About shunt groups
A shunt group is a collection of zones that can be “shunted”. “Shunting” is
another way of preventing a zone from causing an alarm. The difference
between shunting and omitting a zone is the length of time that the control
unit ignores the zone. When you omit a zone (see the previous section),
the control unit ignores it for one setting/unsetting cycle. When you shunt a
zone, the control unit ignores it until you unshunt it.
The installer sets up the shunt groups, each of which can consist of one or
more zones. You should agree with the installer what zones need to go into
each shunt group, and record that information. A zone can be in more than
one shunt group.
Once the shunt groups are defined, there are three ways of shunting them:
a) Master and admin users can use the
Shunt Groups
option to shunt all
zones in selected shunt group. A master user can select any shunt
group. In a partitioned system, an admin user can select any shunt
group in the same partition as the admin user.
b) A master user can use the
Users
– Add User
option to add a Shunt
Code user type and assign a shunt group to that user. When the code
is used at a keypad, all zones in the shunt group are shunted. When
the code is used again, the zones are unshunted.
c) The installer can fit a key switch to a special zone, and link the zone to
one or more shunt groups. Turning the key shunts all zones in the
shunt groups. Turning the key again unshunts them.
When a user tries to set the system or a partition where zones are shunted,
the keypad displays
“Shunt Active tick to continue”. If the user presses
,
the system continues to set.
