4,000 feet per minute (0.5 to
20.32 m/sec.).
• Patented telescopic sampling
tube.
Description
• Easily accessible code wheels
for addressing detector.
• Outside mounting tabs.
• Mounts to round or rectangular
ducts from 1’ to 12’ (0.3 to 3.7
meters) wide.
• Transparent cover for conve-
nient visual inspection.
The
Gamewell SS-PD
and
SS-PDR
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
SS-PDR
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
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 SmartScan
TM
protocol. The SS-
PDR additionally incorporates a relay.

Applications
Duct smoke detectors have specific limitations, they are:
•
NOT
a substitute for open area smoke detectors.
•
NOT
a substitute for early warning detection.
•
NOT
a replacement for a building’s regular fire detection system.

of Smoke Detectors in Duct Applications,

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.
