Pin Warning

This option determines the number of days notification before the expiry date of any user codes programmed as PIN Change. During the notification period, the user is prompted to enter a new code on entry of the expiring PIN. The default period is 99 days, with a programmable range of 1 – 99. If a user does not assign a new code by the end of the PIN Warning period, then the code is erased on the next unsetting of the system.

Note: The PIN Warning ends on the last day of the month, the PIN expires on the first day of the following month.

On the first day of each year, the British Summer Time (BST) Start date is set to the last Sunday in March and the End date is set to the last Sunday in October.

The operation of the Summer option is as follows: At 01 : 00 hours

on the Start date, the system clock advances to 02 : 00 hours. At 02 : 00 hours on the End date, the system clock goes back to 01 : 00 hours .

Note:The time always changes with reference to GMT. For example, Italy which is + 1 hour would be:

Last Sunday in March - 02.00 to 03.00 Last Sunday in October - 03.00 to 02.00

The Start and End dates can be reprogrammed by authorised user codes. Press the A> key to modify the Start date or the <B key to select the End date. The new date must be a valid four digit number in the day month format (dd/mm).
