AJ-42816

The keypad that also reads credentials. Alongside up to 200 personal codes it accepts Pass cards and Tag key fobs using encrypted DESFire EV1 and EV2, so users can present a credential instead of remembering a code.

Built for the installer

Encryption is the point of difference. DESFire EV1 and EV2 credentials use Triple DES and 128-bit AES hardware encryption, which means a credential cannot be cloned by holding a reader near someone's pocket the way a 125 kHz prox card can. On a commercial site that matters.

Everything from the standard KeyPad carries over: duress codes per user, up to 99 codes for unregistered people, group security management and protection against code guessing. Cards and fobs are functionally identical and differ only in form.

Key features

  • Reads encrypted DESFire EV1 and EV2 credentials that cannot be trivially cloned
  • Codes and credentials on one device, so users choose what suits them
  • Duress codes per user disarm normally while silently signalling
  • Up to 99 codes for unregistered people such as cleaners and contractors
  • Group security management for sites divided into areas

What is the difference between Pass and Tag?
Function is identical. Pass is a contactless card and Tag is a key fob, so the choice is about what the user prefers to carry. Both use encrypted DESFire.
Are the credentials secure against cloning?
They use DESFire EV1 and EV2 with Triple DES and 128-bit AES hardware encryption, which is substantially harder to clone than a 125 kHz proximity card.
Does it still support codes as well as credentials?
Yes. Up to 200 personal codes plus duress codes and codes for unregistered people, exactly as the standard KeyPad, with credentials as an additional method.
Does this device need an Ajax hub?
Yes. All Jeweller devices report to an Ajax hub or a range extender. The device cannot operate standalone and does not connect to a third-party panel directly.
What does the 9NA region code mean?
It is the North America model, operating on the 905.0-926.5 MHz Jeweller band certified to UL/ULC standards. European models on 868 MHz are not interchangeable with it.
How quickly is a lost device detected?
Within 36 seconds. Jeweller polls each device continuously, so a jammed, removed or failed device is reported rather than quietly going offline.
