Tamper as Tamper Only
This is available for only for UK control units and when
Confirmation Mode
is set to
BS8243. The purpose of the option is to ensure strict compliance with BS8243 when
reporting tampers to ARCs.
Enabled
When an unconfirmed tamper occurs, the control unit sends only “Tamper” to the
ARC and activates any output configured as type
Tamper (this follows Eaton’s
understanding that BS8243, Annex H.7.1 applies to all Grades).
Disabled
When an unconfirmed Tamper occurs,
the control unit sends “Tamper”, “General
Fault” and “Burg” to the ARC. In addition, it activates any outputs of type Tamper and
General Fault. (See also Jamming on page 73 and Supervision on page 72.)
Note:
This option does not comply with BS8243.
The behaviour of the Disabled setting is used when
Confirmation Mode
is Basic or
DD243.
Note:
If you are using Fast Format communications, please ensure that one channel is
allocated for tamper. If you do not do this, the control unit reports tamper as an
unconfirmed Burg to ensure the condition is notified.
Masking
This option allows you to control whether the system responds to masking or trouble
events from those detectors that are capable of reporting them, are connected correctly to
the system, and are programmed with the Masking attribute.
The detector must use the wiring as shown in Figure 2 on page 10.
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.
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.
The ability to reset the alert is governed by the
System Options
–
User Reset
– System Tampers
option, see page 62.
Note:
There is a delay of about three seconds before the control
unit starts the alert. 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
