Cleaner Access
has a code which permits selected areas of the protected premises to be unset for the purpose of
cleaning or maintenance. This cleaner code works in conjunction with cleaner access points which have
been programmed by the engineer. Check your SIS to see if any points have been programmed for cleaner
access.
The cleaner code cannot be used to reset the system in alarm.
Group Shunt
The Group shunt facility allows part of the protected premises to be unset without unsetting the whole
system. This is often used to allow access to a garage or loading-bay area independently from the main
area of the protected premises. Check your SIS to see if this facility has been provided.
The detection points in the group will operate normally; they will be set when the system is set, and unset
when the system is unset. However, they can also be unset (dis-armed) at any time by operating the
group
shunt keyswitch
. Your installation engineer will give you details on how to do this.
Re-arming the group is done with the keyswitch. However, if a detection point in the group is in fault, eg a
door has been left open, the group cannot be re-armed. An led located close to the keyswitch will light, or a
buzzer may sound, when it is not possible to re-arm the group. You must dis-arm the group by the
keyswitch; this will turn off the led or buzzer. Enter the protected area and clear the faults before trying to re-
arm the group again.
