DUCT SMOKE DETECTOR
SL-2000 SERIES
DESCRIPTION
The SL-2000 Series Duct Smoke Detectors provide
early detection of smoke and combustion products pre-
sent in air moving through HVAC ducts. Air sampling is
accomplished by intake sampling tubes, which are
ordered separately. A standard length exhaust tube is
provided with each detector. These devices are designed
to prevent the recirculation of smoke in areas by the air
handling systems, fans, and blowers. Complete systems
may be shut down in the event of smoke detection.
OPERATION
The SL-2000 Series is designed to operate in duct
widths from 12.0" to 10.0' (30.5 cm to 3.05m) with an air
velocity from 100-4000 fpm (0.5-20.3 mps). The
SL-2000 Series will operate on any one of four input
voltages: 24 VAC, 24 VDC, 115 VAC, or 230 VAC. It
uses either a photoelectric or ionization smoke detector
head. Each detector contains two Form C and one Form
A alarm contact, which transfer in the event of smoke.
There is also one trouble contact, which supervises the
presence of input power and removal of the detector
head. A manual test/reset switch and visual indicators of
pilot and alarm are provided on the front of the detector.
Up to 30 SL-2000 Series units may be wired to use a
common test/reset function and to alarm simultaneously
when a single unit alarms.

ORDERING INFORMATION
WIRING INTERCONNECTING WIRING
Mount the detector in an air duct using the provided template and
sheet metal screws. Detector should be mounted at least six
duct widths from the fan or other sources of turbulence with air-
flow from 100-4000 fpm (0.5-20.3 mps). The intake sampling
tube has holes drilled the entire length of the tube and should
extend the entire width of the duct, with the end opposite the
detector capped. The holes must be facing into the air flow (see
Figure 1 to the right). The exhaust tube is a piece of steel piping
approximately 7"Long (17.8 cm).
Intake Sampling Tube Lengths
Model Duct Width
STN-2.5 1.0' to 2.5' (0.3 to 0.7m)
STN-5.0 2.5' to 5.0' (0.7 to 1.5m)
STN-10.0 5.0' to 10.0' (1.5 to 3m)
Important
For the correct installation, testing and maintenance of a duct
smoke detector, follow the instructions provided with the detec-
tor and refer to your locally enforced fire, mechanical, and/or
building codes. Please also review NFPA 72 (National Fire
Alarm Code) and NFPA 90A (Standard for Installation of Air
Condition and Ventilation Systems). Your local Authority Having
Jurisdiction (AHJ) should also be consulted.
Note: Sampling tubes over 3' (0.9m) must be supported on the
opposite side of the duct from the detector.
FIGURE 1. TYPICAL DUCT INSTALLATION
CAUTION: For terminals (7, 8, 18), (6, 16, 17), (13, 14) do not
use looped wire under terminals. Break wire run to provide
supervision of connections. NOTE: When using detector interconnection functions, wire all
detectors to a common power source. Use of multiple power sources
for interconnected detectors may cause damage to the detectors
and/or may prevent the detectors from functioning properly.
