Masking
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 detecto
r using the “3 resistor method” (see the
installation instructions). Note that you must enable
System Options
– Masking
(page
66) to make this attribute visible.
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.
Note:
You cannot apply the Inverted and the Masking attributes at the same time.
The Inverted attribute does not apply to radio zones.
Shuntable
Apply this attribute to zones that you wish to be shunted.
If you give a zone this attribute, you may also want to assign the zone to a shunt
group (see page 68).
If you wish to set up a shunt key, see page 29.
Supervision
This attribute is available for radio zones (not wired zones), and allows you to
enable/disable supervision for individual zones.
When set to Yes (the default), supervision for this zone is the same as the selected
option in
System Options
– Supervision
(see page 72). When set to No, supervision
is disabled for his zone.
Reset
Enable this attribute if you have connected a latching type of shock or vibration
sensor to a zone. You will also need to program an output of type Shock Sensor
Reset.
The control unit ignores the zone during setting while the Shock Sensor Reset output
is active, and for an extra three seconds after the output restores.
Note:
It is recommended that you set the exit time to a value not less than 10
seconds to allow detectors to reset correctly and avoid the possibility that the control
unit will isolate a zone that has not reset.
If the exit time is less than 10 seconds and the detector does not successfully reset
(it remains in an active state), the control unit will not add the detector back to the
system until detector becomes inactive. This is to prevent false alarms.
On-board Keypad
You can use
this option
to change settings for the keypad fitted in the control unit.
Home Key Action
Choose the action of the keypad's Home key:
Not Used
The key has no function.
