FEATURES
•Addressing: DS Series detectors feature electronic addressing. No addressing switches are
used.
•LEDs: DS Series detectors use an LED to indicate the detector’s condition. In normal con-
dition, a flashing green LED indicates that the control panel is performing back-
ground supervision and a flashing red LED indicates an alarm condition.
•Sensitivity:The alarm sensitivity is the minimum obscuration level at which the detector initiates
an alarm condition and can be specified via the control unit menus or the remote
configuration software. The control unit to which these detectors are connected is
capable of interrogating each detector to determine its sensitivity.The table below
lists the acceptable smoke and heat ranges of sensitivity for the DS-PS and DS-
HFS detectors:
•Protocol: DS Series detectors operate on a Kidde Fire Systems fire alarm-suppression
control unit (Kidde, Fenwal and Chemetron brands) employing SmartOne®
communications protocol and can be mixed in any order with SmartOne legacy
detectors.
SPACING AND LOCATION
This section discusses the parameters for the spacing and location of DS Series smoke and heat
detectors. To better understand the requirements, use the following definitions:
Beams — are solid structures that project down from the ceiling surface more than 4 in. (100 mm) and are
spaced at intervals of more than 36 in. (910 mm), center-to-center.
Ceiling — is the upper surface of a space, regardless of the height. Consider a ceiling:
• Smooth, if it is uninterrupted by continuous projections, such as solid joists, beams, or ducts that ex-
tend more than 4 in. (100 mm) below the ceiling surface.
• Level, if it has a slope of less than or equal to 1 in 8.
• Sloping, if it has a slope of more than 1 in 8.
• Sloping peaked-type, if the ceiling slopes in two directions from the highest point. Consider curved or
domed ceilings as a peaked ceiling, with the slope figured as the slope of the chord from highest to
lowest point. .
• Sloping shed-type, if the high point is at one side with the slope extending toward the opposite side..
Ceiling Height — is the height from the floor to the ceiling of a room or space.
Design spacing — the spacing required for a particular installation.
Listed spacing — the spacing for which a heat detector is rated.
Partitions — walls extending from the floor toward the ceiling. If they are within 15% of the ceiling,
consider the space separated by the partitions as separate rooms.
Solid joists — are solid structures that project down from the ceiling surface more than 4 in. (100 mm)
and are spaced at intervals of 36 in. (910 mm) or less, center-to-center. Consider solid joists equivalent to
beams for smoke detector spacing guidelines.

HEAT DETECTOR SPACING

K-76-1000 -10- July 2016
HEAT DETECTOR SPACING
Do not install heat detectors in areas with an ambient temperature above 100.4° F (38°C). When
determining detector placement, consider ceiling height, construction, and ventilation as these affect a
detector’s performance.
A heat detector’s listed spacing rating is based on detector installation on a flat smooth ceiling that is 10
ft. (3 m) high. The spot-type listed spacing equates detector operation with the opening of a standard
sprinkler head within 2 minutes (±10 seconds) located 10 ft. (3 m) from the same fire.
Detector spacing is shown in Figure 1 below.
Figure 1. Listed Spacing for DS-HFS Heat Detector
Detector coverage is typically represented as a square because most structures have flat sidewalls. Actual
detector coverage is a circle whose radius is 0.7 times the listed spacing.
The listed spacing for DS-HFS heat detectors is S = 50 ft. (15.2 m).

Figure 2 below shows that the square areas of coverage, A, B, and C, are all within the detector's circle of
coverage.
Figure 2. Heat Detector’s Circle of Coverage
Since all of the area within the detector’s circle of coverage is suitable for detecting a fire, the shape and
dimensions of the detector coverage “square” in Figure 3 may be modified. Note that, although the
coverage “square” is now a “rectangle,” the coverage area remains within the overall detector circle of
coverage.

When installed on the ceiling, locate the heat detectors a minimum of 4 in. (100 mm) from the wall. When
installed on walls, locate the detector between 4 in. (100 mm) and 12 in. (300 mm) from the ceiling, as
shown in Figure 4.

Ceiling Height and Construction
Make spacing adjustments when installing DS-HFS heat detectors on other than flat smooth ceilings or at
ceiling heights 10 ft. (3 m) to 30 ft. (9.1 m) high. The table below shows the reduction in spacing required
when mounting the DS-HFS detector on ceilings higher than 10 ft. (3 m). This reduced spacing yields the
equivalent response of detectors located on a 10 ft. (3 m) ceiling. Evaluate ceilings above 30 feet carefully
with consideration to the best placement and spacing.
Sloping Peaked-Typed Ceilings
In rooms with sloping peaked-typed ceilings (refer to Figure 5), place the first row of DS-HFS detectors
within 36 in. (910 mm) horizontally of the peak, but not closer than 4 in. (100 mm) vertically to the peak.
Space additional DS-HFS detectors, if required, based upon the horizontal projection of the ceiling and
ceiling construction. For a ceiling slope of:
• Less than 30 degrees, space the detectors using the height at the peak.
• Greater than 30 degrees, space the detectors, other than those located in the peak, based on the av-
erage slope height or the height of the peak.

Sloping Shed-Typed Ceilings
In rooms with sloped ceilings having a slope greater than 1 ft. in 8 ft. (1 m in 8 m), place the first row of
detectors within 36 in. (910 mm) of the high end of the ceiling, but not closer than 4 in. (100 mm) from the
adjoining wall or ceiling. (Refer to Figure 6 below.) Space additional detectors, if required, based upon the
horizontal projection of the ceiling and ceiling construction.
If the slope is:
• Less than 7.2° (1 in 8), treat the ceiling as a level ceiling
• Less than 30°, adjust the horizontal spacing according to the height of the peak
Greater than 30°, adjust the horizontal spacing according to the average sloped ceiling height or to the
height of the peak. This spacing modification for sloped shed-typed ceilings is identical for spot-type heat
detectors and smoke detectors.

Solid Joists
When spacing heat detectors at right angles to the solid joists, do not exceed 50-percent of the listed
spacing and mount the detectors at the bottom of the joists.

Exposed Beams
Exposed beams may impede the flow of fixed temperature heat detectors. Beams are defined as solid
structures extending 4 in. (100 mm) or more down from the ceiling. Beam spacing depends on the depth
of projection from the ceiling and the center-to-center spacing between the beams.

If the beams project:
• Less than or equal to 4 in. (100 mm) below the ceiling, mount the detector on the ceiling with normal
ceiling spacing. See Figure 9, item 1.
• More than 4 in. (100 mm) below the ceiling, mount the detector on the ceiling. Do not exceed 66% of
the listed spacing at right angles to the beam direction. Treat the spacing in the direction parallel to
the beams separately. See Figure 9, item 2.
• Less than 12 in. (300 mm) in depth and are spaced less than 96 in. (2.44 m) on center, mount the
detectors on the bottom of the beams. See Figure 9, item 3.
• Greater than 18 in. (460 mm) below the ceiling and are more than 96 in. (2.44m) on center, treat each
bay created by the beams as a separate area. See Figure 9, item 4.

SMOKE DETECTOR SPACING

K-76-1000 -18- July 2016
SMOKE DETECTOR SPACING
The DS-PS spot-type smoke detector spacing recommendation of 30 ft. (9.1 m) ±5% or 18 in. (460 mm)
is based upon the detector installation on a smooth ceiling that is 10 ft. (3 m) high. Detector coverage is
typically represented as a square, because most structures have flat sidewalls. Like spot-type heat
detectors, smoke detector coverage is a circle whose radius is 0.7 times the listed spacing. Since all of
the area within the detector’s circle of coverage is suitable for detecting smoke from fire, the shape and
dimensions of the detector coverage “square” may be modified. Note that, although the coverage “square”
is a “rectangle,” the coverage area is within the overall detector circle coverage. (Refer to Figure 3.)
Note: Unlike heat detectors, smoke detectors are not given a listed spacing. It is recommended that
smoke detectors be installed on S = 30 ft. (9.1 m) ±5% or 18 in. (460 mm) installed on “x” centers,
on smooth ceilings. NFPA 72, National Fire Alarm and Signaling Code contains additional infor-
mation regarding spacing adjustments.
Ceilings and Walls
Locate smoke detectors on the ceiling or, if on a sidewall, between the ceiling and 12 in. (300 mm) down
from the ceiling to the top of the detector.
Figure 10. DS-PS Smoke Detector Placement Near Ceiling/Wall Joints
For a smooth ceiling, for every point on the ceiling, locate the detector within a horizontal measurement
no greater than 0.7 times the selected spacing.
