Inverted
On FSL zones, the attribute makes the control unit treat resistances in the 6k9 band
as “tamper”, and resistances below the 2k2 band as “alarm”. In 4-wire CC zones the
attribute makes the control unit treat open alarm contacts as “no alarm” and closed
alarm contacts as “alarm”. (Tamper contacts are not affected by the Invert attribute.)
You can apply this attribute to any zone type except Tamper Return and Not Used.
Linked Zone
If a zone activates that has this attribute, a second zone with this attribute must also
activate within the
Linked Zone Time
(see page 58) for an alarm to trigger.
This attribute is normally used only for an area protected by an array of infra-red
beams, with each beam connected to a separate zone.
Extended Entry Time
This attribute is only for Final Exit zone types. If enabled and the zone is triggered to
start the entry procedure, the system uses the
Extended Entry Time
setting (page
46). If disabled, the system uses the standard
Entry Time
setting (page 46).
This attribute allows for cases where you need to allow an increased length of time
for the entry procedure for certain zones. For example, you may want to allow 40
seconds for a front door, and 90 seconds for a garage entrance.
Double Doors
This attribute is available only if the zone is configured to use the 2k2/4k7 FSL wiring
method (see page 57). Setting this attribute allows the zone to monitor two door
contacts in series, providing each detector has a 4k7 shunt resistor and there is a
2k2 end-of-line resistor. Please refer to page 14 for wiring details.
To enhance system security, it is not recommended to use this attribute if only one
detector is connected to the zone.
Force Set
This attribute is for zones of type Key Switch Momentary and Key Switch Latched
only.
You may wish to allow the key switch to set the alarm system even if one or more
zones are active or have faulty detectors. This is known as a "force set". The
detectors that are active or are faulty must have the
Force Set Omit
attribute set to
Yes. When a force set occurs, the system omits the active or faulty zones and sets
the remaining zones normally.
Note:
If you enable
Force Set
, the system does not comply with EN50131.
Off
– The key switch cannot force set the system, even if you have applied the
Force
Set Omit
attribute to any zones.
On
– The key switch can force set the system.
Address Bus Device
You can use this option to:
Add new keypads to the system once they are physically wired to the bus. The
control unit assigns a bus address to each keypad you add. (You can perform the
same action using
Detectors/Devices
– Wired Keypads – Address Bus Device
.)
Re-scan the bus for any found or missing keypads.
Note:
If you need to replace or remove a keypad, please use
Delete Keypad
(page 35) or
Replace Keypad
(page 35).
