The A1 Alarm outputs are DPDT relays, 1 open collector output (A1-OC) that follows the
logic of the relays and 1 open collector output (LA1) that follows the blinking pattern of
the front panel LED. The A1-C1 designation is common for A1-1 & A1-2. The A1-C2
designation is common for A1-3 & A1-4. The normally open (NO) and normally closed
(NC) contacts depend on a user selectable option (see Chapter 5).
The table below refers to the proper open and closed A1 alarm relay contacts while the
