Office Environment/ Personal alarms for each desk.....

[<32412@xxxxxxxxxx>]

I am looking to see if there is a readily available system that includes
alarm buttons at each desk (maybe 10 total) to trigger some alarm to notify
anyone else on staff to call security/911 if the front office deems that a
person has entered and is going to cause trouble.   Anyone heard of a system
like that or does it have to be pieced together?   Any help would be
appreciated.  Office staff will dial hospital security and 911, dont need
autodialer.  Just alarm and perhaps red flashing light?
