Alarm central External dialer
Dip switches:
A1:Position ON = unit in
guard only if there is
12V over [Grdin].
So if relevant output
of the central is
active(relay-contact
closed), GrdinV LED
is lit and BANDIT is in
guard mode.
A2: Position OFF = if
there is a transition
of 12V to 0 V over
[Alin] (contact opens)
while BANDIT is in
guard, the alarm
mode is activated.
This means fog
ejection during
adjusted period (dip
block C). [Alout]
becomes [Supply-].
for 3 minutes. During
these 3 minutes, the
input for alarm report
of the dialer gets 12
V and is activated for
this period.
A3: Position ON = only 12V over [Panin] can activate panic mode. Not connected, so no
function.
B1: No connection of remote control, so no function.
B2: No connection of remote control, so no function.
B3: No Control box connected, so position ON.
C1 OFF, C2 OFF, C3 ON and C4 OFF = adjusted fog ejection period is 4 seconds (see p. 25).
The technical failure input of the dialer gets 12V as long as there is a BANDIT failure through
the NC contact of [Okout].
