Automatic Unsetting
The system may have been programmed by the installation engineer to automatically unset all or
parts of the system according to a pre-programmed schedule. The schedule will have been
programmed to take into account the normal opening time, non-working days and holidays.
Unsetting Warnings
When unsetting from a keypad, the user is informed on the display of any warnings, e.g. circuits
isolated or on soak. The warning display will appear for approximately 4 seconds during the unsetting
procedure. If more than one warning exists, the display will automatically scroll through the list of
warnings.

Isolated
The unset warnings are:
1. Bypassed circuit(s) (the circuit must have a 24hr response)
2. Circuit(s) on soak test has failed (a special circuit test mode set up by
the installation engineer)
3. Isolated circuit(s)
4. Line Fault (only when setting with telephone line fault is allowed)
5. Shunted circuit(s)
6. Circuit has reached the programmed multiple alarm limit
7. Battery test faults
8. 230v mains faults
Unsetting Restrictions
The selected group is programmed with a set level and a higher level set group(s) has not been
unset. If a user attempts to unset a high level set group when a lower level is set then a warning
message will be displayed.
In a PX250HS, there are several additional conditions that apply when unsetting.
1. The keypad must be programmed by the engineer to allow unset
2. The selected group may be programmed for dual user unset
3. An open/close schedule may be programmed for the selected group and the time is after the
programmed close time. This condition may be ignored following an alarm in one of the set group
areas if the set group is programmed with an alarm unset time. In this case, after unsetting, the
set group will automatically set after the programmed Alarm Unset period.
4. The selected group may be programmed with an Unset Delay time and set group will only unset
at the end of the programmed unset delay period. A message will be displayed during this time
and the user unset request will be logged.
5. If a group is manually set before the scheduled set time then it may be unset up to the number of
programmed Early Set minutes after the time the group was set.
