4.3.3.2 Mask Alarms (Not Applicable to Dennard 2040)
Alarm responses can be modified, depending on when they are activated. Selecting this facility will
bring up the following screen:

Entering a '1' under a day of the week means that the alarms will be masked – i.e. they will not
cause a response from the dome – on that day. Similarly, a '1' under the Holiday means that the
alarm is masked on specified holidays (note that the setting for a holiday will override the setting for
a day of the week). The mask will operate throughout the days selected unless a mask on and off
time are entered. This is achieved through numerical entry of the time using the 24hr clock. The
mask temporarily disables all connected alarms.
For example, if motion sensors have been connected into the dome but are only required to
operate outside of normal working hours they can be masked by entering the code
'1111100008301800'. This masks the alarms on Mon – Fri between 08.30 a.m and 6 p.m. Outside
these times, and at the weekends and on holidays, the dome will respond to the alarms as desired.
To add complete flexibility, up to ten levels of configuration are available, indicated by the 'Item
number' on the screen. As each entry is accepted the number increments until the full action is
saved. Secondary levels allow different masking times to be selected on different days. In the
example above, it may be that the building closes early on Friday. To achieve the different times,
the first code (item) would be modified to '1111000008301800' and a second item code entered as
'0000100008301400'. Now, the first mask only applies from Monday to Thursday while the second
level masks the alarms on Fridays, between 8.30 a.m. and 2 p.m. More complex masks can be built
up using the same logic for more variations.
4.3.3.3 Select Holidays (Not Applicable to Dennard 2040)
Up to 15 days can be programmed in as holidays, to cover periods such as Christmas or Bank
Holidays, when the alarm action may require modification. When the option is selected the following
screen is displayed:
