NOTICE
THIS DEVICE IS A STAND ALONE DUCT DETECTOR. IT IS DESIGNED
TO SAMPLE THE AIR FLOW PASSING BY IT IN THE AIR DUCT TO
DETERMINE WHETHER IT CONTAINS UNACCEPTABLE LEVELS OF
SMOKE.
THE EFFECTIVENESS OF A STAND ALONE DUCT DETECTOR IS
HIGHLY DEPENDENT UPON:
•THE DESIGN AND OPERATING CONDITIONS OF THE AIR HANDLING
SYSTEM IN WHICH IT IS INSTALLED;
•VARIABLES SUCH AS SMOKE DILUTION AND STRATIFICATION OVER
WHICH EVEN THE BEST DESIGNED SYSTEMS HAVE NO CONTROL;
AND,
•PROPER PLACEMENT AND POSITIONING OF THE STAND ALONE
DUCT DETECTOR, WHICH IS OFTEN COMPROMISED FOR
PRACTICAL REASONS.
FOR THE REASONS STATED ABOVE, THE EFFECTIVENESS OF THE
STAND ALONE DUCT DETECTOR CANNOT BE WARRANTEED OR
GUARANTEED. UNDER NO CIRCUMSTANCES SHOULD THIS STAND
ALONE DUCT DETECTOR BE USED AS OR REGARDED TO BE A
SUBSTITUTE FOR THE BUILDING’S REGULAR FIRE ALARM AND
DETECTION SYSTEM.
THE NFPA STATES THAT DUCT SMOKE DETECTORS MUST NOT BE
USED AS SUBSTITUTES FOR OPEN AREA PROTECTION. DO NOT
CONNECT THE STAND ALONE DUCT DETECTOR TO A FIRE ALARM
CONTROL PANEL. THIS UNIT IS INTENDED AS A STAND ALONE DEVICE
FOR USE IN THE CONTROL OF AIR HANDLING EQUIPMENT FOR THE
PURPOSES OF CLOSING DAMPERS OR SHUTTING DOWN AIR
HANDLING UNITS.

The 4098-9687 Stand Alone Duct Detector (see Figure 1 on page 2) is designed
to sample air and detect smoke in air ducts. The 4098-9687 duct detector uses
the 4098-9601 photoelectric smoke detector.
The 4098-9687 Stand Alone Duct Detector provides fail-safe operation, the loss
of power or detector removal activates the Duct Detector Housing alarm relay
contacts.
The 4098-9842 Duct Control Station (see page 6 for details) is the remote
control interface connected to the Stand Alone Duct Detector and provides a
Power-On LED, Alarm LED, audible sounder, sounder silence switch, and
detector Test/Reset switch.
For detailed information on using smoke detectors in air distribution systems, see
NFPA 90A and refer to the following excerpt from NFPA 90A.
Per NFPA 90A, 1999 Edition
Section 4-4.4.3 Where smoke detectors required by Section 4-4 are installed in
a building not equipped with an approved fire alarm system as
specified by 4-4.4.2, the following shall occur:
1. Smoke detector activation required by Section 4-4 shall cause a visual and
audible signal in a normally occupied area.
2. Smoke detector trouble conditions shall be indicated visually or audibly in a
normally occupied area and shall be identified as air duct detector trouble.

Note: Two 3/4" conduit entries are provided for field wiring
connections (#12-18 AWG) to the PCB assembly. The
unused conduit entry is sealed off using the cap plug
(ship group 748-518). Apply even pressure on the
plastic cap plug to secure it against the conduit plate.
The cap plug seals and removes easily with moderate
pressure.

The 4098-9687 Stand Alone Duct Detector can be powered from 24 VDC, 24 VAC, or
120 VAC power sources. Separate terminal block connections are available for the
24 VDC/VAC or the 120 VAC power sources. When the 120 VAC connection is used,
no connections should be made to the 24 VDC/VAC inputs.
Note:The power sources must originate from a fused power supply listed for fire
protection signaling use, or from the Fire Alarm Control Panel (FACP) power
supply.
