  • 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-800 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-800 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-800 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 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 based on different combinations. Fig. 5 shows all the dip switches are in

      “off” positions. Each combination corresponds to a delay-off time setting.



      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-800 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-800 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



      BRT-800 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.
