The 2001SRN, 2001DC, and 2001AC used a belt driven rotator like the Thunderbolt which required a larger rectangular rotator box. The 2001SRNB and the 2001-130 are gear driven and don't require the larger box so they're more square. Also, the 2001SRN used a smaller box on the back and was slightly higher pitched than the 2001DC or AC.
same here except Kansas City has been 2001 only since '91 after the thunderbolt at downtown airport was hit by a plane during the '91 air show. Within a month a 2001 was already screaming away like fingernails on a blackboard. lol
@TheFiremansavage I appreciate the explanation. Actually the difference between the two is the rotator mechanism and housing. The SRN has the Thunderbolt-style rectangular rotator housing for it's belt driven rotator while the SRNB rotator housing is more like an even sided cube housing a direct gear driven rotator.

Heyde1979 3 years ago 5
maybe on the map...but it may not reach everyone's ear.
crispyb317 3 years ago
do you have a solution that problem
Heyde1979 3 years ago
lower toned siren and one that puts out more DBs, like a t-135 ir sentry sirens. the best ones are the old CD sirens, such as the thunderbolt
crispyb317 3 years ago
I agree thanks for the input
Heyde1979 3 years ago

That's a shame that this is the only siren Halstead has. Are they really too small for more sirens or is it something else?
BellyLover06 4 years ago
it would be nice if we had one further north but what can I say. you can hear the siren all over town but if your inside it's kinda hard to.

Where exactly is this siren located on 6th St.?
jayhawk29 4 years ago 2
it is 6th and santa fe. its on school property between the middle school and high school

That siren is a 2001 SRNB.
CoolBalla15 4 years ago
It actually appears to be a 2001SRN, not a 2001SRNB. It looks like it has the normal TBolt style rotator housing.

What's the difference between the 2?
CoolBalla15 4 years ago
@thecompanycar SRN and SRNB are the same thing SRN stands for siren
