MONITORING SYSTEM FOR A CENTRAL VACUUM ASSEMBLY

摘要

A service network, and associated methods, for monitoring central vacuum assemblies at distinct sites that include one or more air flow meters at each distinct site, each air flow meter respectively positioned and adapted to measure an indicia of air flow in connection with a particular central vacuum assembly within the service network; interfaces at the distinct sites associated with each air flow meter to relay an abnormal result from the respective air flow meter; and an off-site service center in communication with the interfaces at the distinct sites to register the abnormal result and identify the site of the abnormal result.
