The ITAL is a unidirectional light with one or two 150 W lamps depending upon the application. It may be used for any category ICAO or military runway and for FAA CAT I runways. How to Order: Select the basic catalog number for the application from Table A on the following page. Add symbols for options as required. Order separately a single isolation transformer and a mounting base. See beam orientation diagram on following pages. Features Example: 850EA-B-2-150-R-S-A is a unidirectional red runway end light with one operating 150 W lamp and one standby 150 W lamp. Upon failure of the first lamp, power is automatically transferred to the spare lamp. The light operates on a single 150 or 200 W isolation transformer powered by a series circuit. Meets USAF and ICAO photometric requirements for threshold, end and approach lighting systems 850EA – B – Metallic-Ceramic Coating for greatly increased corrosion resistance Fixture Type: Common Optical System for all applications Model: Dual-Light Channels with narrow windows Center Rib between windows resists military tailhook damage One-Piece 12-inch Casting resists snowplow damage Soft-Mount Optical System to resist shock damage Pressure Tested for watertightness Single Plug Lead Assembly for use with one isolation transformer Optional Standby Lamp Transfer to reduce light maintenance for single lamp applications (Option - A) Optional High Strength Casting: approximately 2 times the tensile strength of ductile iron – – – – Base Size: B=11.25-inch Bolt Circle Number of Lamps: 1=1 x Lamp 20710 6.6 A 2=2 x Lamp 20710 6.6 A Operating Wattage: 150=1 x 150 W** 300=2 x 150 W Color: C=Clear G = Green Beam Orientation: L2=Left Toe-in 2 degree R2=Right Toe-in 2degree S=Straight 0 degree R = Red L3 = Left Toe-in 3.5 degree R3 = Right Toe-in 3.5degree Options: NM=High-Strength Casting A=Standby Lamp (Series Circuit): Energizes standby lamp upon failure of operating 150 W lamp.** 3.28 *Crouse-Hinds catalog number 850EA-B-1-150-G-S and 850EA-B-150-R-S only. **For Option A, select basic catalog number 850EA-B-2-150-X-XX-A. www.chalp.com Technical Data Table A Compliance ICAO NATO USAF FAA Application** Color Catalog Number*** Threshold Green 850EA-B-2-300-☆-3 Threshold: Wing Bar Green 850EA-B-2-300-☆-2 Runway End Red 850EA-B-1-150-R-S Approach: Centerline Barrette Clear 850EA-B-2-300-C-S Approach: Side Row Barrette Red 850EA-B-2-300-R-☆-2 Threshold* Green 850EA-B-2-300-G-S Runway End Red 850EA-B-1-150-R-S Approach: Centerline Barrette Clear 850EA-B-2-300-C-S Approach: Terminating Bar Red 850EA-B-2-300-R-S Approach: Inboard Wing Bar Red 850EA-B-2-300-R-S Approach: Side Row Barrette Red 850EA-B-2-300-R-S Threshold* Green 850EA-B-2-300-G-S Runway End Red 850EA-B-1-150-R-S Approach: Centerline Barrette Clear 850EA-B-2-300-C-S Approach: Terminating Bar Red 850EA-B-2-300-R-☆-2 Approach: Pre-Threshold Bar Red 850EA-B-2-300-R-☆-2 Approach: Side Row Barrette Red 850EA-B-2-300-R-☆-2 Threshold*: Category I Green 850EA-B-1-150-G-S Runway End Red 850EA-B-1-150-R-S *Includes Wing Bars. **If the runway category is not noted, then the catalog number is used for all applicable categories. ***Add options as required. ☆Select equal quantities of left and right toe-in.

Only the high quality paving sealants and epoxies listed in manual 9013 are suitable for use with ITAL (Not applicable for deep base). Beam orientation is achieved by the fixture casting bolt drilling pattern. Light bases are installed with any two opposite bolt holes perpendicular to the runway centerline. The beam orientation is not field adjustable. There are two threaded holes 180° apart perpendicular to the centerline for attachment of lifting handle 19999. For FAA MALS with 240 V power, use isolation transformer 33300 for each 300 W ITAL or 33151 for each 150 W ITAL. Accessories Catalog Shipping Weight Shipping Volume Description Number Lbs Kg Cu Ft.
