Plastic sampling tube connected to duct smoke detector: [1] Verify Duct Air Flow Direction And Velocity The DH200RPL duct smoke detector is designed to be used in air handling systems having air velocities of 100 to 4000 feet per minute (0.5 to 20.32m/s). Be sure to check engineering specifications to ensure that the air velocity in the duct falls within these parameters. If necessary, use a [4.1] Installation For Ducts Greater Than 11⁄2 Feet (0.46m) But velocity meter to check the air velocity in the duct. See Air Flow Test, Less Than 8 Feet (2.4m) Wide section 9.1. 1. If the tube is longer than the width of the air duct, drill a 3⁄4″ (19mm) hole in the duct opposite the hole already cut for the sampling tube.

[4.2] Installation For Ducts More Than 8 Feet (2.4m) Wide NOTE: To install sampling tubes in ducts more than 8 feet (2.4m) wide, work must be performed inside the air duct. Sampling of air in ducts wider than 8 feet (2.4m) is accomplished by using the ST-10 sampling tube. If the tube is shorter than the width of the air duct, install the end cap into the sampling tube as shown in Figure 4 and support the end opposite the duct smoke detector. Install the sampling tube as follows: 1. Drill a 3⁄4-inch (19mm) hole in the duct directly opposite the hole Table 1. Sampling tubes recommended for different duct widths: Outside Duct Width already drilled for the sampling tube. Make sure the hole is 1″ to 2″ (25 to 50mm) below the inlet hole on the opposite side of the duct to Sampling Tube Recommended* allow for moisture drainage. 1 to 2 ft.

Trim the end of the tube protruding through the duct so that 1″ to 2″ (25 to 50mm) of the tube extend outside the duct. Plug this 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. ARROW MUST FACE INTO AIR FLOW NOTE: AIR FLOW DIRECTION An alternate method to using the ST-10 is to use two ST-5 sampling tubes. Remove the flange from one of the tubes and install H0108-02 as described above. After the installation, use electrical tape to close off some of the sampling holes so that there are a total of 10 to 12 holes spaced as evenly as possible across the width of the duct.

Connect dler on and use a manometer to measure the differential pressure between the leads of the meter to either side of the 1000Ω resistor. Allow unit to the two sampling tubes. The differential pressure should measure at least warm up for 15 seconds. With both HIGH and LOW pressure ports open 0.0015 inches of water and no more than 1.2 inches of water. Because most to ambient air, measure and record the voltage drop across the 1000Ω commercially available manometers cannot accurately measure very low resistor (measurement 1), 4.00 volts is typical. Using flexible tubing and pressure differentials, applications with less than 500 FPM of duct air speed rubber stoppers, connect the HIGH side of the transmitter to the sampling may require one of the following: 1) the use of a current-sourcing pressure tube of the duct smoke detector housing, and the LOW side of the trans- transmitter (Dwyer Series 607) per Section 9.1.4 or; 2) the use of aerosol mitter to the exhaust tube of the duct smoke detector housing.

Plug the exhaust and sampling tube holes to prevent ducted air from carrying smoke away from the detector head, then blow smoke such as cigarette, cotton wick, or punk directly at the head to cause an alarm. REMEMBER TO REMOVE THE PLUGS AFTER THIS TEST, OR THE DETECTOR WILL NOT FUNCTION PROPERLY. H0163-01 [9.1.5] Filter Replacement The filters do not substantially affect smoke performance even when up to 90% of the filter is clogged. Quarterly visual inspection usually suffices to determine whether the filters should be replaced because only a high percentage of contamination affects performance. If further testing is required, compare differential pressure readings with and without the filters installed. If the difference exceeds 10% replace the filters. In no case should the pressure differential fall below 0.0015 inches of water. 1 2 COM (-) COM (+) COM (-) + COM (+) Figure 9.
