sprinkler system will not be started.

According to the principle of vocalization, there are:

1, electric alarm: convert electric energy into mechanical energy, and then convert mechanical energy into acoustic energy.

2. Electro-acoustic alarm: tiny audio signals are amplified by low-frequency power and converted into acoustic energy. That is, electronic energy is converted into acoustic energy.

3. Pneumatic alarm: convert electric energy into mechanical energy, and then convert mechanical energy into gas energy. Convert gas energy into acoustic energy.

According to the setting conditions, there are:

1. Fixed alarm: an alarm installed in a fixed place for use.

2. Mobile alarm; An alarm installed on a motor vehicle or used for sports in other forms.
