NOTES
The DCB option uses a quartz T-4 double contact bayonet base
lamp to provide emergency light during power outages. The
DCB socket must be field wired into an auxiliary emergency
power supply circuit for emergency use.
The QR option uses a quartz T-4 double contact bayonet base
lamp to provide light continuously during cold start or hot
restrike until the HID lamp is at approximately 25-50% or more
of its rated light output.
When ordering a sloped ceiling adapter, specify the degree
of slope in 5° increments (max of 35°). For a more precise
degree or wet ceiling application, please contact factory. The
SCA must be installed during housing installation.
