Product Features

With a maximum sound output of 100 decibels, the Nittan EV-HIOP-SDR High Output Sounder is incredibly loud meaning there’s no reason for people to not hear it when it goes off. That way, you can ensure a quick evacuation when a potential threat has been detected.

Fully adjustable, you can select a volume between 90 and 100 dBs, whilst also having 32 tones to select from. With three tones suitable for fire alarm systems, the others are available for use with auxiliary products. Wall mountable, it’s suitable for indoors or outdoors.

IP 65 rated, the sounder is available with or without the –ve isolator. These will disconnect the part of the loop where the fault is detected to prevent damage, and once rectified, it self-resets when the issue is resolved. Please note that different styles of isolator cannot be mixed on a system.

The low profile beacon and range of detectors fit Nittan and Nittan protocol systems and is addressed using a handheld programming tool.

For the –ve short circuit isolator version, please select the option from the drop-down menu on the right.

Don’t forget you may need to include Nittan Beacons within your fire alarm system.
