Use To Control The Garage Door, House Lights, Alarm Control Panel & More!

The Seco-Larm 4 Channel Fixed Code Receiver controls home automation functions, garage doors, alarm panels, etc., from up to 500 ft. The Fixed Code Receiver features 4 RF outputs that are independently programmable and a Mode switch for easy programming. This Receiver is compatible with all SECO-LARM transmitters. It also features 4 LEDs, one per channel to indicate RF reception, learn mode, transmitter cleared and output type.

Building A Secure Future Since 1971

SECO-LARM started as a developer of lighting devices in 1971. However, the company foresaw the need for reliable yet affordable security products, and over next few years established SECO-LARM as a leading multinational OEM and private label manufacturer of equipment for some of the best-known companies in the security business.


  • Use to control home automation functions, garage door openers, house lights, alarm control panels, motorized gates, lifts or other devices by remote control.
  • 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:
    • Timed Momentary (1, 2, 3, 4, 5, 10, 30, 60 sec.)
    • Toggle (On/Off)
    • Latch (Output stays on until manually reset)
    • 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: 43/8" x 55/16" x 11/8" (111 x 135 x 28mm).
  • 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:
  • Hi-Q SELECTIVITY and a CODING IC for rejecting unwanted RF signals.
  • HIGHER SENSITIVITY for greater operating distances.
  • UNSURPASSED ANTENNA MATCHING CAPABILITIES so the receiver is less affected by how and where mounted.
  • GREATER TUNING STABILITY so the receiver’s frequency remains unaffected by shock and vibration.
