Thunderbolt 1003

Fri Jan 20, 2017 2:35 pm

Did the original Thunderbolt 1003 have 3 cabinets or just two? Correct me if i'm wrong 1 for Siratrol, 1 for the RCM, and one for the Flasher?

You are correct. One cabinet is the RCM1, one cabinet has a Siratrol and AF timer, and the third is the RCM3 with the flasher unit in it.

That strikes me as odd because the Thunderbolt 1003's we have in Scottsbluff Nebraska have 2 cabinets and then a grey cabinet as shown in the picture. I'm guessing our Tbolts aren't equipped with a siratrol? They were installed in the mid 70's and were used for fire calls along with weather and civil defense warnings.

I'm guessing one box is for blower, rotator, and blower, while the other is for solenoids. As for the Beige box, imma say that's probably for radio.

Blower, chopper and rotator (the RCM-1), the solenoids (RCM...-3?) and the grey box was most likely communications to the siren. Thunderbolts in the 70s were (last I checked) usually set off by phone line but sometimes by radio? (Mine was set off by phone line when it was serving waldport... its a 60s bolt but it spent the first few years serving Spokane.)
Own and love a Thunderbolt 1000 and a Model 5.

There is an antenna on that gray box guys...evidently some other type of radio control was used...
