New Fairfield upgraded its 911 system this week. It was done as part of a statewide project that enhances the equipment of all public safety answering points across Connecticut.  The new system should provide better inter-operability between towns when transferring calls, a better mapping system, enhanced GPS tracking, and automatic reroute in the unlikely event that the Town system goes down.  New Fairfield officials say all of the dispatchers have received formal training on the new system.  The cost of the training is reimbursable by the state.  The cost of the upgrade to the Town was minimal with the State picking up the bulk of cost.
