2.17 Separation of Circuits
2.17.1 S3 Series, B-Size Cabinet, Class 2 Power-Limited/Non Power-Limited
Wiring Requirements
UL Standard 864, (Control Units for Fire Protective Signaling Systems), requires that a minimum of 1/4 inch
separation be maintained between Class 2 power-limited circuits and non power-limited circuits. The control
unit is designed so the required separation between these circuits (Class 2 power-limited vs. non power-lim-
ited) 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 Class 2 power-limited circuits and non power-lim-
ited circuits. This may be accomplished by routing the field wiring as shown in Figure 2.17.1.1 and
Unless otherwise indicated on the unit, all field-wiring circuits are Class 2 power-limited except:
•
AC power circuit
•
Standby battery circuit
•
Telephone line connections
•
Master Box / Releasing
Figure 2.17.1.1 illustrates the S3 Series System, B-Size cabinet, Class 2 power-limited and non-power-limited
wiring extending from the SLP-E3 and FLPS-7 modules.
