System Sensor PERTRONIC DNRW User manual

[2] GENERAL DESCRIPTION
Smoke introduced into this air duct system will be distributed throughout the
entire building. Smoke detectors designed for use in air duct systems are used
to sense the presence of smoke in the duct.
Model DNRW Air Duct Smoke Detector uses photoelectric technology for the
detection of smoke. This detection method, when combined with an efficient
housing design, samples air passing through the duct and allows detection of
a developing hazardous condition. When sufficient smoke is sensed, an alarm
signal is initiated at the fire control panel monitoring the detector, and appro-
priate action can be taken to shut off fans, blowers, change over air handling
systems, etc. These actions can facilitate the management of toxic smoke and
fire gases throughout the areas served by the duct system.
The DNRW incorporates a sensor cover tamper feature that provides a trou-
ble signal at the panel immediately if the cover is removed or improperly in-
stalled. Proper installation of the sensor cover removes the trouble condition.
When programmed with the system control panel, two LEDs on each duct
smoke detector light to provide local visible indication.
The DNRW provides a remote alarm output for use with auxiliary devices, such
as the RA100Z remote LED annunciator, as well as remote test capability with
the RTS151 or RTS151KEY Remote Test Stations.

BEFORE INSTALLING
Read System Sensor’s Applications Guide for Duct Smoke Detectors (HVAG53),
which provides detailed information on detector spacing, placement,
zoning, wiring, and special applications. This manual is available online at
www.systemsensor.com. NFPA Standards 72 and 90A should also be refer-
enced for detailed information.
NOTICE: This manual shall be left with the owner/user of this equipment.
IMPORTANT: The detector must be tested and maintained regularly following
NFPA 72 requirements. According to NFPA, the detector should be visually
inspected semiannually and functionally tested at least once a year. This may
need to be more frequent depending on the air quality of the duct supply air.
[1] LIMITATIONS OF DUCT SMOKE DETECTORS
WARNING
The National Fire Protection Association has established that DUCT DETEC-
TORS MUST NOT BE USED AS A SUBSTITUTE FOR OPEN AREA DETECTOR
PROTECTION as a means of providing life safety. Nor are they a substitute for
early warning in a building’s regular fire detection system.
System Sensor supports this position and strongly recommends that the user
read NFPA Standards 90A, 72, and 101. The DNRW Air Duct Smoke Detectors
are listed per UL 268A.
This device will not operate without electrical power. Fire situations may
cause an interruption of power. The system safeguards should be discussed
with your local fire protection specialist.
This device will not sense smoke unless the ventilation system is operating
and the cover is installed.
For this detector to function properly, it MUST be installed according to the
instructions in this manual. Furthermore, the detector MUST be operated within
ALL electrical and environmental specifications listed in this manual and the
sensor head installation manual. Failure to comply with these requirements
may prevent the detector from activating when smoke is present in the air duct.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

[4] DETECTOR INSTALLATION
[4.1] VERIFY DUCT AIR FLOW DIRECTION AND VELOCITY
Model DNRW detectors are designed to be used in air handling systems hav-
ing air velocities of 100 to 4000 feet per minute. Duct widths from 6 inches to
12 feet can be accommodated. Be sure to check engineering specifications to
ensure that the air velocity in the duct falls within these parameters. If neces-
sary, use a velocity meter (anemometer) to check the air velocity in the duct.
[4.2] DETERMINE MOUNTING LOCATION AND CONFIGURATION
On ducts wider than 18 inches it is recommended that the detector be
mounted downstream of a bend, obstruction in the duct, or the supply or
return air inlet.
Exception: Installation of duct detectors can be on or within a commercial
packaged rooftop heating and air-conditioning system, fire/smoke dampers
and economizers. They may be mounted in either the supply and/or return air
section as determined by local code.
Once a suitable location is selected, determine if the detector is to be mounted
in a side-by-side “rectangular” configuration or a top-over-bottom “square”
configuration as shown in Figure 2. If mounting in the square configuration,
remove the rear attachment screw, rotate the unit at hinge, and replace the
screw into the new attachment hole as shown in Figure 2. Do NOT remove
the hinge screw during this process. Final installation approval shall be
based upon passing differential pressure and smoke entry tests described in
Section 6 Measurement Tests.

[4.3] DRILL THE MOUNTING HOLES
Remove the paper backing from the mounting template supplied. Affix the
template to the duct at the desired mounting location. Make sure the template
lies flat and smooth on the duct.
[4.3.1] FOR RECTANGULAR SIDE-BY-SIDE MOUNTING CONFIGURATION
Center punch at four target centers: two “A” for sampling tubes and two “B”
for the rectangular configuration mounting tabs as shown on mounting tem-
plate. Drill pilot holes at target “A” centers and cut two 1.375 inch diameter
holes using a 13⁄8-inch hole saw or punch. Drill .156 inch diameter holes using
a 5⁄32 inch drill at target “B” centers.
[4.3.2] FOR SQUARE TOP-OVER-BOTTOM MOUNTING CONFIGURATION
Center punch at four target centers: two “A” for sampling tubes and two “C”
for the square configuration mounting tabs as shown on mounting template.
Drill pilot holes at target “A” centers and cut two 1.375 inch diameter holes
using a 13⁄8-inch hole saw or punch. Drill .156 inch diameter holes using a 5⁄32
inch drill at target “C” centers. If desired, drill an additional .156 inch hole at
the location of one of the mounting tabs on the lower housing.
[4.4] SECURE THE DUCT DETECTOR TO THE DUCT
Use two (rectangular configuration) or three (square configuration) of the pro-
vided sheet metal screws to screw the duct detector to the duct.
CAUTION: Do not overtighten the screws.
[5] SAMPLING TUBE INSTALLATION
[5.1] SAMPLING TUBE SELECTION
The sampling tube must be purchased separately. Order the correct length, as
specified in Table 1, for width of the duct where it will be installed. The sam-
pling tube length must extend at least 5/8across the duct width for optimal
performance.
The sampling tube is always installed with the air inlet holes facing into the
air flow. To assist proper installation, the tube’s connector is marked with an
arrow. Make sure the sampling tube is mounted so that the arrow points into
the airflow as shown in Figure 3. Mounting the detector housing in a vertical
orientation is acceptable provided that the air flows directly into the sam-
pling tube holes as indicated in Figure 3. The sampling tube and exhaust tube
can be mounted in either housing connection as long as the exhaust tube is
mounted downstream from the sampling tube.

H0551-00
CAUTION: The sampling tube end cap, included with the detector, is critical
to proper operation of the duct smoke detector. The end cap is needed to
create the proper air flow to the sensor of the duct smoke detector. Once any
sampling tube length adjustments are made, plug the end of the sampling
tube with the provided end cap.
A plastic exhaust tube is included with the unit. Install into the housing con-
nection that is downstream from the sampling tube connection. The exhaust
tube can be installed from the front of the detector or the back. A longer 1
foot exhaust tube, model ETX, is available as an accessory in cases where the
molded exhaust tube does not extend at least 2 inches into the duct.
[5.2] SAMPLING TUBE INSTALLATION
1. For tubes shorter than the width of the duct, slide the sampling tube,
with installed end cap, into the housing connection that meets the air-
flow first. Position the tube so that the arrow points into the airflow as
shown in Figure 3. Per NFPA sampling tubes over 3 feet long should be
supported at the end opposite of the duct detector. In ducts wider than 8
feet, work must be performed inside the duct to couple the other section
of the sampling tube to the section already installed using the ½ inch
conduit fitting supplied. Make sure that the holes on both sections of the
air inlet sampling tube are lined up and facing into the airflow.
2. For tubes longer than the width of the air duct, the tube should extend
out of the opposite side of the duct. Drill a ¾ inch hole in the duct op-
posite the hole already cut for the sampling tube. Ensure that the sam-
pling tube is angled downward from the duct smoke detector to allow for
moisture drainage away from the detector. The sampling tube should be
angled at least 1⁄4” downward for every 12” of duct width per Figure 4.
There should be 10 to 12 holes spaced as evenly as possible across the
width of the duct. If there are more than 2 holes in the section of the tube
extending out of the duct, select a shorter tube using Table 1. Otherwise,
trim the tube to leave approximately 1 to 2 inches extending outside the
duct. Plug the 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: 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 sam-
pling tube to the other side of the duct. When using the flange/connector
mounting technique, drill a 1 to 1 ¼ inch hole where the flange will be used
[5.3] MODIFICATIONS OF SAMPLING TUBES
There may be applications where duct widths are not what is specified for the
installation. In such cases, it is permissible to modify a sampling tube that is
longer than necessary to span the duct width.
Use a 0.193-inch diameter (#10) drill and add the appropriate number of holes
so that the total number of holes exposed to the air flow in the duct is 10 to 12.
Space the additional holes as evenly as possible over the length of the tube.
CAUTION: This procedure should only be used as a temporary fix. It is not
intended as a permanent substitute for ordering the correct length tubes.
[5.4] REMOTE SAMPLING TUBE INSTALLATION
The detector arrangement can also incorporate the remote mounting of the
sampling tube and/or exhaust tube. In this case both the detector, sampling
tube and exhaust tube (if included) should be rigidly mounted to withstand
the pressure and vibrations caused by the air velocity. The location of the
detector’s sampling tube should be such that there is uniform airflow in the
cross section area.
Pressure differential across the sampling and exhaust ports in the detector hous-
ing shall be verified to be between 0.01 and 1.11 inches of water. Do so by mea-
suring the pressure difference between the inlet and outlet ports on the detector
housing using a manometer as described in Section 6 Measurement Tests.
[6] MEASUREMENT TESTS
[6.1] AIR FLOW
The DNRW is designed to operate over an extended air speed range of 100 to
4000 FPM. To verify sufficient sampling of ducted air, turn the air handler on
and use a manometer to measure the differential pressure between the two
sampling tubes. The differential pressure should measure at least 0.01 inches
of water and no more than 1.11 inches of water. Because most commercially
available manometers cannot accurately measure very low pressure differen-
tials, applications with less than 500 FPM of duct air speed may require one
of the following: 1) the use of a current-sourcing pressure transmitter (Dwyer
Series 607) or 2) the use of aerosol smoke, see below for test descriptions.

[6.2] LOW FLOW AIR FLOW TEST USING DWYER SERIES 607
DIFFERENTIAL PRESSURE TRANSMITTER
Verify the air speed of the duct using an anemometer. Air speed must be at
least 100 FPM. Wire the Dwyer transmitter as shown in Figure 5. Connect the
leads of the meter to either side of the 1000Ωresistor. Allow unit to warm up
for 15 seconds. With both HIGH and LOW pressure ports open to ambient air,
measure and record the voltage drop across the 1000Ωresistor (measurement
1), 4.00 volts is typical. Using flexible tubing and rubber stoppers, connect the
HIGH side of the transmitter to the sampling tube of the duct smoke detec-
tor housing, and the LOW side of the transmitter to the exhaust tube of the
duct smoke detector housing. Measure and record the voltage drop across the
1000Ωresistor (measurement 2). Subtract the voltage recorded in measure-
ment 1 from the voltage recorded in measurement 2. If the difference is greater
than 0.15 volts, there is enough air flow through the duct smoke detector for
proper operation.

[7] FIELD WIRING; INSTALLATION GUIDELINES
All wiring must be installed in compliance with the National Electrical Code
and the local codes having jurisdiction. Proper wire gauges should be used.
The conductors used to connect smoke detectors to control panels and acces-
sory devices should be color-coded to prevent wiring mistakes. Improper con-
nections can prevent a system from responding properly in the event of a fire.
For signal wiring (the wiring between detectors or from detector to auxiliary
devices), it is usually recommended that single conductor wire be no smaller
than 18 gauge. The duct smoke detector terminals accommodate wire sizes up
to 12 gauge. Flexible conduit is recommended for the last foot of conduit; solid
conduit connections may be used if desired.
Duct smoke detectors and alarm system control panels have specifications for
Signaling Line Circuit (SLC) wiring. Consult the control panel manufacturer’s
specifications for wiring requirements before wiring the detector loop.
[7.1] WIRING INSTRUCTIONS
Disconnect power from the communication line before installing the DNRW
duct smoke detector.
The DNRW detectors are designed for easy wiring. The housing provides a ter-
minal strip with clamping plates. Wiring connections are made by sliding the
bare end under the plate, and tightening the clamping plate screw. See Figure
6on below for system wiring.

[8] VERIFICATION OF OPERATION
[8.1] INSTALL THE COVER
Install the covers making sure that the cover fits into the base groove. Tighten
the seven screws that are captured in the covers. Note that the cover must be
properly installed for proper operation of the sensor.
[8.2] POWER THE UNIT
Activate the communication line on terminals COM + and COM –.
[8.3] DETECTOR CHECK
Standby – If programmed by the system control panel, look for the presence of
the flashing LEDs through the transparent housing cover. The LED will flash
with each communication.
Trouble – If programmed by the system control panel and the detector LEDs
do not flash, then the detector lacks power (check wiring, missing or improp-
erly placed cover, panel programming, or power supply), the sensor head is
missing (replace), or the unit is defective (return for repair).
[8.4] DUCT SMOKE DETECTOR TEST & MAINTENANCE PROCEDURES
Test and maintain duct smoke detectors as recommended in NFPA 72. The
tests contained in this manual were devised to assist maintenance personnel
in verification of proper detector operation.
Before conducting these tests, notify the proper authorities that the smoke
detection system will be temporarily out of service. Disable the zone or system
under test to prevent unwanted alarms.
[8.4.1] TEST THE UNIT
1. M02-04-00 Magnet Test (not included) – This sensor can be functionally
tested with a test magnet. The test magnet electronically simulates smoke
in the sensing chamber, testing the sensor electronics and connections to
the control panel.
2. Remote Test Accessory – The use of a remote accessory for visible indica-
tion of power and alarm is recommended.
Verify system control panel alarm status and control panel execution of
all intended auxiliary functions (i.e. fan shutdown, damper control, etc.).
Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs
to blink, latch on, or latch off. Refer to the control panel technical docu-
mentation for sensor LED operation and expected delay to alarm.
[8.4.2] THE DETECTOR MUST BE RESET BY THE SYSTEM CONTROL PANEL
[8.4.3] SMOKE ENTRY TEST USING AEROSOL SMOKE
This test is intended for low-flow systems (100-500 FPM). If the air speed is
greater than 500 FPM, use a conventional manometer to measure differential
pressure between the sampling tubes, as described in Section 6 Measurement
Tests.
Drill a ¼-inch hole 3 feet upstream from the duct smoke detector. With the air
handler on, measure the air velocity with an anemometer. Air speed must be
at least 100 FPM. Spray aerosol smoke* into the duct through the ¼-inch hole
for five seconds. Wait two minutes for the duct smoke detector to alarm. If the
duct smoke detector alarms, air is flowing through the detector. Remove the
duct smoke detector cover and blow out the residual aerosol smoke from the
chamber and reset the duct smoke detector at the panel. Use duct tape to seal
the aerosol smoke entry hole. Remember to replace the cover after the test or
the detector will not function properly.
Additionally, canned aerosol simulated smoke (canned smoke agent) may be
used for smoke entry testing of the smoke detector. Tested and approved aero-
sol smoke products are:

No Climb TESTIFIRE 2000
CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary
by manufacturer. Misuse or overuse to these products may have long term
adverse effects on the smoke detector. Consult the canned smoke agent manu-
facturer’s published instructions for any further warnings or caution state-
ments.
