Federal Q question

Wed May 18, 2016 10:27 pm

I may have posted this before, I am getting old and can't remember.... we are all familiar with the Federal Q on fire apparatus and know how they sound. I have been trying to figure this out for awhile, there are some versions of the Q that has a slower wind up and don't peak as high... looking at them they look the same as a normal Federal Q but there is something different with them. Anyone have a clue as to what was different? I always thought this was the A series of Federal Q but I can't seem to find a reference to them. If you watch the video below there are 3 pieces of apparatus making this corner, Engine 2-1 from Waynesboro is first.. it has a normal Q, Engine 4-2 from Blue Ridge Summit is next and it also has a normal Q, the third engine is from the Leitersburg Fire Department in Washington County, MD and it has the Q I am talking about. Any thoughts my fellow countrymen?

Could it just be the electrical system on the vehicle? or maybe different number of ports?

It could be a Q2A vs Q2B thing.

Federal Q's have always had the same number of ports (15, IIRC?). I'm not a total expert on apparatus sirens, but I would say either the strain on the vehicles electrical system or the wear on the siren itself.

They've used several different types of starters motors over the years which has an effect, but most of the time it's just the electrical system (smaller wire, corroded connections, alternator and battery too small, etc.).

Jake, the only difference between Q2A and Q2B is the B has a brake

Sounds like it might have foot switch or a Captains switch (usually located on the dash in front of the Captain) Local apparatus has/had the air horns activated by a switch on the dash in front of the Captain. I think that the retired apparatus from here that ran "Q"s ran foot switches(late 40's - mid-late 50's American LaFrance mostly) Push buttons on the dash looked like an upside down thimble mounted with in a simple face plate that was pushed like a door bell...foot switch's looked like a dimmer switch (go ask grampa) either operated by the driver or Captain. As long as the switch is pushed the "Q" is running, let off of the switch for a wind down. I.M.H.O the switched "Q" as I described sounds more like what I heard 40 + years ago(because that's how it was done back then) verses a "Q" that can be activated off of the steering wheel or master siren control like what it sounds like with the first 2 responding units .
