Connection variants
1. Input open
To activate this variant, you do not
need to take any further steps be-
fore integrating into the radio group.
Alarm is triggered if:
A DC voltage between 3-24V DC
•
is connected to the alarm input,
or
The contact on the alarm
•
input is bridged, e.g. with a
switch (short circuit)
2. Input closed (cable-break proof)
f To activate this variant, and prior to
integrating the alarm relay into the
radio group, either connect a closed
circuit to the alarm input which
does not exceed the switching
threshold of �1,6V or bridge the
contact without applying a voltage.

Operating Manual: PX - AR Alarm Relay
The bridge on the contact or the
circuit on the input (e.g. using
a NC contact) is broken.
A voltage is applied which exceeds
the switching threshold of �1,6V.
the device is integrated into the
radio group, a voltage of between
3 and 24V must be present at the
alarm input.
The applied voltage is interrupted or
The voltage drops below the
switching threshold of �1,6V.
