Alarm sound pressure: ≥85dBAlarm
Self-detected smoke alarm:
a. Under normal circumstances, smoke is detected once every 5 seconds.
b. When a certain smoke is detected, the smoke detection frequency is adjusted to 1 second for 1 time.
c. The red LED will flash once every time there is smoke.
d. It is detected that there are 5 consecutive smokes, or 5 times after short-term accumulation, the alarm will start.
e. During the first 11 seconds of the alarm, the buzzer will beep intermittently (ringing 0.2 seconds to stop for 0.3 seconds), and the LED flashing (ranging 0.2 seconds to stop for 0.3 seconds). No smoke is detected during the period.
f. 11 seconds later, the buzzer and LED tweet frequency are reduced, all are bright (loud) 1 time per second, and every 3 times.
g. Smoke is detected once every 4 seconds during the alarm. After detecting no smoke for 2 times, exit the alarm state and enter the normal state.
Network interconnection alarm
a. Under normal working conditions, the same network number alarm signal sent by other devices is received, and the network alarm state is entered.
b. Under the network alarm state, the red LED double flashes. The buzzer sounds the same as f.
c. During the network alarm, smoke is detected once every 4 seconds. If smoke is detected twice in succession, the product immediately enters its own alarm state, as in f.
d. In the connected state, press the button and immediately exit the network interconnection alarm and enter the normal state.
e. During the network alarm, the alarm main device stops alarming or enters the mute state, and automatically exits the network interconnection alarm and enters the normal state. The stop alarm time is slightly later than the main alarm device, and the delay is no more than 10 seconds.
Mute
a. In the alarm state of f, press the button to enter the silent mode.
b. In the silent mode, the smoke is detected once in 5 seconds. If there is smoke, the flashing red LED is fast. If there is no smoke, the green LED flashes once.
c. If no smoke is detected within 4 minutes, it will automatically exit the mute state and enter the normal state.
d. Any time a smoke is detected, it will reset for 4 minutes and wait for silence (mute again for 4 minutes).
e. In the mute state, press the button a short time to immediately exit the mute state and enter the normal state.
