SpectrAlert Advance, the broadest and most versatile line of notification devices available, includes a wide range of devices to meet mass notification application requirements. ALERT-printed on white housings, SW-ALERT, SWH-ALERT and SPSW-ALERT amber lens strobes and speaker strobes provide visual signaling for mass notification in compliance with ANSI/UL 1638 Standard for General Signaling Visible Appliances. Other ALERT-printed models provide clear lenses for use with color lens strobe attachments (amber, blue, green, and red) that easily attach to strobe and speaker strobe devices without a candela derating. In addition, SpectrAlert Advance mass notification devices include plain (non-printed) strobes, horn strobes and speaker strobes. These devices, along with ALERT-printed devices and SpectrAlert Advance accessories, can meet a wide range of requirements for indoor and outdoor applications, including mass notification, general signaling, severe weather and emergency response. All SpectrAlert Advance mass notification and general signaling devices are compatible with the entire SpectrAlert Advance and include all the same time- and money-saving innovations. For example, plug-in designs simplify installation and reduce costly ground faults; universal mounting plates with onboard shorting springs test wiring continuity to speed installation and protect devices from damage; and field-selectable settings provide versatility and enable installers to quickly set each device to meet application requirements.
