Section 8: Power-Limited
– Non Power-Limited Wiring
UL Standard 864, (Control Units for Fire Protective Signaling Systems), requires that a minimum
of 1/4 inch separation be maintained between power-limited circuits and non power-limited
circuits. The control unit is designed so the required separation between these circuits (power-
limited vs. non power-limited) is maintained at the field wiring terminals.
In order to fully comply with the intent of these requirements, however, the minimum 1/4 inch
separation must also be maintained between the field wiring conductors of power-limited circuits
and non power-limited circuits. This may be accomplished by routing the field wiring as shown in
Figure 8.2.1.
Unless otherwise indicated on the unit, all field-wiring circuits are power-limited except:
•
AC power circuit
•
Standby battery circuit
•
Telephone line connections
•
Master Box / Releasing
