Wiring Instruction 􀁹 To ensure proper installation of the detector head to the base, wires shall be dressed properly at the time of installation 􀁹 When using PAD100 Bases, observe the correct polarity of SLC wiring. NOTICE: 􀁹 THE WIRING TO BE USED SHALL BE IN ACCORDANCE WITH THE PROVISIONS OF ARTICLE 300 .3(B) OF THE NATIONAL ELECTRICAL CODE, NFPA 70, AS WELL AS ARTICLE 210. 􀁹 THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL FIRE PROTECTION ASSOCIATION STANDARD 72. CAUTION! Break wire runs to provide supervision for connections made to each wire pair. Detector Base Mounting PAD100-IB, PAD100-RB and PAD100-SB should be mounted directly on the electrical box. The PAD100-IB, PAD100-RB and PAD100-SB mounting holes are configured for a single gang, 4”octagon or 4”square box. Use a box for each base and run the power circuit to all base locations. FIGURE 3: Wiring (Class X) Using PAD100-IB Manual Number: 550-0671 Use 12 to 22 AWG conductors to connect to terminals of bases. It is recommended that the SLC conductors be color-coded to avoid wiring errors and assist in system troubleshooting. Improper SLC connections may prevent the system from operating normally. Disconnect power to the SLC until the detectors are installed. 1. Wire the detector bases according to Field Wiring Diagrams. 2. Use the dip switches (SECTION 11) t

FAQs

Which detector heads are compatible with Detector Bases PAD100-IB, PAD100-RB, and PAD100-SB?

Compatible heads include photoelectric smoke detectors (PAD200-PD, PAD100-PD), photoelectric smoke/heat detectors (PAD200-PHD, PAD100-PHD), photoelectric smoke/CO detectors (PAD200-PCD), and combined smoke/CO plus heat detectors (PAD200-PCHD). Heat detector PAD100-HD and carbon monoxide detector PAD100-CD are also listed.

How does NFPA SLC Class B, A, and X wiring differ for these bases?

For Class B, use SLC wiring with designated S+ and S- terminals to the FACP loop. For Class A, two separate conductors return from the last detector base to a compatible FACP. For Class X, PAD100-IB Addressable Isolator Bases are required.

What steps are required to set addresses and install the detector head on the base?

Set address(es) for each detector head using the dip switches (1–127), noting that the PAD100 bases obtain the address from the detector head and each detector/head must have individual address(es). To install, match the detector head to the base using the alignment feature and twist clockwise until it snaps into place, then apply power to the FACP and test per the manual.
