With the glass element, this will need replacing once activated in order for the call point to be used again. With the plastic option, there is no need for replacing it. The Universal Fulleon Call Point is supplied with a key which will reset the unit, as well as test it and allow the removal of the front cover. The call point features an LED alarm indicator too, and comes with a back box and fixing screws for either mounting flush with, or on the surface of, a wall.
