Overview

The Ajax KeyPad Plus Jeweller is a wireless touch keypad that arms and disarms an Ajax alarm with a code or with a tap of an Ajax Pass card or Tag key fob. The cards and fobs use encrypted DESFire EV1 and EV2 technology, so they cannot be copied with a simple cloner. It suits homes, shops and offices where staff or family prefer to tap a card rather than remember a code.

Is it right for you?

  • It suits an indoor entrance in a home, shop or office on an Ajax system where you want cards or fobs as well as codes.
  • It is indoor only (-10 to 40 °C, up to 75% humidity).
  • If you only need codes, the KeyPad Jeweller does that; if you want a screen with event history and phone authorisation, look at the KeyPad TouchScreen.
  • It works with Hub (4G), Hub Plus, Hub 2, Hub 2 (4G), Hub 2 Plus and the ReX and ReX 2 range extenders.

Key features

  • Three ways to control the system: codes, Pass cards and Tag key fobs. Cards and fobs do the same job and differ only in design.
  • DESFire EV1 and EV2 contactless access on ISO 14443 (13.56 MHz) with 128-bit encryption and copy protection.
  • Up to 200 personal codes and one keypad code, duress codes for each, and up to 99 codes for unregistered people, depending on the hub model.
  • Group security: enter the keypad code and a group ID to arm or disarm one area.
  • Function button for raising an alarm or muting interconnected fire detector alarms.
  • Code guessing protection locks the keypad for 3 to 180 minutes after more than 3 wrong codes within 1 minute.
  • Four AA batteries, pre-installed, with a calculated life of up to 3.5 years.
  • Jeweller two-way radio with encryption and frequency hopping, up to 1,700 m to the hub or range extender in open space; tamper alarm and communication loss detection after 36 s.

What else you need

An Ajax hub or range extender from the compatible list and the Ajax app. For contactless access you also need Ajax Pass cards or Tag key fobs for each user; codes work without them.

Installation

Mount it indoors on the SmartBracket mounting panel beside the door with the supplied installation kit. An Ajax installer can add it to the hub, enrol cards and fobs and set codes in the app.

Software and licences

Codes, cards, fobs, the function button and the lock time are managed in the Ajax app by an administrator or an Ajax PRO.

Before you buy

  • Indoor use only.
  • Order Pass cards or Tag fobs for each person who will tap rather than type.
  • Choose black or white; the keypad is 165 × 113 × 20 mm.
  • Code counts depend on the hub model.
