7.4 Safety Precautions
After power-up, the detector requires almost no attention in order to
function properly, but the following should be noted:
 Follow the instructions in the manual and refer to the drawings and
specifications issued by the manufacturer.
 Do not expose the detector to radiation of any kind unless required for
testing purposes.
 Do not open the detector housing while power is supplied.
 Do not touch internal parts other than the three functional switches.
Interference with internal circuits may impair detector performance and
will invalidate manufacturer's Warranty.
 Disconnect external devices, such as automatic extinguishing systems,
before carrying out any maintenance.
