Smart DC 24V ceiling mount infrared PIR motion sensor control switch for air conditioner auto control

Features :

BRT-K311 is a ceiling mount remote control 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 unoccupied and

turns off the large loads such as air-conditioners, etc., automatically by sending out IR control signals.

l Capable of learning and memorizing infrared control codes of all kinds of appliances;

l Adjustable delay-off time from 1 minutes to 30 minutes;

l Good for all kinds of appliances that have infrared control, such as air-conditioners, TVs, fans, audios, etc.

l Easy installation onto ceiling with or without a holder;

l ABS-V0 flame resistance material; and

l High quality build.

Installation Guide:

There are two ways to install BRT-K311 PIR remote control to the ceiling. Fig. 4 and Fig. 5 show the step-by-step

installation instructions, respectively.

Cautions:

1.    Avoid mounting the control close to air vents, as the vibration and air flow can reduce its effectiveness;

2.    Avoid installing the control in an electrical circuit which has other frequent on/off switch or appliance, as

those on/off actions could cause false triggers.

1. Installation using a holder

As shown in Fig. 4, a holder is attached to the ceiling using screws first. Then, the PIR remote control can be easily

snapped into the holder.

The  holder  is  specially  designed  for  BRT-K311  PIR remote control. Please  talk  to  our  sales representative when

placing orders.

2. Installation without a holder

As shown in Fig. 5, without a holder, an opening in the ceiling needs to be made first. There are four steps:

Step one:     Open a hole of 68mm in diameter in the ceiling;

(Attach the electrical wires as shown in the Wiring Diagram Fig. 3).

Step two:     Open the two flexible clamps on the side surface of the remote control;

Step three:   Insert the remote control into the hole; and

Step four:    The clamps will hold the remote control onto the ceiling tight and steady.

Operation Guide:

BRT-K311 PIR remote control needs a warm-up time about two minutes before it can operate properly. It has

dip switches for adjusting the delay-off time, as shown in Fib. 6. For the first time operation, BRT-K311 PIR

remote control also needs to learn and memorize the IR remote control codes from regular remote control set.

BRT-K311 PIR remote control has a button for this task as shown in Fig. 6 as well.

As shown in Fig. 7, please rotate the front cover counter-clockwise to remove it so that the dip switches and

the button for code learning are exposed.

2.    Learn the IR remote control codes

Please refer to Fig. 9 and follow the following steps to have BRT-K311 PIR remote control learn and memorize the IR

control codes from IR remote controls sets of appliances.

a.     Turn on power to BRT-K311 PIR remote control, and set dip switch 4 to ON position.

There is an LED flashing behind the PIR lens;

b.     Press and hold the button for code learning until the LED is constantly on;

c.     Point the regular IR remote control of appliance to the PIR lens, and start to send OFF

control signals;

d.     If the LED quickly flashes a few times, code learning has been successfully completed;

e.     To verify if code learning is successful, press the button for code learning to have

BRT-311 PIR remote control send out the control signals it just learned. The appliance

should be turned off accordingly; and

f.     Return dip switch 4 to OFF position.

Now, BRT-K311 PIR remote control is ready to control the appliance automatically.

Applications :

BRT-K311 PIR remote control can be used for automatically turning off various loads which use IR remote controls,

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.
