Masking can activate mask outputs, depending on whether the zone is set or unset and
the Mask configuration options (see page 80). Also, masking may or may not inhibit users
from setting the affected ward, depending on whether the Mask Override or Mask Inhibit
configuration option is selected (page 80).
A masking zone, or a standard zone with a masking status, must remain active
for the duration of the Anti Mask timer (page 59) for a masking alert or masking
output to activate.
Occupancy
This zone type enables a warning message to be automatically displayed at the keypad
if a user sets a ward that may still be occupied by other people.
A zone of this type is normally connected to an "occupancy" output (open/closed
contact) of an access-control system. When the contact is opened, this indicates that
the ward(s) associated with the zone are occupied. When the contact is closed, this
indicates that the wards are not occupied.
If a ward is occupied when a user attempts to sets the ward, a warning message is
displayed, but the user can override the message and continue with the setting
procedure.
Security
A Security zone type is monitored at all times and can be used to lock-out all keypads in
wards associated with the zone (page 35). The keypads cannot be used while the zone
contacts are in the triggered position (i.e. by default open).
If a non-latching switch is used, set the Non Latching zone attribute (page 32) to YES. The
first operation of the switch disables the keypads, and the next enables the keypads.
Note: The control unit does not lock out the keypad during entry times, regardless of the state of
the security zone input.
Step 3 – Select Attributes
Each zone can have one or more of the following attributes to alter its operation.
1– Access
Normal Alm zones programmed with this attribute are automatically isolated during the
entry or exit procedure to allow a "walk through" route to access the keypad or to exit.
The Entry zone type (page 27) performs the same function.
You may also want to apply this attribute to a Final Exit zone type to prevent the "zone
triggered" tone when exiting.
2 – Double Knock
Zones programmed with this attribute will cause an alarm only if the zone is triggered a
specified number of times within the Double Knock period (page 59), or the zone
remains active for the whole of the Double Knock period.
The number of times the zone needs to be triggered is determined by the Double Knocks
counter (page 61).
3 – Soak Test
This attribute is useful if you want to place a zone under test. The attribute enables you to
find out whether activations of the zone have occurred, without the activations causing
alarms.
