AIR-IntelligenceTM ASD-320 Aspirating Smoke Detection
This equipment is only to be used in accordance with this specification. Failure to operate the equipment as specified may cause damage to the unit, injury or property damage.
FEATURES AIR-IntelligenceTM ASD-320 Aspirating Smoke Detection
The following is a list of major features of the ASD-320:
• Patented “artificial intelligence” known as ClassiFire
• Laser Dust Discrimination (LDDTM)
• 330 feet (100 m) of pipe length
• Self-adjusting between the range of 0.05% and 2.0% obscuration
• Network compatible with other AIR-Intelligence detectors and Command Module
APPLICATION
The ASD-320 is intended to provide small area incipient fire detection. This means that it is suitable for the substantial range of applications typified by small compartmentalized rooms, warehouse racking, or pieces of electronic or electromechanical equipment where it is desirable to achieve individual incipient fire reporting. In compartmentalized rooms, each compartment would normally use an individual AIR-Intelligence detector.
The ASD-320 is not intended to protect large areas, or to sample areas where there may be any difference in airflow rates or pressure differentials. If detection in environments conforming to these descriptions is required, other AIR-Intelligence products should be used.
