SK-917T4J 4-Button CODEBUMP™ Anti-Codegrabbing RF Transmitter
  • Attractive - Like no other remotes on the market today.
  • Ultra Thin - Just 5/16" (8mm). Fits easily in any pocket.
  • Extreme Durability - Rubber buttons eliminate damage caused by electrostatic discharge and helps make transmitter water resistant. Gold-plated battery clips and contact points extend the life of the transmitter.
  • Magic LED - Only appears when buttons are pressed.
  • Frequency 315 MHz. Variable capacitance controlled.
  • Operates up to 500 feet (150 meters).
  • 18 quintillion possible codes (SK-917T4J), plus RF anti-scan protection.
  • Use with SK-910R4 as well as SK-910R and SK-910R2.
  • Includes 12VDC alkaline battery with handsome key chain ring.
    Private label available. Contact SECO-LARM for details.
SK-910R4 Four-Channel CODEBUMP™ Code-Hopping RF Receiver (Shunt/Momentary Operation)
Controls home automation functions, garage doors, alarm panels, etc., from up to 500 ft. Similar to SK-910R & SK-910R2 except with 4 outputs, independently programmable. Compatible with all SECO-LARM transmitters. Mode switch for easy programming. 4 LEDs, one per channel, indicate RF reception, learn mode, transmitter cleared, output type. Add optional plug-in extended range antenna: SK-91ERSD or SK-91ERSW.
  • Use to control home automation functions, garage door openers, house lights, alarm control panels, motorized gates, lifts or other devices by remote control.
  • Patented CODEBUMP™ anti-codegrabbing technology (requires use of CODEBUMP transmitter).
  • Uses either fixed code (SK-919TD2A-U, SK-919TD1S-U, SK-919T4J, SK-919T1H, SK-919T2H, or SK-919T4H) or code hopping (SK-917T2A-U, or SK-917T4J) transmitters with up to 500 ft. range using standard antenna.
  • External extended range antenna optional. Plugs directly into receiver PC Board. If SECO-LARM SK-91ERSD (Dipole Antenna) is used, range will be up to 1200 feet. If the SECO-LARM SK-91ERSW (Monopole Antenna) is used, range will be up to 800 feet.
  • Mode switch for easy transmitter learning.
  • Easily Code-learns up to 15 remotes per channel.
  • Stores codes safely in EEPROM for up to one year in case of power loss.
  • Four Form-C Dry Relay Contact (N.O./N.C./Common) Outputs. Each output rated 10 Amps at 24 VDC.
  • 4 Separate Channels / 4 Output Modes Each:
  • a. Timed Momentary (1, 2, 3, 4, 5, 10, 30, 60 sec.)
  • b. Toggle (On/Off)
  • c. Latch (Output stays on until manually reset)
  • d. Continuous or Validity (Output for as long as signal is received)
  • All outputs are independently controlled. (i.e. Channel 1 can be toggle, Channel 2 can be one second momentary, etc.)
  • Note: If the timed momentary output is chosen for any channel, there will be only one time available for all channels. In other words, if a one-second output time is selected for one channel, then all other timed momentary outputs will be one second.
    Size: 5.31" x 4.33" x 1.1" (135 x 110 x 28 mm)
    • Four LEDs (One LED for each channel) to indicate RF reception, learn mode entered, transmitted learned, memory cleared.
    • Use to control the garage door, house lights, alarm control panel, or other functions that require momentary or shunt operation.
    • In addition, these revolutionary receivers have:
      1. Hi-Q SELECTIVITY and a CODING IC for rejecting unwanted RF signals.
      2. HIGHER SENSITIVITY for greater operating distances.
      3. UNSURPASSED ANTENNA MATCHING CAPABILITIES so the receiver is less affected by how and where mounted.
      4. GREATER TUNING STABILITY so the receiver's frequency remains unaffected by shock and vibration.
    CODEBUMP™ Technology
    Be prepared for today's thieves with SECO-LARM's patented CODEBUMP technology. With CODEBUMP, so-called "code-grabbers" 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.
