Emergency Oxygen Supply Connection

Description

Specification Information

The Emergency Oxygen Supply Connection (EOSC) provides an inlet for connecting a temporary auxiliary source to the oxygen pipeline system for emergency or maintenance situations as required by National Fire Protection Association (NFPA) 99. The inlet consists of either a 1″ (25mm) ball valve, with 1/2″ and 1″ National Pipe Thread Female (NPTF) connections or a 2″ (50mm) ball valve, with 1-1/2″ and 2″ NPTF connections and a pressure gauge housed in a weather-tight enclosure. The front of the enclosure will be permanently labeled “Emergency Oxygen Supply Connection” for easy identification and provided with a padlock staple to prevent unauthorized access. Two enclosures are available: The recessed mount enclosure is provided with a tubing extension directly out of the rear of the enclosure.

The Surface Mount enclosure is provided with the tubing extension from the right side of the enclosure. Both enclosures are 14-gauge, cold rolled steel with a gray white polyester powder coat finish. The Emergency Oxygen Supply Connection is to be connected per NFPA 99. For the piping schematic and dimensions see pages 2 and 3. Check valves are available to complete the installation as required by NFPA 99. For check valve product details, see BeaconMedaes specification sheets SSB-810-03 and SSB-810-02. Relief valves are pre-set at 75 psi (517 kPa). The relief valve is a brass body, single-seat design, cleaned for oxygen use. It automatically re-seats to provide a bubble-tight seal after operation.
