Power-Limited Guidelines
Make sure these guidelines are accounted for before wiring for power-limited systems:
• Non-power-limited field wiring (AC power, batteries, City connection) must be installed and routed in the shaded areas shown in Figure 9.
• Power-limited field wiring must be installed and routed in the non-shaded areas shown in Figure 9, with the exception of City wiring.
• Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together using the
wire ties provided with the equipment. Anchor power-limited wiring to tie points, as shown in Figure 9.
Figure 9: Power-Limited Wiring
• Tie the wiring located between bays to the internal wiring troughs, if applicable.
• When powering remote units or switching power through relay contacts, power for these circuits must be provided by a power-limited power
supply that listed for fire-protective signaling use.
