The time clock and scheduling setting shall be coordinated with the owner prior to inception of work. The lighting control shall interface with the fire alarm system such that in an alarm condition the emergency shall automatically turn on to full output and override the system settings. In the event of a normal power failure the life safety lighting shall automatically turn on and shall override the lighting control settings. New emergency life safety lighting and exit signs are being added. The receptacles and HVAC system in the main telecom room shall be added to the emergency power distribution system.
