WARNING

!
THE AEROSOL FROM THIS INSTRUMENT MAY BE HARMFUL TO THE HEALTH OF THE OPERATOR IF
PRECAUTIONS ARE NOT TAKEN.
The Model 501-B Aerosol Generator/Smoke detector Analyzer generates an aerosol consisting of a refined NF-Grade white
mineral oil in air. Aerosol concentration at the discharge point of the hose is adjustable from 0 to 45 mg/m 3 (0 to 6 mg/min).
Room air would dilute the discharge quickly. The aerosol smoke is odorless and not visible. Proper precautions to avoid
over exposure such as good ventilation and limited discharge time are recommended. Do not hold end of hose close to face
during aerosol discharge.
The maximum allowable limit under OSHA (Occupational Safety and Health Administration) regulation in an eight-hour
weighted average for oil-based aerosol is 5 mg/m 3 . The RUDOL
TM
White Mineral Oil is approved by the FDA (Food and
Drug Administration) for use on skin and incidental food contact.
To reach the OSHA allowable limit, for example, you need to discharge at the maximum concentration rate (6 mg/min)
into a non-ventilated 14x12x10 feet room for a period of about 50 minutes. However, in typical testing, very little aerosol
is introduced into the room. The normal time per test is only about 30 seconds at 1/4 of the maximum concentration, far
below the OSHA safety limit. However, precaution is necessary to avoid situations where exposure can reach above the
OSHA limit.
THIS INSTRUMENT SHOULD NOT BE USED IN OR NEAR CONCENTRATED OXYGEN ENVIRONMENTS SUCH AS
OXYGEN TENTS OR OPERATING ROOMS IN A HOSPITAL.
THIS EQUIPMENT OPERATES AT VOLTAGE LEVELS THAT CAN BE HAZARDOUS TO OPERATING
PERSONNEL.
The Model 501-B Aerosol Generator-Analyzer for Smoke Detectors operates on a rechargeable 12V Ni-Metal Hydride
battery. This voltage appears at the serial number label and various other points on the chassis. The power of the
instrument should be completely turned off before opening the front panel for filter change or repair. Only qualified
personnel, who are familiar with the location of the voltage and the hazards involved, may open the cabinet with power
circuit energized. When connecting a new battery, make sure to observe correct polarity. Connect the red positive (+)
line to the red positive (+) battery terminal and connect the black negative (-) line to the black negative (-) battery
terminal.
