the local Walmart is interesting. It has ceiling-mount Spectralerts horn/strobes and remote strobes throughout the store. Wall-mount remote strobes in the bathrooms. However there are a couple of Wheelock MTs hanging on the wall in a couple areas.
They have clear strobes. I would think the clear strobes were ADA compliant whereas the older translucent strobes like on the Wheelock 7002t were not. Maybe I am incorrect here. They have clear vertical strobes.
Yeah I do believe they are disconnected. They were the older alarms which the Spectralerts replaced, I believe.
