3.11.5.2
Power-Installed Screw Foundations

bolt and top plate dimensions may be utilized. Screw foundations shall be

LIGHTING
**************************************************************************
NOTE: Following a power outage, a minimum of 10.8
lux (1 foot candle) at grade within 30 seconds is
required. Requirement may be met by including dual
re-strike element lamps for instant re-strike, using
incandescent fixtures for backup lighting or by 5
minute UPS to allow standby power to pickup lighting
loads. When the asset being protected justifies the
additional cost, interleaving of power circuits
should be considered for additional security and
reliability. When interleaving is used, the loss of
any one circuit should not significantly reduce the
visual detection of intruders. Interleaving may
also be useful in reducing the power demand for
backup power sources.
