Introduction:
The SK-910RBQ series of wireless receivers meet the growing demand for receivers with multiple, independently-controlled output functions. These RF receivers are compatible with both code hopping and fixed code transmitters (see pg. 4 for a note about compatible transmitters and visit www.seco-larm.com for a full list). The receivers can be used to remotely control a variety of home automation devices such as garage door openers, lights, motorized gates, lifts, or other devices.
Installation Notes:
- Mount the receiver out of sight in a location where it is not exposed to weather or moisture, and where it is not surrounded by Metal will block the RF signal, resulting in a reduced range.
- For best range, pull the antenna wire as long and straight as If the receiver receives interference from local RF activity (e.g., an airport or military base), the antenna wire can be folded.
IMPORTANT: DO NOT CUT THE ANTENNA WIRE.

Each receiver channel can learn the codes of up to 15 different transmitters on a first-in, first-out basis. Below is the procedure for code learning a new transmitter button.
- Press the channel mode switch of the desired channel for 3 seconds or The channel’s LED will start to flash quickly to indicate that it is in learning mode.
- While the LED is flashing, press the button of the transmitter to be learned one The receiver’s channel indicator LED will flash once to indicate the transmitter button has been successfully learned. After the button has been learned, the receiver will automatically exit learning mode. To learn further codes, repeat step 1 to re-enter learning mode.
NOTES:
- The channel mode switch(es) can be found at the rear of the receiver’s
- The channel’s indicator LED will flash a maximum of 15 If no transmitter button is pressed during this time, the receiver will exit code learning mode, and the LED will turn off.
- If the code being learned has already been learned, the channel indicator LED will turn steady ON and then start flashing The code will not be learned a second time.
One channel can learn the codes of a maximum of 15 transmitter buttons. If you attempt to learn a sixteenth transmitter code, the earliest code learned will be deleted and the new code will be learned
Clear Channel Memory:
To clear all codes from a channel’s memory, press the channel’s mode switch for 3 seconds or more until the channel indicator LED flashes. Release, and then press the switch again for 3 seconds or more until the LED stops flashing. The LED will then flash twice to indicate that all codes associated with that channel have been deleted.
Display Channel Memory:
To see how many codes have been learned by a channel, press that channel’s mode switch once. The number of codes stored in the channel’s memory is equal to the number of times the channel indicator LED flashes.
Programming Channel Relay Output Function:
Each channel relay can be programmed for one of five output functions. SK-910RB2Q only: Each channel can be independently programmed to operate in a different function, depending on the user’s application. The five functions are:
- 4-Second Timed Output (default) – When the transmitter button is pressed, the relay will turn ON for 4
- Toggle Output – Works much like a toggle switch to turn a device ON & OFF Press the transmitter button once, and the relay turns ON. Press the transmitter button again, and the relay turns OFF.
- Latch Output – Press the transmitter button once, and the relay turns ON and stays The channel relay will remain ON regardless of whether a compatible transmitter button is pressed again or not. To turn the relay OFF, press the channel’s mode switch on the receiver once to reset.
- Validity Output – The channel will turn the relay ON for as long as the transmitter button is
Note: Due to possible interference or drops in transmitter battery power while the transmitter button is continuously pressed (even for short periods of time), the receiver may lose the transmitter’s signal and turn the relay OFF.
- 1-Second Timed Output – When the transmitter button is pressed, the relay will turn ON for 1
Selecting the relay output function:
- Hold down the channel function switch for 3 or more The channel’s LED will flash a number of times equal to the output mode that it is in.
- To change a channel’s function, press the channel’s function Each press moves to the next function in the sequence as shown in the diagram to the right.
- After changing functions, count the number of times the channel LED flashes to verify the channel is set to the correct function.
- To exit function programming, hold the appropriate
- function switch for 3 seconds, or wait 15 seconds.

Overview:
(PC board shown. Remove the front cover of the receiver to access the function switch(es) and terminal block.)
Channel Mode Switch Operation (One per Channel):
| Learn mode | Press and hold the channel mode switch for three seconds or more. |
| Clear memory | Press and hold the channel mode switch for three seconds or more, then when the LED starts
flashing, press again for three seconds to delete all previously learned codes. |
| Reset latched output | If the channel was programmed for latch output, once the relay is turned ON with a transmitter
button, press the channel mode switch of that channel once to turn the relay OFF. |
| Memory Display | Press and release the channel mode switch to show the number of codes stored. The LED will flash a number of times corresponding to the number of codes stored. |
LED Indication (One per Channel):
| Steady ON | Receiving signal from a transmitter button during normal operation, or indicates a transmitter button’s code already exists in the receiver’s memory during code learning. |
| Fast flash | Receiver is in code-learning mode or channel memory display mode, or during the programming channel output mode. |
| One flash | A transmitter button code was learned, or receiver channel is in 4-second timed output mode. |
| Two flashes | All previously learned transmitter buttons were deleted, or receiver channel is in toggle output mode. |
| Three flashes | Receiver channel is in latched output mode. |
| Four flashes | Receiver channel is in validity output mode. |
| Five flashes | Receiver channel is in 1-second timed output mode. |
| 0~15 flashes | During normal operation, pressing a channel mode switch will cause the channel indicator LED to flash. Number of flashes indicates the number of transmitter buttons currently stored. |
Extended Range Antenna (Optional):
The SECO-LARM SK-91ERSD/ SK-93ERSD significantly extends RF receiver range with existing remotes. It comes with a 9ft (2.7m) cable that easily plugs into the 3-pin antenna port located on the RF receiver.
NOTES:
- Antenna range will vary greatly depending on the installation and operating
- To use an extended range antenna, the loop marked “LP3” on the receiver PC board must be
- To protect the antenna components and the RF receiver circuits, please turn off power to the RF receiver before cutting the loop “LP3” on the PC board and before connecting or disconnecting an external
- The SK-9xERSD is not For outdoor use, seal the case seams and connections with silicone sealant.
