Alarm output
This output is accessible on terminals on the bottom side of the Multilogger.
Here are available these signals: OUT - open collector transistor, +5V
power supply from external power source and GND terminal (see also the
diagram in
Appendix 2 ).
As the default, this output transistor is switched during selected alarms. It is
possible to set inverse behavior in the device's configuration (in this case
loss of external power supply acts as an alarm state). Activity of this output
can be canceled from the Multilogger keypad or remotely from a PC or
web. Remember to set a suitable alarms delay to prevent false activity of
this output.
It is possible to connect to this output:

External audio alarm (optional accessory MP026) - connect the +5 V
terminal with the central lead of the CINCH connector of the audio alarm
unit and the OUT terminal with the outer lead of CINCH connector (see
the picture).
ATTENTION - the External audio alarm unit will not work if the
Multilogger does not have an external power supply.

Telephone dialer (optional accessory MP002) - in case of alarm
telephone dialer dials specified telephone number and announces voice
message. Connect the dialer according to its operation manual.

External alarm with its own power supply - make the connection
according to the following picture. Be careful do not exceed the
maximum allowed output current from OUT terminal (see the part
Technical Parameters). Use an external relay for higher currents.
