without damage or loss of memory.
F. Manufacturer shall provide software to simplify the design and installation of all lighting
controls.
G. Manufacturer shall be Year 2000 compliant for both their corporate operating systems
and lighting control products.
1.07 PROJECT/SITE CONDITIONS
A. Motorized Window Treatment controls shall operate in an ambient temperature range of
0°C (32°F) to 40°C (104°F) and 90% non-condensing relative humidity.
B. Existing Conditions
1.08 WARRANTY
The manufacturer shall provide a one-year limited warranty on all equipment supplied. The
warranty shall cover 100% of the cost to repair any or replace any parts required over the first
year, which are directly attributable to the manufacturer. Warranty coverage shall begin three
months from date of delivery.
1.09 MAINTENANCE
The manufacturer shall make available to the end user a method of ordering new equipment for
expansions, replacement, or parts to be used as spares twenty-four hours a day, seven days a
week. The manufacturer must make available new or remanufactured parts for a minimum period
of ten years from the final date of commissioning.
PART 2 PRODUCTS
2.01 ACCEPTABLE MANUFACTURERS
1. LUTRON
2. The listing of a manufacturer as "acceptable" does not imply automatic approval. It is the
sole responsibility of the electrical contractor to ensure that any price quotations received
and submittals made are for products/systems that meet or exceed the specifications
included herein.
2.02 AC MOTOR GROUP CONTROLLER
A. GENERAL
1. The Group Controller shall provide open, close, and stop operation of up to four
ac motorized window treatments.
2. The Group Controller shall be capable of being controlled via dry contact closure
inputs.
3. The Group Controller shall be capable of receiving either momentary or
maintained dry contact closure inputs. This function shall be configurable by a
switch.
4. The Group Controller shall be capable of individual zone control and/or master
control from the contact closure inputs.
5. Stopping the motor shall be accomplished either by providing a dry contact
closure to the “Stop” terminal or by applying contact closures to the “Open” and
“Close” terminals simultaneously.
6. The Group Controller shall provide means for reversing motor direction for a given
input in the event of a miswire without removing power from the unit. The motor
direction shall be configurable by a switch.
7. The Group Controller shall provide local override buttons that activate the window
treatments for wiring verification.
8. The Group Controller shall provide LED indication as to the last state of the
window treatment.
B. MECHANICAL
1. The Group Controller shall be housed in a metal enclosure capable of being
surface mounted in any orientation.
