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.

Features & Benefits

• Tones are compatible with Askari, Squashni and Flashni sounders
• Automatic synchronisation
• Roshni sounders fit all Fulleon bayonet bases
• They are suitable for use within general signalling or as a process plant alarm
• The sounder has a high sound output
• Low current consumption
• 32 tones for the user to select
• Volume control
• Second tone for two-stage alarms
• Lockable base (on certain Roshni products) - 529-4430, 530-5861
• Suitable for indoor and outdoor use

Where a range of values are specified for sound output levels and current consumption, the actual figures will depend on the tone chosen, and the volume setting where adjustable.
