whole fourteen days then after midnight on the 14th day, the control unit returns the
zone to normal use.
If the zone is activated during those 14 days while the system is set, the control unit
logs the event as a "Soak Fail Znnn Alm" (nnn is the zone number, see page 26)
without sounding any sirens or starting communications. The control unit also lights
the red LEDs around the navigation key on the keypad to alert the user when they
unset the system. An installer must key in their access code to reset the alert.
During setting, the keypad displays a brief message to inform the user that one or
more zones are in soak test.
Note: If there is an output configured as type Zone Follow for a zone under Soak
Test, the control unit will continue to operate the output if the soak test zone is
triggered. The output will operate whether the zone is set or unset.
Double Knock
Zones programmed with this attribute will cause an alarm only if the zone is EITHER
triggered, restored and triggered again within a five-minute period, or if the zone
remains active for 10 seconds.
Note: Double Knock does not comply with EN50131.
Part Set B
(Not visible in a partitioned system.) When a user sets part set B, the control unit sets
only those zones where the Part Set B attribute = "Yes". (See also "Part Set Exit
Mode" on page 72.)
Part Set C
(Not visible in a partitioned system.) When a user sets part set C, the control unit sets
only those zones where Part Set C attribute = "Yes".
Part Set D
(Not visible in a partitioned system.) When a user sets part set D, the control unit sets
only those zones where Part Set D attribute = "Yes".
Part Set
(Only visible in a partitioned system.) When a partition is Part Set, zones in that
partition with this attribute are set. Note that if a zone is in more than one partition, all
partitions have to be set or part set before this zone will be set.
Omittable
When a zone has this attribute, a user can omit it before setting the system.
If a user tries to set the system when a zone with this attribute is open (active) the
control unit alerts them and pauses the setting procedure. The user can acknowledge
the alert by pressing  and continue setting, providing the feature is enabled in
System Options – User Access – Quick Omit (see page 84).
Note: Take care when assigning Omittable to an Entry Route zone when Quick Omit
is enabled. There is a risk that the user may omit the Entry Route zone in error.
Force Set Omit
When this attribute is set to Yes, a user with a remote control can set the system
while the zone is open (active), providing the feature is enabled in System Options –
Force Set (see page 97).
Masking
Apply this attribute either if you have connected a detector that reports masking by
changing the resistance between its mask/fault contacts, or if you have connected
the masking/trouble contacts of a detector using the "3 resistor method" (see the
Detectors/Devices Menu
