– The D300A-HV is not intended for open area protection. Refer to the NFPA 90A and NFPA72E , for general and additional duct smoke detector operation and installation. DANGER! Follow the procedures in these instructions to avoid personal injury and/or damage to the equipment.
Verifying Air Flow and Direction Use the D300A-HV in ducts with air velocities between 300 ft to 4000 ft (91 m to 1219 m) per minute. Verify the air velocity by checking the duct installation specifications, or by using an Alnor Model 6000P (or equivalent) velocity meter.
Wiring must conform to applicable local codes, ordinances, and regulations covering this type of device. Wire the detectors according to the engineering drawing for that particular job requirement. For D300A-HV wiring details, refer to Figures 4.1 on page 7. Terminals are suitable for up to 14 AWG (1.8 mm) wire.
