Duct widths from 15.3 to 30.5 cm can be accommodated. detector approved for an extended air speed range of 100 to 4000 feet per minute (0.5 m/s to 20.3 m/s) and an opera-tional … Therefore, duct smoke detectors are typically considered mechanical equipment devices instead of life safety devices. The detectors are standard-alone detectors or for connection to alarm monitors (alternative an amplifier module GP-AMP). By order, please specify if the detectors should be delivered with probe for mounting at ventilation pipe (drawing no. Exception: Installation of duct detectors can be on or within a commercial packaged rooftop heating and air-conditioning system, fire/smoke dampers and economizers . Overview. (3) Installation outside the duct with rigidly mounted sampling tubes protruding into the duct (4) Installation through the duct with projected light beam. and placing it approximately 3 inches from the detector head. E-PDD Duct Smoke Detector Installation Sheet Operation The duct smoke detector's primary purpose is to provide early warning of an impending fire and shut down the HVAC unit in order to prevent smoke from circulating throughout the building. The SM-501-N Ionization Duct Smoke Detector provides early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial, and Residential applications. The duct smoke detector is designed to operate in ducts with a width of between 300mm and 3000mm. The DNRW is a Watertight intelligent non-relay for use with ONYX Series panels. The DNRW is a Watertight intelligent non-relay for use with ONYX Series panels. CAUTION: Do not overtighten the screws. %PDF-1.5 Table 1 on page 3 to determine the inlet tube required for different duct widths. [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. Duct widths from 6 inches to 12 feet can be accommodated. NFPA 72 also states that a duct smoke detector is not allowed to replace an area smoke detector, mainly because if the air-handling unit (AHU) is not running, the detector would not detect smoke. Blow across the lit end of the clothesline toward the detector. RWF/J Series smoke duct detector should be greater than 0.01 inches of water and less than 1.2 inches of water. Air is sucked up the sampling tube, across the detector and exhausted back into the air duct. 1 Mount the pipe and the detector on the duct. 7.2 ALARM TESTS Before replacing the duct housing cover, check the detector interconnections. After performing this test sequence, reinstall the duct detector cover. After completing installation of the duct smoke detector, test the detector to ensure it is operating correctly prior to leaving the site. 4) When installing on the return side, install duct units prior to Siemens Industry, Inc. assumes no responsibility for improperly installed duct detectors. }������o�Q��oh����=�8Լ�'k���2������D����\�~I�hD跢��Z8oj�7��ƛđ�s=#��,6{���[��0b��Eʪ���a>��4O��a�%X������ۇ#�?����>�%�H ���e�$e�s�������n�������Z��?����eMQ��������TS#�_j����q@�9�Em}R�����~Zۼ|�a5�OB�O�τ�?5�ե�YNj�O�q��y����3�x$����a�C�O%!���� YF|S���j�R��h8���~�he��I�~�>k���/�����>h�~ԯ�X}D�P��1>-j��i��믪���׸��uj���맯k�n�DP?+�O�{�U��{?��~�`L��RU>*R���_���iׄ�����������S�]�F�b�f�����o��o�G�f��������V�?�"�Sq��Z���}/N���݃���lѯ?��sg��^�a��o����z%!�y��T0���?��~������Uhԗ��jnWZ�������_�y�h����Wf�CVi�0. Installation on the Duct. Removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away from components, ensuring years of trouble-free service. Unlike other duct detectors, flexible tubes can be used for installing the XAS duct detector in places where typical piping cannot be installed easily. Features & Benefits: Air velocity rating from 100 ft/min to 4,000 ft/min Adjusts to square and rectangular mounting configurations Patented tool-free, plug-in sampling tubes Continue reading endstream endobj startxref I'm explaining how fire alarm systems work for new technicians or other employees who deal with these systems. Wiring must conform to applicable local codes, ordinances and regulations covering these types of devices. NFPA 90A is specific to Air Conditioning and Heating Systems installation. They may be mounted in either the supply and/or return air section as determined by local code. The SDP-3 is a Duct Probe housing allowing a range of photoelectric smoke detection devices, either conventional or analogue addressable, to be mounted on the outside of an air duct for the purpose of monitoring the air within the duct. A duct smoke detector is a device or group of devices used to detect the presence of smoke in the airstream of ductwork sections of the HVAC air handling systems typically used in commercial buildings. Geopal offer a range of detectors for installation on duct and ventilation pipes, etc. TEJ electric also recommends you to test your duct smoke detectors once a month to assure they are properly working. Hochiki SDP-3 Duct Detector Mounting Box including 0.6m Pipe. 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. Check the DHX-501 as follows: A. M02-04-00 MAGNET TEST 1. To determine the correct installa-tion position for a duct smoke detector, the following factors must be considered. [5] DETECTOR INSTALLATION [5.1] VERIFY AIR FLOW DIRECTION AND VELOCITY Model D4120 detectors are designed to be used in air handling systems with air velocities of 100 to 4000 feet per minute.

SuperDuct detectors feature a unique design that speeds installation and simplifies maintenance. Blow across the lit end of the clothesline toward the detector. The perforated sampling tube which spans the duct is placed in the airflow upstream of the exhaust tube which causes a pressure differential in the duct detector. The operating principle of a duct detector is based on the Venturi effect. 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.
