Final tests

After installation, make sure everything is working with an overall system test.
For SB250 and SB2100 detectors:
• Interupting the beam (intruder alarm).
• Prolonged interuption of the beam for more than 1 minute (interuption alarm).
For SB450, SB4100 and SB4200 detectors:
• Interupting the beam of just one of the two cells: alarm not triggered.
• Interupting the beam of both cells: intruder alarm.
• Prolonged interuption of both beams for more than 1 minute (interuption alarm).

10. Regular maintenance

To keep good ongoing performance levels, minimal maintenance is required:
• Clean the infrared covers of each module at least once a year (or more often,
depending on exposure to soiling).
• Repeat the final tests (once a year).
