Disablement/Enablement Function
This function allows specified zones to be
disabled at certain times of day.
An example is shown opposite. The stated
period (19:30 to 21:00) is the ‘NOT effective’
phase and it ‘wraps around’ - this is admissable
in any time-of-day program. The effect is the
same as if the input were an input module
manually activated daily between the specified
times.
To use this function
You need one Control Matrix entry with TRUE
as the input and a time-of-day program and
the disablement as the output.
The TRUE option with time-of-day may also
be used for outputs other than DISABLE (e.g.
for activating a module output).
Note
: The minimum duration of a specified
time-of-day period is ten minutes,
therefore, it is not likely to be of use as
a ‘class change’.
However ...
Zones may be disabled or enabled by other
means (panel pushbuttons, an external AUX
input or with the global Cancel Disablement at
Set Time/after Timeout facility). The time-of-
day-driven setting will then be re-asserted:
a. By any subsequent time-of-day status
change (even one used for a completely
different purpose). In the example shown,
a sensor undergoes a time-of-day change
of sensitivity at 20:30.
b. At the beginning and end of the configured
period.
EN54-2: 9.1.2
Disablement and
re-enablement MUST be
a manual operation.
