stop button
latching
* All switches are
NC-contacts and
shown in the
actuated state.
None of the
switches shown in
this circuit
diagram are
supplied with the
DFS/PFS units.
These are only
used to illustrate
how a circuit can
be opened in
order to activate
the DFS/PFS
units in the event
of a fire.
Which type of
switch is used, is
up to the installer
and the number of
interruption points
does not matter,
as long as they
are connected in
series and each
individual isolater
interrupts the AC-
power supply to
the DFS/PFS
units in the event
of a fire.
