b) Ensure that each remote warning system will produce a warning signal throughout <br />360 degrees, unless a proposed site location is best served with a directional siren. If <br />a directional siren is proposed for a site, it will be clearly identified and justified. <br />1.2.3 Siren Control Cabinet: <br />a) Ensure that the control unit cabinets are furnished in a natural finish aluminum, or <br />stainless steel, with materials offering a high resistance to rust and corrosion. The <br />Contractor assures that the cabinets are maintenance free, with exception of periodic <br />lubrication of hinges and locking mechanisms. <br />b) Ensure that all ventilation louvers are screened to the interior of the cabinet to prevent <br />entry of insects, wasps, and other pests. <br />c) Provide a control cabinet enclosure that is equipped with a lift hook to facilitate <br />installation of the cabinet. All control cabinets will be mounted on the pole in such a <br />manner that the bottom of the cabinet is twelve to fifteen (12 - 15) feet above the <br />surface of the ground. <br />d) Ensure that the cabinet mounting system has sufficient strength to support the entire <br />weight of the cabinet including all modules, accessories, and other contents. The <br />cabinet will be designed and constructed to withstand high winds, rain, hail, snow, <br />etc. without damage to the cabinet. <br />e) Provide modular system electronics. System modules will either plug into a back <br />plane or installed on hinged panels that swing open for service. The individual <br />modules will be designed, constructed, and installed to permit testing while in <br />operation. <br />f) Supply all cabinets with modules already installed including City supplied radio <br />equipment as specified in Article 2. <br />1.2.4 Poles: <br />a) Warrant that the work on the System includes materials and installation of poles to <br />mount the sirens and ancillary equipment at no additional charge to the City. <br />b) During the site evaluation, determine the acceptability of using an existing pole and <br />the location for the design sound distribution based on the City's recommendation to <br />use an existing pole in the area of a proposed location. <br />Outdoor Siren Warning System Agreement 6/2012 <br />7 <br />
