Alarm Relays (Form-C Outputs)
The Model 6103 is equipped with two Form-C relay outputs presented on
a DB-9 connector located on the rear panel (see Figure 1 on page 6). In
the event of an alarm, the Model 6103 will complete one of two circuits
through this Form-C connector.
A Form-C relay has three contacts: normally open (N.O.), normally closed
(N.C.), and a common contact. When no alarm is issued, the Form-C relay
will connect common to N.C. In the event of an alarm, the common contact
will connect to the normally-open (N.O.) contact. If it is a minor alarm, the
Model 6103 will connect pin 5 to pin 9. In the event of a major alarm, the
Model 6103 will connect pin 2 to pin 6.
Note
Contact rated load is 12 amps at 24 VDC.
Alarm Cut Off Switch
The Model 6103 is equipped with an alarm cut-off switch (ACO) on the
rear panel as shown in Figure 1 on page 6. If an alarm occurs and you
want to turn off the form-C output, press the ACO button to do so.
Note
The LED on the Model 6103 will remain yellow for the offending
alarm and will remain lit until the alarm is cleared. Subsequent
alarms will retrigger the alarm relay indicating the presence of a
new alarm.
