Hawaiian TelCom Central Offices – Oahu, HI

This is an on going project that has so far required single zone to static pressure control conversion at 28 mission-critical central switching offices, including the installation of Honeywell Variable Frequency Drives, Power Meters, Zone Dampers, Actuators, and Temperature Sensors. The replacement of existing Andover control system included HVAC, door security, and environmental alarms at all sites. All site JACEs have been linked to a central supervisor and all alarms routed to HT’s network operations center. Sites that have been converted averaged a savings of xx%  and have resulted in an overall savings for Hawaiian Telcom of $xx..xx over the project timeline. Phase 2 is in the planning stage with Neighbor Island and smaller Oahu sites targeted for Andover to Honeywell conversion.
