• Outside mounting tabs.
Intelligent Low-Flow Photoelectric
Smoke Duct Detectors provide low-
flow technology that enables duct
smoke detection throughout a broad
range of airflow environments in HVAC
applications. The low-flow technology
can detect smoke at air speed veloci-
ties of 100 feet per minute (0.5 m/sec.)
or greater, while continuing the same
reliable performance to 4,000 feet per
minute (20.32 m/sec.). The intelligent
low-flow duct detectors sample air cur-
rents passing through a duct and gives
dependable performance for shutdown
• Mounts to round or rectangular
ducts from 1’ to 12’ (0.3 to 3.7
meters) wide.
• Transparent cover for conve-
nient visual inspection.

Listings
Listings and approvals below
apply to the SS-PD and SS-
PDR Intelligent Low-Flow
Photoelectric Duct Smoke
Detectors. In some cases,
certain modules may not be
listed by certain approval
agencies, or listing may be in
process. Consult factory for
of fans, blowers, and air conditioning systems, preventing the spread of toxic smoke
an fire gases through the protected area.
The SS-PD and SS-PDR provide a remote alarm output for use with auxiliary
devices such as the RA400 remote LED annunciator, as well as remote test capa-
bility with the RTS451 or RTS451KEY Remote Test Stations.
The SS-PD is a photoelectric duct detector with SmartScanTM protocol. The SS-
latest listing status.
PDR additionally incorporates a relay.
• UL Listed: file S1115.
Applications
• CSFM approved:
file 3240-1288:167.
Duct smoke detectors have specific limitations, they are:
• NOT a substitute for open area smoke detectors.
• NOT a substitute for early warning detection.
• MEA approved: file 384-02-E
Vol. III.
• NOT a replacement for a building’s regular fire detection system.
Please call Gamewell for a copy of System Sensor’s application guide, Proper Use
of Smoke Detectors in Duct Applications, (A05-1004-00).
Installation
Wiring: For signal wiring (the wiring between detectors or from detectors to auxil-
iary devices), it is recommended that single conductor wire be no smaller than 18
AWG (0.75 mm²). The duct smoke detector terminals accommodate wire sizes up
to 12 AWG (3.25 mm²). Flexible conduit is recommended for the last foot (30.48
cm) of conduit; solid conduit connections may be used if desired.
Smoke detectors and alarm system control panels have specifications for Signal-
ing Line Circuit (SLC) wiring. Consult the control panel specifications for wiring
requirements before wiring the detector loop. The SS-PD and SS-PDR detectors
are designed for ease of wiring; their housing provides a terminal strip with clamp-
ing plates.
LED Features: If programmed with the system control panel, two LEDs on each
duct smoke detector light to provide local visible indication.
