FM APPROVAL DESCRIPTION
FIRE DETECTION & RELEASING
• National Fire Alarm Code performance verified per NFPA 72-2013. Refer to Table A-1 for
device and circuit supervision characteristics.
• See section 2 "Field Devices Flame Detectors" for information regarding Det-Tronics approved
flame detectors and associated manuals. Additional two second response time applied for
system communication.
• I/O Modules EQ3700 DCIO series (Class B IDC/NAC) and EQ3730 EDIO series (Class A or B
IDC/NAC) Reference Table 3-10 for compatible solenoids used for automatic release of pre-
action and deluge sprinkler and extinguishing systems.
GAS DETECTION
FM Certificate No. FM17US0258X
Combustible Gas Performance verified for 0 to 100% LFL methane-in-air atmospheres per FM
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 veried.
• 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 veried 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 including UD10
DCU and CGS.
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.
NOTE
FM Approval allows the presence and operation of serial/Ethernet communications
software in the Controller (Modbus TCP/IP, Allen Bradley protocols, etc.); however, the
communications functions are not included in the Approval.
