User manual SILENT KNIGHT SD505-DTS INSTALLATION

[. . . ] SD505-ADHR Duct Detector Housing With Relay Module & SD505-DTS Installation Instructions The following are instructions on how to install the SD505-ADHR & SD505-DTS to a Silent Knight Addressable control panel. Mounting Instructions Follow these steps to mount the SD505-ADHR: 1. Remove paper backing from mounting template (packaged in installation kit) and affix to duct at installation location. [. . . ] The intake sampling tube is a piece of steel piping with a series of holes drilled the entire length of the tube. The tube should be cut to a size that allows it to extend the entire width of the duct. The holes must be facing into the air flow (see Figure 1). The exhaust tube is a piece of steel piping measuring 7 inches.

Wiring Instructions This section contains information on how to connect the SD505-ADHR to a power source, to a fan motor, and to a SD505-DTS remote test station. Wiring must conform to applicable local codes, ordinances, and regulations covering this type of device. Refer to NFPA 90A and NFPA 72E for additional information on duct smoke detector operation and installation. Figure 1: Sampling Tube Orientation 5. Cut intake sampling tube to the desired length. Firmly insert the provided stopper into the end of the intake sampling tube. Standard Lengths for Intake Sampling Tubes STS-2. 5 STS-5. 0 STS-10. 0 For duct widths of 1. 0' to 2. 5' For duct widths of 2. 5' to 5. 0' For duct widths of 5. 0' to 10. 0' 7. Mount the detector by placing the detector/sampling tube assembly into position and secure to duct housing using mounting screws. Verify that air velocity is appropriate for the type of smoke detector you are using by checking specifications of installation and, if necessary, by using air velocity meter (Alnor Model 6, 000P or equivalent). Verify proper air sampling by using a differential pressure gauge (Dwyer Model 4000 or equivalent). See Figure 2 for connections. Figure 3: Wire Routing Example Important! [. . . ] The SD505-DTS also provides visual access to the SD505-ADHR in installations where the SD505-ADHR cannot physically be seen. SD505-DTS Wiring Wire the SD505-DTS to the SD505-ADHR as shown in Figure 8.
