Connecting alarm and time signal inputs
The alarm and time signal switches are connected across poles 4 and 5 of the 5-pole DIN con-
nectors. The alarm signal will be activated by opening or closing the switch (depending on the
normally closed/normally open setting described in section 1.3). Refer to fig. 1.14. The DIN
connectors are shown in fig. 1.12, fig. 1.13 and fig. 1.14.
