Fig. 1 and Fig. 2 show the front view and the back view of BRT-321 PIR vacancy sensor switch respectively.
Besides the PIR lens BRT-321 PIR vacancy sensor switch has an LED power indicator and three touch pads on its front. and terminal blocks on its back.
BRT-321 vacancy sensor switch 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 wires: 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.
Cautions:
1. Avoid mounting the sensor switch close to air vents as the vibration and air flow can reduce the effectiveness of the sensor switch;
2. Avoid installing the sensor switch in an electrical circuit which has other frequent on/off switch or appliance as those on/off actions could cause false triggers.
BRT-321 PIR vacancy sensor switch needs a warm-up time about two minutes before it can
operate properly. For the first time operation the user can set the delay-off time by using 3 dip
switches on its top side as shown in Fig. 5.
Adjust the delay off time
The 3 dip switches are used to set the delay off time to 4 settings ba
Fig. 6 shows all the dip switches are in “off” positions. Each combination corresponds to a delay
off setting.
Turn on or turn off loads manually: Pressing each touch pad (LAMP 1 LAMP 2 or LAMP 3)
will turn on the load and pressing it again will turn off the load.
