Contactless control without sacrificing consistency

KeyPad Plus combines design, modern encryption technology, and an enhanced user experience to provide the most straightforward and secure security management. Utilizing a Pass card or Tag key fob, you can arm and disarm Ajax, turn on Night Mode, and control individual partitions.

Highest level of data protection

KeyPad Plus uses DESFire® technology to identify users instantly and securely. It is the best-in-class contactless option for identifying a user through card or key fob.

Based on the international ISO 14443 standard, DESFire® combines robust 128-bit encryption and prevents copying.

No need to worry

The brand-new KeyPad Plus firmware maximises the performance of the built-in batteries. Even with frequent use of the contactless identification function, the keypad will last for 3.5 years without changing the batteries. With the card and key fob reader turned off, the battery life is extended to 4.5 years. KeyPad Plus will notify a monitoring station and users when the batteries need to be changed.

Security mode activated

Controlling the security status without an Ajax app is possible thanks to the KeyPad Plus' light and sound indication. The backlight's volume and brightness can be modified.

Intelligent security management system

Make use of scenes to transition your daily routine to Ajax. When the system is armed, it switches off the lights, the water and electrical appliances, and closes the roller shutters with a single touch of the KeyPad Plus.

Remote access control

Create individual passcodes to keep track of who disarms the system and when; a username is shown in the notification and event log. To manage the security of groups or the entire website, Pass or Tag can also be assigned to a specific user with set permissions. You may manage access rights in real time with an ajax application. Access might be restricted, extended, or immediately blocked.

adding people. swift and simple

Up to 200 Tags or Passes can be used with Ajax systems. You only need to provide a name for the device and specify access rights when adding new users; you do not need to establish Ajax accounts for them. This makes granting temporary workers or new hires access to the system easier.

Anti-sabotage mechanism on multiple levels


When the keypad is taken off of the mount, users and the central station are notified

When attempting to guess a passcode, blocking occurs.

The keypad is blocked, and an alert is set off when three consecutive incorrect passcodes are entered.


The device sounds an alarm whenever an attempt is made to utilise a key fob or invalid card.

polling cycles

In less than a minute1, the system detects a communication failure with the keypad.

1 With hub—detector polling period of 12 seconds.

Transmission of a silent alarm to a monitoring station

If attackers attempt to disable the system Duress codes allows you to mimic disarming through KeyPad Plus. The alarm signal is immediately transmitted to a central monitoring station, but it won't trigger the sirens, the app, or the keypad indications.

Deliveries of alarms are assured

To guarantee the continuous operation of all system components, we designed the Jeweller radio protocol. Time frames, authentication, and encryption are all used by the radio protocol to synchronise communication between linked devices and prevent forgery and hacking.

Easy to install

Use the Ajax app to set up your KeyPad Plus. There is no need to disassemble the enclosure or install batteries. Simply scanning a QR code allows you to add the device to the system. An installation engineer simply needs to test the device, add cards, and configure access permissions.
