1. Description
This document provides instructions for mounting and wiring the detector bases
PAD100-LFSB and PAD100-SPKB. The following detectors are compatible with
detector bases PAD100-LFSB and PAD100-SPKB.
PAD100-PD:
Photoelectric Smoke Detector
PAD100-PHD:
Photoelectric Smoke / Heat Detector
PAD100-HD:
Heat Detector
PAD100-CD:
Carbon Monoxide Detector
2a. Field Wiring Diagram for PAD100-LFSB
Typical field wiring diagrams for the Signaling Line Circuit (SLC) (FIGURE 1). The
SLC supports NFPA wiring Class B, A and X. (FIGURE 1) Typical of NFPA Class B SLC
(S+, S-) Wiring using the PAD100-LFSB base. In Class A arrangement two separate
conductors would return from the last detector base to a listed compatible Fire
Alarm Control Panel (FACP).
Class X Wiring (FIGURE 2), requires use of PAD100-IM (Addressable Isolator
Module). The typical field diagram is in Field Wiring Diagram(s) for PAD100-IM.
The PAD100-IM manual can be obtained at www.pottersignal.com
2b. Field Wiring Diagram for PAD100-SPKB
Typical field wiring diagrams for the Signaling Line Circuit (SLC) (FIGURE 4). The
SLC supports NFPA wiring Class B, A and X. The PAD100-SPKB offer a choice of
field selectable power taps: 1/8, 1/4, 1/2, 1, 2 and 4 watts (FIGURE 5) for use
with either 25 VRMs or 70.7 VRMs audio amplifiers. The frequency range of the
PAD100-SPKB is 400-4000 Hz. The PAD100-SPKB is suitable for line supervision.
The PAD100-SPKB includes DC blocking capacitor which allows for supervision
voltage of either polarity.
3. 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-SPKB / PAD100-LFSB base, 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.
DO NOT USE LOOPED WIRE UNDER TERMINALS. BREAK WIRE RUN TO
PROVIDE SUPERVISION OF CONNECTION.
CAUTION!
Break wire runs to provide supervision for connections made to each wire pair.
When installing, route field wiring away from sharp projections, corners and
internal components.
Detector Base Mounting
PAD100-LFSB / PAD100-SPKB should be mounted directly on the electrical box
(FIGURE 6a) or to the LFSBBB-W back box (FIGURE 6b). The PAD100-LFSB /
PAD100-SPKB mounting holes are configured for a 4” x 2-1/8” deep square box.
Use a box for each base and run the power circuit to all base locations.
Use 12 to 18 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) to set address(es) (1 - 127) for each
detector head.
NOTICE:
THE PAD100-LFSB /PAD100-SPKB OBTAINS THE ADDRESS FROM THE
DETECTOR HEAD.
THE DETECTORS AND THE PAD100 MODULES MUST HAVE INDIVIDUAL
ADDRESS(ES).
3. To install the detector head onto the base, match the detector heads to the
base using the alignment feature and twist clockwise until the detector heads
snap into place (FIGURE 6a).
