FM Approval and performance Report
THE FOLLOWING ITEMS, FUNCTIONS AND OPTIONS DESCRIBE THE FM APPROVAL:
• Explosion-proof for Class I, Div. 1, Groups B, C and D (T5) Hazardous (Classified) Locations per FM 3615.
• Dust-ignition proof for Class II/III, Div. 1, Groups E, F and G (T5) Hazardous (Classified) Locations per FM 3615.
• Nonincendive for Class I, Div. 2, Groups A, B, C and D (T3) Hazardous (Classified) Locations per FM 3611.
• 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 (oi) 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 oi performs the same calibrated test as the Automatic oi, 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.
