What kind of siren is this?

The siren sounds a bit like a Screamer, though it also sounds somewhat like a Hormann electronic siren, from the American company.

It sounds mechanical to me; but the frequency sounds too low for a Screamer.

An ACA Howler mebbe? Or an RM-127?

Sentry?

[jkvernon]

It sounds like either an ACA Screamer or a Sentry. It may be underpowered or something.

i think its a sentry since the wide up is quick

It is neither a Screamer nor an E-57, which would both sound a whole step higher since they almost always have nine ports. Given the husky sound, quick rise, and apparent lack of rotation, my guess would be either a Sentry siren, such as a 20V1T, with a large motor, an 8-port Federal Model 7, or a smaller ACA siren like the T-121. Given that battery run sirens tend to run a little faster, I'd go for the Sentry or the Federal. A Howler, which I understand is the same as a single-toned Banshee, could also be possible.

Most likely a sentry, It sounds like it has an induction type motor.

[Hacksaw]

It doesn't sound like a Model 5/7 single tone to me.

I'm coming on board with those who think it's a Sentry 20V. Maybe a Sentry 10V?
