What is Deaf Alerter?

Deaf Alerter® is a system that provides emergency messages about fire alarms for Deaf and hard of hearing people. This industry leading, radio-based system is installed in thousands of buildings across the UK.

Deaf Alerter helps eliminate potential risks using our unique roaming system, that allows users to receive emergency messages and communications in any building displaying the Deaf Alerter symbol.

Benefits of using Deaf Alerter – our fire alarm system for Deaf and Hard of Hearing people

Frequently asked questions:

Does Deaf Alerter aid compliance?
Deaf Alerter complies with British and European Standards, BS5839 and EN54. As well as aiding compliance with the Equality Act 2010 (formerly the DDA), making your building accessible for all.
Can I use a buddy system or flashing lights?

The buddy system can only ever be as reliable as the buddy – the buddy needs to be entirely present at the time of the emergency. While this methods have been favoured over the years, it is important to consider the limitations of these approaches and the impact this may have in emergency situations.

Is a digital messaging system safe to use?

It can be extremely dangerous to install a digital messaging system, like text messaging when it comes to fire safety for Deaf and Hard of Hearing people.

Mass notification systems, like mobile phone text messaging services, do not and cannot with current technology, meet the British and European safety standards. Weak vibrations, inconsistent signal and a poor battery life make the systems unreliable and run the risk of significant danger.

Is the system suitable for multiple buildings?
Yes, Deaf Alerter is ideal for organisations with multiple buildings. The radio-based nature of Deaf Alerter means that users can move between buildings on a site and always be covered.

Can this be used for any other purpose?
