Long Range 500m Transmitter Triggered by 12V 24V DC Power ON OFF (Model: 0023005)

Package Include:
1 x Transmitter: CK-DC
1 x User manual

Working Principle:
Transmitter CK-DC is a special remote control that is triggered by 12~24V DC Power ON and OFF conditions. It has 2 input wires for connecting an DC voltage signal from an equipment, such as outlet, warning host, detector, sensor, Programmable Logic Controller, DC siren, DC light or other DC equipment.
When an DC voltage is supplied to its input wires, it will transmit a wireless signal "ON". When the input wires stop getting DC voltage, it will transmit a wireless signal "OFF".

Application:
You can use this transmitter and the receiver to remotely control the AC or DC devices by the DC voltage signal of another device. Such as wireless lighting synchronization system. You can connect an DC lamp in parallel to the input wires of this transmitter, and connect another DC lamp to the receiver, then two lamps will work synchronously.
When the first DC lamp is turned on, the transmitter will emit a wireless signal "ON". When the receiver receives this wireless signal, it will activate its relay to turn on the second DC lamp.
When the first DC lamp is turned off, the transmitter will emit a wireless signal "OFF". When the receiver receives this wireless signal, it will deactivate its relay to turn off the second DC lamp.

Feature:
Wireless control, easy to install.
Triggered by 12~24V DC Power.
Wireless RF signal can pass through walls, floors, doors or windows.
Reliable control: The signal has thousands of different combinations, and the receiver only works with the transmitter which use the same code.
Waterproof: The transmitter has waterproof case and waterproof connector, it can be installed outdoors.
One/several transmitters can control one/several receivers simultaneously.
You can use two or more units in the same place.

Transmitter Parameters:
Model: CK-DC
With 2 input wires.
No batteries are required for operation.
Triggered by 12~24V DC voltage signal.
Triggering method: When the input wires get the DC voltage signal, after 1 second, the signal LED on the transmitter flashes slowly once and then flashes quickly, the transmitter sends a wireless signal "ON". After the transmission is completed, the signal LED keeps flashing slowly. When the input wires lose the DC voltage signal, the transmitter immediately sends a wireless signal "OFF". After the transmission is completed, the signal LED flashes slowly for 30 seconds and then goes out.
Signal Transmission Time: 1 second
Operating Frequency: 433.92MHz
Encoding Chip: PT2262 / SC2262
Transmission Distance: 500m / 1500ft (theoretically)
PCB size: 56 x 45 x 19 mm
Case size: 83 x 58 x 34 mm

Working Range:
With a receiver to form a complete set, the maximum working distance may reach 600 feet or 500 meters in an open area.
The maximum working distance is based on theoretical data without obstacles and any RF interference. In practice, it will be hindered by trees, walls, or other construction, and will be interfered with by other wireless signals. Therefore, the actual working distance may not reach this maximum distance.

Usage and operation:
If you want to control the device A by the 12V / 24V DC output signal of the device B, do as following:
1. Connect the device A to the receiver's output terminal.
2. Connect the DC output terminal of device B to the input terminal of the transmitter.
3. When device B outputs an DC signal to the transmitter, the transmitter will emit a wireless signal "ON". When the receiver receives this wireless signal, it will activate its relay to turn on the device A.
4. When device B stops outputting an DC signal to the transmitter, the transmitter will emit a wireless signal "OFF". When the receiver receives this wireless signal, it will deactivate its relay to turn off the device A.
