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 11.
• Power-limited field wiring must be installed and routed in the non-shaded areas shown in
Figure 11, 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 11.
Figure 11. 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 UPS-style power supply, the 4100-1108 Power Supply
(8A), or a power-limited power supply that listed for fire-protective signaling use.
