System Sensor SP2C24177 SpectrAlert White Ceiling-Mount Speaker With Built-in 24 Volt 177 Candela Strobe

System Sensor's SpectrAlert SP2C series ceiling speaker/strobes represent the combination of leading-edge strobe and speaker technology with a design specifically intended for ceiling mount applications.

Technology.
SpectrAlert SP2C ceiling speaker/strobes combine the low current draw of the ceiling mount SpectrAlert strobes, with the intelligible, fidelity sound quality of the SpectrAlert SP200 series evacuation speaker.

Flexibility.
Like all SpectrAlert products, the SP2C series ceiling speaker/strobes feature the flexibility to meet a wide variety of applications. The 24 volt strobe is available in seven different candelas, including 177 candela for sleeping areas. The speaker offers field-selectable 25.0/70.7 voltage and 1.4, 1.2, 1, and 2 watt power taps.

Aesthetics.
The SP2C ceiling speaker/strobes offer a design that is sensitive to the aesthetic demands of ceiling mount applications. The round shape maintains a low profile appearance, similar to that of a smoke detector. Its stylish curves and design further refine the aesthetics over other generic wall/ceiling mount designs. Yet SpectrAlert's round shape provides clearly visible "FIRE" identification from all angles.

Installation.
The SP2C ceiling speaker/strobes include several features to simplify installation. By incorporating the SP200 series speaker, the entire unit may be mounted to a 4" x 4" x 21/8" back box, without the need for an extension ring. An optional back box skirt is also available for surface-mount applications. And with SpectrAlert's round shape, it is not necessary to align the back box with the room's walls. SpectrAlert always lines up.
