The positive (red) wire should be connected to the battery, and the negative (black) wire should be connected to a ground point. Make sure all connections are secure and properly insulated. Install the door sensors: Use the mounting brackets provided to attach the door sensors to the inside of each door. The sensor wires should be routed through the weatherstripping and secured with cable ties or zip ties.

Install the shock sensor: Follow the manufacturer's instructions to install the shock sensor in a location that will detect any attempted break-ins or impacts. Connect the wiring harnesses provided to connect the sensor to the control unit. The positive (red) wire should be connected to the battery, and the negative (black) wire should be connected to a ground point on the frame. Test the system: Turn on the ignition and test each component of the alarm system to ensure it's functioning properly.

I recently purchased the Friedland D902 doorbell and it’s been a mixed experience so far. Firstly, the 1 m range wireless transmitter is a game-changer for me as I’m not always near the door when someone comes knocking. It’s great to be able to hear the doorbell from across my apartment.
However, I have to say that I’m not completely sold on the product. It’s just a basic doorbell, and I feel like I could have gotten something similar for a lower price. It doesn’t have any fancy features like video cameras or motion sensors, which I know some more advanced doorbells have these days.
In comparison to other electrical accessories, I would say that the Friedland D902 is pretty standard. It doesn’t stand out in a sea of other doorbells. However, it does what it’s supposed to do, and I haven’t had any issues with it not functioning properly.
The delivery of the doorbell was quick and painless. I ordered it online, and it arrived at my doorstep in Louisville within a few days. The packaging was secure, and the doorbell was in great condition when I opened it.
Overall, I would give the Friedland D902 doorbell a 3 out of 5 rating. It’s nothing special, but it gets the job done. If you’re looking for a simple doorbell with a decent range, then this might be a good option for you.
