hazardous locations
• Refer to Figures A-1 and A-2 for System Classification details.
• EQxxxxEM versions rated nonincendive for Class I, Div. 2, Groups A, B, C, D (T4A).
fire detection & releasing
• National Fire Alarm Code performance verified per ANSI/NFPA 72-2010. Refer to Table A-1 for supervision
characteristics.
• Refer to the Model X3301, X5200, X2200 and X9800 manuals (see Table 2-4) for further FM flame performance
details. Additional 2 second response time applied for system communication.
• Models EQ3700 Series and EQ22xxARM Series are Approved as agent releasing circuits and are Approved for use
with the following automatic deluge and pre-action solenoids:
gas detection
• Combustible Gas Performance verified for 0 to 100% LFL methane-in-air atmospheres per FM 6310/6320.
Accuracy: ±3% LFL from 0 to 50% LFL, ±5% LFL from 51% to 100% LFL. For the Model PIRECL, refer to the
PIRECL manual (form number 95-8526) for further FM gas performance details.
NOTE: Detector Electronics combustible gas detection K factors are not FM verified.
• H2S Toxic Gas Performance verified 0 to 20, 50 or 100 ppm per FM requirements. Accuracy: ±2 ppm from 0 to 20
ppm, ±10% of concentration from 21 to 100 ppm. Models C7064E4012 and C7064E5012 Hydrogen Sulfide (H2S)
Sensors Explosion-proof for Class I, Div. 1, Groups C and D Hazardous (Classified) Locations per FM 3615. Model
C7064E5014 Hydrogen Sulfide (H2S) Sensors Explosion-proof for Class I, Div. 1, Groups B, C and D Hazardous
(Classified) Locations per FM 3615. Operating temperature limits are –40°C to +40°C.
NOTE: Sensor cross sensitivity has not been verified by FM.
• Calibration of the above listed sensors has been FM verified using the respective EQ22xxDCU, EQ22xxDCUEX,
and PIRECL with the Det-Tronics 225130-001 (50% LFL methane) and/or 227115-001 H2S Calibration Kits.
• The EQ22xxDCU Series can be used with any FM Approved 4-20 ma device.
NOTE
FM Approval of the 4-20 ma input does not include or imply approval of the gas detection apparatus such as
sensors, transmitters, or devices connected to the system. In order to maintain FM Approval of the system, all
4-20 ma gas detection instruments connected to the input must also be FM Approved.
