Plug-in Amplifier Modules permit the selection of ultra-\n violet, repetitive self-check ultra-violet, AUTOCHECK infrared, or rectification methods of flame\n detection. The control system includes a safe start check, effective on each start. If flame signal\n (real or simulated) is detected, the unit cannot be started. For increased safety and reliability, Fireye\n 72D1R3 AUTOCHECK infrared amplifier (using the pulsing flame signal) and 72DUVS ultraviolet\n amplifier (using a scanner shutter) check the function of the flame detecting system for component\n failure during each burner firing cycle. Meter test jacks on each amplifier module provide flame signal\n readout with a DC voltmeter. Flame failure response time is four seconds (max.). When amplifier modules\n with T suffix are used, the flame failure response time is reduced to one second (max.).\n The control provides three SPDT and one SPNO load switches for external loads and starting cir-\n cuits.
