1. Connect external wiring to the
appropriate points on Power Supplies.
Refer to Figure 3-23A for terminal
locations for EQP21X0PS(-X).
Refer to Figure 3-23B for terminal
locations for EQP2410PS(-P) Converter.
Refer to Figure 3-23C for terminal locations
for EQP2120PS(-X) with EQP2410PS(-P)
Converter.
2. Connect the 24 Vdc output to the
Redundancy Module. (Redundant “+” and
“–” power supply terminals are connected
internally.)
3. To ensure compliance with NFPA 72,
primary and secondary power supplies
shall be monitored for the presence of
voltage at the point of connection to the
system. Connect the power supply unit for
preferred preventive function monitoring.
Refer to Figure 3-22 for an example of
power supply relays wired in series for
power monitoring.
NOTE
Contacts are closed during normal
operation. The circuit shall be wired to
an input on the EQP system (EDIO or
IDC). In Logic, the selected input must
be inverted and used to activate an
alarm trigger gate, which initiates a fault
message on the Controller and activates
the fault relay output.
No supervision is necessary, since the
EDIO or IDC module must be installed in
the same cabinet with EQP21X0PS and
EQP2410PS.
For USCG Approved System monitoring
details, refer to Appendix D.
