The Siren Board

Don't forget your EM's job is to be an emergency manager, not to be the siren enthusiast in chief. I'd want to know how well he knows the emergency plans and where all the resources are, and how to get boats and rescue equipment, communications, and how to get help from other communities and FEMA.

The coverage in some areas may seem a little overdone, but those overlapping coverage radii go to hell when there's thunder rolling and wind howling and rain almost horizontal.

we have 3 sentry sirens..

Colwich has three sirens, a Model 5, a 2001 and a 2T22 all in line from north to south and 300 feet from each other.

Here is a 95% complete coverage map of Franklin County


This map is missing 1 siren in Grove City (newest) and a few in Dublin's seperate system. Franklin County's system consists of 11 Thunderbolts and Whelen 3016's/4004's. Dublin has Whelen 2750's and 2805/2905's

Here is our siren system. It covers almost the entire city limits of Muncie and the outer communities. Daleville and Yorktown have the biggest coverage issues.

What is one used for a noon blast, the other for the FD and the other for tornadoes? Are they maintained from Sedgwick county or is Colwich one of those cities who does their own.

Hamilton County, Ohio

They are all used for tornado warnings, no other purpose.

all we have is 6 whelen wps 2805's...and i must say i can hear 4 of them when they go off...the other 2 are too far from my house to hear lol

Where I live I'm not near any of the sirens in my county however, I live about a mile from a Whelen WPS-4004 from the next county. They are working, however, to get a countywide siren system where I live.

I've been doing alot of work in a neighborhood a few miles away from me in Dublin, OH. I've heard their system of Whelen 2750s and 2805s several times but never heard them up close until yesterday. I was able to catch a recording of one of the 2750s but I can't find the cord to transfer it to the computer. I'll post it once I get it uploaded which will most likely be later tonight.

Here's a map of the Dublin system. The red circle os the one I recorded and the blue circle is the one I took pictures of.

Here's a map of how far I was from the siren. The yellow box is where the house I recorded from was

This is the siren I recorded which is located on Bright Rd. between Campden Lakes Blvd. and Connie Dr.

Here's another one of Dublin's 2750s located in Scioto Park along Riverside Dr.

The siren head.

Underneath the head.

And here's the control/battery box. See that green cylinder with the cone on top? My best guess would be that it's some kind of insect trap because underneath the cone is a light bulb and beneath that is some kind of conve shaped screening. All of their sirens that I've seen has these and if I guessed correctly on what it is I assume it's to help prevent insect nests being built in the controls and speaker arrays.

The visual difference between a 2750 and a 2805 is that the supports between each "plate" on a 2750 are silver and on a 2805 are black. Also, 2750s have no visible screening between speaker driver housings and the 2805s do. Sound wise a 2750 sounds pretty much the same as a 2016 or a 3016, high pitched, aprupt windup and slow windown. 2805s have a much deeper tone.
