KeyPad Plus

Uses GSM or Ethernet to send alarms to the Central Monitoring Station and the owner
Sends a notification in case of electrical power loss and operates for up to 15 hours from battery backup
Checks the functionality of detectors at least every 12 seconds

Contactless control without reliability compromises

KeyPad Plus is a combination of design, advanced encryption technology, and elaborated user experience for the most straightforward and protected security management. Arm and disarm Ajax, activate Night Mode and manage specific groups with a Pass card or Tag1 key fob.

Top-tier data protection

To identify users quickly and securely, KeyPad Plus features the DESFire® technology. It is the best-in-class contactless solution to identify a user by card or key fob.

DESFire® is based on the ISO 14443 international standard and combines comprehensive 128-bit encryption and copy protection. This technology is also used in transportation systems of European capitals and access systems at NASA.

Outstanding autonomy

The all-new KeyPad Plus firmware gets the most out of the pre-installed batteries. Even with daily use of the contactless identification function, the keypad will work for 3.5 years without replacing batteries. And with the card and key fob reader disabled, the battery life reaches 4.5 years. KeyPad Plus will warn a monitoring station and users in advance about the need to replace the batteries.

Adding users. Fast and easy.

Ajax systems support up to 200 Tags or Passes2. When adding them, you do not need to create Ajax accounts for new users, you just need to name a device and define access permissions. This makes it easier to delegate access to the system control to temporary employees or incoming staff.

Security mode indication

Light and sound indication of KeyPad Plus allows controlling the security status without the Ajax app. The volume and brightness of the backlight is adjustable.



Blocking when guessing a passcode

Polling intervals

Silent alram transmission to a monitoring station

If attackers force to disarm the system, Duress code allows you to simulate disarming via KeyPad Plus. 

The user is not disclosed by sirens, the app and the keypad indication, but the alarm signal is instantly transmitted to a central monitoring station4.
