Weather Stopper® covers protect manual pull stations from impacts and help prevent false fire alarms without restricting legitimate alarms. The cover can easily be lifted and is connected to the frame by a metal cable. It was designed for indoors use as outdoor use. Such an accessory requires a double action to trigger a fire alarm compared to a simple pull station which requires one sole move.

All labelling on the cover are in French, however the instructions provided in the package are only available in English (PDF version available for download).

Polycarbonate properties:
Polycarbonate is a clear low flammability material highly resistant to impacts which features impressive mechanical and thermal properties, hence its use in so many fields. It is commonly used to manufacture safety eyewear, protective faceshield, law enforcement shield, optical lenses, thermal imaging and so many other vandal-proof items. The polycarbonate used for the fabrication of Weather Stopper® covers is UV-stabilized against degradation caused by the sun.

Maintenance and life service:
Some basic practices should be adopted to maintain manual pull station covers. It is thus recommended to wash the cover with lukewarm water and a gentle soap. The manufacturer strongly advises not to use steel pads since they scratch any surface they touch which will temper with the legibility of the label. It also is not recommended to use harsh soaps on the cover since polycarbonate doesn’t mix well at all with a wide array of acids and other chemical compounds. Indeed, these products will make your cover kind of melt. If the cover surface isn’t soft to the touch and bubbles appear, the cover has been corrupted and must be replaced.

As for its life service, the manufacturer asserts that his Weather Stopper® covers are durable; some have been in service for almost 20 years.
