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 Timers). 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. The inhibit operation will disable that fault or zone for one setting period only.

Normal Open

When the ‘Normal Open’ attribute is set, the system expects that a connected detector/sensor is a Normally Open device (for example, 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.

Exit Open

If set then zone will be indicated if open during setting.

Frequent

This attribute only applies to remote services*. If this attribute is set for a zone, the zone must open for remote service purposes within the defined frequent time period.

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 inertia sensor. The Pulse count and Gross attack values should be programmed for each inertia sensor on the system in accordance with the results of a simple calibration of the device.

Pulse Count

Pulse count trigger level for analysed inertia sensors.

Gross Attack

Gross attack trigger level for analysed inertia sensors

Final Exit

The Final Exit 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 setting the system.

Shunt

A zone with the shunt attribute set will be inhibited whenever a shunt type zone is opened. This provides a mechanism to group the inhibition of zones with the opening of the shunt zone type.

Report Only

This attribute only applies to the FIRE zone type. If this attribute is set, then activation of the fire zone will only report the activation to the central station. No alarms will be generated on site.

Open Only

This attribute only applies to the KEYARM zone type. If set then the setting state of the building will toggle on openings only.

Fullset Enable

This attribute only applies to the KEYARM zone type. If this attribute is set then zone activation will Fullset the system/area. Apply this attribute if it is intended that the user should only have the ability to FULLSET the system from a keyarm zone.

Unset Enable

This attribute only applies to the KEYARM zone type. If set then zone activation will Unset the system/area. Apply this attribute if it is intended that the user should only have the ability to UNSET the system from a keyarm zone.

Tech Zone Report

Allows a zone when opened, regardless of the mode to send an alarm to the ARC in FF, CID, SIA and SIA extended. When areas are selected, the alarm will only be sent to the ARC to which the area has been assigned to. This would be a “UA” Unknown Alarm followed by the zone number and text if SIA extended is selected. It will also send an SMS to the end user and engineer if select to do so when the unconfirmed alarm filter is selected.

Tech Zone Display

Allows an opening zone to be displayed on the system keypad. The alert led should also activate. When areas are selected it will only be displayed on the keypad which is assigned to the area in which the zone has been selected. The alert may only be displayed on the keypad when the area is in the unset mode and not in the Part A, Part B and set mode.

Tech Zone Audible

Allows an activated zone to operate the buzzer. This will operate the same as the Tech Zone Display in the different setting modes and on systems with areas.

Tech Zone Delay

Allows the zone to have a programmable delay. The delay is variable from 0 to 9999 seconds and will apply to all Tech Zones. The operation is the same as the Mains Delay timer, if the zone is closed within the delay time, then no alarm is sent to the ARC, no SMS is sent to the user and the Technical Output will not trip.

Note: The Technical Output will not trip until the delay timer has expired.

Armed report only

Openings are reported only in armed mode.

Fire pre-alarm

If enabled and a fire alarm occurs, a Fire Pre-alarm timer is started and internal bells and buzzers are activated. (See Timers.) If the alarm is not cancelled within the timer duration, a fire alarm is confirmed, internal and external bells are triggered and an event is sent to ARC.

Fire Recognition

If enabled, a Fire Recognition timer is activated which adds extra time to the Fire Pre-alarm timer duration until a file alarm is reported for the zone. See Timers.

Seismic Test/Automatic Sensor Test

A Seismic zone type may be tested manually or automatically. This attribute allows automatic testing to be enabled. See Timers for details of how to configure the timer that determines how often the panel tests any seismic zones that have this attribute set. The default value for the timer is 7 days.

Timed

The ‘Timed’ attribute is used for Key Arm zones to delay the setting of an area. The delay follows the exit timer for the area to which the key arm is associated.

Verification

Select the configured verification zone to assign to this zone to trigger audio/video verification.

Force Set

If enabled, the keyarm device can set the system, automatically inhibiting all open zones.
