The alarm module provides 8 alarm inputs and 8 alarm outputs. The user can assign
the corresponding relay status to the different events. There are three terminals:
COM, N.O and N.C. The wiring depends on the alarm device. Please read the user
manual of the external alarm devices before wiring. Using the 5th channel alarm
signal output as an example, the wiring is shown in Fig. 2.15 and 2.16.
