Array ( [name] => AutomaticGainControl [title] => Automatic Gain Control [content] => Over time dust will build up on the lenses of the system which will attenuate the beam. To compensate for this the system has Automatic Gain Control (AGC). This allows the beam to operate for longer without the need for cleaning by compensating for any change in the signal strength of the beam due to dust build up. Eventually the AGC will hit a limit, and will require cleaning – as with all optical beam smoke detectors. Over time buildings will settle slightly, or expand and contract as the seasons change. AGC is also used to compensate for this where the alignment of the beam is affected as a result. Again, this would cause a change in signal for which the beam will try and compensate for.
