P. 11 - Inputs - Guard input
Guard input
[Grdin] (G+ / G-)
Through this input
BANDIT
is told the
alarm system is in ‘guard’ mode.
As long as this message is valid, the unit
also will be in ‘guard’ mode’. Only if
BANDIT
is in guard mode, is it possible to
proceed to alarm mode through activating
the alarm input.
Properties of the “guard”mode:
4
The red LED "Guard" on the front panel will light up, as long as the unit is in ‘guard’mode.
4
Eventual LED-warnings on the front panel such as: failure, HY-3 and power? stay off in all
circumstances. The green OK-LED on the front pannel reamins on. This way, a unit which
is in ‘guard’ mode will never show the outside world, that there might be a possible
technical failure.
Configuring the guard input [Grdin]:
This input can be activated either with 12 V supply or without power supply. Depending on
the position of dipswitch A1, the guard mode will be active with 12 V supply over the input, or
active without power supply over this input.
As long as there is a 12 V supply over this input, the red PCB Led [GrdinV] will be on.

This guard input [Grdin] is ignored if:
a) there is attached an optional remote control,
and
b) channel 1 and/or 2 (through Dip B1and B2) of this remote control is adjusted as guard
input.
So if a channel of the plugged-in remote control is selected as guard input, input [Grdin]
as well as Dip A1 has no function or influence.
See also p 25, Dipblock B and remote control.
