Fuse Alarm Panel with
Bay Alarms
22. With PWR ON A and B lit (normal operation), test the power-fail relay and contacts at the
PWR ALM terminals on the rear of the panel:
•Expect continuity (0Ω) between Terminals Cand NC.
•Expect an open circuit (∞Ω) between Terminals Cand NO.
23. Make sure none of the fuse positions contain fuses.
24. For TPA output wiring, crimp single-hole lugs onto one end of the #18 to #6 AWG copper output wires, as
required by NEC. (Work with one output wire at a time.)
25. Clean the panel terminals and lugs with a nonabrasive, nonmetallic pad.
26. Amphenol Network Solutions recommends a light coat of antioxidant on the lugs and output BATTERY and
RETURN terminals before connecting lugs to the terminals, as shown in Figure 9. (NEC specifies only one lug
and load at each output terminal.)
27. Tighten nuts to 20 in.-lb. (~2.3 N•m) and then
connect the other end of output wire to load.
28. For GMT output wiring, use #20 to #12 AWG
copper wire. (Work with one wire at a time.) At
the panel end of the wire, either:
•Crimp a single-hole ring or fork lug, as
required by NEC.
OR
•Strip ⅜in. (1 cm) of insulation for a bare
wire connection.
29. Clean the panel terminals and lug (if applicable)
with a nonabrasive, nonmetallic pad.
30. Amphenol Network Solutions recommends a
light coating of antioxidant on the lug/wire and
output BATTERY and RETURN terminals
before connection to the terminals, as shown
for Figure 10. (NEC specifies only one load at
each output terminal.)
31. Tighten the panhead screws to no greater than
8 in.-lb. (~1 N•m) and then connect other end of
the output wire to load.
ALERT! Local electrical and operating company guidelines recommend that the individual load not exceed 80%
of input over-current device capacity (for example, 50A TPA fuse x .80 = 40A max. load). Total load for all TPA
& GMT outputs on each side must not exceed 200A.
