Hi, I'm Tom. Welcome to our shop,
Carymart offers you the premium rf remote control equipment.
We suggest you reading our FAQs before making your decision.
If you have any other question, please contact us.
We will reply you as soon as possible.
Introduction:
This receiver has an adjustable time delay function. You can set its relay
to turn off automatically after a delay time of 5, 10, 15 or 20 seconds.
When you set the delay time, the devices connected to the receiver will
automatically stop after the delay time.
This receiver can be used in one-transmitter-many-receivers system. For
example, you can use a 1 button transmitter to control 1 receiver, or use a
2 buttons transmitter to control 2 receivers, or use a 4 buttons transmitter
to control 4 receivers, or use a 6 buttons transmitter to control 6
receivers, or use an 8 buttons transmitter to control 8 receivers, or use a
12 buttons transmitter to control 12 receivers, or use a 15 buttons
transmitter to control 15 receivers.
Application:
This receiver is an electric device with dry relay output, it and the
transmitter form a wireless remote-control system. This system may be used
in all types of industry automation, agriculture, business, home, factory,
house, farm, garage, vehicle, ship, aerial vehicle, etc. It can remote
control different AC or DC equipment on land, water, and air, such as
lights, doors, windows, lamps, sockets, locks, sirens, outlets, heaters,
motors, fans, winches, curtains, blinds, linear actuators, electric solenoid
valves, and security alarm systems. The applications are endless.
Feature:
Wireless control, easy to install.
DC 5~28V operating voltage range.
Relay Output: This receiver has dry relay output; it can be used to operate
both DC and AC equipment. The output terminals are NO / NC (normally open /
normally closed), serving as a switch. That means you should also connect a
separate power supply to equipment.
It can work at maximum current 10A.
With time delay function, you set its relay to turn off automatically after
a delay time of 5, 10, 15 or 20 seconds.
The transmitter / remote can control the receiver from any place within a
reliable working distance.
Wireless RF signal from the transmitter can pass through walls, floors,
doors, or windows, but it will lose some operating range.
The receiver can store up to 20 transmitters with different codes.
The receiver can only be triggered by paired transmitters.
Two or more receivers may be used in the same area.
One or more transmitters / remotes can control one or several receivers
simultaneously.
You can use one transmitter to control multiple receivers, and each
transmitter button controls one receiver. For example, you can use a 2
buttons transmitter to control 2 receivers, or use a 4 buttons transmitter
to control 4 receivers, or use a 12 buttons transmitter to control 12
receivers, etc.

Working Range:
This receiver and different transmitters form a complete set, which can
achieve different working distances. For example, when it and the
transmitter C-1 or C-2 form a complete set, the maximum working distance may
reach 100 feet or 30 meters in an open area. When it and the transmitter
CB-1 or CB-2 form a complete set, the maximum working distance may reach
1000 feet or 300 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.
The receiver equipped with an external antenna has a larger working range
than the receiver equipped with an internal antenna.
If you need a longer working distance, you can replace the antenna on the
receiver, or use an RF signal repeater, or use a powerful transmitter, such
as a CB-1 / CB-2 transmitter.
Usage:
The receiver can be used to control both 0~28VDC and 110~240VAC devices.
Notice: The receiver is relay output, not DC/AC power output. Initial state
of relay output terminals: Terminals COM and NO are Normally Open; Terminals
COM and NC are Normally Closed.
Wiring:
1) If you want to control a DC 12V lamp, do as follows:
1.1 Connect the positive pole of DC power supply to terminal +V, and
connect the negative pole of DC power supply to terminal -V.
1.2 Connect terminal NO to the positive pole of DC power supply, connect
terminal COM to the positive pole of DC lamp, and connect the negative pole
of DC lamp to the negative pole of DC power supply.
2) If you want to control an AC 120V lamp, do as follows:
2.1 Connect the positive pole of DC power supply to terminal +V, and
connect the negative pole of DC power supply to terminal -V.
2.2 Connect terminal NO to the live wire of AC power supply, connect
terminal COM to one side of AC lamp, and connect another side of AC lamp to
the neutral wire of AC power supply.
Setting different working modes:
The receiver will be set in Self-locking mode before leaving the factory, if
you want to use another mode, please follow the following steps. When
switching working modes, you need to clear the transmitter code stored in
the receiver first.
1) Setting Momentary mode and pairing the transmitter:
1.1 Press the learning button once, the signal LED on the receiver flashes
once and then stays on, it means the receiver enters the learning state.

Press the learning button 7 times, the signal LED on the receiver flashes 7
times and then stays on, it means the receiver enters the learning state.
Press the button you want to use on the transmitter, if the signal LED
flashes 3 times, it means this button pairing is successful.
The operation of Time Delay mode with the transmitter C-1:
Press the button on the transmitter once: The relay in the receiver is
activated, and the connected lamp is turned on.
After the selected delay time, the relay is deactivated automatically, and
the connected lamp is turned off. Note 1: During the delay time, you can also press the learning button in
the receiver to immediately turn off the relay.
Note 2: If you press the transmitter multiple times during the delay time,
the delay time will be counted from the last operation of the transmitter.
How to delete all transmitters codes stored in the receiver:
We have paired the transmitter to the receiver, if you don’t want the
receiver to work with the transmitter, you can delete all transmitters codes
stored in the receiver.
Operation: Press and hold the learning button in the receiver for 6 seconds,
until the signal LED flashes 3 times and then turns off, at this time
release the learning button, this indicates that all stored codes have been
successfully deleted.
