Universal Stopper

The 13420FR Universal Stopper indoor/outdoor cover from Safety Technology International Inc. helps prevent false fire alarms while it guards against accidental or intentional physical damage. Attracting attention before the pull station is activated, the interior horn is triggered when the cover is lifted. Constructed of clear polycarbonate, the stopper contains a waterproof cover with a 105-decibel horn, enclosed backbox and sealed mounting plate. Sized to fit most pull stations, it has a high strength continuous hinge, according to the company. The unit can also come with or without horns.
