Specifications
LC8 Controller
Each Controller shall be powered by 24 V , and
have separate high and low fully adjustable
setpoints. Signal/setpoint and relay status indication
shall be provided along with calibration input for
adjustment. The controller shall be enclosed in a
plastic enclosure for surface mounting installation.
The controller shall provide a 10 A low voltage Form
C relay output.
• Dead Band: Adjustable - 5-95%
• Input Delay: Standard - 30 second Sensor
(removable for adjustment)
• Output: Standard - Form C SPDT Relay
10 A resistive
• Circuit Board: 3.75” H x 2.25” W x 1” D
• Plastic Box Dim.: 4.75” H x 2.25” W x 1.5” D
CES Sensors
The photoelectric device shall be a Class 2, low-
voltage, ambient light sensor designed to interface
directly with the analog input of the Lighting Control
System. The sensor shall supply an analog signal to
the EMS system proportional to the light measured.
The sensor output shall provide for zero or offset
based signal. The sensor shall be capable of a fully
adjustable response in the range between 0 and
10,000 foot candles with a +/-1% accuracy at 70 °F
(21 °C).
The sensitivity adjustment shall be at the sensor
body, and outside of the sensor’s viewing angle. The
sensor housing shall be constructed from GE
Cycolac (R) ABS, shall be flame retardant and meet
UL 94 HB standards.
Indoor
Indoor sensors shall have a Fresnel lens, with a 60
degree cone of response. Indoor sensors shall only
require a penetration hole in the ceiling of 3/8 inch
dia., and the sensor shall mount to the ceiling using
adhesive tape. The indoor sensor range shall be
between 0 and 750 FC.
Outdoor
Outdoor models shall have a hood over the aperture
to shield the sensor from direct sunlight. The
outdoor sensor circuitry shall be completely
encased in an optically clear epoxy resin. Outdoor
sensors shall mount to a standard threaded 1/2 inch
conduit or fit a 1/2 inch knockout. The Outdoor
sensor range shall be between 0 and 750 FC.
Atrium or Skylight
The Atrium or Skylight sensors shall have a
translucent dome with a 180 degree field of view.
Atrium or Skylight sensors shall mount to standard
threaded 1/2 inch conduit or fit a 1/2 inch knockout.
Atrium sensor range shall be from 2 to 2,500 FC.
Skylight sensor range shall be between 10 and
7,500 FC.
Environment
• Operating temperature: 13 – 140 °F (-11 – 60 °C).
• All CES sensors are water-resistant and designed to
withstand UV radiation.
• LC8 Controller and PP Power Packs for indoor use
only.
