Lockdown Systems

A fire alarm tells everyone to leave the building. A lockdown tells everyone to stay inside, lock doors and move away from windows. Using the same sounder for both is dangerous, and using a shouted message or a WhatsApp group is not a system.

A lockdown alarm gives you a distinct, instantly recognisable signal — a different tone, a spoken message, or both — that can be triggered from several secure points and heard everywhere it needs to be, including outside.

Design starts with the scenarios your safeguarding lead is actually planning for: an intruder on site, a dangerous incident nearby, a chemical release, or a serious safeguarding event. Those determine whether lockdown needs to be site-wide or zoned by building.

The activation points matter as much as the sounders. Reception is the obvious one, but an incident at the far end of a site needs an option that does not require crossing it — so we typically provide additional points in the office, hall and sometimes outbuildings, plus a radio or app trigger where appropriate.

Systems can be standalone or integrated with an existing PA or fire alarm platform, using a separate tone and separate activation. Where we integrate, we prove by test that a lockdown activation cannot release fire alarm door holders or unlock escape doors — and that a fire activation always overrides lockdown.

Education Sector

Scenario review

Worked through with your safeguarding lead so the system matches the plan, not a catalogue.

Distinct alert

A tone or voice message that cannot be confused with the fire alarm, verified by test.

Multiple activation points

Reception, offices, halls and outbuildings, with optional radio or app triggers.

Zoned or site-wide

Whole-site activation or building-by-building zoning where that suits the plan.

External coverage

Sounders reaching playgrounds, fields and car parks so outdoor groups hear it.

Fire interface testing

Proof that fire always takes precedence and escape routes are never compromised.

Scenario and plan review

We meet the safeguarding lead and establish what the system needs to achieve.

Survey visit

2

Design and demonstration

Coverage plan, activation points and a demonstration of the proposed tone or message.

Within 5 days

3

Installation

Typically delivered in a holiday window or over a weekend to avoid disruption.

1–3 days

4

Commission and prove

Coverage tested inside and out; fire precedence proven and documented.

On completion

Drill support

We attend the first drill and adjust levels or zoning based on what you learn.

Lockdown vs fire alarm

Fire alarm
Lockdown alarm
Required action
Evacuate the building
Secure in place, move from windows
Signal
Standard fire tone or message
Distinct tone or spoken message
Doors
Held-open doors release
Doors secured, escape routes still usable
Precedence
Always overrides lockdown
Never overrides fire

Escape doors must remain openable from the inside during a lockdown — securing a building must never trap people inside it.

Your legal duty

There is no single statute mandating lockdown alarms, but schools have safeguarding duties under Keeping Children Safe in Education and employers have general duties under the Health and Safety at Work Act. Where lockdown is part of your emergency plan, the system must not compromise means of escape under the RRO 2005.

Why choose Recall

Frequently asked

Can we use our existing fire alarm for lockdown?

Only with a genuinely distinct tone or voice message on a separate activation path, and only where testing proves fire still takes precedence. Otherwise it is safer to install a separate system.

No. Escape doors remain openable from the inside. Lockdown secures against entry, not against exit.

Yes — useful on split sites or where a primary and secondary share a campus, so one building can lock down without alarming the other.

Yes. We attend the first drill and adjust coverage, volume or zoning based on how it actually went.

Does your lockdown plan have a system behind it?

We will review the plan with your safeguarding lead and specify what it needs.
