Field Wiring - Fire-Lite MP-24 Instruction Manual

Field Wiring

All field wiring connections are made to the screw
type terminal blocks, located along the edges of the
PC boards, as shown in wiring diagrams. Wiring
should be in accordance with National and/or Local
Codes for fire alarm systems. Use knockouts
provided on back and side of cabinet.
UL Power Limited Wiring Requirements
Power limited and non-power limited circuit wiring must remain separated in the cabinet. All power limited
circuit wiring must remain at least 0.25" away from any non-power limited circuit wiring. Furthermore, all
power limited circuit wiring and non-power limited circuit wiring must enter and exit the cabinet through differ-
ent knockouts and/or conduits. Create knockouts if necessary.
• For side knockouts, place the wire ties as shown in Figure 4.4.
• Use a lower knockout to run the wiring for non-power limited circuits and the upper knockout for
power limited circuits.
