I have an issue with staff turning down the volume on their workstations thus eliminating the alert sounds generated by alarms such as propped doors, troubles, etc. Obviously we have policies intended to prevent this but it still happens. I have asked the various manufactures for solutions without success (other than to put a sounder at the desk controlled by an output relay). What I am looking for I guess is a "breakthrough alarm feature that can be evoked on a point-by-point basis but I am open to suggestions.
Any ideas out there?
