Unauthorized access auto-lock
If a wrong code is entered three times within 1 minute, the keypad will be locked
for the time speci ed in the settings. During this time, the hub will ignore all
codes and inform the users of the security system and the CMS about an
attempt to guess the code.
The keypad will automatically unlock after the lock time de ned in the settings
expires. However, user or PRO with administrator rights can unlock the keypad
through the Ajax app.
Two-stage arming
KeyPad participates in arming in two stages. When this feature is enabled, the
system will only arm after being re-armed with SpaceControl or after a second-
stage detector is restored (for example, by closing the front door on which
DoorProtect is installed).

Jeweller data transfer protocol
The keypad uses the Jeweller radio protocol to transmit events and alarms. This
is a two-way wireless data transfer protocol that provides fast and reliable
communication between the hub and the connected devices.
Jeweller supports block encryption with a oating key and authentication of
devices at each communication session to prevent sabotage and device
spoo ng. The protocol involves regular polling of devices by the hub at intervals
of 12 to 300 seconds (set in the Ajax app) to monitor communication with all
devices and display their statuses in the Ajax apps.
