Comply with the requirements of Martyn’s Law

If your premises can accommodate 200 or more people, it will be subject to Martyn’s Law. Also known as the Terrorism (Protection of Premises) Bill, this UK-wide measure aims to prepare larger premises for, and protect them from, potential terrorist attacks. These premises will include schools, businesses and public facilities. The requirements will vary depending on the facility’s capacity.

The Harmonys Trio is the ideal way to alert everyone in your facility to a lockdown. For example, you can use the GSM control box to remotely trigger an alert across all your Harmonys Trio devices. You can also transmit SMS messages to registered numbers to warn of the alert.

Martyn’s Law became law in 2025. The Home Office expects there to be a 24-month period before the legislation’s full implementation.
