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).

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.
