The SuperDuct four-wire controller coupled with a compatible sensor
make up a SuperDuct four-wire duct smoke detector. The sensor
sends an alarm signal to the controller when smoke is detected in the
HVAC system. Upon receipt of the alarm signal, the controller takes
the appropriate actions to provide early warning of the impending fire
and prevent smoke from circulating throughout the building. The
controller can be configured for a range of operating voltages and
supports one or two compatible sensors.
WARNING: SuperDuct duct smoke detectors are not intended as a
substitute for open area protection.
The controller comprises a plastic housing, a printed circuit board, and
a clear plastic cover. The clear plastic cover is secured to the housing
with a single captive screw for easy access to the wiring terminals.
Knockouts are provided to route wires into the controller housing.
The controller contains no user serviceable parts.

Run all field wiring through the knockouts located on the bottom of the
controller housing. Maintain a 1/4-inch separation between powerlimited and nonpower-limited wiring at all times.
Installation instructions
Please read these instructions thoroughly before installing. In addition
to this document, important information can be found in Technical
Bulletin P/N 3100685.
Step 1: Mount the controller
Mount the controller on a flat section of HVAC duct or sheet metal as
shown in Figure 1 using the sheet metal screws provided in the
hardware kit. The controller does not have to be mounted next to the
sensor.

Jumper configuration
Set the controller configuration jumpers as described below.
Note: Failure to remove JP1 prevents the controller from indicating a
trouble condition with the sensor connected to J2. It does not prevent
the controller from responding to an alarm signal.

Notes
• If strain relief is required, secure the cable using the cable clamps
provided with the cable kit
• If you are connecting the controller to two sensors, remove JP1
Field wiring
Bring all field wiring into the controller through the knockouts on the
bottom of the housing as shown in Figure 6. Keep all power-limited
wiring in the shaded area and all nonpower-limited wiring in the area
that is not shaded.
Remove the terminal block cover and connect the field wiring as shown
in Figure 8. Replace the terminal block cover when finished.
Note: Maintain a 1/4-inch separation between power-limited and
nonpower-limited wiring at all times.
Testing
After completing the installation, test the controller to ensure that it is
operating correctly before leaving the site. For details, refer to
Technical Bulletin P/N 3100685.

Notes
[1] Remove JP1 when the controller is connected to two
sensors
[2] Alarm initiation contacts shown in normal condition. Contacts
close on alarm.
[3] Supervision relay contacts shown in normal condition.
Contacts change over on sensor or controller trouble.
[4] Install end-of-line resistor on last controller only. EOLR value
determined by fire alarm control panel.
[5] Move JP3 to the 230V position only when using 220V or
240V to operate the controller
[6] No more than two remote test/reset stations can be
connected to the same controller. Wiring is nonsupervised.
Maximum wire resistance is 10 ohms per wire.
[7] Control panel provides supervision and determines wire
requirements
[8] Wiring is nonsupervised. Wire resistance from first controller
to last controller can not exceed 5 ohms.15 controllers, max.
[9] Wiring is supervised by the controller. Maximum wire
distance is 15 ft.
[10] TSD-C02 module has not been performance evaluated to
UL 2075 or approved by ULC
[11] Only required when using a remote test/reset station and
the controller is wired to a fire alarm control panel. Otherwise,
use the supervision relay contacts as shown on Controller B.
