Question from customer:
I need a radio system for switching a receiver of an underground garage, by a concrete slab with steel reinforcement and about 30 meters Distance 1st floor. The receiver may be 220 volts. Transmitter I want to act with an external contact. (Connection to a car alarm system).
Answer:
We recommend the 1 channel high power receiver (S1PUA-AC220-ANT2) and long range transmitter with extended wires (CB-2N). The receiver is activated by ac 220V, which is about 2000m working distance with external extended antenna. The wireless RF signal can pass through walls, floors and doors. It works with the long range transmitter, which features in two external wires because connection of two wires is its triggering method.
According to your requirement, we drew a wiring diagram.
Wires on the transmitter should be connected to the contacts of car alarm system.
The normally open contacts A&B of receiver should be connected to the garage door motor. And supply additional 220V power other than receiver.
Setting latched mode to this receiver.
When the contacts of two wires are closed, the transmitter is triggered and then transmits an rf signal “ON” to activate the receiver. After the receiver receives the signal, contacts A&B are closed; the motor starts to work to open the garage door.
When the contacts of float switch are cut, the transmitter is triggered and then transmits an rf signal “OFF” to deactivate the receiver. After the receiver receives the signal, contacts A&B are cut; the motor stops working to shut down the garage door.
