The Weather Stopper II offers protection against harsh environments and conditions both outside and inside, as well as preventing tampering, vandalism and damage from accidental or malicious operation. The cover does not hinder legitimate operation of a manual call point in the event of an emergency and a 50mm spacer is available.

Custom labelling is available on the UL listed product and gaskets seal the unit preventing dust, grime and water from getting to the device, meaning it meets the requirments of IP54.
