American Response Vehicles <br />44 <br /> <br />The "Gain control" switch will turn the siren ON and OFF as well as control the volume of the PA (Public <br />Address) and RADIO repeat amplification. The siren will be warranted by the device manufacturer for a period <br />of two (1) year on labor and two (2) years on parts. Exact details of the device warranty will be submitted at the <br />post award conference. <br /> <br />SIREN SPEAKERS: A pair of Federal ES 100 siren speakers will be installed. Each speaker will have a 100 watt <br />driver and will emit through the cast aluminum horn. The speaker will be mounted in a bracket behind the <br />OEM bumper with a Stainless steel face plate attached to the front of the bumper. The edges of each hole, in <br />the bumper, will be clean and will have rust preventative treatment, prior to final installation of the <br />speakers. The siren and speakers will meet or exceed current Federal KKK-A-1822. <br /> <br />SIREN OR HORN SELECTOR SWITCH: The OEM horn ring will control the OEM electric horn and the siren's <br />manual momentary input controls. A switch will connect the horn ring to either the OEM HORN or to the <br />SIREN. The switch will be located in the cab console's switch panel. The switch legend, that clearly defines the <br />switch function will be engraved in the switch panel. The legend will be illuminated when the head light <br />switch is on. <br /> <br />AIR HORN SYSTEM: The apparatus will be supplied with an authoritative sounding air horn system that is loud <br />enough to overwhelm almost every usual audible distraction. The air horns will, when enabled, emit a loud <br />(128 decibel) signal with tremendous power for the duration of the users' depression of the Activation switch <br />or momentary mechanical valve. The system will contain two horns of EQUAL length. <br /> <br />AIR HORN ACTIVATION: The air horns will be activated through a manually activated momentary air valve with <br />a pull down lanyard cable. The valve will feature an orifice size large enough to allow 22 CFM of air volume to <br />pass through at ninety pounds per square inch of pressure. The valve will be activated manually by a pull down <br />cable type lanyard. The valve will automatically shut off when the lanyard is released. <br /> <br />AIR HORN ACTIVATION: The air horns will be activated through a twelve volt solenoid valve. The solenoid valve <br />will feature an orifice size large enough to allow 22 CFM of air volume to pass through at ninety pounds per <br />square inch of pressure. The solenoid valve will be activated by a momentary foot switch. The solenoid valve <br />will automatically shut off when the foot switch is released. The foot switch will not activate (Blow) the air <br />horns, unless BOTH cab doors are closed. This is designed to prevent accidental discharge of the air horns. <br /> <br />AIR HORNS: Two Grover model No 1510 "Stutter Tone" air horns will be supplied and installed at the location <br />specified below. Each horn will feature a mounting pedestal that is cast onto the sound unit and a bell support <br />bracket located at a forward position on the horn bell. The front bracket will feature a rubber insulator at the <br />contact points to prevent finish damage to the bell and to minimize bell vibration. An air passage designed to <br />deliver air flow to the sound unit diaphragm will be drilled into the pedestal with an NPT thread at the base for <br />air line fitting installation. Exposed air line or air line fittings are not acceptable. Each horn bell will measure <br />twenty five inches long. Each horn will emit a 128 decibel sound blast measured at five feet from the horn bell <br />at 200 MHz (megahertz). The horns will function adequately at a minimum air pressure of sixty (60) and a
