Package Include:
1 x Transmitter: CB-2V
1 x User manual

Working Principle:
Transmitter CB-2V is a special remote control with DC voltage signal trigger. It has 2 input wires for connecting a DC voltage signal from an equipment, such as warning host, detector, sensor, Programmable Logic Controller, DC siren, DC light or other DC equipments.
This transmitter can be combined with different types of receivers (In addition to the 5000m receivers) to form a wireless control system, and this system is used to wirelessly control the device A through the DC voltage signal of the device B.

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 siren synchronization system (see attached diagram). You can connect two wires from a DC siren to this transmitter, and connect another DC siren to the receiver, then two sirens will work synchronously.
When the DC siren is turned on, the transmitter automatically emits a wireless signal "ON". When the receiver receives this wireless signal, it will turn on another DC siren.
When the DC siren is turned off, the transmitter automatically emits a wireless signal "OFF". When the receiver receives this wireless signal, it will turn off another DC siren.

Feature:
Wireless control, easy to install.
Triggered by 5~28V DC signal.
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 No.: CB-2V
With 2 input wires (+, -)
Triggered by 5~28V DC signal.
Triggering method: When input terminals get DC voltage signal, it will send wireless signal "ON". When input terminals lose DC voltage signal, it will send wireless signal "OFF".
With two buttons: red button and black button
Operating Voltage: Operating Voltage: 9V (1 x 6F22-9V battery, 9V Ordinary battery can be used for a week, 9V Rechargeable Lithium Battery can be used for two weeks, if you want a longer working time, please use a 9V power adapter.) 
Operating Current: 30mA
Operating Frequency: 315MHz
Transmitting Distance: 1000m / 3000ft (theoretically)
It has a power switch on the side.
Unit Size: 135mm x 42mm x 25mm

Working Range:
With a receiver (such as S1UA-DC-ANT3) to form a complete set, the maximum working distance can reach 2000M in an open ground.
The maximum working distance is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, it will be hindered by trees, walls or other constructions, and will be interfered by other wireless signals. Therefore, the actual distance may not reach this maximum working distance.

Usage:
If you want to control the device A by the DC 5~28V signal of the device B, do as following:
1. Connect the device A to the receiver.
2. Connect the device B to the transmitter's input wires.
3. When the device B is turned on, the transmitter automatically emits a wireless signal "ON", which is equivalent to the function of the red button on the transmitter. When the receiver receives this wireless signal, it will activate its relay to turn on the device A.
4. When the device B is turned off, the transmitter automatically emits a wireless signal "OFF", which is equivalent to the function of the black button on the transmitter. When the receiver receives this wireless signal, it will deactivate its relay to turn off the device A.
5. You also can press red button or black button on the transmitter to turn on / off the device A.
