SECO-LARM SK-910RAQ Series Miniature RF Receivers

SECO-LARM SK-910RAQ Enforcer Rf Receivers

SK-910RAQ SERIES Miniature RF Receivers

Up to 500 ft. range
Operate on 11-24VAC/DC1
Code learning
FCC compliant
Fixed code or CODEBUMPTM code-hopping

Introduction

These mini RF receivers are compatible with both code hopping and fixed-code transmitters (see page 4 of this manual for a list of compatible transmitters). They can be used for a variety of applications, such as allowing the same transmitter to arm/disarm a vehicle alarm and open/close a garage door opener. The receivers come in one- or two-channel versions. Each channel can learn the codes of up to 15 different transmitter buttons on a first-in, first-out basis.

Installation Notes

Mount out of sight in a location where it is not surrounded by metal, and where it is not exposed to the weather or moisture. Metal will block the RF signal, resulting in a reduced range.
For best range, pull the antenna wire as straight and high as possible. If the receiver receives interference from local RF activity (eg., airport or military base), the antenna wire can be folded. DO NOT CUT THE ANTENNA WIRE.

All models work on 11-24VAC/DC, except for the low voltage versions.

Learning a New Button Code (channel 1)

Press the mode switch which is located at the top of the receiver case for three seconds. The green LED will start to flash quickly.
While the green LED is flashing quickly, press a button on a compatible transmitter. The green LED will flash once and then turn off to show that button was learned.
Repeat steps 1 and 2 to learn more buttons into channel 1.

NOTE — The green LED will flash a maximum of 15 seconds. If no transmitter button is pressed during this time, the receiver will exit the code-learning mode, and the green LED will turn off

Learning a New Button Code (channel 2, SK-910RAV2Q only)

The procedure is the same as for channel 1, except mode switch #2 (black switch) initiates the code-learning process, and the red LED shows status. For two channel receivers, red color push-button represent mode switch #1 and black color push-button represent mode switch #2 .

Note Regarding Code Learning

The receiver will only learn the code of a particular button once. Once a button’s code is learned, if you try to codelearn that button again, whether it is for the same channel or not, the receiver will remain in the code learning mode.
The LED will turn steady ON (1-sec.) to show the code is already in memory.
Each channel can learn the codes of a maximum of 15 transmitter buttons. If you attempt to learn a sixteenth button, the earliest code learned will be deleted and replaced by the new code (first-in, first out).
To clear all codes — To clear all codes in the channel’s memory, press the appropriate mode switch (#1 or #2) for three seconds. When the LED starts flashing, press that switch again for three seconds. The LED flashes twice to indicate that all codes associated with that channel are now deleted.

Programming Output Modes (see table 1)

4-second momentary| Press the transmitter button once. The output turns on for 4 seconds, and then turns off. (This is the DEFAULT mode)
---|---
1-second momentary| Press the transmitter button once. The output turns on for 1 second, and then turns off.
Toggle| Press the transmitter button once, and the output turns on. Press a compatible transmitter button again, and the output turns off.
Validity| The relay turns on for as long as the transmitter button is pressed.

Mode Switch Operation (one per channel)

Learn mode| Press and hold the switch for three seconds. The appropriate LED will flash quickly to show that it is ready to learn a transmitter code.
---|---
Clear memory| Press three seconds, then when the appropriate LED starts flashing, press again for three seconds to delete all previously learned codes. The LED will flash twice to confirm codes deleted.
Memory Display| Press and immediately release the mode switch to show number of codes stored. The appropriate LED will flash a number of times to correspond to the number of codes stored.

LED Indication (one per channel)

Steady on| Senses signal from a transmitter button whose code was already learned.
---|---
Fast flash| In the code-learning mode.
One flash| A transmitter button code was learned.
Two flashes| All previously learned transmitter button codes were deleted.

LED Indication

Table 1: To program outputs, open case and find the jumpers marked LP1, LP2, LP3, and LP4 . Cut these jumpers, if needed, as follows:

| 4-SEC. MOMENTARY| 1-SEC. MOMENTARY| TOGGLE| VALIDITY
---|---|---|---|---
LP1| UNCUT| UNCUT| CUT| CUT
LP2| UNCUT| CUT| UNCUT| CUT
LP3| CUT LP3 TO USE EXTERNAL ANTENNA
LP4| CUT LP4 FOR 16~24VAC/DC POWER INPUT (for SK-910RAQ only)

NOTE — For the SK-910RAV2Q 2-channel model, the mode of both outputs is the same. In other words, you cannot have 4-second momentary output for channel 1 and a validity output for channel 2

Typical Applications:

Positive or negative output

Typical Applications

12VDC receiver power driving a 12VDC appliance

Typical Applications

12VDC receiver power input, 24VAC output driving a motor

Typical Applications

For SK-910RAVQ /SK-910RAV-4Q and SK-910RAV2Q / SK-910RAV2-4Q

Typical Applications

Extended Range Antenna for SK-910RAQ only

The optional SK-91ERSD extends the RF receiver range to up to 1,200’ (open air) with existing remotes.
The antenna comes with a 9’ cable which easily plugs into the 3-pin antenna port located on the RF receiver motherboard (see the illustration above).

IMPORTANT: If an extended range antenna is used with the SK-910RAQ, the receiver PC board loop marked “LP3” must be cut.

CODEBUMPTM
With SECO-LARM’s
CODEBUMP, so-called codegrabbers and scanners are rendered obsolete because the RF code changes every time the transmitter button is pressed. In addition, with over 18 quintillion (1.8 x 1019) codes, the chances of ever repeating a code are virtually non-existent.
SECO-LARM’s CODEBUMP transmitters and receivers are perfect for controlling garage and gate openers, car and home alarms, plus much more.
