1）JTY-GD-EIN14W standalone photoelectric smoke detector is an internal battery-powered alarm. It can quickly detect the smoke generated during the smoldering stage of the fire, issue a fire alarm signal in time, and send the alarm status information to the mobile phone through the wireless repeater. The detector has a built-in buzzer, it gives a strong sound after the alarm.
2）The products are stable in work, novel in shape, beautiful in appearance, easy to installation and debugging, can be widely used in residential and nursing homes, welfare homes, kindergartens, boarding schools and other places to achieve fire prevention and monitoring.
?Alarm self-test function: After the alarm is connected to the power supply, it can work normally. Press the “Self-test” button, the fault indicator (yellow) lights up a 1 second, and then the fire alarm indicator (red) lights up 1 second, after 1 second, it will go out. After the inspection indicator (green) will light for 1 second and then go out. The buzzer will sound 3 cycles of fire alarm (alternate 1 second ringing and 1 second stop), and the fire alarm indicator (red) Light up.
After the self-test is completed, it enters the normal monitoring state, and the inspection indicator (green) flashes once in about 60 seconds.
?Alarm function: When the smoke around the alarm reaches a certain concentration, the alarm light alarm indicator is always on, and the buzzer sounds an alarm (the period is 1 second and stops for 1 second). After the fire alarm, press the “TEST” button, the alarm will reset, the buzzer will stop sounding, the fire alarm light will go out, and the alarm will be in normal monitoring state. Or the alarm can automatically resume normal monitoring when the smoke around the alarm is dissipated.
?Power under-voltage prompt function: The alarm has battery voltage detection function. When the power supply battery voltage is lower than 2.85 V, the alarm fault indicator (yellow) flashes (0.2 seconds every 40 seconds), and the buzzer emits Short fault alarm sound (0.2 seconds every 40 seconds), indicating battery under-voltage fault.
