[4]Contents Of The Duct Smoke Detector Kit

1. Complete housing base and cover assembly

2. Two #10 machine screws for mounting

3. Two sampling tube filters

4. One test magnet

5. Drilling template

6. Two foam gaskets

7. Four #6-self tapping mounting screws for the metal sampling tube and optional exhaust tube extension

8. Two jack nuts

9. One inlet tube end plug

10. Metal sampling tube end plug

11. One telescoping sampling tube

12. One #8 self-tapping screw for the telescoping sampling tube NOTE: For ducts over 11/2 feet, longer inlet sampling tubes must be ordered to complete the installation. They must be the correct length for the width of the duct where they will be installed. See Table 1 on page 3 to determine the inlet tube required for different

duct widths.

[5]Installation Sequence

[5.1] Verify Duct Air Flow Direction And Velocity

Model DH100 detectors are designed to be used in air han- dling systems having air velocities of 500 to 4000 feet per minute. Be sure to check engineering specifications to en- sure that the air velocity in the duct falls within these pa- rameters. If necessary, use a velocity meter to check the air velocity in the duct.

[5.2] 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. Center punch holes A and B. Drill the

holes as indicated on the template. Insert the two jack nut receptacles. Drive a #10 machine screw into the jacknut to flare the retainer and then back the screw out to use for de- tector mounting.

[5.2.1] Sampling Tube Installation for Ducts Less Than 11/2 Feet Wide (see Figure 2)

1.Remove the front cover.

2.Use the tube installation chart above to determine the set screw setting.

3.Slide the sampling tube into the housing bushing.

4.Align the holes in the bushing with the holes in the sam- pling tube. Make sure the number of holes exposed on

the supplemental tube matches the number as deter- mined in step 2. Secure with the #8 self-tapping screw into the bottom hole of the permanent tube.

NOTE: For ducts greater than 11/2 feet in width, refer to sections [5.4.1] and [5.4.2].
