Suggestions Help for server client communcation

Question

I have 12 display monitors installed in different floors in a building. These monitors display announcements that will be update once in a day. i'm retrieving these announcements from db and storing in an array and displaying it all day long.

In addition to this, I have a requirment to display emergency alert messages on the monitors. My Server is a windows 2000 server. i'm using asp for creating the JSON object.

for the emergency alert im thinking of doing this

Create a page in asp that lets user to enter emergency msg and save to db. create a page in asp that will check if there an emergency msg in db and show it in a asp page in json. Create a timer that pings this json page every 1 second. if it's available then show it.

Is there any other sophisticated method available to poll the server or to send messages from server to client?

Since its only for 12 monitors I'd go with the solution you have chosen. Using web-sockets with something like node.js would be fun but i think its a bit overkill for this.
