2.15 Separation of Circuits
2.15.1 S3 Series, SLP-BB 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 that the required separation between these circuits (Class 2 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 Class 2 power-limited circuits and non power-lim-
ited circuits. This may be accomplished by routing the field wiring as shown in Figure 2.15.1.1 and
Figure 2.15.1.2.
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 2.15.1.1 illustrates the S3 Series System, SLP-BB Cabinet, Class 2 power-limited and non-power-lim-
ited wiring extending from the DACT-E3, RPT-E3-UTP and SLC-PM/SLC95-PM modules.
