16.12 Appendix M: Zone Attributes
The Zone attributes on the SPC system determine the manner in which the
programmed zone types function.
Zone
Type
Description
Access
When the ‘Access’ attribute on a zone is set, then on opening that zone, an alarm will not be generated if
either the entry or exit timer is running. When the system is full set the Access attribute is not active and
opening the zone will initiate a full alarm. The ‘Access’ attribute is most often used for PIR sensors located
close to an entry/exit zone. It allows the user free movement within the access area while the entry or exit
timer is counting down.
The ‘Access’ attribute is only valid for Alarm zone types.
All connected devices (Bells - Internal & External, Buzzers, Strobe) are activated.
NOTE
An alarm zone with Access attribute can automatically be changed to an entry/exit zone in
Partset mode if the Partset Access Option is set.
Exclude A
If the ‘Exclude A’ attribute on a zone is set, then an alarm will not be generated by that zone opening while the
panel is in the Partset A mode. The ‘Exclude A’ attribute is valid for Alarm zone type and Entry/Exit zones only.
A FULL alarm is generated if a zone with the EXCLUDE A attribute is opened while the system is in FULLSET
or PARTSET B Mode (Bells - Internal & External, Strobe).
Exclude B
When the ‘Exclude B’ attribute is set, the zone opening will not generate an alarm while the panel is in the
Partset B mode. The ‘Exclude B’ attribute is valid for Alarm zone type and E/Exit zones only.
A FULL alarm is generated if a zone with the EXCLUDE B attribute is opened while the system is in FULLSET
or PARTSET A Mode (Bells - Internal & External, Strobe).
24 Hour
If a Zone is assigned the ‘24 Hour’ attribute, then it is active at all times and will cause a full alarm if opened in
any mode. This attribute can only be assigned to the ALARM zone type. Generates a FULL Alarm in UNSET,
SET and PARTSET modes.
NOTE
The 24 Hour attribute overrides the settings of any of the other attributes for a particular
alarm zone.
Local
When the ‘Local’ attribute is set, an alarm generated by a zone opening will not result in the external reporting
of the event. The ‘Local’ attribute is valid for Alarm, E/Exit, Fire, Fire Exit and Medic zone types.
Double
Knock
Use this attribute to deal with troublesome detectors. (i.e. some detectors may generate activation signals
spuriously, thereby inadvertently trigger alarms on the system).
If two armed double knock zones are triggered (or the same one activates twice) during the double knock
period, then an alarm is generated. Double knock time is set in seconds. Two open actions within that time
period will generate an alarm. All open double knock zones are logged when the system is armed.
Chime
When the ‘Chime’ attribute is set for a zone, any opening of the zone during the Unset mode will cause the
internal buzzers to activate for a short period (2 seconds approx.).
The Chime attribute is valid for Alarm, Entry/Exit, and Tech. zones types.
Inhibit
When the ‘Inhibit’ attribute is set, a user may inhibit this zone.
Normally
Open
When the ‘Normally Open’ attribute is set, the system expects that a connected detector/sensor is a Normally
Open device. (i.e. a sensor is deemed to be activated whenever the contacts are closed on the device ).
Silent
If the ‘Silent’ attribute is set then there will be no audio or visual indications of the Alarm. The alarm activation
will be sent to the Receiver station. If the system is unset then a warning message is shown on the display.
Log
If this attribute is set then all zone state changes are logged.
END
OF
LINE
The End Of Line (EOL) attribute provides a number of input zone wiring configurations on the system.
ANALYSED
The Analysed Attribute must be set for a zone if that zone is wired with an inertial sensor. The Pulse count and
Gross attack values should be programmed for each inertial sensor on the system in accordance with the
results of a simple calibration of the device.
Final Set
The Final Set attribute can only be assigned to an Entry/Exit Zone type. Use this attribute to override the
standard process of counting down the exit timer whenever the system is full set. When all other entry/exit
routes in the premises are closed, fullset the system and close the final exit/entry zone. As soon as the door is
closed the Final Exit time will count down to arming the system.
