Form C Relay Contact Outputs.
The center of the back panel has connections to
the Form C relay contact outputs for connection to external audible or visual alarm
circuits. See Figure 7 below.

Figure 7. Alarm Connection Detail
Connection is made via two Phoenix Contact spring clamp terminal blocks. J3 is for
the Form C relay contact of side B and J4 is for the Form C relay contact of side B.
Terminals 1, 2 and 3 viewed from left to right are the normally open (NO) common
(C) and normally closed (NC) contacts, respectively. See figure 8 below.
“Normally Closed” and “Normally Open” are defined with the distribution panel
powered and providing power to all outputs, i.e., no circuit breakers tripped.
The ratings of the relay contacts are 0.6A at 125VAC or 2A at 30VDC. The spring
clamp terminals accept wire sizes nos. 16 to 26 AWG.
When the input power is connected to a side (A or B), the Form C relay of that side is
energized. If there is either loss of input power, one or more circuit breakers trip or
the relay is de-energized, the normally open contacts close and the normally closed
contacts open. See figure 8 below.
