OUTPUTS
All connection points of the control unit can be programmed as inputs
or outputs. If programmed as outputs they are of Open Collector type
which provide a negative when they are active.
A 12 VDC short circuit with an active output for a prolonged time
can lead to the protection resistance failure.

Acoustic/Visual (max load 50mA):
If you want to control a relay with an Open Collector output (or relay
output), it is necessary to add a diode (1N4007) in parallel to the
relay coil.
RELAY 1 - RELAY 2- RELAY 3 ALARM RELAY OUTPUTS
Relay outputs 2 and 3 are programmable, while relay output 1 always
follows the general alarm and sabotage status and remains active for
the programmed time.
Note: PXC2-32 has only relay 1, PXC2-64 has Relay 1 and Relay 2,
while PXC2-212 has Relay 1-2-3.
