MSC8 number 4 has several outputs controlled by one operation. The smoke generator is operated by a sequence; it is on for approx 1 minute every 5 minutes. When the smoke generator output is active (i.e. for that 1 minute when the building is on fire) outputs 2, 3, 5 & 6 are activated. These then have their own sequences: to flash the fire engine lights, and to flicker LEDs to look like the fire itself.
MSC8 number 4 Output 7 has 2 sequences: a sequence that flashed the lights like a fire engine; and that whole output is turned on or off by output 8, which is on infrequently. This will give the appearance that a fire engine inside the fire station has its lights tested periodically.
