4 1.0 General 1.1 Scope This specification covers the physical, electrical, environmental and operating requirements for photoelectric controllers (PECs) used for the control of individual street light luminaires, street light relays and street light circuits. It is not intended that this specification restrict bidder's ideas, inventions, advances in the state of the art, or technological improvement, and therefore all bids will be given careful consideration. It must be noted, however, that the City of Ottawa or its agent requires sufficient explanations and descriptions to be able to make a good value judgement. Any variation from the requirements of this specification shall be quoted as additional bids. This specification section shall be read in conjunction with engineering specification LGC Reference Standards The photoelectric controllers supplied shall meet or exceed all applicable requirements in the latest issue of the following standards: ANSI C UL 773 Locking Type Photo-control Devices and Mating Receptacles, Physical and Electrical Interchangeability and Testing Plug-in, Locking Type Photo-controls for Use with Area Lighting 3.0 Approval of Source PECs shall be supplied only by manufacturers approved by the City of Ottawa or its agent. Only PECs evaluated and approved before submission of a quotation will be accepted. Once approved, the manufacturer shall not change the material type or component parts without prior approval for subsequent orders. 4.0 Physical Characteristics 4.1 Size and weight 4.2 Plug 4.3 Case a) Outside diameter of the base (90 mm or less) b) Height above socket when mounted (60 mm or less) c) Net weight (250 g or less) To fit standard EEI-NEMA three terminal locking type receptacle. The plug blades shall be composed of solid brass. For City of Ottawa Use Only LAS0001 Rev.2 Page 4 of 7

5 a) High impact resistant plastic cover to protect against weather-induced electrical or mechanical malfunction. Cover to be complete with a neoprene or cross linked polyethylene gasket. b) Colour (grey or clear for 120 V types) c) The assembled PEC shall pass the resistance to impact test described in UL Window Clear acrylic with an ultraviolet inhibitor to impede discoloration. 5.0 Electrical Characteristics 5.1 Supply voltage 120 V 60 Hz (105 V to 130 V operating range) 5.2 Load Capacity 1000 W incandescent or 1800 V A ballast type loads 5.3 Dielectric Strength and Lightning Protection 5 kv minimum dielectric strength between any current carrying part and the metal mounting surface. Surge protection shall consist of a metal-oxide varistor (MOV) wired line to neutral. The MOV shall have at 160 J, at 6500 A and at 320 V RMS rating. The clamping voltage shall be a maximum of 810V. 5.4 Photoelectric Sensor Shall be cadmium sulphide (CdS) cell, hermetically sealed to prevent damage due to moisture and industrial pollutants. 5.5 Relay Electronically controlled heavy duty, quick-response DC electromagnetic relay. 6.0 Environmental Characteristics 6.1 Temperature Range -40 o C to 65 o C. 6.2 Humidity Operate normally at 96% relative humidity. 6.3 Weatherproof Mounting For City of Ottawa Use Only LAS0001 Rev.2 Page 5 of 7

6 When properly attached to its mounting receptacle, the PEC neoprene or cross-linked polyethylene gasket shall prevent beating rain, snow, dust and insects from entering the receptacle. 6.4 Waterproof Case Shall remain operative when subjected to water delivered at an angle of 45º to the vertical in the direction(s) most likely to cause water to enter. 7.0 Operating Characteristics 7.1 Factory Set Points a) Turn-on 1.0 fc (+/-20%) nominal, 2.0 fc max b) Turn off 4.5 fc max c) Ratio Off/On 3:1 nominal 7.2 Failure Mode Fail "ON" contacts (i.e. normally closed) unless otherwise specified in the purchase inquiry. 7.3 Time Delay Turn-on time delay shall be less than 1 second; turn-off delay shall be less than 5 seconds. 7.4 Rated Life 5000 "On-Off" operations minimum at rated load with no chattering of the relay contacts upon opening and closing. 8.0 Marking 8.1 The base of the PEC shall be clearly and permanently marked with voltage and load rating of the device. 8.2 A nameplate shall be affixed to the base of the PEC showing the manufacturer s name or trademark, catalogue number that specifically defines the device, and the date of manufacture. 8.3 Provision for date coding (year and month of installation) shall be permanently moulded into the base of the PEC. 9.0 Information Supplied To The Bidders The following minimum information will be supplied to the bidder when requesting a quotation: a) Quantity b) Turn-on level, if other than as specified in Section 7 c) Failure mode, if other than as specified in Section 7 d) Lightning arrester option, if other than as specified in Section 5 e) Photo-electric sensor type, if other than specified in Section 5 f) Circuitry, if other than as specified in Section 5 For City of Ottawa Use Only LAS0001 Rev.2 Page 6 of 7

7 10.0 Instructions to Bidders 10.1 General Suppliers shall submit with their quotations the technical information requested herein. Suppliers who fail to provide the information requested might have their quotations rejected as incomplete Technical Information Requested a) Manufacturer's reference: catalogue number of the PEC b) Power consumption of device: when contacts open and when contacts closed c) Average rated life d) Quality control plan to ensure compliance of the products with this specification 10.3 Samples If requested, the supplier shall provide a sample identical in every way to the units being tendered. Samples will be returned to the supplier after evaluation Packaging And Shipment Each PEC shall be individually packaged in a carton that will identify and protect it during handling after it is removed from the shipping carton. All shipping charges shall be the responsibility of the supplier and the supplier shall obtain approval from the City of Ottawa or its agent prior to shipment Manufacturing Inspections The City of Ottawa or its agent reserves the right to request and be granted permission to visit the manufacturer's plant to inspect the photo-electric controllers and manufacturing methods during assembly and testing Warranty Manufacturers shall warrant that the photoelectric controllers furnished by them conform to all requirements and conditions of this specification. The manufacture shall remedy, at no expense to the City of Ottawa or its agent, defects due to faulty workmanship, material or design for a period of four years after installation, but in no case for more than five years after receipt of the unit by the purchaser. Any additional improvements in the warranty conditions shall be stated with the quotation. For City of Ottawa Use Only LAS0001 Rev.2 Page 7 of 7
