BRT-318 is an occupancy sensor switch which utilizes passive infrared (PIR) sensor to detect the heat (in the form of infrared energy) from people moving within a space. It can determine when a space is occupied and turns on or turns off the loads automatically. It is designed for easy installation and retrofit directly fit into standard wall box with no need for the neutral.
Three touch pads to control up to 3 loads;
Manual override; manually turn off any load instantly;
Adjustable delay-off time from 1 minute to 20 minutes
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-318 PIR occupancy sensor switch respectively.
Besides the PIR lens BRT-318 PIR occupancy sensor switch has an LED power indicator and three touch pads on its front. and terminal blocks on its back.
BRT-318 occupancy sensor switch only requires hot wire for installation:
Hot wire (ACL): Coming from the power line with 220V; 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-318 PIR occupancy 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
BRT-318 PIR occupancy sensor switch automatically turns on the loads instantly or turn off the loads with a delay-off time when it determines whether or not a space is occupied. Also pressing each touch pad (LAMP 1 LAMP 2 or LAMP 3) will turn off the load without any delay.
BRT-318 PIR occupancy sensor switch can be used for automatically turning off various loads such as lights fans appliances or other kinds of electrical equipment. They are perfect for saving energy and bringing convenience and safety to our daily life and work. They have wide applications at various locations such as stairwells corridors washrooms offices conference rooms in homes schools laboratories hospitals offices etc.
