Installation Instructions
This sheet is intended to be used to install the
SD505-6RB to a Silent Knight Addressable
control panel. Refer to the control panel
installation manual for programming
instructions (P/N 151139 or 151209).
The SD505-6RB adds a relay output function to
a Silent Knight addressable detector. The Form
C relay is rated at 8.0 amps for 240 VAC, 120
VAC and 30 VDC applications.

Wiring
This section contains information on how to
wire the SD505-6RB to the SLC Loop of the
control panel, how to wire the SD505-6RB to the
6” detector base, and wiring guide lines for each.
Figure 1 illustrates how to run the wiring for the
SLC loop and relay through the extension base,
and how wiring harness 140675 connects to the
6” detector base.

SLC Wiring
The SD505-6RB can be configured for either
Class A (Style 6) or Class B (Style 4)
supervision.
Class A (Style 6)
Figure 2 illustrates how to wire the SD505-6RB
to the SLC loop connectors for Class A (Style 6)
supervision.

Power Limited
Note: Low and high voltage wiring must be run through
separate openings on the extension base. See
Figure 1. If you are connecting both power limited
and non-power limited sources to the relay base,
you must use one of the following types of wire,
FPLP, FPLR, or FPL within the box in accordance
to NEC 760.54.

Mounting the SD505-6RB
Do Not over tighten screws.
Figure 4: Mounting the SD505-6RB
The SD505-6RB mounts on a standard single or
double gang electrical switch box.
Follow these steps to mount the SD505-6RB:
1. Mount the extension base using the #8 1-1/2
screws through the extension base mounting
holes. (See Figure 4.)
2. Wire the SLC loop as shown in Figure 2 or
Figure 3.
3. Snap the SD505-6RB cover plate over the
SD505-6RB circuit board. See Figure 1.
4. Connect wiring harness (P/N 140675) to the
smoke base as shown in Figure 1.
5. Plug wiring harness (P/N 140675) into
harness connector. Refer to Figure 1.
6. Attach the smoke base (P/N SD505-6AB) to
extension base (P/N 120505) using the
#8 1/2” screws. (See Figure 4.)
