The FDMET400 detectors allow to signal the presence of natural gas concentrations lower than
the lower explosive limit (L.E.L.), i.e. 10%, long before an explosive mixture is composed. The
detector is equipped with a relay alarm output with contact exchange (NO and NC), a malfunction
output with optically isolated NC contact and two terminals to connect a power absorption line for
conventional control units.
Supply voltage: 11 ÷ 29 VDC
Absorption at rest: 60mA at 12 VDC - 30mA at 24 VDC
Alarm absorption: 70mA at 12 VDC - 40mA at 24 VDC
Line alarm absorption: 50mA at 24 VDC
Delay for alarm: 20 seconds
Delay for alarm reset: 30 seconds
Alarm threshold for detection: 10% LEL – 0.50% in volume
Alarm relay output: (NO-NC) 1A, 30 VDC resistive load
Malfunction output: optically isolated NC contact 20mA, 30 VDC
