Review: STI-13020FR Fire Alarm Pull Station Covers - This cover by Safety Technology Int. does what it is suppose to do. Sounds an audible when cover is lifted good chance of preventing a false call to fire department. Just have to wait many months for them. I ordered 3 each STI-13020FR stoppers on Sept. 16 and 1 more on Sept.18th and it is now Oct 22 and they (desertcart) might be shipping another one soon. When I placed the orders 2 were supposedly in stock. But still took weeks for them to ship only 1 of them out.
Review: Love the pin that stops the horn while you are installing. Others have a switch you can accidentally hit and be tortured by the sound
