A history that's deeply rooted in early communications technology

With over 2 million Roshni Low Profile (RoLP) sounders sold in the last 5 years alone, its dependability is apparent, but how did this conventional fire alarm sounder come to be? The brainchild of Fulleon, the RoLP was invented in 1980 by cleverly incorporating the technology used in telephone transducers. Now in its fifth generation, it has been one of the key building blocks of the then Fulleon, now Eaton product portfolio.

One product platform, one alert. Synchronicity across the range.

The Roshni platform of Askari, Rolp, Flashni, CS200 and Squashni products all utilize the same legacy Fulleon 32 tone table, ensuring synchronisation of all tones in an area using a variety of sounders.

An internationally compliant sounder solution for conventional fire systems

The RoLP fire alarm sounder range has been third-party certified to meet fire regulatory requirements across Europe and throughout the Middle East, Africa and Australasia including EN54. Adapted by many countries worldwide thanks to its stringent manufacturing quality audits and battery of laboratory product tests. You can bet your life on the EN54 certified RoLP to alert when it matters most.

Loud and Clear. Alerting when a life depends on it.

From commercial premises to off-shore oil platforms, an acoustic alert is typically the primary method of alarm.

Eaton has a library of over 100 industry-standard alerting tones to ensure that your notification is heard every time. Voice alert messages are available in multiple languages for fire evacuation, security or safety.
