Output: alarm output
[Alout]
This output is a npn-transistor output, so not potential-free. This transistor output
switches between floating and 0 [Supply-].
For properties of a npn-transistor output, see previous page 17.
This npn-transistor output is represented on the PCB by connectors [Alout].
The transistor conducts as soon as the unit switches to alarm mode or to panic
mode.
The transistor output floats if:
a) the panic mode is switched off, or
b) automatically, 3 minutes after the last fog expulsion.
c) the running alarm mode is switched off because the unit’s guard mode has been switched
off through the guard input.
A common application of this handy [Alout] output is to connect this output through a seperated
relay with an auto dialer (to report the alarm condition) or to activate/deactivate directly
an external siren.
