E-Key – Ultra Secure RF Remote Controls      

 

 

 

 

Versatile 433MHz remote control transmitters & receivers with AES Encryption & rolling-code security 
features. 
 
Receivers for standalone (relays) or for access control system integration (

Wiegand

 compliant outputs for use 

with E-Keys running Wiegand, HID, Mifare or other bit formats) 
 

 

 

 

 

 

 

 

 

 

Applications 

 

 

 

 

 

 

 

 

 

  Security access control systems or standalone 

  Remote keyless entry  

  Remote Garage door & gate operation  

  Car park barrier arms 

  Home automation and security 

  General & security lighting 

  Swimming pool controls (pumps, lighting) 

  Personal emergency alarming 

  Any other application requiring wireless remote control

 

 

Features 

 

 

 

 

 

  2 or 4 button E-Key in Classic styling 

  4 button E-Key in Metallic styling, rated IP65  

  128 bit AES encrypted data transmission guarantees security as all transmissions are immune from 

code grabbing and code scanning 

  16 bit rolling-code further ensures only legitimate E-Keys are accepted 

  Standard data-encryption key or your own unique data-encryption key 

  Transmission range over 100m without substantial barriers 

  Blue ‘transmitting’ LED on the E-Key for visual indication of any button press 

  E-Key battery life with normal use is estimated as more than the battery shelf life of 10 years 

  Up to 433 E-Keys may be added to each receiver unit 

  Access Control System integration receiver 

o

  Four Wiegand compliant data output channels 

o

  E-Keys are auto-added once seen by the receiver 

o

  The encryption key of the first E-Key is registered and all subsequent E-Keys must match that 

of the first E-Key seen by the receiver 

o

  E-Keys are supplied pre-programmed with your Wiegand/HID/Mifare/other bit format  

  Standalone relay output receiver 

o

  Four voltage-free SPDT relay output channels provide a universal interface to any equipment 

o

  Easy-add first E-Key with the ADD button on the receiver 

o

  Additional E-Keys added via the ADD button or remotely in unison with an existing E-Key 

o

  Versatile relay operation modes (pulse, Flip/Flop, time delay, hold, etc.)
