On the Subject of Who’s on Morse

This contraption is like something out of a military bunker, which might be interesting if it wasn't connected to a bomb. I’ll keep this brief, as Morse only complicates matters.

1. Determine the flashing word in Morse code by the light at the top of the module. The signal will loop, with a long gap between repetitions. Use this word in section A to determine which of the four LEDs to read.
2. Using the letter this LED is flashing, use section B to determine which LED to push.
3. Repeat until the module has been disarmed.

Section A

Based on the flashing word, read the flashing letter of a particular LED and proceed to section B:

SHELL	HALLS	SLICK	TRICK	BOXES	LEAKS
STROBE	BISTRO	FLICK	BOMBS	BREAK	BRICK
STEAK	STING	VECTOR	BEATS	CURSE	NICE
VERB	NEARLY	CREEK	TRIBE	CYBER	CINEMA
KOALA	WATER	WHISK	MATTER	KEYS	STUCK

Section B

Using the letter from section A, push the first LED that appears in its corresponding list:
