A communication module for an asset to be monitored operates to periodically receive a signal from a monitoring facility via a first wireless communication system, and in response to the absence of the signal at an expected time, communicating with the module via a second wireless system. Also, a method of mounting a distribution box to a duct, at a distribution point that is spaced-apart from duct ends, may include positioning a distribution point duct section in the distribution box, and hermetically sealing a distribution chamber, defined within the distribution box, from an environment of the distribution box. The body comprises friction material and the coil is adapted for cooperating and pretensioned engagement with the body in order to provide a pivotal connection with a controlled friction resistance to turning of the pivot.
