Alarm units

We offer a wide range of alarm units for connection to detection loops or dedicated alarm outputs.


Our sounder portfolio is suitable for a wide variety of applications. The range includes the market leading RoLP sounder and the ultra low current Symphoni range, through to industrial sounders and bells.


The purpose of Visual Alarm Devices (VADs) is to compliment the audible alarm signal with a visual one. This may be required in areas where people are unable to hear the alarm signal, either due to a hearing disability or local conditions such as high noise levels or the need to wear hearing protection.

Combined sound/light

The combination of sound and light has been shown to improve awareness of an alarm by building occupants.
