length using Table 1. Otherwise, trim the end of the tube protruding
through the duct so that 1
″
to 2
″
of the tube extend outside the duct.
Plug this end with the end cap and tape closed any holes in the pro-
truding section of the tube. Be sure to seal the duct where the tube
protrudes.
NOTE:
The sampling tube end cap is critical to the proper operation of the
duct smoke detectors. The end cap is needed to create the proper air flow
to the sensor of the duct smoke detector.

duct widths:

[4.2] Installation For Ducts More Than 8 Feet Wide
NOTE:
To install sampling tubes in ducts more than 8 feet wide, work
must be performed inside the air duct. Sampling of air in ducts
wider than 8 feet is accomplished by using the ST-10 sampling
tube. If the tube is shorter than the width of the air duct, install
the end cap into the sampling tube as shown in Figure 4 and
support the end opposite the duct smoke detector.
Install the sampling tube as follows:
1. Drill a
3
⁄4
-inch hole in the duct directly opposite the hole already drilled
for the sampling tube. Make sure the hole is 1
″
to 2
″
below the inlet
hole on the opposite side of the duct to allow for moisture drainage.
2. Slide the sampling tube with the flange into the housing bushing that
meets the air flow first. Position the tube so that the arrow points into
the air flow. Secure the tube flange to the housing bushing with two
#6 self-tapping screws.
3. From inside the duct, couple the other sections of the sampling tube
to the section already installed using the
1
⁄2
-inch conduit fittings sup-
plied. Make sure that the holes on both of the sampling tubes are lined
up and facing into the air flow.
4. Trim the end of the tube protruding through the duct so that 1
″
to 2
″
of
the tube extend outside the duct. Plug this end with the end cap and
tape closed any holes in the protruding section of the tube. Be sure to
seal the duct where the tube protrudes.
NOTE:
An alternate method to using the ST-10 is to use two ST-5 sam-
pling tubes. Remove the flange from one of the tubes and install
as described above. After the installation, use electrical tape to
close off some of the sampling holes so that there are a total of
10 to 12 holes spaced as evenly as possible across the width of
the duct.
NOTE:
Air currents inside the duct may cause excessive vibration,
especially when the longer sampling tubes are used. In these
cases a 3 inch floor flange (available at most plumbing supply
stores) may be used to fasten the sampling tube to the other
side of the duct. When using the flange/connector mounting
technique, drill a 1-inch to 1
1
⁄4
-inch hole where the flange will
be used.
[5] Install The Filters
To install the sampling tube filters, simply push the filters into the sam-
pling and exhaust tube holes, as shown in Figure 6. If a metal sampling
tube is used, install the filters over the tube end.

[9.2.2] Alarm Tests
[9.2.2.1] M02-04-00 Magnet Test
1. Place the painted surface of the magnet onto the TEST locator on the
bottom of the detector housing (Figure 14).
2. Verify system control panel alarm status and control panel execution
of all intended auxiliary functions (i.e. fan shutdown, damper control,
etc.)
3. The detector is self-restoring when the magnet is removed. Verify that
the system control panel has reset; panel may have to be reset.

[9.2.2.2] RTS451/RTS451KEY Remote Station Test
The RTS451/RTS451KEY Remote Test Station facilitates test of the alarm
capability of the duct smoke detector. These accessories provide the
stimulus to initiate an alarm condition at the detector. The detector is
self-restoring when the accessory test stimulus is removed. Verify that the
system control panel has reset; panel may need to be reset.
[9.2.3] Sensitivity Tests
Notify the proper authorities that the smoke detector system is undergo-
ing maintenance, and that the system will temporarily be out of service.
Disable the device or system undergoing maintenance to prevent unwant-
ed alarms and possible dispatch of the fire department.
[9.3] Maintenance of Duct Smoke Detectors
[9.3.1] Air Filters
1. Turn off power to the system.
2. Remove and inspect sampling tube filters.
3. If filters are heavily coated with dirt, replace them with new filters
(p/n F36-09-11). If they are not heavily coated, use a vacuum cleaner
or compressed air nozzle to remove dust, then reinstall the filters.
