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. 2. The enclosure shall have separate, isolated wiring compartments for line voltage wiring and Class 2 wiring. 3. The Group Controller shall provide individual terminals for each neutral for mains input and each motor. 4. The Group Controller shall provide a grounding bar to land each ground of mains input and each motor. 5. The Group Controller shall provide keyed mounting features so that mounting screws do not need to be removed. C. ELECTRICAL 1. The Group Controller shall operate at 110 to 127 VAC, 50 Hz or 60 Hz. Voltages are referenced to Neutral. 2. Each channel on the Group Controller shall be rated for 5 amperes, ¼ hp motor load at 120 VAC, 60Hz with a lifetime greater than or equal to 10,000 cycles. 3.
