INTRODUCTION
Model SA-3I and SA-11P detectors from Siemens Industry, Inc. are self-contained air duct detec-
tors designed for installation in heating, ventilating, and air conditioning duct systems. These
Detector Models SA-3I and SA-11P can use ionization or photoelectric smoke detectors to sig-
nal the presence of combustion products in a duct system. (Refer to TECHNICAL DATA for informa-
tion on compatible detectors.)
In addition to the self-contained detection features of the SA-3I and SA-11P, these air duct
detectors also can power and supervise the following configurations.
(1) two air duct detectors (Model AD-3I or AD-11P) mounted on the exterior of the duct and
employing sampling tubes to monitor the air in the duct, or
(2) two spot detectors (Model PE-11) mounted on the interior wall of the air duct, or
(3) one each of the detectors listed in (1) and (2) above.
