BRT-801 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 where both the
“hot” wire and the neutral wire are present.
High power. Loads up to 2000W;
Adjustable delay-off time from 2 minutes to 60 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-801 timer switch respectively.
The switch has a sound detector and a light detector on the front and dip switches for setting up
delay-off time and terminal blocks for wiring on the back.
BRT-801 timer switch only require both hot wire and neutral wire for installation:
Hot wire (ACL): Coming from the power line with 220V;
Neutral wire (ACN): Usually coming with the hot wire; 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.
There are 4 dip switches on the back of the switch. These 4 dip switches are used to set the delay
off time to 8 settings ba
“off” positions. Each combination corresponds to a delay-off time setting.
(Other factory settings are available. Please talk to our sales representatives).
2. Adjust the ambient light brightness threshold
There is a tuning screw on the 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.
Please note that BRT-801 timer switch needs 2 minute warm-up time before it can work normally.
And it is recommended that the switch not be used in noisy environment.
BRT-801 timer switch can be used for automatically turning on and turning off various loads on
sound triggers. Its high power capability makes it especially suitable for driving multiple loads
simultaneously.
BRT-801 timer switch is perfect for saving energy and bringing convenience and safety to our
daily life and work. It has wide applications at various locations such as balcony stairwell
washroom and other public places.
