System Sensor P4RK 4 Wire Outdoor Horn-Strobe Standard CD, Red

The System Sensor SpectrAlert Advance P4RK is a red, four-wire, outdoor horn strobe with selectable strobe settings of 15, 15/75, 30, 75, 95, 110 and 115 cd. The SpectrAlert Advance series offers the broadest line of outdoor speakers and speaker strobes in the industry. From metal and plastic outdoor back boxes to white and red plastic housings, to wall and ceiling mounting options, SpectrAlert Advance can meet virtually any application requirement. SpectrAlert Advance outdoor speakers and speaker strobes can be used indoors or outdoors in wet or dry applications and can provide reliable operation from -40 degrees F to 151 degrees F. In addition, these speakers provide a broad frequency response range, low harmonic distortion, and maintain a high sound pressure level at all tap settings to provide accurate and intelligible broadcast of evacuation messages. The entire SpectrAlert Advance line, including speakers, provides a plug-in design that reduces ground faults by enabling installers to pre-wire mounting plates and dress the wires before plugging in the speakers. To enable faster installation times, a shorting spring on the mounting plate provides instant feedback to ensure that the wiring is properly connected. Furthermore, rotary switches simplify the selection of voltage and power settings. Both wall and ceiling speaker strobes include field-selectable candela settings that enable installers to quickly set each device to meet application requirements. The speakers' weatherproof plastic back boxes (shipped with the product) and metal back boxes (available separately) are designed to accommodate in-and-out wiring for daisy-chaining outdoor devices. Plastic back boxes feature removable side flanges and improved resistance to saltwater corrosion. The screw-hole knock-outs located on the back of the back box eliminate the need to drill holes for screw-in mounting. Both weatherproof back boxes come with a 3/4-inch top and bottom conduit entries and 3/4-inch knock-outs at the back. Included with each back box is a screw-in NPT plug with an O-ring gasket for a water-tight seal.
