Model 3100 Series Flame Detector (11/04)
1. If the relay closes (0 ohms on the meter) and
the LEDs come “on” the detector is operating
normally. Check external alarm initiating cir-
cuit wiring.
2. If the relay closes and the LEDs remain off,
or the relay remains open and the LEDs come
on, the detector needs factory service.
3. If the relay remains open and the LEDs re-
main off, contact the factory for further diag-
nostic information.
