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.
Product Layout
The sensor consists of two parts; a sen sor module and a transmitte r module The
transmitter module can be detached by twisting it clockwise against the sensor

Mounting the SF804-0
The detector is designed for use in a single family home or apartment. For
complete coverage, it should be installed in all rooms, halls, storage areas,
basements and attics in each family living unit. Minimum coverage is one
detector on each floor and one in each sleeping area.
1. Remove the mounting bracket ⑪ from the detector by rotating it
counterclockwise.
2. Use a 5mm drill bit to drill two holes and insert the provided plastic wall plugs.
3. Use the two screws and provided plastic wall plugs to attach the bracket to the
wall.
4. Line up the slot of the bracket and the d etector. Push the detector onto the
mounting bracket and turn it clockwise to fix it into place. Pull outward on the
detector to make sure it is securely attached to the mounting bracket.
Tamper Protection
Tamper switch is set inside the housing of SF804-0 to prevent it from being
forcibly removed.
Maintenance
1. One 9V alkaline battery is supplied in the SF804-0. Replace the battery
once a year. When battery level drops, the detector will beep once every
30 seconds and emit radio signals to the gateway. When this occurs, the
battery should be replaced immediately.
2. Clean and vacuum the dust off the detector’s sensing chamber with a soft
cloth when changing the battery.
