suitable User Codes / tags at appropriate
keypads / readers.
Applies to 24-hour tamper, or other Input types
that would generate an alarm condition if the
system were returned to disarmed mode. Also
applies to tamper fault on other Input types.
Check for fault on Input, or omit in programming.
It would therefore be impossible to fully disarm
the system after a tamper alarm on that Input.
Programming must be adjusted before exiting
Engineer mode.
