Warning Indicators Blare And Glare

Supposedly unique, the Tonelight Series warning indicators offer what the company is calling a revolutionary feature, that being the combination of audible and LED warning signals.  Tonelight annunciators emit both sound and flashing lights, which, obviously, is desirable in environmental conditions with high levels of ambient noise. 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 users to have time to respond to visual alerts before the audible beeping begins. Typical alarm types include low-voltage, low-pressure, high-radiation, tank level, cycle status, dangerous conditions, high-temperature, and liquid detection


Several Tonelight models are available with either plastic housings or stainless steel housings for use in harsh environments.  These models are sealed and IP50 rated.  Beepers emit sound levels in excess of 80 dB.  Lens color options include red, green, yellow, orange, blue, and white.  These warning indicators utilize standard 22-mm panel mounting.   The voltage operation for the series spans ac and dc: 6V, 12V, 24V, 48V, and 110V.  Another Tonelight model features a light and siren annunciator combination.  Its standard lens color is red, and the siren operates at 110dB+3dB.
