Emergency System Identification - Wiring 700.10 Emergency circuits shall be permanently marked so they will be readily
identified as a component of an emergency circuit or system by the following
methods: (1) All boxes and enclosures (including transfer switches, generators,
and power panels) for emergency circuits shall be permanently marked as a
component of an emergency circuit or system. (2) Where boxes or enclosures
are not encountered, exposed cable or raceway systems shall be permanently
marked to be identified as a component of an emergency circuit or system, at
intervals not to exceed 25 ft.
Storage Battery 700.12 (A) Storage batteries shall be of suitable rating and capacity to supply
and maintain the total load for a minimum period of 1.5 hours, without the
voltage applied to the load falling below 87.5 percent of normal. Automotive
batteries shall not be used.
Relay, Automatic Load Control A device used to set normally dimmed of normally-off switched emergency
lighting equipment to full power illumination levels in the event of loss of the
normal power supply by bypassing the dimming/switching controls, and to
return the emergency lighting equipment to normal status when the device
senses the normal supply has been restored. Such relay is required to be
ANSI/UL 924.
Conduct or Witness Test The authority having jurisdiction shall conduct or witness a test of the
complete system upon installation and periodically afterward. Article 700.3 (A)
