MJW Consolidated has completed major fire protection upgrades and modifications to a Delta Airlines facility in Atlanta Georgia. Delta’s TOC 2 facility is roughly a 220,000 square foot aircraft hangar comprised of 5 operating bays and ancillary support areas. MJW upgraded the facility by replacing valves, fire detection system, and controls of the 24 existing fire protection systems protecting the aircraft service area.

The mechanical work involved modification of piping systems to accommodate installation of new deluge valves and related trim with greater system control capabilities.

The fire alarm and detection work required extensive modifications of the releasing system, including installation and programming of a new Det-Tronics EQP Panel, installation of new triple spectrum infra-red flame detectors, relocation of the existing linear heat control panel, and installation of new manual releasing and abort stations.

The new Det-Tronics EQP served as the back bone for an independent multi-zone release system for the entire hanger. The EQP monitors 360 points including multiple points for control valves, flow switches, foam pumps and low system air pressure.

The new triple spectrum infra-red detectors are arranged in a dual release configuration that adds to the system stability and reduces the likelihood of false trips. The system is equipped with dead-man type abort stations uniquely configured for each hangar bay.
