You could look at using nut to manage your UPSes. There is a command for 
setting parameters, but I don't know if will turn off the (audible?) alarm 
for your particular UPS. upsrw or upscmd would be what you want, but you 
need to be using nut to monitor the UPS and you need to do some config file 
setup.
