Furnish and install louvers as hereinafter specified where shown on plans or as described in schedules.

Louvers shall possess stationary vertical blades designed to prevent the penetration of wind-driven rain.

Louver blades shall be contained within a 3 in. (76 mm) or 6 in. (152 mm) frame.

Louver components (heads, jambs, sill and blades) shall be factory assembled by the louver manufacturer.

Louvers shall be provided with a pressure transducer conforming to Electromagnetic Compatibility (EMC) standards EN50082-1/EN5014/EN60730-1.

Transducer shall be capable of using field-selectable pressure ranges of 0 to 0.1, 0 to 0.25, 0 to 0 0.50, 0 to 1, and 0 to 2.5 in. W.C. with accuracy within ± 0.5 in. W.C. (±12.5 Pa) and shall handle up to 10 PSID overpressure without zero shift.

Transducer output to be field-selectable: 4 to 20 mA 2-wire, 0 to 5 VDC, or 0 to 10 VDC.

Transducer shall incorporate glass-on-silicone (Gi-Si) capacitance sensor and shall be housed in a NEMA 4 enclosure.

Louver sizes too large for shipping shall be built up by the contractor from factory-assembled louver sections to provide overall sizes required.

Louver design shall limit sizes of shipped single sections to 48 x 96 in. (1,219 x 2,438 mm) and shall withstand a wind load of 20 lb per sq. ft. (0.96 kPa) (equivalent of a 90 mph [145 kph] wind - specifier may substitute any loading required).

Louver shall have extruded 6063T5 aluminum alloy construction.
