A U D I B L E / V I S I B L E N O T I F I C A T I O N SpectrAlert® Dual Strobe Notification Appliances Models Available DS2475WAR White Housing Red Housing DS2475WAR DS2475RAR DS2475RAR Accessories White Housing Red Housing BBS-DSW BBS-DSR Product Overview Two visible signals for multiple applications from one device System Sensor’s SpectrAlert Dual Strobe notification appliance is designed to accommodate unique signaling applications where two stage notification is required. Meets unique applications where combinations of amber and red lens colors are required Flexibility. The SpectrAlert Dual Strobe line incorporates two visible notification Strobes may be powered over a two or four wire circuit 75 candela output per UL 1638 Low current draw Mounts to single gang and four square back boxes Field-reversible strobes for left- or rightmounting Multiple labeling options included appliances, to accommodate those applications where a two stage alarm system or two distinct visible signals are required. Available in white or red housings and a variety of colored lens options, SpectrAlert Dual Strobes allow a user to customize visible notification for both fire and non-fire applications including pre-action alarms, security, tornado alert, evacuation, etc. Performance. Based upon the principles of the original SpectrAlert wall mount strobes, the Dual Strobe models operate at 24 volts, and provide 75 candela output per UL 1638. The strobes may either be powered in tandem over a two wire circuit or independently over a four wire circuit. Installation. Like all SpectrAlerts, the Dual Strobes offer installation ease and flexibility. These models are typically mounted to a single gang back box. Using the mounting bracket provided, four square back box mounting is also accommodated. Customization. SpectrAlert Dual Strobes provide the flexibility to customize the product in the field. If desired, the strobe modules can be field-reversed, for left or right-mounting of each colored strobe. Multiple labeling options are provided, including FIRE, ALERT, EVAC and EVACUATE, to designate the specific function for each strobe.
