SF804-0
Smoke Detector
Installation Instructions
General Introduction
The SF804-0 Smoke Detector is designed to sense smoke that comes into the
detector’s chamber. It does not sense gas, heat, or flame. When it detects a
certain density of smoke the horn will sound and the RF module will emit signals
to the Gateway. Its great compatibility with our U-Net family security products
makes it suitable for smart home cloud based platforms such as Homesys.

transmitter module can be detached by twisting it clockwise against the sensor
module.
