B. Auxiliary Components:
1.Manual release station shall be provided at out-side the main entrance and at
Inergen bottles battery and shall, when activated, immediately release the
Inergen agent and cause immediate shutdown of power circuits.
2.Abort station (inhibit) shall be provided at out-side the main entrance and shall
,when activated, interrupt the discharge of Inergen agent and power OFF
functions. Manual release station shall override any abort station.
