Wiring
Wire in accordance with NFPA 72 or CAN/ULC-S524. Be sure
to observe the polarity of the terminals on the terminal block as
shown in the diagram.
Break the wire run at each terminal. Do not loop signaling
circuit field wires around terminals.
Caution: To avoid accidental damage to the panel, disconnect
all power before wiring the unit.
Note: If shielded cable is used, the following recommendations
apply:
• Shielded wire is required only in environments with very
high electrical noise.
• Use of shield connections must be continuous and must
be insulated from ground. Electrical tape is recommended
as a minimum to insulate the shield.
• For Class B wiring, all shields must be continuous and
insulated from ground, except at the originating panel.
