One #8 self-tapping screw for the plastic sampling tubeNOTE: For ducts over 1 1 ⁄2 feet, longer inlet sampling tubesmust be ordered to complete the installation. Theymust be the correct length for the width of the ductwhere they will be installed. See Table 1 on page 3to determine the inlet tube required for differentduct widths.[5] Installation Sequence[5.1] Verify Duct Air Flow Direction And VelocityModel DH100ACDCLP detectors are designed to be used inair handling systems having air velocities of 100 to 4000feet per minute. Be sure to check engineering specificationsto ensure that the air velocity in the duct falls within theseparameters. If necessary, use a velocity meter (anemometer)to check the air velocity in the duct.[5.2] Drill The Mounting HolesRemove the paper backing from the mounting templatesupplied. Affix the template to the duct at the desiredmounting location. Make sure the template lies flat andsmooth on the duct. Center punch holes A and B. Drill theholes as indicated on the template. Insert the two jack nutreceptacles. Drive a #10 machine screw into jacket to flarethe retainer, then back out the screw to use for detectormounting.[5.2.1] Sampling Tube Installation for Ducts LessThan 1 1 ⁄2 Feet Wide (see Figure 2)1. Remove the front cover.2. Slide the plastic sampling tube into the housing bushing.3. Align the holes in the bushing with the holes in the samplingtube. Make sure there are 6 exposed holes on theplastic sampling tube. Secure with the #8 self-tappingscrew into the bottom of the permanent tube (shown inFig. 2).NOTE: For ducts greater than 1 1 ⁄2 feet in width, refer tosections [5.4.1] and [5.4.2].Figure 2.

Figure 3. Installation of foam gaskets over samplingtube bushings:SCREW HOLES FORATTACHING HOUSINGTO DUCT WORK.A78-2045-00[5.4] Sampling Tube Installation for Ducts GreaterThan 1 1 ⁄2 Feet WideThe sampling tube is identified by a series of air inlet holeson the tube. A plastic tube is included for ducts up to 18″in width. All other lengths must be purchased separately.Order the correct length, as specified in Table 1, for widthof the duct where it will be installed. The exhaust tube ismolded onto the base of the duct housing, and theA2440-00 Exhaust Tube Extension is available as an accessoryin those cases where the molded exhaust port does notextend at least 2 inches into the duct.The inlet tube is always installed with the air inlet holesfacing into the air flow. To assist proper installation, thetube’s mounting flange is marked with arrows. Make surethe inlet tube is mounted so that the arrows point into theair flow (see Figure 4). Figure 5 shows the various combinationsof tube mounting configurations with respect to airflow. Mounting the detector housing in a vertical orientationis acceptable, provided that the air flows directly intothe sampling tube holes as indicated in Figure 4.Table 1. Inlet tubes required for different ductwidths:Outside Duct Width Inlet Tube Required1 to 2 ft. ST-1.52 to 4 ft. ST-34 to 8 ft. ST-58 to 12 ft. ST-102. Slide the tube into the housing bushing that meets theair flow first. Position the tube so that the arrows pointinto the air flow.3. Secure the tube flange to the housing bushing with two#6 self-tapping screws.4. For tubes longer than the width of the air duct, the tubeshould extend out of the opposite side of the duct. Ifthere are more than 2 holes in the section of the tubeextending out of the duct, select a different length usingTable 1. Otherwise, trim the end of the tube protrudingthrough the duct so that 1″ to 2″ of the tube extend outsidethe duct. Plug this end with the end plug and tapeclosed any holes in the protruding section of the tube. Besure to seal the duct where the tube protrudes.Figure 4.

If the tube is longer than the width of the air duct, drill a3/4″ hole in the duct opposite the hole already cut for theinlet tube. Make sure the hole is 1″ to 2″ below the inlethole on the opposite side of the duct to allow moisturedrainage away from the detector. If the tube is shorterthan the width of the air duct, install the end plug into theinlet tube as shown in Figure 4. Sampling tubes over 3 ft.long must be supported at the end opposite the ductsmoke detector.VERTICAL MOUNTING OF HOUSINGNOTE: Only metal sampling tubes may be used on orientationsC and D.[5.4.2] Installation For Ducts More Than 8 Feet WideNOTE: To install inlet tubes in ducts more than 8 feet wide,work must be performed inside the air duct.Sampling of air in ducts wider than 8 feet is accomplishedby using the ST-10 inlet sampling tube. If thetube is shorter than the width of the air duct, installthe end plug into the inlet tube as shown in Figure4 and support the end opposite the duct smokedetector.D200-14-00 3 I56-0084-00
