1. This smoke sensor can work alone to realize independent alarm at home.
2. To achieve remote control on the phone, smoke detector needs to work with Sonoff RF bridge( 433Mhz, EV1527) host.
3. Because of shipping limitation, battery( DC9V 6F22 ) for smoke detector not included.
Features:
1. Support three alarms: independent sound & light flash alarm, wireless 433 transmission network alarm.
2. Full snap-in patented structure, simple installation, no need for debugging and wiring.
3. 360 degrees smoke detection and alarm, no dead angle, reliable.
4. Built-in high-sensitivity sensing technology, reliable and safe.
5. Built-in 90 dB sound and light alarm reminder, effectively prompting people to evacuate.
6. Ultra-low-power microcontroller + photoelectric principle technology, long standby life battery use for 3 years.
7. Adopt high-performance photoelectric two-way scattering patented technology of two-receiving & one-transmitting, stable, reliable and accurate.
8. Low Voltage Alarm: When the battery voltage is lower than 6.8V, a warning sound is issued to remind the user to change the battery.
9. Rotary detachable top cover design to facilitate cleaning and battery replacement.
To add a 433MHz smoke sensor, please install the battery into the sensor. Make sure Sonoff bridge is connected with home wifi already.Then
click Add RF Remote on RF Bridge device on app, select Alarm and confirm. You’ll see a new alarm icon is added to APP. Press and hold its
icon, you’ll hear a beep sound from the RF Bridge, the red led of RF Bridge will start fast blink, which means it has entered into learning mode.
then please press the round button of smoke detector until you hear continious alam sound to transmit signal. You’ll hear two beep sounds,
and the red led of RF Bridge will blink twice. This means the PIR sensor has learnt successfully.
