These checks must be performed with the detector isolated from all installations
and supplied with the correct electrical power.
It is assumed that the connection and the electrical continuities have been
checked beforehand.
Note: the troubleshooting guide follows a chronological order and a methodology which
is the result of the experience of Alcatel CIT Customer Service. It is therefore recommended
to follow this order so as to locate faults effectively.
