NAC pattern assignment
Every zone is assigned to one NAC pattern. When the zone NAC pattern is set to default, the
device NAC pattern is used. In case of a device activation by address, the device NAC pattern
is used. When a device is activated by a zone activation command, the NAC activates with the
assigned zone pattern (Steady, Pulsing, or Temporal Code 3, for global gas alarm also
Temporal Code 4). See the following table.

Counting zones
All local or group zones have the "Counting Zones" option. If this option is enabled, a local or
group zone becomes a counting zone.
Otherwise, it is a non-counting zone which is activated as soon as an input point assigned to
this zone is activated. If multiple points (can be from different panels if networked) are
assigned to a single zone, only when all the points are inactive is the zone considered as
inactive; thus, associated outputs can be deactivated.
A counting zone is considered active only when two or more input points assigned to that
zone are active. It is not allowed to assign an input point programmed with any delayed point
features (including PAS, Pre-signal, alarm verification, and PAS@day or
alarmverification@night) to a counting zone.
Notice!
When implementing the counting zone feature, a minimum of two detectors is required in
each protective space. Also all points on the ceiling shall have a detector within a distance
equal to 0.7 times the listed spacing (0.7S).
Bypassing zones
If a user bypasses a zone, all inputs and outputs assigned to this zone are bypassed. Bypassed
elements are processed as trouble conditions. Events from bypassed elements are ignored
until restored or unbypassed.
Zone status display
If a zone is activated, the corresponding zone LED on the remote LED annunciator is turned
on. If the zone is deactivated, the corresponding LED is turned off.
