Hybrid Lockdown Alarm Systems
Wireless and internet signalling for multi-building and multi-site estates
Hybrid lockdown alarm systems combine local wireless alerting with network or internet signalling so separate buildings or sites can share compatible activation and warning functions. This can be useful where roads, yards, remote blocks or large estates make a single wired system difficult or expensive to install.
How does a hybrid lockdown alarm system work?
A hybrid design uses more than one communication path. Local wireless devices can activate sounders, beacons or other compatible alerts within a site, while network or internet signalling can pass an approved alert between separate buildings or locations where the system has been configured to do so.
The useful part is resilience and flexibility rather than technology for its own sake. A school, healthcare estate or multi-building organisation can choose activation and warning methods that suit the site, then add compatible digital or remote functions where they are genuinely useful.
Hybrid does not mean every alert must depend on the internet. The design should define what continues to work locally if a network service is unavailable and how the system will be tested.
How people can activate and receive the alert
Multiple activation methods
Depending on the design, alerts can be raised using fixed push buttons, lanyard-style triggers or approved desktop software. The right mix depends on where staff are likely to recognise an incident.
PC and display alerts
Compatible PCs and digital signage can display a clear alert where configured. Visual messaging can supplement sound in busy or noisy areas, but coverage still needs to be checked site by site.
Sound, beacons and voice
Compatible sounders, flashing beacons and recorded voice messages can be combined where appropriate. Voice content can be configured for the site's chosen wording and language requirements.
Mobile notifications
Optional notifications can be sent to approved staff mobile devices where the chosen platform and site policy support this. Mobile alerts should supplement, not replace, reliable on-site warning methods.
UK-wide lockdown alarm installation and support
Camelott® supplies and supports lockdown alarm systems across England, Wales, Scotland and Northern Ireland. For multi-site estates, we can review whether one common alerting approach can be used across different buildings while allowing for local site layouts, radio coverage and network availability.
England
Schools, healthcare, workplaces and multi-building estates across England.
Wales
Coverage across all Welsh local authority areas, including rural and multi-site locations.
Scotland
Site-specific design for education, healthcare and other organisations across Scotland.
Northern Ireland
Remote assessment and project planning for suitable multi-building and multi-site requirements.
Hybrid lockdown alarm FAQs
What is a hybrid lockdown alarm system?
A hybrid lockdown alarm system combines more than one signalling method, such as local wireless devices with network or internet communication between compatible buildings or sites.
Does a hybrid system stop working if the internet fails?
It should not automatically be assumed that all functions depend on the internet. The design should identify which alerts continue to work locally during a network outage and which cross-site functions require a connection.
Can one lockdown alarm link separate school buildings?
It can where the proposed system, radio coverage and network design support it. Detached buildings, roads, distance and construction materials should be considered during the site survey.
Can staff activate the system in different ways?
Depending on the configuration, activation can include fixed push buttons, lanyard-style devices or approved desktop software. The locations and methods should follow the site's emergency procedure.
Does Martyn's Law require a hybrid lockdown alarm?
No. Martyn's Law does not mandate a specific alarm product. A dedicated alerting system may support lockdown and communication procedures where it is appropriate for the premises.
Need to link alerts across more than one building or site?
Tell us how your buildings are laid out, how far apart they are and how staff currently raise an emergency alert. Camelott® can review wireless, network and hybrid signalling options and identify what should continue to work locally if a connection between sites is unavailable.
Martyn's Law does not mandate a specific lockdown alarm product, and the main duties are not yet in force. A lockdown alarm should support the organisation's emergency procedure, risk assessment, training and current official guidance. Read our Martyn's Law guide .
