Current from the Cathode side of the flashtube (FTC1, FTC2, and
FTC3) are sent through the current sensing transformers T1, T2, T3,
T4, T5, and T6 on PCB #1. T1, T2, T3, T4, T5, and T6 will send a
pulse to the gate of the SCR's Q6, Q8, Q10, Q13, Q14, and Q17, and
turns it on. Capacitors C12, C13, C14, C15, C16, and C17, via Q6,
Q8, Q10, Q13, Q13, Q14, and Q17, will send voltage to LED1 (D20),
LED3 (D21), and LED5 (D22). After each confirmed flash, LED1, and
LED3 will blink. Absence of a blinking LED signifies that strobe
beacon has ceased to flash.
3.7.8 Strobe Fail Test
Switch S1, when turned on, cuts off timing signal to the trigger circuit
and extinguishes LED8 (D12). At this time the strobe alarm should be
received at J3. The normal position of S1 is off (switch downward).
