Pictured below is a smoke detector installed as per (3) above; where there detector is installed outside the duct and a rigidly mounted sampling tube protrudes into the duct. The SuperDuct detector is a slim feature-rich alternative to bulky duct smoke detectors. Designed for easy instal-lation and superb reliability, SuperDuct represents the perfect balance of practical design and advanced tech-nology. Be sure to check engineering … Siemens Industry, Inc. assumes no responsibility for improperly installed duct detectors. INSTALLATION AND MAINTENANCE INSTRUCTIONS. See … Duct Smoke Detector Installation; Everyone needs a duct smoke detector system around if they don’t want to put their lives (and others’) at risk. Model Description . First, though, you can at least try to reset the duct detectors yourself by shutting off the power to the RTUs for about 5 seconds and then turning the RTUs back on. They must be the cor- rect length for the width of the duct where they will be installed. Air flowing through the duct is forced into the air intake (inlet) tube via the air intake holes, (facing the airflow) and passes over the detector head. For HVAC systems with airflows exceeding 2,000 cfm, duct smoke detectors are required. Observe alarm LED operation. A duct smoke detector comprises a plastic housing with two air tubes (inlet … SL-2000 Series smoke duct detector should be greater than 0.01 inches of water and less than 1.2 inches of water. Installation on the Duct. Be sure to check engineering specifications to … With all wiring in place, install the detector head. [5.4] SECURE THE DUCT DETECTOR TO THE DUCT Use two (rectangular configuration) or three (square configuration) of the pro - vided sheet metal screws to screw the duct detector to the duct. They may be mounted in either the supply and/or return air section as determined by local code. endstream endobj startxref The operating principle of a duct detector is based on the Venturi effect. The duct detector housing provides a 20mm conduit knockout and ample space to facilitate easy wiring and mounting of relay module. The detector is designed for use in air handling systems with air velocities between 300 ft/min and 4000 ft/ min (1.5 m/s to 20.3 m/s). Removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away from components, ensuring years of trouble-free service. A duct smoke detector should shut off a typical blower and fresh air and turn on the exhaust Duct detectors aren’t a replacement for room sensors If the duct system is designed to carry more than 2000 CFM (5 tons nominal) of air you need one in the return if IMC is … [4]DETECTOR INSTALLATION [4.1]VERIfy DUCT AIR fLOw DIRECTION AND VELOCITy Model D355PL detectors are designed to be used in air handling systems hav-ing air velocities of 100 to 4000 feet per minute. The air will be drawn out via the exhaust tube back into the HVAC duct. They may be mounted in either the supply and/or return air section as determined by local code. 2 0 obj [4]DETECTOR INSTALLATION [4.1]VERIFY DUCT AIR FLOW DIRECTION AND VELOCITY Model DNRE detectors are designed to be used in air handling systems hav-ing air velocities of 1.5 to 20.3 m/sec per minute. INSTALLATION INSTRUCTIONS FOR THE DUCT SMOKE DETECTOR Before installing the duct detector, you must verify the duct air flow and velocity. InnovairFlex™ duct smoke detectors simplify the duct detection installation process saving you time and money while still providing the flexibility you need in the field. installation of the damper and smoke detector. FX-PDD Duct Smoke Detector Installation Sheet - UTCFS Global ... READ GESecurity FX - PDD Duct Smoke Detector Installation Sheet EN FREN: Installation Instructions FX - PDD Remove the duct detector cover. APPLICATION National and local safety standards and codes recognize the ability of air duct systems to transfer smoke, toxic gases and flame from area to area. Why taking care after the installation of your duct smoke detector is important:-Malfunction can take place on your installed duct smoke sensor in case you accidentally paint it. Wire the detectors according to the engineering drawings for the particular job requirements. 49 0 obj <>stream In a duct application, two flexible tubes are installed. After performing this test sequence, reinstall the duct detector cover. The DNRW is a Watertight intelligent non-relay for use with ONYX Series panels. Duct widths from 15.3 to 30.5 cm can be accommodated. SM-501 Series smoke duct detector should be greater than 0.01 inches of water and less than 1.2 inches of water. We offer the best service when it comes to duct smoke detectors: state-of-the-art devices that cover all the functions you need to keep your environment free of any hazard. Check the DHX-501 as follows: A. M02-04-00 MAGNET TEST 1. The duct smoke detector can be customised to meet local codes and speci˜ cations without additional wiring. The purpose of the NFPA 90A is to prevent the spread … the AD2 Series smoke duct detector should be greater than 0.01 inches of water and less than 1.2 inches of water. [6] SAMPLING TUBE INSTALLATION ing out of the duct, select a shorter tube using [6.1] SAMPLING TUBE SELECTION Two tubes extend into the HVAC duct. The following table lists the replacement parts for the duct smoke detector. Key Features. h�bbd``b`� $�#?�`��^@B8H>�+���:H"$�HH��E�ԁd�@\�(&F�� F2����� �~) (3) Installation outside the duct with rigidly mounted sampling tubes protruding into the duct (4) Installation through the duct with projected light beam. Duct Smoke Detector Installation Guide General Duct smoke detectors provide early detection of smoke in the air moving through heating and ventilation (HVAC)ducts in commercial and industrial premises. Duct widths from 6 inches to 12 feet can be accommodated. 4) When installing on the return side, install duct units prior Blow across the lit end of the clothesline toward the detector. 20 0 obj <> endobj 2 Use a cable gland (PG13.5 or M20). <>stream Air is sucked up the sampling tube, across the detector and exhausted back into the air duct. If the airflow is bouncing all over the ductwork, it is less likely to make it into the sample tube as required for proper smoke detection. This guideline contains general information on duct smoke detector installation, but does not preclude the NFPA documents listed. The Innovair DH100ACDCLPX model is a photoelectric .

The Notifier DNR(A) intelligent non-relay photoelectric duct smoke detector and DNRW watertight non-relay photoelectric duct smoke detector feature a pivoting housing that fits both square and rectan- gular footprints capable of mounting to a round or rectangular duct. Table 1 on page 3 to determine the inlet tube required for different duct widths. 0 3) Identify a code compliant location (supply or return side, or both) for the installation of the duct unit that will permit easy access for viewing and serviceability. 4) When installing on the return side, install duct units prior Updated every hour with fresh content, Centsless Books provides over 30 genres of free Kindle books to choose from, and the website couldn’t be easier to use. SuperDuct detectors feature a unique design that speeds installation and simplifies maintenance. 3) Identify a code compliant location (supply or return side) for the installation of the duct unit that will permit easy access for viewing and serviceability.
