When masking is enabled, the alarm response depends on whether the system is set or
unset, and which resistance range the detector is signalling with.
Off
The system hides the Masking zone attribute, and the
Mask Override
option (see
below). The control unit treats masking signals from FSL detectors as alarms or
tampers depending on the resistance.
On
The system makes available the Masking zone attribute and
Mask Override
option.
Alarm response when the system is unset
Detector output
Response
Mask
(Alarm open,
Fault open,
resistance = 9k1)
The control unit treats a masking event as a fault, activates any
outputs of type General Fault or Masking, and generates an Alert
on the keypads.
A user can reset the system once the masking is cleared.
If user reset is disabled, the installer can reset this fault remotely.
Fault
(Alarm closed,
Fault open,
resistance = 4k4)
The control unit treats this condition as a fault, activates any
outputs of type General Fault, and generates an Alert on the
keypads.
The ability to reset the alert is governed by the
System Options
–
User Reset
– System Tampers
option, see page 85.
Note:
There is a delay of about three seconds before the control
unit starts the alert at the keypad. This delay is intentional, and is
designed to confirm that the fault is a true fault, and not the first
stage in the detector reporting a masking event. Two or more
detector fault events occurring within three seconds of each other
may prolong the delay up to 10 seconds (but no longer).

Response
Mask
(Alarm open,
Fault open,
resistance = 9k1)
The control unit treats a masking event as an alarm condition
(and also activates any output of type Masking). This will signal
an unconfirmed alarm or will confirm an outstanding unconfirmed
alarm. The unconfirmed and confirmed events must be from
different detectors.
The ability to reset the system after the alarm is governed by the
System Options
– User Reset – Zone Alarms
option, see page
Note that the user can also reset this alarm provided they do so
within the abort time.
Fault
Alarm closed,
Fault open,
resistance = 4k4)
The control unit treats this condition as a fault and activates any
outputs of type General Fault. When a user unsets the
partition/system, the control unit generates an alert on the
keypads.
The ability to reset the alert is governed by the
System Options -
User Reset
– System Tampers
option, see page 85.
