SENSITIVITY ADJUSTMENT

The sensor can be adjusted in accordance with the environment and
intended purpose.
Normally, use medium (100%).
Setting the sensitivity to 170% will trigger detection even at small changes
in temperature.
Use this in stable environments.
Setting the sensitivity to 30% will not trigger detection unless there is a
large change in temperature.
Use this in environments which are subject to large changes in temperature.
When changing the sensitivity dial, ensure that a walk test is carried out to check that the sensitivity is suitable.
