Outputs
The unit has a total of 5 outputs:
1. The 12 volt supply output [Supply] (fixed defined). See further
this page.
2. The
3. [OKout] is a technical failure output. See page 16.
4. [Grdout] is a npn-transistor output, active with guard mode. See page 17.
5. [Alout] is a npn-transistor output, active in with alarm mode. See page 18.
The properties of the different outputs are described as follows:

low voltage circuit
The [Supply] output can offer a maximum of 500 mA (restricted by F2). In normal conditions
and with full charged battery under loading current, the voltage is ~13 volt.This voltage is
practically ripple free (10mV ripple) and is used as supply for small external power users,
such as external inner siren, Jumbo-LEDand PIR-sensors. It is also a useful power supply
for external relay contacts, to send back voltage signals to the inputs of the unit.
The presence of this 12 V and the good condition of F2 is continuously being checked through
BANDIT
-internal electronics. If a fuse blows, the frontLED "failure" and the red PCB error LED
will blink and the technical output [OKout] switches to rest condition.
As a precaution, make sure the continuous load rate of this output [Supply1] isn’t higher
than ~450 mA.
F
It is important that
BANDIT
power supply never interferes with the power supply of the
controlling alarm system or with other devices which also have their own power supply.
Also never connect the grounds with each other. This can result in unexpected earthloops
(high potential differences, especially in case of lightning and similar overloads) with all
bad consequences.
