The General Monitors FL3111 (FL3111-2-5-1-3-1) is an ultraviolet flame detector for the onboard fire alarm installation, where it watches a protected area for the UV radiation given off by a flame and signals the alarm panel. It runs on 24 V DC, draws 3.6 W and carries relay outputs rated 30 V RMS / 42.2 V peak at 1 A. Temperature class markings cover T4 up to a 90°C ambient and T5 up to 75°C, from a lower limit of -40°C. The detector is offered in new open box condition.
