7.5 Safety Precautions
After Powering-up, the detector requires hardly any attention in order to function
properly, but the following should be noted:
1 Follow the instructions in the manual and refer to the drawings and
specifications issued by the manufacturer.
2 Do not expose the detector to radiation of any kind unless required for testing
purposes.
3 Do not open the detector housing, while power is supplied.
4 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.
5 Disconnect external devices, such as automatic extinguishing systems before
carrying out any maintenance.
