RoLP (Roshni Low Profile) - Fire alarm sounder

The RoLP (Roshni Low Profile) is the market leading conventional fire alarm sounder. Its versatility and dependability make it suitable for virtually any sounder application across the globe. Found in commercial buildings and security applications alike, its robust design also makes it suitable for use in mountainous regions and coastal areas.

With independent fire approval from multiple countries, a weatherproof housing capable of achieving IP65, and multiple fixing methods, the RoLP is a suitable fire notification device for almost any installation. .

Low current, high performance, a leading specification

From chairlifts in the Alps, used as a cautionary start-up alert, to alerting people to danger in buildings worldwide, the RoLP is a signalling leader.

Reaching a current consumption as low as 30mA, this versatile sounder isn’t just efficient, it's adaptable too. With a choice of 32 tones (including 6 fire approved) and 5 base options, configuring the RoLP to your application is easy.

Whether it's for fire notification or for general signalling purposes, the RoLP fire alarm sounder has you covered.

One of the world’s most recognized sounders, the Rolp’s flexibility and dependability continue to make it the number one choice for installers and engineers.

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.

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.
