St Louis county MO is 3 to 5 minutes of alert for tornado warnings and 1 minute of alert for tests. Thankfully I can hear them loud and clear even in my home in neighboring Jefferson county. Those 2910s sure do carry well. As far as I know they haven't been utilized for anything but tornado.warnings. The older system that was replaced recently used to occasionally be tested in fast wail back in the 80s up to the early 90s. I assume that was due to the cold war. The tbolts would default to attack while the 3016s would fast wail.

No paticular order..... It's Monday and it's lunch time if the weather is right, Tornados or "funny looking clouds that could become a Tornado as reported by someone with in the county ranks with a 2-way radio".... not a funnel or even a wall cloud ....true story :? , further increase in the amount of taxes paid to the county...some how the sirens are used as a political pawn in this game.

Have you even realized that Hamilton County and every surrounding county that had the policy of sounding the sirens for a Severe Thunderstorm Warning with a Tornado Watch eliminated it in 2011?
Nope. Did not know that.

The model 2 in my town was disconnected a long time ago, but I'm almost certain it was used for fire calls.

The model 2 in Gimli, Canada has a strange plan.

2-3 Minutes of Alert is used to signal fire calls (I think the website is outdated, since they've only sounded for 45 seconds whenever I heard them).

Continuous Alert (more than 45 seconds, I guess until power fails or something) means there is an emergency, and to take cover immediately.

Attack is used as an all clear signal.

Other: During the Icelandic Festival and on Canada Day, the siren is sounded for 45 seconds of alert, 5 minutes prior to the start of the fireworks show. I've yet to figure out why.

Apparently, the siren was only activated once for an emergency, back in the summer of 2003(?) for a downburst that caused moderate damage in Gimli and nearby Fraserwood.

Also, on a different note, Selkirk has a Model 5 on the water treatment plant, but I unfortunately do not know if it sounds or what it sounds for.

Had to dig up ours. City sent out info with utility bills last summer and posted to Facebook once so here is what we sound ours for.

"Very Important information on Drumright Tornado Siren Policy. Please read and share!

The policy of the Drumright Fire Department regarding sounding the Outdoor Warning Sirens (OWSs) is as follows:

Outdoor Warning Sirens are sounded if one of the following occurs:
1. A rotation signature is showing on radar 10 miles in any direction of Drumright city limits traveling with a storm heading in the direction of Drumright
2. Spotters in the field advise of tight rotation, funnel clouds or cloud to ground tornados are seen.
3. Reports from the news channels advise of a tornado on the ground, heading in the direction of Drumright or southwest/west of Cushing.
4. Straight Line Winds are detected by spotters or Radar at 75 MPH or higher

If the storm dissipates before it gets within 10 miles (by radar) from the city limits we do not sound the sirens, however keep our spotters in the field to keep a close eye on cloud conditions. A misconception with tornadoes is they move as fast as the wind speeds they produce. The average speed of a tornado is approximately 30-35 MPH. That gives the DFD a 15 minute alert time with a tornado within 10 miles.

The Drumright Fire Department won't sound sirens for the following:
1. Thunderstorms
2. High Winds (Unless it can be determined that speeds exceed 75 MPH)
3. Wall Clouds
4. Rotating Clouds without funnels
5. Flooding
6. All Clear signal"

Drumright, Oklahoma has 7 out of 7 sirens working as of July 15.

Tornado Warnings issued by the NWS, or local spotter reports indicating a tornado. Sirens in Watonwan County will sound in Attack for 3 or more minutes.

Nashville sounds the sirens whenever a tornado warning is issued for Davidson County.

The sirens sound in "attack" mode for 3 minutes when the warning is given. They are activated every 8 minutes throughout duration of the warning.

Regular test is first Saturday of month at noon; one minute of "attack."

Williamson County(next county S of us) has 3 systems; Brentwood, Franklin, and one for the county. All 3 use the "attack" signal for 3 minutes in event of tornado warning, but don't keep activating the sirens like Nashville does.

The above mentioned systems are tested at 1 PM on 1st Saturday of the month; also a minute of "attack."

Possibly sound for a Chroline leak?
