Eaton is pleased to announce the launch of the TWIN LED telephone signal with high intensity LED technology. 
Designed to provide signals and warning in particularly noisy environments, the TWIN LED emits 
clearly recognisable visual and audible signals even in extreme conditions 
Introduced as an upgrade for the current TWIN telephone signal, the TWIN LED offers improved 
performance with a higher ring volume up to 102 db(A) and greater visibility by using high power 
LED’s where Xenon strobes have traditionally been used. 
The TWIN LED has been designed to withstand the harsh environments of marine and offshore 
use with a seawater resistant, aluminium IP66 housing. Mounting dimensions are unchanged 
from previous versions, allowing customers to easily replace old units for new.

The Sounder EV 21 Voice is an electronic signaling device for use in indoor and outdoor. The device provides various warning tones and announcements  
prompts that are played when the supply voltage of 230 VAC or 24 VDC is switched on. 
Announcements are against warning tones clear because an announcement prompts to direct action while a warning tone must first be interpreted. 
All major tones plus some voice announcements are loaded onto a 4 GB micro SD memory card as a WAV file and can be assigned to a total of 8 signal levels.  
With any program announcements in WAV format can be produced and will be transfer to the EV21 Voice via USB interface. 
The programming of the input stages will be done via a specially software, located on the SD card and in the download area of our website 
Each signal input and each wavefile can be adjusted to an individual volume .
