Wiring a Fault/Masking Zone: 3 Resistor Method.
The detector must signal masking by closing both the Alarm and Fault contacts together.
(If the detector closes the Fault contact only, then the control unit reports this as a detector
fault.)
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.
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 programmed as 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 then 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 programmed as General Fault, and generates an Alert on
the keypads.
On a Security Grade 3 system the Installer must reset the Alert.
On a Security Grade 2 system the ability to reset the alert is
governed by the System Options - User Reset - System Tampers
option, see page 89.
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).
When the system is set:
Detector output
Response
Mask
(Alarm open,
Fault open,
resistance = 9k1)
The control unit treats a masking event as an alarm condition
(and also activates any output programmed as 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 88.
