Abstract: The present disclosure generally relates to methods for sending event notifications. In some examples, a controller periodically sends messages concerning a status of an event corresponding to the controller. In some examples, at a first time while periodically sending the messages and in accordance with a determination that the status of the event has changed, the controller sends a message concerning data other than the status of the event. In some examples, at the first time while periodically sending the messages and in accordance with a determination that the status of the event has not changed, the controller continues to periodically send the messages without sending the message concerning data other than the status of the event.

Abstract: An improved composite material is prepared by first uniformly mixing cement and perlite fines. The perlite fines comprise particles that are less than 200 mesh. The mixture of perlite fines and cement is then mixed with water, formed into a desired shaped, and allowed to dry. The dried material is useful in many applications where cement is used and has fireproofing and strength characteristics superior to ordinary concrete.

Abstract: A cementitious panel is provided with spaced inner and outer surfaces connected by edge surfaces. A waterproof film forms longitudinally extending cavities within the panel, with the cavities being laterally spaced from each other and spaced from the inner, outer and edge surfaces of the panel. Expanded lightweight, inert granular material substantially fills the cavities, and a suitable film closes off the ends of the cavities.When necessary or desirable, the panels are temporarily secured in position adjacent a member and in end to end relation to enclose it and provide fire protection. Holes are drilled through the panels at predetermined locations, and metal studs are inserted through the panel to contact the enclosed metal member and the stud is the welded to the member so that the end of the stud projects outwardly beyond the panel surface. The panels are then secured to the stud end projecting therethrough to enclose and provide fire protection to the member within the positioned panels.
