Litestak Sound Modules. Model LSS, 59-69dBA@10ft (69-79dBA@1m) |
|
|
Description |
• | The Federal Signal Litestak Sound Module is a microprocessorbased audible signaling device. |
|
• | The model LSS can be used as a stand-alone audible device or combined with the Federal Signal Litestak light modules to create an audible/visual signal. |
|
• | The sound module contains a microprocessor-based tone generator and an integrated speaker which produces one of 18 tones. |
|
• | Select tones by setting five, 2-position DIP-switches. |
|
• | The sound module can work as a stand-alone audible signal when plugged into the Model LSBS Low Profile Surface Mount Base or Model LSB Pipe Mount Base. |
|
• | The Model LSS can be combined with any Litestak light module configuration of up to four colors. |
|
• | Controlling the sound module is done via the wires normally used for the clear light module. |
|
• | The sound module always occupies the top module position in a Litestak tower. |
|
• | Ideal applications for the LSS include environments where the ambient noise is not extreme - assembly lines, conveyor systems, automated lines, instrument panels and workshops. |
|
• | LSS is UL Listed and CSA Certified. |
|
• | Federal Signal′s Litestak Sound Module allows the user to add a distinctive audible signal to a Litestak Status Indicator. |
|
|

Technical Information |
|
NEMA Type 1 Enclosures constructed for |
• | indoor use to provide a degree of protection to personnel against access to hazardous parts and |
|
• | to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt). |
|
|
Comparison Between NEMA Enclosure Type Numbers and IEC Enclosure Classification Designations |
• | IEC Publication 60529 Classification of Degrees of Protection Provided by Enclosures provides a system for specifying the enclosures of electrical equipment on the basis of the degree of protection provided by the enclosure. |
|
• | IEC 60529 does not specify degrees of protection against mechanical damage of equipment, risk of explosions, or conditions such as moisture (produced for example by condensation), corrosive vapors, fungus, or vermin. |
|
• | The NEMA Standard for Enclosures for Electrical Equipment does test for environmental conditions such as corrosion, rust, icing, oil, and coolants. |
|
For this reason, and because the test and evaluations for other characteristics are not identical, the IEC Enclosure Classification Designations cannot be exactly equated with the enclosure Type numbers in this Standard. |
