WARNINGS
LETHAL HAZARD - ELECTRICAL SUPPLIES. A current of 100 mA passing
through the body for one second can kill. This can occur at voltages as low as
35V ac or 50V dc.
LETHAL HAZARD - The control board and power supply are combined on a
single board therefore this board contains high AC/DC voltages. A grounded
mesh screen cover protects the power supply area of the main control board.
Failure to fit or refit this cover securely may expose the user to a risk of electric
shock or may result in permanent damage to the detector.
AC wiring colours will vary according to territory.
