23.17 Zone attributes
The zone attributes on the SPC system determine the manner in which the programmed zone types
function.
Zone attribute
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 and 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 and 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 and 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.
Unset Local
When this attribute is set, an alarm generated by the zone opening when the area is fullset or
partset will be reported in the usual way. However, if the area is unset there will be only a local
alarm i.e keypad buzzer, LED flash and zone display. This attribute is only applicable to Alarm, Fire
and Seismic zones.
Double Knock
Use this attribute to deal with troublesome detectors (for example, some detectors may generate
activation signals spuriously, thereby inadvertently trigger alarms on the system).
If the same double knock zone activates twice during the double knock period, then an alarm is
generated. Double knock time is set in seconds (see
on page 261). 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.
