Appendix B: SLC Surge Suppression
B.1 Introduction
There are one primary and three secondary UL–listed surge protectors approved for use with the FACPs listed in this appendix.
Primary Surge Protector:
• 326-2M TII Station Protector
Secondary Surge Protectors:
• DTK-2LVLP-F: Diversified Technology Group, Inc. (DITEK) 1720 Starkey Rd. Largo, FL 33771 (800) 753-2345
• SLCP-30: EDCO 1805 N.E. 19th Ave. Ocala, FL 34470 (352) 732-3029
• PLP-42N: Northern Technologies, Inc. 23123 E. Madison Ave. Liberty Lake, WA 99019 (800) 727-9119
One primary surge protector must be used with each SLC wiring pair whenever SLC wiring runs outside the building.
• Install primary protection only as shown in this document.
• Refer to NEC Article 800 and local building code requirements.
Additional primary surge suppressors may be added as required by the NEC. Add these additional suppressors in series with the SLC
wiring at the building entry/exit.
Wiring connected to the surge suppressor output must remain within the building while wiring connected to the surge suppressor input
may be routed outside the building as shown below.
B.2 Installation
Mounting of the secondary surge suppressor must be inside the FACP enclosure or in a separate enclosure listed for fire protective sig-
naling use.
• Locate on an available stud and secure with nut.
• Unit is connected in series with the SLC Loop to protect the Control Panel.
• Provide a common ground to eliminate the possibility of a differential in ground potentials.
NOTE: For detailed information refer to the installation documentation supplied with the unit.
