7、ce with the requirements herein. All parts subject to wear, breakage,or distortion shall be accessible for adjustment, replacement, and repair. The sirens shall be electric-motor-driven or electronic, and shall be complete in all details. They shall be of rugged construction towithstand vibration an
8、d exposure to severe weather conditions without excessive deterioration and shallbe capable of operating after long periods of nonuse. The sirens shall be constructed so that dust,water, and condensation within the unit will be at a minimum. Openings shall be screened to prevent theentrance of anima
9、ls and larger insects.3.2 Components. The siren shall include, as a minimum, the following components:3.2.1 Housing. The motor-driven siren or electronic siren speaker housing shall be constructed ofpowder coat painted sheet metal, color-impregnated fiberglass, fiberglass-reinforced moldedpolycarbon
10、ate resin, or aluminum (electronic siren speakers only). For sheet metal, all joints shall beriveted or welded securely, except bolts that shall be used to fasten portions made removable forinspection and maintenance of the interior mechanism. Sheet metal screws shall not be used. Fiberglassand poly
11、carbonate housings shall be drilled and shall be securely bolted to the supporting framework.3.2.2 Mounting. A base shall be provided for mounting the siren on a flat, horizontal surface; orbrackets for a slant roof or pole mount.3.2.3 Fan and stator (motor-driven sirens only). The fan and stator fo
12、r motor-driven sirens shall bemade of aluminum. The fan and other rotating parts of the siren shall be in static and dynamic balance. The fan shall be fastened securely to the motor shaft and a key shall be used to prevent slipping. Bafflesshall be provided within the housing, or the design of the s
13、tator and housing shall be such that the inputair is prevented from mixing with the output air.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-5941433.2.4 Code transmitter.
