CAUTION: These air duct detectors are designed for detection and con-
trol of products of combustion in a duct system. They are not
to be used for open area protection.
OPERATION
When the AD-3I/3ILP (AD-3I or AD-3ILP) is operating, a sample of air is
drawn from the duct and passed through the sampling chamber at low ve-
locity by means of the inlet sampling tube. The air sample passes through
the smoke detector mounted in the duct housing and is exhausted back
into the duct through the outlet sampling tube.
Alarm Indication
The System 3, System SXL-EX, System SXL, System XL3, MXL/MXL-IQ
Control Panel, and System PXL all have LEDs for alarm indication that are
used with theAD-3I/3ILP.
Alarm Condition
When used with the CP-2ER, MXL/MXL-IQ Control Panel, System PXL,
System SXL-EX, System SXL, System 3, or System XL3, the ModelAD-3I/
3ILP operates directly from the control panel.An alarm condition on any of
these systems is indicated by visual and audible system devices. On XL3
Systems the alarm is also indicated on the DAX module and any optional
printers used. On MXL Systems the alarm is indicated on the Control Panel
display and on the optional printer. See system manuals for further infor-
mation.
After a fire is extinguished, and all products of combustion are cleared from
the duct system, each system can be reset at its respective control panel,
or remote annunciator, if available.
Trouble Condition
A trouble condition from an AD-3I/3ILP is indicated by visual and audible
devices on the control panel in the CP-2ER, System 3, System SXL-EX,
System SXL, System XL3, MXL/MXL-IQ Control Panel, or System PXL,
depending on the type of system in which it occurs. On System XL3 and
MXL/MXL-IQ Control Panels it also may be indicated by an optional printer.

MOUNTING THE AIR DUCT HOUSING
Location on Duct System
Locate the air duct detector in the main supply duct, downstream from the
filters and positioned so as to operate reliably in case of smoke in any part
of the air stream. In instances where filters are capable of removing
smoke, install detectors both upstream and downstream from the filters.
The air duct detectors use sampling tubes which monitor the full width of an
air duct to overcome the limitations of spot-type smoke and heat detectors
in the duct. However, since stratification can occur in the air stream after a
long duct run, locate the detector after bends or inlets which create turbu-
lence, and hence, a more homogeneous mixture of air. The detector should,
when possible, be located a minimum of six duct-widths downstream from the
source of the turbulence (See Figure 1). A 12 inch by 12 inch access hole
should be cut in the duct adjacent to the detector to permit checking and
cleaning of the sampling tubes, if necessary.

DUCT WIDTHS
Locate the air duct detector in the air handling system, as shown in Figure
2 and in conformance with NFPA Pamphlet No. 90A, Air Conditioning
and Ventilating System and with NFPA 72 National FireAlarm Code.
(Both publications are available from the National Fire ProtectionAssocia-
tion, Batterymarch Park, Quincy, Massachusetts.) The detector on the
return air side of the blower should be located at a point prior to exhaust-
ing air from the building or diluting return air with outside air. The detector
on the supply air side of the blower should be downstream of the blower.
Wire or program the detectors into the system so that they automatically shut
down the blowers and operate dampers as required in the event of an alarm.

Figure 2
Recommended Locations in Duct Systems
Mounting of the Air Duct Housing (See Figure 3)
a. Affix the adhesive backed gaskets (Item 1) to the back of the detector
housing (2) so that the larger hole on the gasket lines up with the sam-
pling tube hole on the sampling chamber and the smaller hole lines up
with the housing mounting hole.
b. Affix the adhesive backed template (5) to the side of the ductwork.
c. Drill the four 0.110 diameter holes with a No. 35 drill bit and cut or
punch out two 7/8-inch diameter holes as indicated on the template.
d. Attach the appropriate model housing to the air duct using two No. 10
11/2inch screws (6) and also using two No. 10 1-inch screws (7) with
lockwashers (8).
e. Cut a 12 inch by 12 inch access hole in the duct adjacent to the hous-
ing to permit checking and cleaning of the sampling tubes. The access
hole must be covered and sealed when not in use.

Sampling Tube Selection
There are four standard lengths of inlet sampling tubes. To ensure accurate
air sampling, select the appropriate length and determine the outside width of
the duct. Select the sampling tube nearest to, but greater than, the duct width
(Table 5). The outlet sampling tube for all ducts is a fixed length of 4 inches
(10.1 cm). Trim the inlet sampling tube at the job site as described below.
TABLE 5
SAMPLING TUBE SELECTION CHART
Sampling Tube Standard
Outside Duct Width Model No. Tube Length
1 ft 93/4in or less STA-2 2 ft
1 ft 93/4in - 3 ft 33/4in STA-3 3 ft 6 in
3 ft 33/4in - 6 ft 33/4in or less STA-6 6 ft 6 in
6 ft 33/4in - 9 ft 93/4in or less STA-10 10 ft
Greater than 9 ft 93/4in Consult factory
Note: Each model is manufactured with a different number and size of
sampling hole. Only the specific tube must be used for the specified
duct width.
Figure 4
Sampling Tube Orientation

Trimming the Inlet Sampling Tube (See Figure 4)
a. Measure the outside width of the duct.
b. Add 2.25 inches to obtain proper length of tube.
Example: Outside width of duct 2 ft 6 in
Add 2.25 inches + 2.25 in
Length of sampling tube 2 ft 8.25 in
The length (2 ft 8.25 in) determines (Table 5 on page 7)
the model number of the appropriate sampling tube (STA-3).
c. Measure the sampling tube, starting from the end with the four mounting
holes.
d. Trim tube to the correct length, remove all burrs, and insert a rubber
stopper (Figure 3, Item 9) in the tube.
Installation of the Sampling Tubes
a. Before installing the tubes, cut a 7/8-inch hole in the duct wall that is
directly opposite the inlet sampling chamber hole in the detector hous-
ing. This will allow the inlet tube to protrude through the duct.
b. Attach brackets (10) to the inlet and outlet air sampling tubes with 3/16
screws (11).
NOTE: When attaching brackets, be sure to align tubes properly
(See Figure 4).
c. Install the inlet tube (3) by inserting it through the air sampling chamber
as shown in Figure 3. Face sampling tube holes into the air stream
(Figure 4), and secure to the housing with 8/32 screws (12).
d. Install the outlet tube (4) by inserting it into the upper socket of the air
sampling chamber with the scarfed end facing downstream (See Figure
4). Secure the bracket to the housing with an 8/32 screw.
e. Make sure no sampling holes extend beyond the ductway, that the stop-
per (9) remains firmly in position, and that the duct hole is sealed around
the protruding sampling tube.
Air Duct Sampling Tube Pressure Measurement
The Model PDM-3 Pressure Differential Measuring device should be used
to ensure that the sampling tube pressure differential is within the specified
limits (See TECHNICAL DATA). Qualified personnel should take measure-
ments in accordance with the PDM-3 Instructions, P/N 315-085535.
