For Models 609U21, 609U22, 609U23, and 609U24, when converted in the field for low voltage operation the electrical specifications of the similiar low <br />voltage card in Table 2 apply, For example, il you convert a Mode/609U2t for low voltage operation use the specifications of a 609U31, For a converted <br />609U22, use the specifications of 609U32, etc, <br />2, The Form A supervisory contact is closed with power applied, <br /> <br />3, Relay contact ratings shown are for a resistive load at 30 VDC or 120 VAC maximum, <br /> <br />Sampling Tubes <br /> <br />A pressure differential pulls air in through the inlet sampling tube <br />and into the sampling chamber, then sends it back out into the duct <br />through the outlet sampling tube, <br /> <br />Each duct detector housing is equipped with 5.25 inch inlet and <br />exhaust sampling tubes, The ends of these tubes are cut at a <br />450angle, The inlet tube faces upstream and the exhaust tube <br />faces downstream to ensure airflow through the housing, The <br />tubes provide the means of obtaining a sample of air from the duct. <br /> <br />Although this product Is approved for use without additional <br />extension sampling tubes, optional tubes may be required by the <br />authority having jurisdiction, OPTIONAL sampling tubes are <br />available in several lengths, <br />
