Recovery procedure
If the installer PIN is lost, installer access is impossible. In this case the installer
can perform a recovery procedure.
To recover installer access:
1. Remove mains and battery power from the panel.
2. Set jumper T1.
3. Apply power to the panel.
During the next 3 minutes, it will be possible to access the installer menu using
the default code. No user is required to provide access to installer programming
mode.
This procedure is logged.
Note: The recovery procedure is not allowed if the “8.2.3 Engineer lockout”
option is set to Yes.
Caution: After the recovery procedure keypad 1 access limitations are reset,
which allows you to view and control all areas from this keypad. See “2.2.1.n.3.3
View areas” on page 144 and “2.2.1.n.3.5 Control areas” on page 145 for more
details.
