4G intelligent fire and smoke alarm, China Mobile Telecom network access license

4G intelligent fire and smoke alarm, China Mobile Telecom network access licenseThe JTY-GM-FL251 vertical photoelectric smoke and fire detection alarm (hereinafter referred to as the alarm, as shown in Figure 1) is mainly used to detect fire smoke. When a fire occurs, the alarm senses the smoke generated by the fire and emits a buzzing signal and a light signal to warn on-site personnel to extinguish the fire or evacuate. The alarm has a built-in microprocessor and adopts advanced backward photoelectric smoke detection technology in China, with stable performance and operation. Powered by lithium batteries, no wiring is required, and installation and use are convenient (as shown in Figure 1). The alarm is suitable for installation in small public places or households. For example, three small places (small stalls, small workshops, small places), family living rooms, living rooms, study rooms, dining rooms, storage rooms, etc. The following places should be used with caution: places with normal water mist and a lot of smoke and dust, such as outdoors, kitchens, bathrooms, etc.

1. Fire alarm function: Install the battery installed alarm on the ceiling of the house. When a fire occurs, the smoke generated by combustion enters the optical darkroom of the alarm, and the alarm can sense the smoke. When the smoke concentration reaches the set alarm threshold, the alarm will sound and light, and those with wireless function will report the alarm information,. 2. Reset function: After the alarm sounds, you can press the "self-test/mute" button on the alarm to reset it and restore it to normal monitoring state. During the reset process, attention should be paid to blowing out the residual smoke in the sensing chamber of the alarm to prevent it from sounding the alarm again. 3. Self check function: When the alarm is in normal monitoring state, press the "Self check/Mute" button to perform self check. The alarm indicator light is on, and the buzzer beeps for 1 second before returning to normal monitoring mode, indicating that the alarm function of the alarm is normal and reporting self checking information. 4. Fault self diagnosis function: To ensure the operation of the alarm, during operation, the alarm can automatically detect faults such as low battery power or serious dust accumulation in the optical darkroom, and provide flashing lights and buzzer prompts. 5 . Anti disassembly function: When the alarm is removed from the base, it will trigger a disassembly alarm, with the buzzer sounding once and accompanied by flashing lights, while reporting anti disassembly information. 6. Mute function: When the alarm generates a smoke alarm, press the "self-test/mute" button to stop the alarm and enter mute mode. In mute mode, the indicator light flashes every 8 seconds and the mute cycle is 1 minute. 7. Auxiliary temperature alarm: When the ambient temperature reaches 55 ℃ or above, a temperature sound and light alarm will be triggered, and the alarm information will be reported.
