Protect Your Keypad Settings From Tampering

Grant access to your home, office, or other sensitive area by keypad code or proximity card, without the risk of unauthorized entry by tampering, with the Seco-Larm Enforcer Split Series Keypad with Proximity Card Reader. While the keypad/proximity reader itself installs outside the door, its computing controller installs inside (connected to the keypad by wiring through the wall), thereby preventing potential intruders from tampering with the controller. All settings are safely protected indoors. And the keypad remains easy to use. To unlock your door, simply enter your code or wave an authorized proximity card/tag (sold separately) within 1-1/2 inches of the keypad.

  • Operates up to three different entryways (doors, gates, etc.)
  • Supports 1,000+ user codes and/or proximity cards/tags
  • Compatible with Seco-Larm 125kHz proximity cards/tags
  • Keypad illuminates when a button is pressed for easy nighttime use
  • Controller's built-in door chime announces that access has been granted
  • Simple 3-wire connection between keypad and controller

Installation Details

The keypad unit surface-mounts to a wall with the included single-gang back box and screws. The controller surface-mounts on the other side of the wall with the included screws, and uses a simple 3-wire connection through the wall to communicate with the keypad.

Settings are programmed directly through keypad, so no external programmer is needed. EEPROM Memory protects programmed information in case of power loss.
