Introduction:
The SK-910R3Q and SK-910R4Q are wireless receivers that meet the growing demand for multi-channel receivers with
multiple and independently controlled output modes. RF receivers can be used to control a variety of home automation
devices such as garage door openers, lights, motorized gates, lifts, or other devices remotely.
These receivers are compatible with both fixed code and code hopping transmitters. Code hopping transmitters, such as
SECO-LARM CODEBUMP™ transmitters, change codes every time transmitter sends a signal for extra security. See page 4
of this manual for a list of compatible transmitters.
Installation Notes:
1. Mount the receiver out of sight in a location where it is not exposed to the weather or moisture, and where it is not
surrounded by metal. Metal will block the RF signal, resulting in a reduced range.
2. For best range, pull the antenna wire as long and straight as possible. If the receiver receives interference from local RF
activity (e.g., an airport or military base), the antenna wire can be folded. DO NOT CUT THE ANTENNA WIRE.

Transmitter Programming Button Operation (One per Channel):
Learn mode
Press and hold the transmitter programming button for three seconds or more.
Press and hold the transmitter programming button for three seconds or more, then when the
LED starts flashing, press again for three seconds to delete all previously learned codes.
If this channel was programmed for latch output, once the relay is turned ON with a transmitter
button, press the transmitter programming button of that channel once to turn the relay OFF.
Press and release the transmitter programming button to show the number of codes stored. The
LED will flash a number of times corresponding to the number of codes stored.
Clear memory
Reset latched output
Memory display
LED Indication (One per Channel):
Senses signal from a transmitter button in normal operation, or indicates a transmitter button’s
code already exists in the receiver’s memory during code learning.
Steady ON
In the code-learning mode or channel memory display mode, or during the programming channel
output mode.
A transmitter button code was learned, or the relay is in timed output mode.
All previously learned transmitter buttons were deleted, or the relay is in toggle

Extended Range Antenna (Optional):
Extends RF receiver range up to 1,000ft (304m) (open air) with
existing remotes.
SK-91ERSD
Comes with a 9ft cable that easily plugs into the 3-pin antenna port
located on the RF receiver.
NOTE:
If an extended range antenna is used, the “LP3” on the receiver PC
board must be cut.
Actual antenna range will vary greatly depending on the operating
environment.
