[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 D35PL Air Dust Stroke Detector utilizes photoelectric technology for the detection of smoke. This detection method, when combined with an electric housing design, samples air passing through the dust and allows detection of a developing hazardous occasion. When sufficient smoke is secured, an alarm signal is imitated in. The fire control panel excelling the detector, and appropriate action can be taken to shut off fans, blowers, change over air handling systems, etc. These actions can facilitate the management of noise smoke and fire gases throughout the areas served by the dust system.
The D355PI incorporates a sensor cover temper feature that provides a trouble signal at the pixel immediately if the cover is removed or improperly installed. Proper installation of the sensor cover removes the trouble condition.
It programmed with the system control panel, two 120s on each duct smoke detector light to provide local visible indication.
the USSAL provides a remote alarm output for use with auxiliary devices, such as the RA400Z/RA100Z remote LED concentrator, as well as remote test capacity with the RT9451/151 or RTS651KEY/RTS151KEY Remote Test Station

Model D355PL detectors are designed to be used in air handling systems having air velocities of 100 to 4000 feet per minute. The widths from 6 inches in 12 feet can be accommodated. Be sure to check engineering specifications to ensure that the air velocity in the duct links within these parameters. If necessary, use a velocity meter (anemometer) to check the air velocity in the duct.
[4.2]DETERMINE MOUNTING LOCATION AND CONFIGURATION
On coats wider than 18 inches it is recommended that the detector be mounted downstream of a head, abstraction in the chest, or the supply or return air inlet.

Drill pilot holes at target "A" centers and cut two 1.375 inch diameter holes using a 15-inch hole saw or pump. Drill, 155 inch diameter holes using a 750 inch drill at target "C" centers, if desired, drill an additional 156 inch hole at the location of one of the mounting holes on the lower housing.
[4.4] SECURE THE DUCT DETECTOR TO THE DUCT
Use two [rectangular configuration] or three [square configuration] of the provided sheet metal screws to screw the duct detector in the duct. CAUTION: Du and contribution by water
LEISAMBLING TUBE INSTALLATION
15. USAMPLING 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 sampling tube length must exceed at least f_0 across the duct width for optimal performance.
The sampling tube is always installed with the air inlet holes facing into the air flow. To solve proper filtration, the tube's connection 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 descent housing in a vertical orientation is acceptable provided that the air flows directly into the sampling 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.

FIGURE 3. AIR DUCT DETECTOR SAMPLING TUBE:

1281-0
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 to be installed if exceeded. Install into the housing connection that is downstream from the sampling tube connection. The exhaust tube can be installed from the front of the detector in the back. A longer 1 fuel exhaust tube, model FTP, is available as an accessory to cases where the molded exhaust tube does not exceed at least 2 inches into the duct.
[5.2] SAMPLING TUBE INSTALLATION
-
Per tubes shower than the width of the duct slide the sampling tube, with installed end cap, into the housing connection that meets the air flow field. Position the tube so that the snow points into the airflow as shown in Figure 3. Per NIPA sampling tubes over 3 feet long should be supposed at the next opposite side of the duct detector. In ducts work than 6 feet, work must be performed inside the outlet to couple the other section of the sampling tube in the section clearly installed using the -inch constant spring supplied. Make sure that the holes on both sections or the air inlet sampling tube are tied up and facing into the airflow.
-
For tubes longer than the width of the duct, the tube should extend out of the opposite side of the duct. Drill a 94 inch holes in the duct up pretise the hole already out for the sampling tube. Figure 3 that the sampling tube is supplied downward from the duct smoke detector to allow for motere drainage away from the detector. The sampling tube should be angle at least 95° downward for every 10° of duct with put Figure 4. There should be 10 to 13 holes spaced as evenly as possible across the width of the duct. If there are more than a hole in the section of the recording section of the duct, or a scorsal tube using Table 1. Check the gauge tube to leave approximately 1 in inches excluding outside the duct. Plug the cord with the end ep and tape closed any hooks in the protruding section of the tube, it sure to seal the duct where the tube protrudes.
FIGURE 4

[5.4]REMOTE SAMPLING TUBE INSTALLATION
The detector arrangement can also incorporate the remote mounting or 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 housing shall be verified to be between 0.01 and 1.11 inches of water. Do so by measuring the pressure difference between the inner and outlet ports on the detector housing using a manometer as described in the Measurement Tests section of this manual.
[5]MEASUREMENT TESTS
[6.1] AIR FLOW
The DS55FG is designed to operate over an extended air speed range of 100 to 4000 FPM. To verify sufficient sampling of elected air, run the air handler on and use a monometer to measure the differential pressure between the two sampling tubes. The differential pressure should measure at least 0.61 inches of water and be more than 1.11 inches of water. Because most commercially available meters cannot accurately measure very low pressure differentials, applied once with less than 500 FPM of duct air speed may require one of the following: (1) the use of a current-counseling pressure transmitters (Prayer Series 867) or (2) the use of aerosol smoke, see far below for vast descriptions.
FIGURE 5. PROCEDURE FOR VERIFYING AIR FLOW:
![Fire-Lite D355PL - [6.1] AIR FLOW - 1](/content/2026/05/1041508/images/5ea881a3c52f47e154de471968648991cbfa0baa75ee3749b1a2beb60edf8b92.jpg)
1016-01
[6.2]LOW FLOW AIR FLOW TEST USING DWYER SERIES 607 DIFTERENTIAL PRESSURE TRANSMITTER
Verify the all speed of the duct, using an accommodate. Air speed must be at least 100 FPM. Weize the Dryer transmitter as shown in Figure 5. Connect the loads of the motor to other side of the 100Omega resistor. Allow lift to warm up for 12 seconds: "Well; Both HCC1 and LOW pressure sets open to ambient air, moisture and record" The voltage drop across the 100Omega detector (meas, comments 1), 4.0 volts in typical. Using Fibeste tubing and rubber stoppers, connect the HCC2 axis, of the transmitter to the gaugling tubes, of the duct device or lower heating, and the LOW mode of the transmitter to the exhaust tube of the high voltage drop. The voltage drop against the 100Omega detector measurement 21, subtract the voltage recorded in measurement 1 from the voltage recidual in measurement 2. If the difference is greater than 0.15 volts, there is enough air flow through the duct smoke detector for project operation.
[7] MIELD 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 accessories, which should be rated coded to prevent wiring matches. Improper conduction can prevent a system from applying properly in the event of a line. For signal wiring (the wiring between detectors or from detector to auxiliary devices), it is usually carried under that single conductor who be no smaller than 19 gauge. The duct smoke detector terminals accommodate wire sizes up to 12 gauge. Flexible conduct is recommended for the last foot of conduct; avoid conduct connections may be used if desired.
Then 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 knot

[8.4]DUCT SMOKE DETECTOR TEST & MAINTENANCE PROCEDURES
Test and maintain duct smoke detectors as recommended in MPA 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 loss to prevent unwanted alarms.
[8.4.1]TEST THE UNIT
-
302-04-00 Magnet Test (not included). This sensor can be functionally tested with a test magnet. The test magnet electrocically simulates smoke in the sensing chamber, testing the sensor electronics and connections to the control panel.
-
Remote Test Accessory - The use of a remote accessory for visible indication of power and alarm is recommended.
Verely system control panel alarm status and control panel execution of all interested 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 block, latch on, or latch off. Refer to the control panel technical documentation 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]SMOVE 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, we are conventional measureter in measuring differential pressure between the sampling tubes, as described under measurement Tests on Page 3.
Drill 2.5 inch hole: 1 feet upstream from the duct smoke detector. With the air handler on, measure the air velocity with an anemonomer. Air speed must be at least 100 FPM. Spray acrosal smoke' into the duct through the 1/2 inch hole for five seconds. Wait some results for the duct smoke detector in alarm. If the duct smoke detector alarms, air is flowing through the detector. Remove the duct smoke detector cover and blow out the residual acrosal smoke from the chamber and reset the duct smoke detector at the panel. Use duct tape to set the acrosal smoke entry hole. Remember to replace the cover after the test or the detector will not function properly.
Dacemed smoke can be purchased from Home Safety and Industries at Home-safeguard.com, model 255 Smoke Detector Tester, and Ciekkit Smoke Detector Tester model: CHER02 and CHER06 available from SFI. When used properly, the caused smoke agent will cause the smoke detector to go into alarm. See to the manufacturer's published instructions for proper use of the cannot smoke agents.
CAUTION
Canned account simulated smoke (canned smoke agent) formulas will vary by manufacturer. Mouse or averse to these products may have long term adverse effects on the smoke detector. Consult the canned smoke agent manufacturer's published instructions for any further warnings or caution statements.
