The Model LC200 consists of an electronic
control and an electronic light sensor interact­ing. The unit offers separate control of two
lighting zones, each with user settable on/off
light level setpoints. The Electronic control

a contact closure from any TORK Timer(s),
or existing EMS system to provide for inde­pendent time-of-day override if required.

Features:

• Single electronic light sensor with swivel

(Model EPC-1) which can be mounted up
to 1000 feet from controller

• Dual outputs with independent adjustment

from 2 to 100 footcandles

• Two independent “Time-of-Day” inputs

• 30 second delay on start-up

• Power-On status indicator

• Load status indication for each load
