Review on Powerful Wheelock WHTB-593 Alarm Bell by Jim Bethea

This bell is nice and loud for working next to two large CNC machines and Kaeser compressors. I have the ringer volume set to maximum as it is installed on panels throughout the store. The included screws and RJ-11 connector made it easy to mount to a Superstrut mount I made for hanging on the wall. They require an RJ-11 voice cable and should be hung vertically for best performance. I have this paired with a Grandstream HT-802 ATA in a ring group for my Polycom desk phone which I cannot hear when it rings.
