Wireless Remote Control Electric Door Locks

Question from customer:
I need one transmitter and 2 receivers that the transmitter operates separately. Preferably 12 volt receivers will work out to 300 yards. I am using the receivers to operate door locks on a project I’m working on.
Answer:
We recommend you 2000m remote control system input & output 12V (S1X-DC12-ANT2&CB-2). One transmitter (CB-2) can pair up with 2 receivers (S1X-DC12-ANT12), so you can use one transmitter remote control two receivers. With external extend antenna, its transmitting distance can reach about 2000m (2187yards) in the open field. It is 12volt actuated, that is to say, electric door lock doesn’t need to be supplied additional power supply because electric door lock will get power from powered receiver.

Wiring is simply easy. Wire your electric door lock to A&B terminals of receiver.

Operation:
Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.
Press big button: Turn on the relay, terminal A&B output DC power, open the door.
Press small button: Turn off the relay, terminal A&B no output, close the door.
