Tonelight Warning Indicators with Stainless Steel Housings

Tonelight annunciators emit both sound and flashing lights, which is especially desirable in environments with high levels of ambient noise.

Tonelight annunciators emit both sound and flashing lights, which is especially desirable in environmental conditions with high levels of ambient noise.

In addition to their stainless steel housings and buttons for use in harsh environments, the new Tonelight models from Transducers USA are available with green, yellow, orange, blue, white or red LED lens covers. Two new models are offered:

TRIP-LB100SS-R12 – The voltage rating for this model is 12 VDC. Other models include 24 VDC and 110 VAC to 220 VAC. The siren operates at 85dB @ 10cm. Operating temperature range is -20⁰ C to +55⁰ C. A screw terminal provides for panel mounting. This model is rated IP50 and IK04.

TRIP-LB150SS-R12 – The voltage rating for this model is 12 AC/DC. Current rating is ≤30mA. Its siren also operates at 85dB @10cm. This model is rated IP40.

All Tonelight units provide distinct audio/visual warnings with flashing LED lights and repetitive audio alerts. The sound and light alert signals can be emitted simultaneously or separately. In addition, Tonelight allows the audible alert signal to be delayed, allowing workers to have time to respond to visual alerts before the audible beeping begins.

This feature is ideally suited where excess noise is either undesirable or hard to detect. The Tonelight indicators are ideal for potentially serious events where both audio and visual warnings are needed. Typical applications for Tonelight include:

  • Alarms of all types
  • Low-voltage
  • Low-pressure
  • High-radiation
  • Tank Level
  • Cycle Status
  • Dangerous Condition
  • High-temperature
  • Liquid Detector

Transducers USA customers are finding the Tonelight warning indicators very helpful in many applications, such as:

  • On dashboards of RVs, off- and on-road highway and other vehicular equipment, providing warning when the contents of storage or collection tanks are either full or empty
  • Industrial machines and factory floor operations
  • Restaurant kitchens
  • Mobile and portable applications
