Fulleon - Roshni Sounder

Although the Roshni range of sounders are considered to be the market leaders for fire alarms, they are also used in a multitude of wider applications within an industrial and commercial environment such as intruder and industrial signalling. Roshni process sounders operate from either a low voltage AC or a DC supply without modification. The wide range of tones that are available to a user enable the sounder to be flexible and supremely adaptable - even when it's in its most basic form. The Roshni sounder from Fulleon has been created and designed for reliability whilst in operation offering high specs, rugged low-profile casing and encapsulated electronics.

• Automatic synchronisation
