) the blocking time could be increase to a theoretical unlimited value.
Of course this time will be then limited by the maximum line seizure time (see
also
Maximum line seizure time
).
We suggest you to find a value of the
maximum blocking time which should be below the maximum line seizure time
programmed.
If you use the keypad as a access control device you can limit the number of
attempts to input a wrong code. This feature is only useful if you are using also the
blocking time increase function. The maximum number of attempt will then limit
the maximum blocking time to a specific value. Also it is possible that if the
maximum number of attempt is reached a programmed telephone number (speed
dial code 99, see also
Speed call numbers
) is called automatically. As default this
feature is deactivated. The maximum number of attempt can be between 00
(deactivated) and 99. To program the maximum number of attempt follow this
procedure:
OK tone
{maximum number of attempts}
{
without or
with automatic telephone call}
OK tone
Values between
and
can be programmed. The value
will
deactivate this function.
Example:
You want that max. 3 attempts with wrong access codes can be made. After-
ward the unit will call automatically a programmed telephone number. Input:
OK tone
OK tone
The telephone number must be programmed with the speed dial code
(see
also
Speed call numbers
)
Please note!
The automatic line disconnection and new seizure with dial of a programmed
telephone number will work ONLY if the device has an EXTERNAL POWER
SUPPLY. If the device is powered only BY THE TELEPHONE LINE the feature is
NOT AVAILABLE.
