433 / 868MHz Wireless signal amplifier repeater for extending wireless alarm distance between sensor & gsm host

1.If he distance get too long between the alarm host and sensors, it will results in wireless signals 

didn’t be transferred well, you can use this wireless repeater to solve this problem.

2.You just need to install this wireless repeater in the suitable place between alarm host and sensors, and just make the antenna out,  then  connect the power..

3.If the distance between the alarm host and sensors get too long, you can put this wireless repeater in each long distance place.

4.If the wireless repeater didn’t get signals, LED light won’t be on, and it will be on for 2 seconds if get signal successfully.

5.Normally, the distance for wireless repeater to get\transfer signals is 20 to 30 meters, so, the signals can be transferred from sensors to alarm host successfully if within this distance.

1) 433 / 868 MHZ optional

2) Microcomputer control, stable and reliable performance;

3) AC/DC both available, with inbuilt rechargeable Lithium battery;

4) Forward wireless signals to extend wireless transmission distance.

5) Working Power: 12VDC, Backup Battery: 3.7V / 800mA Lithium battery, Charge Time: ≥12 hours

6) Distance can be extended: ≥30M

1*  Wireless signal amplifier

1*  12V adpater

1*  bag of screw

1.You can’t put two or more wireless repeater in the stated distance (As above point #5), or else, it will result in host panel can’t get signals successfully because of frequency interference.

2.When wireless repeater get signals successfully from sensors, it will help to transfer signals to alarm host after 2 seconds, so,  the more wireless repeater you used, the more time it will be took for the signals transfer from sensors to alarm host.
