Underground Garage Door is Controlled Car Alarm System

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.

Latched Mode Remote Controller Apply for Device Control Another Device (Float Switch control Water Pump)

Question from customer:
When the tank is empty my float switch makes contact and stays in this mode till the tank is full.
What I need is for the transmitter to activate the receiver and hold it in the on position till the float switch interrupts the transmitter and releases the receiver. I need a receiver which is only activated as long as the transmitter sends a signal. Or I need a way to make the transmitter send a signal when the float switch makes contact, then interrupts this signal and sends a second signal when the float switch interrupts contact.


Answer:
We recommend the model of normally open latched 2000m remote controller (S1L-DC12-ANT2 & CB-2N). The receiver is with magnetic antenna and only one working mode—latched mode. It is activated the 12V power. The transmitter is designed with novelty. There are two wires extending from transmitter. The triggering method is connection and disconnection of two wires. When two wires are connected, “ON” signal will be sent out. When two wires are connected, “OFF” signal will be sent out.

Wires on the transmitter should be connected to the contacts of float switch.

The normally open contacts B&C of receiver should be connected to the water pump.

When the tank is empty, the contacts of float switch are closed, the transmitter is triggered and then transmits an rf signal “ON” to activate the receiver. After the receiver receives the signal, contacts B&C are closed; the pump starts to work.
When the tank is full, 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 B&C are cut; the pump stops working.

220V Transceiver Turn on/off LED Lamp Via Transformer

Question from customer:
I want to put a 220v Transceiver to turn on / off the power of a transformer of led lighting (to avoid the transformer is always on), this will make me a remote control switch. I want a basic on / off function product.
Answer:
1 channel ac power direct output remote switch (S1X-AC220+C-2) is suitable for you. Its remarkable feature is ac power direct output, that is to say, you don’t have to supply additional power to being controlled device because it can get power from powered receiver. It controls lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances with AC 100~240V range. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance (about 100m); the wireless RF signal can pass through walls, floors and doors.

Wiring diagram is here. Wire transformer to L&N terminals of “OUT “ terminal. Then wire lamp to the transformer.

To avoid transformer being always on, you can use transmitter to remote control it. There are three working modes in it. They are toggle, momentary and latched modes. Here, you can choose latched because there are two buttons of transmitter.
Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.
Press button 1: Turn on the transformer, terminal OUT outputs AC power to switch on lamp.
Press button 2: Turn off the transformer, terminal OUT no output to switch off lamp.

1 Channel AC Remote Controller for Contactor

Someone would like a remote control to switch on and off his lamp via controlling a contactor. He drew a picture to illustrate his idea. Maybe it is not so convenient to him to remote control lamp directly, so he choose to control his lamp via a contactor.

We recommend him a 1 channel AC remote switch with memory function (S1MU-AC220+C-2). This 1 channel ac rf memory remote controller operates in toggle, momentary and latched control mode (set the mode as you like freely). With function of memory, if the power is cut off, the relay will return automatically to the previous status after the power is restored. It is great for hard to reach lights or other electrical devices, remote distance up to 100m (theoretically). It is applied to control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with voltage AC 110~240V or DC 0~28V.

According his requirement, we have this following diagram. Initial state: A, B = Normally Closed; B, C = Normally Open. Wire contactor to normally open contact B&C terminals. And Wire a lamp to contactor and install a switch for lamp (See the original picture).

There are 3 working mode of remote control. They are toggle, momentary and latched modes. We suggest that he should set latched mode because this remote works with a 2-button transmitter.
Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.
Control mode Latched: Press -> On, another relay Off; Press another button -> Off.
Press button 1: Turn on the contactor to turn on lamp (connect B and C, disconnect A and B)
Press button 2: Turn off the contactor to turn off lamp(disconnect B and C, connect A and B)

0~28V or 110V~240V Device is Remote Controlled by 8 Transmitters and One Receiver

Question from customer:
I want to install a set of wireless remote controls, include 8 transmitters in 8 different places (max. 500 m) and one receiver in a specific location. The transmitter transmits a wireless signal to control a closed contact.
Answer:
We recommend normally open/closed contact toggle remote control (S1T-DC12-ANT2+CB-1). According to your requirement, you can choose 8 transmitters (CB-1) to work with the receiver. There are normally open/closed contacts in it which are able to connect device activated by DC 0~28V or AC110~240V. With external extended antenna, its working distance has reached 2000M in the open field. You can use 8 transmitters to remote control receiver from different directions.

This kind of remote control is activated by DC12 power supply. Toggle Mode is the only working mode of it. Here is the wiring diagram. Initial state: A, B = Normally Closed; B, C = Normally Open. Wire your device to normally closed contact A&B terminals. If you do this, your device is turned on always, that is to say, your device will on work all the time.

When you press button on the transmitter (connect B and C, disconnect A and B), turn off device; When you press button again (disconnect B and C, connect A and B), turn on device.

Remote Control 2 Lamps 100M 3 A—Latched Mode

When you want to remote control one more AC devices, you may think about 2 channel remote receiver. This kind of Latching 2 channel remote switch (S2L-AC110~240V + C-1) may be suitable for you. It is activated by AC110V~240V power supply, so being controlled devices will get power from powered receiver. The maximum current output is 3 ampere. The Coding type of receiver is learning code. You can remote control any electric devices within 100M (No obstacles).

Look at the following wiring diagram. We try to introduce 2 lamps controlling of this kind. First, we connect the neutral wire to the terminal “1”, and the live wire to the terminal “2”. Second, we connect the lamp 1 to the terminal “5” and the neutral wire. Third, we continue to connect the lamp 2 to the terminal “4” and the neutral wire.

Latching mode is the only working mode of this remote. So we can do the following operation.
1) Press button C: Turn on the lamp 1, turn off the lamp 2.
2) Press button B: Turn on the lamp 2, turn off the lamp 1.
3) Press button A: Turn off the lamp 1 and the lamp 2.
You can remote control any AC electric appliances other than lamps. It is very convenient to you because you don’t have to supply any power to controlled appliances.
