Det-Tronics 007941-001 — EQ2220GFM Ground Fault Monitor for the Eagle Quantum Premier fire and gas alarm control system.
An EQP system runs from a floating 24 Vdc source, so a single ground fault produces no visible symptom while leaving the system one fault from misoperation. This module watches for that.
- Detects positive and negative ground faults on the 24 Vdc supply and secondary I/O circuits
- Separate + GND FLT and - GND FLT yellow indicators plus a green power LED
- LED responds at once; the relay contact needs the fault to persist 10 seconds
- Form C contact rated 1 ampere resistive at 30 Vdc maximum
- 24 Vdc nominal, 18 to 30 Vdc, 1.0 watt maximum, 0.018 A standby and alarm
- -40 °F to 185 °F (-40 °C to 85 °C), 5 to 95 percent RH non-condensing
- DIN rail mounting, shipping weight 0.5 lb (0.2 kg)
It is an accessory, not a controller: it mounts in the EQP Controller enclosure, and its Class I Division 2 Groups A to D T4 rating applies only inside a suitable certified type rated enclosure. The EQ21xxPSM (006979-001) is the similar module supervising ac voltage and battery charging current.
