Installation Notes:  
1. Mount in a convenient location where alert tones and LED indicators will be audible/visible.  
2. Do not install in a location surrounded by metal as RF signals may be blocked, decreasing range.  
3. Do not install in a location exposed to weather, moisture or high humidity.  
To open the housing:  
1. Remove the antenna by unscrewing the antenna base counterclockwise.  
2. Remove the bottom cover starting from point 1 shown in the diagram. Follow with points 2 and 3.  
NOTE: Applying outward pressure on the clip points will help release the bottom cover.  
3. Before attempting to release point 4, gently slide the bottom cover down and left to bring the  
programming buttons out of their holes in the housing.  
4. Disconnect the speaker plug from the PCB to avoid damage  
Clip Points  
while working with the cover off.  
5. When replacing the bottom cover, ensure the speaker wires are  
not caught between the speaker and the PCB. Check that buttons  
and knobs are properly inserted in their openings in the housing.  
NOTE: Buttons and knobs are connected directly to the PCB.  
Be gentle to avoid damaging delicate electronics. Do not  
force the cover on or off if resistance is felt.

Code Learning a New Transmitter:  
Each receiver channel can learn the codes of up to 15 different transmitters. Transmitters are  
learned on a first-in, first-out basis. (For example, if 15 transmitter codes have been learned, when  
a new transmitter is learned the first of the 15 codes that were learned before will be deleted.)  
1. To learn a new transmitter, first press and hold the programming button of the channel to be  
programmed for 3 seconds or more. (Programming buttons are found on the top of the unit.)  
Note: A pencil or other pointed object may be necessary to press the programming buttons.  
2. The channel’s red LED will flash quickly to indicate it is in Learning Mode. DO NOT REPEAT  
STEP 1 WHILE THE LED IS FLASHING OR CHANNEL MEMORY WILL BE CLEARED.  
3. While the channel LED is flashing, press the button of the transmitter being learned one time.  
The channels LED will flash once to indicate the transmitter code was successfully learned.  
4. If no transmitter is learned within 15 seconds, the receiver will return to standby mode.  
5. If the transmitter has been learned already, the channel LED will turn steady ON and the code  
will not be learned a second time.  
Displaying or Clearing a Channel’s Memory:  
Display Channel Memory:  
1. Press a channel’s programming button once.  
2. The number of flashes is the same as the number of transmitters that channel has learned.  
Clear Channel Memory:  
1. Hold down the channel’s programming button for three seconds.  
2. The channels red LED will start flashing.  
3. After the LED has started flashing, hold down the programming button for three more seconds.  
The LED will flash two more times, indicating that all codes learned by that channel have been  
cleared.  
Alert Tones:  
Each channel has a specific alert tone. See the chart on the lower right.  
1. Open the housing following the instructions under Installation Notes on page 3 of this manual.  
2. Locate the Alert Tones DIP switch marked SW7. Switches marked 1 through 4 determine  
whether each channels sound will play when the respective channel is triggered.  
3. If the switch is in the ON position, the alert tone will play when the channel is triggered.  
4. If the switch is in the OFF position, no alert tone will play when the channel is triggered.  
5. Adjust the volume using the volume adjustment knob.

Programming Each Channel Output:  
1. Each channel output can be separately programmed for one of four different modes:  
Timed Output: When the channel receives a signal, the relay will turn ON for 1~60 seconds,  
depending on the output time set.  
Note: The timer, once set, is the same length for all outputs programmed for Timed Output.  
(See page 6 for timer programming.)  
Toggle Output: When the channel receives a signal, the relay will turn ON and remain  
activated until a second signal is received.  
Latch Output: When the channel receives a signal, the relay will turn ON. Turn the relay OFF by  
pressing that channels programming button on the Central Receiver unit.  
Validity Output: When the channel receives a signal, the relay will turn ON for as long as a signal  
is being received.  
2. To enter programming mode, press the button marked Mode on the top of the unit. Each  
channel’s red LED will flash a number of times to show the current output mode that it is in:  
# of Flashes

3. To change modes, press the desired channels transmitter programming button. Each press  
moves to the next mode in the sequence shown in the diagram below. After changing modes,  
count the number of times the channel LED flashes to verify the channel is in the correct mode.

4. When finished, press Mode again to end programming.  
Example 1: If the present mode is Timed Output, and  
the desired mode is Latch Output, press the

If channel is set to Latch Output, press to turn relay off after it has been triggered.  
Press momentarily. The Channel LED will flash a number of times corresponding to  
the number of codes stored.

Setting the Timed Output:  
When a channel is set to Timed Output, triggering the channel will activate the relay for a set  
period of time. Factory default is 1 second.  
1. The time can be set from 1~60 seconds using the Timer switches on the top of the receiver.  
2. Set switches according to the following chart.  
NOTE: The time set via the DIP switches applies to all channels programmed for Timed Output.

Setting the Auxiliary Relay:  
Each channel may be individually set to activate a separately timed 12VDC output programmable  
from 1 second to 10 minutes. The auxiliary relay provides up to 3A@12VDC*.  
1. Connect the auxiliary device to the auxiliary relay. The two auxiliary relay terminals are the  
left-most terminals on the terminal block as shown in the diagram below.  
2. Select which channels will trigger the auxiliary relay using the Auxiliary Relay DIP switch  
(SW8), located on the PCB as shown in the diagram below.  
3. If the switch is in the ON position, triggering the  
corresponding channel will activate the auxiliary relay.  
4. If the switch is in the OFF position, triggering the  
corresponding channel will not activate the auxiliary relay.  
Setting Auxiliary Relay Timer:  
*Note  
Included power supply will not  
support loads larger than 500mA.  
For larger loads, replace with  
appropriate DC power supply.  
1. Output time can be adjusted from 1 second to 10 minutes  
using the auxiliary relay output time potentiometer.  
2. Turning the potentiometer clockwise will increase the output time.  
3. Turning the potentiometer counterclockwise will decrease the output time.

Lamp  
1. A photobeam sensor installed on a driveway (E-960-D90Q or similar) is connected to an  
RF wired transmitter (SK-919TDWS-BU or similar). When the photobeam sensor is  
triggered, the transmitter sends a signal to the SK-910RC4Q Central Receiver.  
2. Inside, an alarm, lamp, or other signaling device is connected to the channel’s relay output.  
When the intruder triggers the photobeam sensor, an alarm is triggered or the light turns on.  
3. Alternatively, a DVR (DR-1 series or similar) can be connected to an RF wired transmitter.  
When an event (such as motion detection) occurs on the DVR, the transmitter sends a signal  
to the SK-910RC4Q Central Receiver, alerting the user and activating the channel relay.  
4. In addition to connecting a signaling device to the channel relay output, an auxiliary device  
such as an LED strobe light (SL-1301 series or similar), can be powered by the SK-910RC4Q  
Central Receiver when a channel is activated.

Troubleshooting:  
The SK-910RC4Q will not read a  
transmitter it has already learned.  
Check that the transmitter is operating within the  
receiver’s range.  
Check number of transmitters learned. Learning more than  
15 will cause the first transmitter learned to be deleted.  
Check that there are transmitter codes stored on the  
channel by pressing that channel’s programming button  
once and counting the flashes.  
The SK-910RC4Q is not in the correct  
relay output mode.  
Programming modes change starting from the current  
mode. For example, press the programming button 3 times  
to go from Toggle Output to Timed Output. If necessary,  
please review Programming Channel Output on page 5.
