sufficient for approximately 7 minutes breathing. Four bottles were in 

 the crew quarters and two each were in the bridge and equipment room. 

 None was required in the wet room since scuba gear stored there could 

 serve the same purpose. 



COMMUNICATION, ELECTRICAL, AND SANITARY SYSTEMS 



The communications system (Table 2) provided voice and visual communica- 

 tion between the habitat and the support center. The bridge, which was 

 the habitat communication center, was connected to the surface command 

 facility via intercom and sound-powered phone. Each compartment was 

 equipped with an intercom station connecting it with the other compart- 

 ments and the surface, an open mike and closed-circuit television camera 

 for the behavioral program, and audio and visual alarms. The bridge con- 

 sole could monitor the open mikes and the closed-circuit television 

 cameras in each of the other compartments . 



Electrical power was supplied to the habitat via a power cable contained 

 within the lambilical bundle, from a variety of diesel generators at the 

 surface support center. The habitat electrical system was a three-wire 

 grounded system. The main power panel was located in the equipment com- 

 partment, and separate circuit breakers were provided in each compartment. 

 Two flood valves were provided in the wet room, one at the hatchway level 

 which set off a flood alarm, the other higher up on the wet room bulkhead 

 tripped surface power when activated. Emergency battery-powered lamps in 

 each compartment were activated when a power fialure occurred.
