Installer Menu Options
Part Set
(Only visible in a Partioned system.) When a partition is Part Set, zones in that
partition with this attribute are set. Note that if a zone is in more than one partition, all
partitions have to be set or part set before this zone will be set.
You can apply this attribute to the following zone types: Normal Alarm, Final Exit and
Entry Route.
Omittable
A) When a zone has this attribute, a user can omit it before setting the system.
B) If a user tries to set the system when a zone with this attribute is open (active) the
control unit alerts them and pauses the setting procedure. The user can acknowledge
the alert by pressing  and continue setting. You must enable this feature in the
System Options – User Access – Quick Omit menu, see page 87.
Note:
1. This attribute applies to the following zone types only: Normal Alarm, 24hr,
Technical, Entry Route, Tamper, External PSU A/C Fail, External PSU Battery Fault,
External PSU Low Volts and External PSU Fault.
2. Take care when assigning the Omittable option to an Entry Route zone when
Quick Omit is enabled. There is a risk that the user may omit the Entry Route zone in
error.
If the system you are installing communicates using Fast Format or with a plug-by
communicator, then you must program either a Fast Format channel or a plug-by
output as Zone Omit. This ensures that the control unit can communicate an omit
event if the user omits a zone.
Force Set Omit
When this attribute is set to Yes a user with a remote control can set the system
while the zone is open (active). (You must enable this feature in the System Options
– Force Set menu. See page 101.)
You can apply this attribute to Normal Alarm, Entry Route, Technical, Tamper,
External PSU A/C Fail, External PSU Battery Fault, External PSU Low Volts and
External PSU Fault.
Masking
30 40 50 160
Apply this attribute EITHER if you have connected a detector that reports masking by
changing the resistance between its mask/fault contacts, OR if you have connected
the masking/trouble contacts of a detector using the "3 resistor method". (For details
of wiring trouble/masking contacts see Fully Supervised Loop Connections in the
Installer Guide for the control unit.) Note that you must enable "Masking" in System
Options to make this attribute visible. See page 93 for more details on programming
masking options.
You can apply this attribute to Normal Alarm, Final Exit and Entry Route zone types.
Note: You cannot apply the Masking and the Inverted attributes at the same time.
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.
