A complete school lockdown alert solution, not just standalone alarms.
Camelott® surveys the site, designs the coverage, supplies and configures the equipment, installs the system, trains authorised staff and provides ongoing monitoring and support options. Detailed procedural guidance remains on our separate school lockdown alarm system guide.
Survey-led design
Equipment quantity and location are based on the buildings, outside areas, activation points and alert coverage required by the school.
Wireless installation
Battery-powered equipment reduces the need for extensive alarm cabling, containment, ceiling access and inter-building cable routes.
Ongoing system support
Monitoring, testing, low-battery reporting, staff training and maintenance options can continue after commissioning.
What a Camelott® school lockdown alarm can include.
The system is configured around the building layout, alert coverage, authorised activation points and the school’s agreed emergency response plan.
Distinct alarm sounds
Choose from 32 alert sounds on compatible units, with adjustable volume up to 117 dBA, so the warning can be clearly different from the normal fire evacuation signal.
Sounders and blue beacons
Combine loud audible warning with high-intensity flashing blue beacons to improve recognition in noisy areas and extend the alert beyond sound alone.
Protected call points
Dedicated blue call points with protective covers provide clearly identified activation locations while helping to reduce accidental operation.
Optional voice annunciation
Pre-recorded, coded, bespoke or multilingual voice messages can provide clearer instructions than a tone alone where the response plan requires them.
Computer text alerts
Optional software can display a customised message on networked computers, silently or with an accompanying sound, to extend the warning beyond wall-mounted units.
Digital notifications
Configured notifications can alert selected staff by email and text when the alarm activates or when chosen system events require attention.
Low-battery and missing-unit warnings
Compatible units report battery condition, signal strength and missed check-ins, helping identify equipment that is offline, out of range or requires investigation.
Silent system checks
Authorised users can initiate site-wide or individual-unit checks and review reporting without repeatedly sounding the full audible alarm during lessons.
Multiple activation options
Fixed call points, authorised dual-button key fobs and selected software controls can reduce dependence on one reception desk or distant central panel.
Indoor and outdoor equipment
Weather-rated options can extend alerts to playgrounds, gardens, sports areas, workshops and other external parts of the school estate.
Core alarm does not rely on Wi-Fi
The standalone radio alarm can activate sounders and beacons independently of school Wi-Fi. Network access is used for monitoring and selected digital notifications.
Expandable across the estate
Add units, repeaters and linked bridges to cover larger campuses, separate zones, additional buildings and multi-site academy trusts as requirements change.
Wireless installation means less disruption and building work.
Battery-powered wireless equipment removes the need for extensive inter-building alarm cabling and gives schools more flexibility when protecting mixed or changing estates.
Rapid installation
Units can normally be mounted, programmed and tested more quickly than a site-wide hard-wired system requiring long cable routes.
Lower installation labour
Less cabling, containment, ceiling access and making-good can reduce labour and disruption compared with extensive wired installation.
Minimal structural disturbance
Avoid unnecessary wall chasing, lifted floors and trenches between buildings. Only approved mounting work is required at each selected position.
Flexible site coverage
Protect classrooms, halls, offices, portacabins, detached blocks and outside areas without being restricted by existing cable routes.
A site-wide system designed around the school.
The required quantity and position of call points, sounders, beacons and repeaters should follow the site layout and coverage requirement—not an arbitrary package size.

Site and coverage review
System specified to requirement
Configured and commissioned
Training, testing and maintenance
From site survey to commissioned lockdown alarm.
The process establishes coverage, configuration and staff requirements before equipment quantities are finalised.
Requirement review
Discuss the site, existing procedures, buildings, outside areas and desired alert methods.
Site survey
Assess radio paths, sound coverage, visual warning needs, mounting constraints and difficult construction materials.
System design and quote
Specify equipment, locations, monitoring options, training and an itemised project quotation.
Installation and commissioning
Fit, label, programme, test and document the system with minimal disruption to the school.
Training and support
Demonstrate activation, reset, testing and reporting, then provide the agreed maintenance and support arrangements.

A clear alarm supports the emergency plan.
Current education guidance emphasises suitable, proportionate security plans, realistic risk assessment, staff understanding and a way to raise an alarm during an incident. The alarm supports those arrangements; it does not replace the school’s procedures, training or risk assessment.
Quick to activate
The warning method should be capable of being raised promptly when a serious incident is identified.
Reach the necessary people
The alert should reach teaching and non-teaching staff and the other people included in the site plan.
Distinct from the fire signal
The lockdown warning should be clearly distinguishable from the normal fire evacuation signal so the response is not confused.
Supported by procedure and training
The alarm forms part of the school’s wider risk assessment, written plan, staff training, testing and communication arrangements.

Martyn’s Law: the Terrorism (Protection of Premises) Act 2025 has received Royal Assent. Current SIA guidance says the Act is expected to come into force in spring 2027. A lockdown alarm should not be presented as automatic Martyn’s Law, Ofsted or statutory compliance; suitability depends on the organisation’s risk assessment, plans, procedures, training and testing.

School lockdown alarm system questions answered.
Commercial and technical questions commonly asked during school lockdown alarm enquiries.
What is included in a Camelott® school lockdown alarm system?
The final design can include wireless sounders, flashing beacons, protected call points, voice annunciators, portable activation devices, desktop alerts, email and SMS notifications, an IP bridge, system-health monitoring, silent testing, outdoor units, installation, configuration, training and ongoing support.
Should a school lockdown alarm sound different from the fire alarm?
Yes. The warning should be clearly distinguishable from the normal fire signal so staff do not interpret the alert as routine evacuation. The chosen sound or message also needs to be supported by the school’s written procedure and staff training.
How far can the wireless system reach?
Alertex equipment is specified with a maximum range of up to 1 km line of sight. Actual performance through buildings depends on construction, terrain, interference and unit position, so Camelott® surveys and tests the intended coverage.
Can the system cover portacabins, playgrounds and sports fields?
Yes, subject to survey and equipment selection. Wireless units, repeaters and weather-rated options can extend alerts to detached classrooms, temporary buildings, outdoor play areas and sports facilities without running alarm cables between every building.
Will the alarm still work if school Wi-Fi or internet access fails?
The core radio alarm can operate independently of school Wi-Fi to activate sounder and beacon units. Network connectivity is required for bridge functions such as remote monitoring, desktop messages and selected email or SMS notifications.
Can the system send desktop, email and SMS text alerts?
Yes, where the optional bridge and related services are configured. Desktop software can display customised messages on networked computers, while selected staff can receive email and SMS notifications for activations and configured system events.
How does the system identify low batteries or a missing unit?
Compatible units report battery and signal information to the management system. Low-battery reports and missed check-ins can identify equipment that is offline, out of range or requires investigation.
Can the alarm be tested without disrupting lessons?
Authorised users can carry out silent visual checks and initiate site-wide or individual-unit tests through the management portal. Schools should also maintain an appropriate programme for testing the procedure and staff response.
Is wireless installation faster and less disruptive?
Usually. Battery-powered wireless equipment avoids extensive alarm cabling, wall chasing, lifted floors and inter-building trenches. The work still requires an approved design, suitable mounting positions and commissioning tests.
Does wireless installation help minimise asbestos disturbance?
The wireless approach avoids extensive cable routes, ceiling access and disruptive internal building work. Where drilling is required, Camelott® only drills into brickwork and this is normally carried out externally. Internally, no drilling is normally required as part of the installation, helping minimise disturbance to the building fabric.
How much does a school lockdown alarm cost?
Cost depends on the number and type of buildings, activation points, sound and visual coverage, outdoor areas, voice units, monitoring, digital notifications and support requirements. Camelott® provides a site-specific design and quotation rather than relying on a generic package.
Can the system be expanded later?
Yes. Additional sounders, beacons, call points, repeaters and linked bridges can be added where the school opens new buildings, changes the layout or requires additional zones and alert methods.
What happens after installation?
Camelott® commissions the system, demonstrates activation and reset, provides agreed handover information and trains authorised users on testing and reporting. Ongoing support and maintenance options can then be arranged.
