A holiday scheme can contain up to 1 turning of the year. When a holiday scheme is programmed from
25/12/2001 to 02/01/2003, this will not be accepted. The control panel ignores the value 000000 - 000000.
The same dates can be used in several holiday schemes. It also possible to program the same start and end
date, e.g. 010102-010102, which will mean that the control panel only ignores the RTC on the first of
January 2002.
Up to 5 holiday schemes can be programmed for each timer switch. Using the <

several holiday schemes can be shown.
Prealarm function
When the RTC is used, outputs can be programmed to give a signal before the automatic arming, to warn
any people who are still inside the premises. These outputs can be programmed in screen 6 of the
programming. All outputs of the I/O, input + 8 OC and control panel, except for the control panel’s speaker
output (output 9), can be used to activate the prealarm signal. It is possible to program several outputs for
each RTC module, so that the prealarm signal can be given at several places within the premises.
Attention:
Control of the speaker output of the I/O modules can only be done with AlphaVision NG I/O
modules with software version 4.0 or higher, and with AlphaVision 96 I/O modules with software version
3.2 or higher.
The arm and disarm times are programmed using function 23. When programmed, the first signal is given
for three seconds at the programmed arm time. Depending on the programming in screen 8 “Minutes
prealarm RTC”, the next signal is given each following minute, for up to the next 9 minutes. So, if you have
programmed the number of minutes to 5 minutes, the first prealarm signal is given at the programmed arm
time, the next signal is given after one minute, the second signal after 2 minutes, the third after 3 minutes,
the fourth after 4 minutes and 5 minutes past the programmed arm time, the control panel will arm itself.
This means that, when using the prealarm function, the programmed arm time is not the actual arm time, but
that the actual arm time depends on the prealarm programming.
When the automatic arming is delayed with the overtime function, the prealarm function will start at the end
of the overtime period.
Important notes on using the automatic timer switch
When using the automatic timer switch, there are some limitations and risks to keep in mind. When there is
only one section programmed to the timer switch, there will probably be few problems, when there are
programmed several sections to a timer switch, things get more complicated.
Suppose that sections A, B and C are programmed to RTC 1. In this case the followings things have to be
kept in mind:
•
When a timer switch is programmed to arm and disarm sections A, B and C, holiday schemes and
the overtime function can influence the arming and disarming. When a user programs an overtime
for section A, this will affect sections B and C as well, for these are also programmed to timer
switch 1.
•
When one or more zones are open when the timer switch attempts to arm the system, the control
panel will try to bypass these zones and arm the system with the open zones bypassed. If one of
these zones cannot be bypassed due to the programming in the control panel, the control panel will
not arm and all sections programmed to timer switch 1 will remain disarmed.
F26# Program RTC Correction factor
In case the internal clock of the AlphaVision NG control panel deviates, a correction factor can be applied.
This correction factor will lengthen or shorten the last minute of every day with a few seconds. To apply a
correction factor, execute function 26.
