More Information
Designed to improve protective security and organisational preparedness across the UK, Martyn’s Law means that those responsible for certain premises and events need to be better prepared and protected, ready to respond in the event of a terrorist attack or security incident.
Standard tier venues (with capacities for 200-799 people) need public protection procedures, including lockdown, communication, and evacuation/invacuation plans. Enhanced tier venues (with 800+ capacities) need the same but are additionally required to implement other specific measures and monitor the premises and immediate vicinity.
C-TEC’s battery-backed and fully-monitored lockdown solutions have been designed to help schools, theatres, shopping centres and other commercial and public venues comply with the legislation.
How does a lockdown system work?
A lockdown system (sometimes known as an invacuation system) is typically used to direct people to a designated secure area within a building to avoid threats from, say, active shooters or bomb alerts. To do this they sound distinctive alarms and/or voice messages throughout the building that are different from a venue’s fire evacuation or burglar alarm tones to avoid confusion.
The exact operation of a lockdown system and the actions that need to be taken when a threat is detected will be dependent on the venue’s risk assessment and emergency plan.
As requirements will differ from site to site, C-TEC’s lockdown solutions are designed to be tailorable to a building’s specific needs.
Our LAP501/CA single-message lockdown alert panel is ideal for smaller, straightforward applications and is designed to broadcast a full lockdown alert voice message when a lockdown call point is activated to indicate there is an immediate threat within a building.
For larger, more complex applications we also have a range of multi-message lockdown solutions available via our dedicated LAP2/CA mult-message lockdown-alert panel or any ZFP CAST-protocol addressable fire panel.
Custom or coded voice messages can also be arranged by special order – contact our lockdown system support team at lockdown@c-tec.co.uk for more details.
