    OVERVIEW OF DS SERIES ADDRESSABLE SMOKE AND HEAT DETECTORS DS Series smoke and heat detectors are intelligent analog addressable devices which make alarm decisions based on the information collected by their sensors. The detectors are constructed of a high- impact polymer. Each detector features an optional base-locking tab The following detectors and bases are available: 1.
  • Page 9 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.

  • Page 12 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.
  • Page 13 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”...
  • Page 14 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.
  • Page 15 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.
  • Page 16 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.
  • Page 17 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. > 4 in. (100 mm) D. Depth 1. Ceiling 3.
  • Page 18 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.

  • Page 20 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.
  • Page 21 Beams and Solid Joists For smoke detector spacing, solid joists are considered equivalent to beams. For ceilings with a beam or solid joist depth less than 10 percent of the ceiling height (0.1 H), mount the detectors on the bottom of beams. For ceilings with a beam or solid joist depth equal to or greater than 10 percent of the ceiling height (0.1 H) and a beam spacing equal to or greater than 40 percent of the ceiling height (0.4 H), locate the detectors on the ceiling in each beam pocket.
  • Page 22 Sloping Ceilings with Beams For sloping ceilings with beams running parallel up the slope: • Locate the smoke detectors on the ceiling within the beam pockets. • The ceiling height is the average height over slope. • To determine the detector spacing, measure along the horizontal projection of the ceiling. •...
  • Page 23 Sloping Peaked-Typed Ceilings In rooms with sloping peaked-type ceilings, place the first row of detectors within 3 ft. (1 m) (horizontally) of the ceiling peak. Space additional detectors, if required, based upon the horizontal projection of the ceiling and ceiling construction. This modification of spacing for smoke detectors on sloped ceilings is identical to that used for spot-type heat detectors.
  • Page 24 Stratification and Spacing Compensation Stratification occurs when the upward movement of smoke and gases ceases due to the loss of buoyancy of heated smoke. Stratified air within a room may impede smoke reaching the detector. To improve detection system response in situations where stratification exists, install additional detectors at elevations below ceiling level as shown in Figure 14.
  • Page 25 Smoke Detector High Air Movement The use of spot-type smoke detectors in areas of high air movement (greater than 300 ft./min [1.5m/sec]) requires a suitable reduction in detector spacing to maintain detector performance. Use the table below to determine the reduced detector spacing in these areas. This table is not valid for use under floor or in ceiling plenum areas, however, the principle of reduced spacing in these high-velocity areas applies.

  • Page 28 According to independent studies, use heat detectors only for property protection. Never rely on heat detectors as the sole means of fire protection. WARNING Heat detectors sense change in air temperature and initiate alarm conditions based on a fixed- temperature point, rate of temperature rise, or amount of temperature rise above ambient condition. The DS-HFS heat detector is a spot-type detector.

  • Page 30 Regardless of the principle of operation, smoke detectors sense the presence of smoke particles. In order for a smoke detector to sense these particles, smoke must travel from the point of origin to the detector. When evaluating a particular building or location for detector layout, determine likely fire locations and paths of smoke travel from each of these fire locations.
