Many questions

[texaschad25]

1. Will the Cones on a STH10 fit on a 2T22??

2. If offered, would you rather have an SD10, an allertor, or a penetrator?

3 What is the weight of the above sirens.



Thanks,

Hmm Allertor it's juts very weird.

Quite possibly. Only saying this as I would assume that Federal Signal would do this to cut down on manufacturing costs...

If offered, would you rather have an SD10, an allertor, or a penetrator?

SD-10. I would say it's less likely to fail because there's less complexity in the design, but it's completely up to you if the siren isn't for an operational role.

What is the weight of the above sirens.

Only guessing, but the SD-10 looks to weigh about 100-150kg, Allertor and Penetrator might push 200kg.
Purely an 'observational weighing'. I have no idea how much they would actually weigh.

No, STH10 and 2T22 cones are not interchangeable. The 2T22 manual on this site says the weight, I forget what it is off the top of my head.

2.) I would take the SD-10 because it is one of my favorite sirens, but if i was installing the siren in a town i would go with the penetrator because i believe it's louder then the SD-10 and correct me if I'm wrong but don't all penetrators come with battery back up?

1. No they won't. STH10 projectors are round on the end and 2T22/STL10 projectors have rectangular ends.

2. Allertor.

3. 2T22 is around 500-600 lbs. I believe (depends on phase and mount). STH10 is 363-403 lbs. (depends on phase and mount). SD10 weighs 510-550 lbs. (depends on phase and mount). Allertor weighs 425-500 lbs. I believe (depends on phase). Penetrator weighs about 450-500 lbs I think (depends on phase). Penetrator 50 weighs about 1500 lbs.

I don't believe Penetrators came with battery backup. That was the RM series...basically just like a Penetrator, but I believe the housings were a bit different in the front (more like the T-128's flower?). RM-127 to be exact I believe.

All I can answer is #2. I'd take the SD-10 because it's an omnidirectional siren. I prefer the European method of using many, smaller omnidirectional sirens versus the current American method of using fewer, larger rotating sirens. This way, if one fails, there are plenty of others to provide adequate coverage. Also, the SD-10 is a simple design, dual-toned (sounds like an "air raid siren," not a fire truck), and easier to repair. Rotating sirens, on the other hand, have a fading effect that blurs the difference between alert and attack signals.

Sounds like there is less to go wrong with an SD10 since it does not rotate. I was watching some vids on youtube and it looked like some of those Allertors would stop rotating or not rotate at all. Is this a problem with the rotating sirens?

Yeah, with rotating sirens there always seems to be rotator problems. Just a couple of weeks ago i was filing a 2001 doing a monthly test and towrd the end the rotator stopped working. Not sure if they got that fixed yet...

I'd like an SD-10 because it takes up the least room and can make a nice picnic table!
It generates a perfect 4th which produces a salty raspy resultant.

The 2t22 seems closer to 350 to 400 lbs. (Federal Signal's published weight is shipping weight including the pallet and supporting braces, etc.)
The 22 cones total 110lbs. I was able to remove the upper and lower intake tubes and they were not too heavy.
The three-phase motor and rotor/stators []=[] was the heaviest part.

I'd really like a 500T to paint like a sunflower!
If I had an Allertor, I'd place it at the driveway with it's snorkel as a mail box. (Uh-oh. There go my karma points.)
