The multifunctional voice and light alarm HQSG, also known as the sound and light alarm signal, is designed to meet the special requirements of customers for alarm loudness and installation location. Simultaneously emit both sound and light alarm signals. Product specific fields: steel metallurgy, telecommunications towers, lifting machinery, engineering machinery, port terminals, transportation, wind power generation, ocean going vessels and other industries; It is a component product in the industrial alarm system. Working principle 1: Sound and light alarm is a type of sound and light alarm device installed on site. When a fire occurs on site and is confirmed, the fire sound and light alarm installed on site can be activated by the fire alarm controller in the fire control center, emitting a strong sound and light alarm signal to remind on-site personnel to pay attention. 2. The sound and light alarm utilizes a sound effect chip to amplify through a transistor and transformer, pushing the speaker to emit sound; Using a timing circuit to control the ultra high brightness light-emitting diode to emit a flashing light signal. When a fire occurs on site and is confirmed, the fire sound and light alarm installed on site can be programmed and activated by the fire alarm controller in the fire control center. 3. The naming of the sound and light alarm is based on the way the alarm sounds. The Oracle Security Alarm Equipment Factory sound and light alarm refers to the high decibel alarm sound emitted by the alarm when an intrusion is detected, and the flashing light is used to deter thieves and remind residents, neighbors, and security personnel of illegal intrusion. 4. Sound and light alarms are generally combined with infrared detectors and door magnets to form an sound and light anti-theft alarm system. When the infrared detector or door magnet detects an intrusion, it immediately sends an alarm signal to the sound and light alarm, which will immediately sound an alarm. 5. A sound and light alarm is an alarm signal device used in hazardous areas, which sends warning signals to people through sound and various lights without igniting flammable and explosive gases. It can simultaneously emit both sound and light alarm signals< br/>
