Additional call repeater does not work:
Check that SAR-2Plus and additional call repeater connections are correct.
Check that the system selection jumper JP1 is properly configured (see page 38).
Check that the microswitch SW1-1 is set to ON and the rest to OFF (see page 38).
Remember is necessary to program SAR-2Plus and to be assigned to the monitor/phone of the
house where the call repeater is installed (see page 40).
The microswitch SW1-3 has been re-set to OFF once programming is finished.
Check that the fuse is fully inserted and is not blown, in this case check that the voltage and the
current of the terminals connected to the call repeater are correct (see page 33). If voltage and
current are correct, replace the fuse with one of the same characteristics (see page 33).The blown
fuse must be replaced by
and in the absence of electrical current.
The activation time of the additional call repeater is not the desired:
Check the proper adjustment of the potentiometer (see page 39).
Remember that the maximum activation time is 45 seconds.

The Lock release from relay unit does not work:
Check that SAR-2Plus and Lock release connections are correct.
Check that the system selection jumper JP1 is properly configured (see page 38).
Check that the microswitch SW1-2 is set to ON and the rest to OFF (see page 38).
Check that the fuse is fully inserted and is not blown, in this case check that the voltage and the
current of the Lock release connected to the SAR-2Plus are correct (see page 33). If voltage and
current are correct, replace the fuse with one of the same characteristics (see page 33). The blown
fuse must be replaced by
and in the absence of electrical current.
The activation time of the Lock release is not the desired:
Check the proper adjustment of the potentiometer (see page 39).
Remember that the minimum activation time is 3 seconds and the maximum is 60 seconds.

SAR-2Plus unit does not work:
Check that SAR-2Plus and auxiliary devices (lights, etc.) connections are correct.
Check that the system selection jumper JP1 is properly configured (see page 38).
Check that all microswitch are set to OFF (see page 38).
Check that the fuse is fully inserted and is not blown, in this case check that the voltage and the
current of the auxiliary device connected to the SAR-2Plus are correct (see page 33). If voltage
and current are correct, replace the fuse with one of the same characteristics (see page 33). The
blown fuse must be replaced by

The activation time of SAR-2Plus unit is not the desired:
Check the proper adjustment of the potentiometer (see page 39).

When installing a SAR-2Plus unit the picture quality is poor in the monitor:
Check that the system selection jumper JP1 is properly configured (see page 38)
Check that the End of line resistor is placed in all the SAR-2Plus units where the bus ends (see page
39).
Check that the End of line resistor is placed in the last distributor.
