Lone worker alarm monitoring

What is a lone worker alarm?

A lone worker alarm is a personal device — a fob, app or badge — that an employee working alone can use to raise an alert, which goes to a monitoring centre that can listen, locate and escalate to the police. Where the service is provided and monitored to BS 8484, it can access a police response level normally reserved for confirmed alarm activations.

Devices vary: a discreet button, a badge that also detects a fall or a period of no movement, or an app on the worker's phone. Most combine a manual alert with automatic triggers, since a worker who has been knocked unconscious cannot press anything.

On activation the centre typically opens an audio channel to assess what is happening, uses location data, and escalates according to a plan — to a manager, or to the police.

The BS 8484 point is what makes it more than a phone call: compliance is what gives the monitoring centre its police escalation route.

It is commonly used by lettings and estate agents, housing and care staff, engineers and drivers, healthcare visitors, and retail staff handling cash or closing alone. For employers it forms part of demonstrating that lone working risk has actually been managed rather than noted.

What is BS 8484?

BS 8484 is the British standard for lone worker services and devices, covering how a personal safety alarm is provided, monitored and escalated to police. A lone worker system monitored to BS 8484 by a certificated centre can obtain a police response level normally reserved for confirmed alarm activations.

It exists because a lone worker alarm is a different problem from a building alarm: there is no fixed address, the user is the sensor, and the response needs to reach a person who may be moving.

The standard covers the device, the service around it, how the user is trained, how the monitoring centre verifies an activation, and how it passes the call to the police. Compliance is what makes the police escalation route available.

It is relevant to employers with staff working alone — lettings agents, care and housing staff, engineers, retail managers doing cash runs — and is often part of demonstrating that an employer has met its duty of care.

What is different about alarm monitoring for a business?

Commercial monitoring usually involves a higher system grade, dual-path signalling, open and close reporting so the Alarm Receiving Centre knows whether the premises were set on time, and a paid response arrangement rather than personal keyholders. Insurers are also far more likely to impose specific conditions.

The operational differences matter more than the technical ones. A business has staff who set and unset the alarm, which means user error, shared codes and leavers who still know the code. Open and close reporting addresses part of this: the ARC expects the premises to be set within a window and raises an exception when they are not, which catches both a forgotten lock-up and a member of staff being held back at closing.

Response is normally contracted rather than personal. Few managers want to be the 3am keyholder, and a business needs cover during holidays and turnover.

Multi-site operations should ask about consolidated reporting — one view across sites, with per-site escalation — because managing ten separate contracts with ten separate ARCs is how sites end up unmonitored without anyone noticing.

Fire alarm monitoring, remote CCTV and lone worker cover are often added to the same contract, which is usually cheaper and always simpler than separate arrangements.
