Your device is equipped with a remote alarm
connection to send alarm signals to a building
management system, a monitoring unit, visual
or acoustical warning device etc.
The alarm output is managed by the built in
controller of the unit.
Alarm criteria may be too low temperature,
too high temperature, power failure, open
door or similar.
The alarm output is an electrical relay which
acts like a ON/OFF switch.
A OptoMOS relay with maximum switch
rating of 60V 3A is maintained by the build-in
controller unit. The relay can be set to nor-
mally open or normally closed in the settings
menu.
The relay terminals are explained this way:
COM: COMMON terminal
NO/NC: NORMALLY OPEN/ NORMALLY
CLOSED terminal. Normal position is set in
the settings menu
An alarm interface cable of maximum
30 meters can be attached without the use of
tools to the 3-pole alarm clamp connector.
Wire thickness must be within 0.5mm2 to
2.5mm2 and fitted with core crimp terminals.
