Connect one or both of the chassis ground connectors (labeled "C. GND") to the equipment rack
ground (see
• Chassis grounding conductor connection point: #10 screws and nuts on 0.625 inch
(15.875 mm) centers. Two #10 crimp ring terminals, for use with #10 AWG wires, are
provided.
• Chassis ground conductor: Use two #10 AWG wires if using both chassis ground
connectors or one #6 AWG wire if using one chassis ground connector from connector(s)
to equipment rack.
• Torque the nuts to approximately 15 pound-force inches (1.7 Newton meters).
CONNECT TO ALARMS USING #22 TO #26 AWG COPPER WIRE WITH INSULATION STRIPPED BACK.
CONNECT TO AUDIO ALARMS
CONNECT TO VISUAL ALARMS
CONNECT TO REMOTE ALARMS
USE TWO #10 AWG WIRES IF USING BOTH CHASSIS GROUND CONNECTORS OR ONE #6 AWG WIRE IF USING ONLY
ONE CHASSIS GROUND CONNECTOR.
TWO #10 CRIMP RING TERMINALS FOR ATTACHING THE #10 WIRES TO THE CHASSIS CONNECTORS ARE PROVIDED
WITH THE FUSE PANEL.
MAXIMUM WIDTH OF CONNECTORS IS 0.625 INCH (15.875 MM).
PLACE THE RING TERMINALS OVER THE CHASSIS SCREWS AND TIGHTEN THE NUTS DOWN ON THE TERMINALS
TO APPROXIMATELY 15 POUND-FORCE INCHES (1.7 NEWTON METERS).
CONNECT THE WIRE(S) TO THE EQUIPMENT RACK.

External Alarm Contact Connectors
Connect each set of external alarm contacts to an external system alarm as required:
• Wire wrap terminal block: Connect alarm system leads to appropriate wire wrap pins. Use
#22 to #26 AWG copper wire (see
• Screw-down terminal block: Connect alarm system leads to appropriate terminals. Use
#16 to #30 AWG wire with crimp-on spade lug or ring connectors that have a maximum
width of 0.200 inches (5.080 mm) or use #16 to #30 AWG wire without lugs (see
