Typical Wiring of an external alarm device using an intermediate circuit:
Configuring the Alarm Output
5.4.2.
It is possible to configure the alarm output to either latch for the duration of the alarm condition or to
give a single one-second pulse when the alarm first occurs. The choice of output depends upon the
requirement of the external device that you intend to connect the output to. The factory setting for the
Alarm output is to latch. You will only need to change this setting if you need a pulsed Alarm output or
if the unit has been used previously and the current settings are not known.
The procedure for setting the Alarm Output mode is as follows:
