Prepare a System Wiring Diagram
Using Section 3-4 (Page 3-8), prepare a complete system-wiring diagram.
Keep a copy of the system-wiring diagram with the SP40/2 manual as a permanent record of the
system wiring.
Unpack and Inventory
Carefully unpack the SP40/2 panel and make sure each item described on the packing slip is present
and undamaged.
Mounting
1. Mount the SP40/2 panel and optional expansion modules in the desired locations as described in
Section 3-5 (Page 3-13).
2. Mount any additional wiring boxes or junction boxes needed to interconnect field wiring.
3. Connect conduit fittings or bushings as needed through the knockouts provided on the top and
bottom of the SP40/2 panel.
Field Wiring Connections
NOTE: The terminal blocks on the SP40/2 are removable. To remove a terminal block, pull the block
straight up from the circuit board, as shown in Figure 3-2. Attach wires to the desired connections,
then plug the terminal block back on the board being careful to match the pins.

Removable Terminal Block
NOTE: For power limited circuits all input power sources (Alarm and Trouble relay
connections, NAC inputs, and auxiliary inputs) must be power limited.
NOTE: The AC Power input wiring is non-power limited and shall be routed on the left side of the
enclosure. All power limited inputs and outputs shall be routed on the right side of the enclosure.
Install field wiring in conduit when required, following the most current National Electrical Code
(NFPA-70) and local codes for the type of system being installed. Make all necessary connections at
any additional wiring or junction boxes.
CAUTION: Provide proper strain relief for all wiring not in conduit.
NOTE: Shielded wire is not required on any circuit. If shielded wire is used, connect the shields to
the ground terminal strip as shown in Figure 3-14 on Page 3-14.
