Selectable device functions
The device has selectable functions. They should be selected
to suit the respective application.
When the cap on the MSM is unscrewed, DIP switches can be
accessed to select the desired configuration. For this two DIP
switches must always be set in the same position, depending
on function (see Table 2).
The configurations are:
Sensor test
Setting of whether testable or non-testable muting sensors are
connected.
Concurrence monitoring
The sensors of one sensor pair must be activated within
3 seconds when the function is selected; otherwise no muting
is possible. The function is intended to protect against
manipulation (e.g. masking of an optical sensor). Therefore only
activates when the condition is satisfied.
