Additional measuring channels for smoke measurement
The VisGuard 2 can be used as both a visibility detector and smoke detector. To do this, a
mode is available where the VisGuard 2 acts in the same way as a FireGuard 2 smoke detec-
tor (see Reference Manual).
To enable this function, the following channels are available in addition to the channel used
for measuring the turbidity (
Turb
):
Turbidity gradient (
Turb.Gr
): Change in turbidity per minute
Temperature (
Temp
): Inner temperature of the instrument
Temperature gradient (
Temp.Gr
): Change in temperature per minute
Turbidity value without integration time (
Turb 0s
): For smoke detection
The temperature measurement is an internal measurement that reacts with a delay.
