Operating Principle
KeyPad is a stationary control device located indoors. Its functions include
arming/disarming the system with a numerical combination (or just by pressing
the button), activating Night Mode, indicating the security mode, blocking when
someone tries to guess the passcode and raising the silent alarm when
someone forces the user to disarm the system.
KeyPad indicates the state of communication with the hub and system
malfunctions. Buttons are highlighted once the user touches the keyboard so
you can enter the passcode without external lighting. KeyPad also uses a beeper
sound for indication.
To activate KeyPad, touch the keyboard: the backlight will switch on, and the
beeper sound will indicate that KeyPad has woken up.
If the battery is low, the backlight switches on at a minimum level, regardless of
the settings.
If you do not touch the keyboard for 4 seconds, KeyPad dims the backlight, and
after another 12 seconds, the device switches to the sleep mode.
When switching to sleep mode, KeyPad clears the entered commands!
KeyPad supports passcodes of 4-6 digits. The entered passcode is sent to the
hub after pressing the button: (arm), (disarm) or (Night mode).
Incorrect commands can be reset with the button (Reset).
When incorrect passcode is entered three times during 30 minutes, KeyPad
locks for the time preset by the administrator user. Once KeyPad is locked, the
hub ignores any commands, simultaneously notifying the security system users
of the attempt to guess the passcode. The administrator user can unlock
KeyPad in the app. When the pre-set time is up, KeyPad unlocks automatically.
