BRT-802 is a timer switch integrated with a sound sensor. It automatically turns on the load when
the sound level is above a preset threshold and keeps the load on until a delay-off time runs out.
It is designed for easy installation and retrofit directly fit into standard wall box with no need for
the neutral.
Loads up to 150W;
Adjustable delay-off time from 10 seconds to 15 minutes;
Ambient light override. Automatically measures the ambient light level and there is no sound
trigger on when brightness is above a threshold which is adjustable by end users;
Good for all kinds of loads (an additional adapter required for capacitive lights such as CFL);
ABS-V0 flame resistance material; and
Classical 86 series design and high quality build.
Fig. 1 and Fig. 2 show the front view and the back view of BRT-802 timer switch respectively.
The switch has a sound detector and a light detector on the front tuning screws for setting up
delay-off time and ambient light override on two sides and terminal blocks for wiring on the back.
BRT-802 timer switch only requires two wires for installation:
Hot wire (ACL): Coming from the power line with 220V; and
Load wire: Going to the load.
Warning: Please make sure power is turned off before starting installation!
Fig. 3 shows the wiring diagram and Fig. 4 shows the step-by-step installation instructions. There
are three easy steps:
Step one: Use a screwdriver to pry off the front plate in position A;
Step two: Wiring according to the diagram and the labelled ports of the switch; and
Step three: Install screws and front plate.
Once properly wired BRT-802 timer switch needs two adjustments for the first time operation: set
up the delay-off time and set up the ambient light override.
1. Adjust the delay-off time
There is a tuning screw on one side of BRT-802 timer switch. Use a crew driver to tune this screw
to adjust the delay-off time as shown in Fig. 5. The delay-off time can be set from 10s to 15
minutes.
2. Adjust the ambient light brightness threshold
There is a tuning screw on another side of the switch. Use a crew driver to tune this screw to
adjust the ambient light override threshold brightness as shown in Fig. 6.
