OK I found the model number It is a 12-255, Here is a link to a pic 
and more info.
http://support.radioshack.com/support_tutorials/weather/12-255.htm

At first glance it says it will remain on for 5 min after an alert 
but if you look closer it also says

"...VOICE — the Weatheradio sounds an alert for
about 8 seconds, then automatically turns on the
weather (voice) broadcast for 5 minutes or until the
NWS transmits an ending sequence, whichever
comes first...."


Another interesting about this radio is that the alert tone goes 
through a different audio path than the main audio so you can choose 
to either send the radio's siren or not.

I choose not to and use this time to send a Weather Alert message. 
In the past I have also added DTMF tones so people with ham radios 
capable of decoding dtmf to unmute could monitor the repeater and be 
alerted to severe wx.

Anyway works really well for me. I don't know if they are still 
available though
