4.10 Using shunt groups
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 and 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.
