Air Duct Detectors
INTRODUCTION
C ERBERUS PYROTRONICSTM Model AD-3XRI and AD-3XRILP
Detectors are System IXL (ICON-1), System XL3, and MXL Control Panel
com atible air duct detectors with an auxiliary relay. They are designed
for use in heating, ventilating, and air conditioning duct systems. Model
AD-3XRI uses ionization smoke detectors, and Model AD-3XRILP uses
hotoelectric smoke detectors to detect the resence of combustion
roducts in a duct system. (Refer to TECHNICAL DATA below for infor-
mation on com atible detectors.)
When smoke or combustion roducts are detected, shutdown of the duct
system and/or o eration of su lementary equi ment is rovided by the
related system control anel.

OPERATION
When the AD-3XRI/3XRILP (AD-3XRI or AD-3XRILP) is o erating, a
sam le of air is drawn from the duct and assed through the sam ling
chamber at low velocity by means of the inlet sam ling tube. The air
sam le asses through the smoke detector mounted in the duct housing
and is exhausted back into the duct through the outlet sam ling tube.
Alarm Indication
The XL3, IXL, and MXL Control Panels have LEDs for alarm indication
that are used with the AD-3XRI/3XRILP. Refer to Table 3 above.
The LED on the detector in alarm can also be turned on or off by system
command.
Alarm Condition
When used with the XL3, IXL, or MXL Control Panel, the Model AD-3XRI/
3XRILP o erates directly from the control anel. An alarm condition on
either 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
o tional rinters used. On MXL Control Panels the alarm is indicated on
the MKB-1/-2 and on any o tional rinters used.
After a fire is extinguished, and all roducts of combustion are cleared
from the duct system, each system can be reset at its res ective control
anel, and the XL3 also can be reset at its o tional rinter, if available.
Trouble Condition
A trouble condition from an AD-3XRI/3XRILP is indicated by visual and
audible system devices connected to the control anel in an XL3, IXL, or
MXL Control Panel, de ending on the ty e of system in which it occurs.
It can also be indicated by an o tional rinter. Call your Authorized
Siemens Building Technologies, Inc. Service Re resentative when a
trouble occurs.

MOUNTING THE AIR DUCT HOUSING
Location on Duct System
Locate the air duct detector in the main su ly duct, downstream from the
filters and ositioned so as to o erate reliably in case of smoke in any
art of the air stream. In instances where filters are ca able of removing
smoke, install detectors both u stream and downstream from the filters.

4
The air duct detectors use sam ling tubes which monitor the full width of
an air duct to overcome the limitations of s ot-ty e 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 ossible, 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 de-
tector to ermit checking and cleaning of the sam ling tubes, if necessary.
Locate the air duct detector in the air handling system, as shown in Figure
2 and in conformance with NFPA Pam hlet No. 90A, Air Co ditio i g

a d Ve tilati g System and with NFPA 72 National Fire Alarm Code.
(Both ublications are available from the National Fire Protection Associa-
tion, Batterymarch Park, Quincy, Massachusetts.) The detector on the
return air side of the blower should be located at a oint rior to exhaust-
ing air from the building or diluting return air with outside air. The detector
on the su ly air side of the blower should be downstream of the blower.
Wire or rogram the detectors into the system so that they automatically shut
down the blowers and o erate dam ers as required.
Mounting of t e 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 u with the
sam ling tube hole on the sam ling chamber and the smaller hole
lines u with the housing mounting hole.
b. Affix the adhesive backed tem late (5) to the side of the ductwork.
c. Drill the four 0.110 diameter holes with a No. 35 drill bit and cut or
unch out two 7/8-inch diameter holes as indicated on the tem late.
d. Attach the a ro riate model housing to the air duct using two No. 10
11/2 inch 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
housing to ermit checking and cleaning of the sam ling tubes. The
access hole must be covered and sealed when not in use.
Sampling Tube Selection
To ensure accurate air sam ling, there are four standard lengths of inlet
sam ling tubes to choose from. To select the a ro riate length, deter-
mine the outside width of the duct. Select the sam ling tube nearest to,
but greater than, the duct width (Table 5). The outlet sam ling tube for all
ducts is a fixed length of 4 inches (10.1 cm). Trim the inlet sam ling tube
at the job site as described below.

Trimming t e Inlet Sampling Tube (See Figure 4)
a. Measure the outside width of the duct.
b. Add 2.25 inches to obtain ro er length of tube.
Exam le: Outside width of duct 2 ft 6 in
Add 2.25 inches + 2.25 in
Length of sam ling tube 2 ft 8.25 in
The length (2 ft 8.25 in) determines (Table 5 on age 5) the
model number of the a ro riate sam ling tube (STA-3).
c. Measure the sam ling tube, starting from the end with the four mount-
ing holes.
d. Trim tube to the correct length, remove all burrs, and insert a rubber
sto er (Figure 3, Item 9) in the tube.
Installation of t e Sampling Tubes
a. Before installing the tubes, cut a 7/8-inch hole in the duct wall that is
directly o osite the inlet sam ling chamber hole in the detector hous-
ing. This will allow the inlet tube to rotrude through the duct.
b. Attach brackets (10) to the inlet and outlet air sam ling tubes with 3/16
screws (11).
NOTE: Whe attachi g brackets, be sure to alig tubes properly
(See Figure 4).

c. Install the inlet tube (3) by inserting it through the air sam ling chamber
as shown in Figure 3. Face sam ling 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 u er socket of the air
sam ling 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 sam ling holes extend beyond the ductway, that the
sto er (9) remains firmly in osition, and that the duct hole is sealed
around the rotruding sam ling tube.
Air Duct Sampling Tube Pressure Measurement
The CERBERUS PYROTRONICSTM Model PDM-3 Pressure Differential
Measuring device should be used to ensure that the sam ling tube ressure
differential is within the s ecified limits (See TECHNICAL DATA). Qualified
ersonnel should take measurements in accordance with the PDM-3
I structio s, P/N 315-085535.
ELECTRICAL WIRING
System XL3 - See Figure 6. Use two wire circuits of 18 AWG, limited
energy, shielded cable without conduit, if ermitted by the local building
codes.
MXL Co trol Pa el - See Figure 7. Use two wire circuits of 18 AWG,
limited energy, shielded cable without conduit, if ermitted by the local
building codes.
IXL System (ICON-1) - See Figure 7. Use two wire circuits of 18 AWG,
limited energy, shielded cable, without conduit if it is ermitted by the
local building codes.
Control of Normally Energized and De-Energized Devices
The Model AD-3XRI/3XRILP can be wired for direct relay control of normally
energized and de-energized devices as follows (Refer to Figure 5).
a. Wire normally energized devices (fans, blowers, etc.) to the NC contacts
between terminals 9 and 10 in order to shut down these devices on alarm.
Figure 5
Connections for Control of Normally Energized and De-Energized Devices
NOTES:
1. All relay contacts shown repre-
sent the condition they are in just
after a reset pulse - the normal
supervisory, no alarm condition.
2. If the alarm relay contacts on the
relay board are being used to
control 120 AC operated equip-
ment, ensure that earth ground
is properly connected to the
internal ground strap, using the
proper conduit lock nuts.
Failure to provide proper
grounding may result in fatal electrical
shock and causes
non-conformance with national
and local codes.

b. Wire normally de-energized devices (extinguishing smoke removal fan,
etc.) to the NO contacts between terminals 10 and 11 in order to acti-
vate these devices on alarm.
NOTE: Relay contacts may not be in su ervisory condition when
shi ed.
