Check the listing for details. System Sensor SRK Strobe Red W/ Backbox. Condition: New. Listed at 85.00 USD. System Sensor SRK Strobe Red W/ Backbox SpectrAlert Advance offers the broadest line of outdoor horns, strobes, as well as horn strobes in the industry. Besides, with white or red plastic housings, wall or ceiling mounting options, and plain or FIRE-printed devices, System Sensor SRK can meet virtually any application requirement, including indoor, outdoor, wet, and dry applications in temperatures from −40°F to 151°F. Like the entire SpectrAlert Advance line, outdoor horns, strobes, and horn strobes for wall applications include a variety of features that increase application flexibility and simplify installation. First, field-selectable settings, including candela, automatic selection of 12- or 24-volt operation, horn tones, together with three volume options enable installers to easily adapt devices to meet requirements. Next, System Sensor SRK devices use a universal mounting plate for both wall and ceiling applications. This mounting plate includes an onboard shorting spring that ensures wiring continuity before devices are installed, so installers can verify proper wiring without mounting the devices and exposing them to potential construction damage. Once the plates are mounted, all SpectrAlert Advance devices utilize a plug-in design with a single captured screw to speed installation and virtually eliminate costly ground faults.
