SILENT KNIGHT SD505-DUCT User manual

II. MOUNTING THE DETECTOR
The sampling tubes may be ordered to a desired length or
ordered in one of 3 standard lengths and cut per requirements.
The intake sampling tube consists of a piece of steel piping with
a series of holes drilled the entire length of the tube and should
extend the entire width of the duct. The holes must be facing
into the air flow (see Figure 2). The exhaust tube consists of a
piece of steel piping approximately 7-1/2" long.
1. Remove paper backing from mounting template AP 121 (packaged in installation kit) and
affix to duct at desired location.
2. Using template as a guide, drill 4 mounting holes (3/32" diameter) for duct mounting
screws (4 #12 x 1/2" sheet metal screws packaged in installation kit). Drill or punch holes
for sampling tubes in air ducts (1-3/8" diameter), using template as a guide. Clean all holes.
Duct Smoke Detector Location
Requirements: To prevent false alarms the detectors should
not be mounted in areas of extreme high or low temperatures,
in areas where high humidity exist, or in areas where duct air
may contain gases or excess dust. The duct detector should,
when possible, be located a minimum of six duct widths
downstream from a source of turbulence (bends, inlets, or
deflection plates). At these locations, air flow is less turbulent
and the air/smoke mixture should be more homogenous.
Refer to NFPA 90A, 72, and 101 for more information. See
Figure 1A and 1B.
Exception: Where it is physically impossible to locate
the duct detector accordingly, the duct detector can be
positioned closer than six duct widths, but as far as
possible from inlets, bends, or deflection plates.
These are Installation Instructions (DWG.# HA-06-094) for the Duct Housing customized as follows:
SD505-DUCT Duct Housing with the SD505-APS Analog Photoelectric Smoke Sensor*
SD505-DUCTR Duct Housing with the SD505-APS Analog Photoelectric Smoke Sensor & Relays*

INSTALLATION INSTRUCTIONS FOR THE
DUCT SMOKE DETECTOR
A. DUCT PREPARATION
C. SAMPLING TUBE ASSEMBLY (See Figure 2)
The Duct Detectors are designed for use in ducts where the air velocities are
from 300 to 4000 feet per minute. Verify this by checking specifications of
installation and if necessary, use an Alnor Model 6000P velocity meter (or
equivalent) to check the air velocity. See Figure 2 for sampling tube
orientation to air flow direction.
B. VERIFY AIR FLOW AND DIRECTION
FIGURE 1B: DUCT HOUSING MOUNTING
TOP OF DUCT HOUSING
To verify proper sampling of air, use a Dwyer Model 4000 differential pressure gauge (or equivalent). See Figure 3 for
gauge connections. The pressure differential between input sampling tube and exhaust tube should be greater than
0.01" of water and less than 1.2" of water.
E. MOUNT THE DUCT HOUSING(See Figure 1B & 2)
Move duct housing/sampling tube assembly to desired location. Use 4 mounting screws (4 #12 x 1/2" sheet metal screws,
packaged in installation kit) to secure the housing to the air duct.
1. Sampling tube connectors are equipped with set screws, which allow the tubes to be mounted only in directions shown in
Figure 2. Establish proper orientation considering airflow direction.
2. Insert intake and exhaust tubes into connectors, align set screw to set screw hole in tubes andtighten firmly.
1. Cut the intake sampling tube to the desired length.
2. Firmly insert the stopper (packaged in installation kit) in the end of the INTAKE sampling tube.

by Honeywell

1. With power source de-energized and the smoke detector not installed, wire
all connections per engineering drawings. Refer to the applicable figures below
depending on your duct housing model number.
2. With all wiring in place, install the detector head.
3. Energize the duct detector.
Wiring must conform to applicable local codes, ordinances and regulations
covering these types of devices. Wire the detectors according to the
engineering drawings for the particular job requirements. These detectors
are not intended for open area protection, nor should they be used for
open air protection. Refer to NFPA 90A and NFPA 72 for general and
additional information on Duct Smoke Detectors concerning operation
and installation. Terminals are suitable for up to #14 gauge wire.
