Nonincendive for Class • II, Div. 2, Groups F and G (T3) Hazardous (Classified) Locations per FM 3611.
Enclosure rating NEMA Type 4X per NEMA 250.•
Ambient Temperature Limits: –40°F to +167°F (–40°C to +75°C).•
Automatic Fire Alarm Signaling Performance verified per FM 3260 (2000).•
The following performance criteria were verified:
OPTICAL INTEGRITY TEST:
The detector generated an optical fault in the presence of contamination on any single or combination of lens surfaces
resulting in a loss of approximately 50% of its detection range, verifying that the detector performs a calibrated
Automatic Optical Integrity (o
i
) test for each sensor. Upon removal of the contamination, the detector fault was cleared
and the detector was verified to detect a fire.
The Manual / Magnetic o
i
performs the same calibrated test as the Automatic o
i
, and additionally actuates the alarm
relay to verify output operation. If there is a 50% loss of its detection range, an alarm signal is not generated.
