I make use of Trap Receiver running on a server (the one controlling the four large screens in the NOC) to receive a 'trap' from the alert manager and explode it to workstations in the NOC.
The workstations have the same program running that then fires a local action (in my case I have a WebMail Notifier | Dream Cheeky stuck on top of some monitors, and I blink it different colors using the code here: Dream Cheeky USB Drivers for Webmail Notifier and Stress Button - Home .)
I'm thinking of connecting a strobe light to a power controller to provide something more visible.
