GENERAL DESCRIPTION
The K1670-1 Automatic Start/Stop Arc Sensor can be

connected extraction fan when it detects the arc flash,
and off (after a 20 second delay) after the arc stops.
If installed on a Mobiflex 200-M system with a
K1669-1 Lamp Kit, the Sensor will control the opera-
tion of the Mobiflex 200-M extraction fan.
If installed on a wall-mounted system including
SF2400 Fan with a K1669-2 Lamp Kit, the Sensor will
control the operation of the SF2400 Fan.

mounted system, refer to the SF2400 Fan manual.
