By Syed Muhammad Daud Rizvi — Co-founder of TapOkie Work. Building lone worker visit check-ins and audit-ready monitoring for small teams — without enterprise lock-in.
Man-down alarms detect falls automatically via wearable hardware and typically connect to an Alarm Receiving Centre (ARC). Timed check-in sessions require the worker to actively start and end a visit, with missed check-outs triggering manager alerts. For most SMB field, home-care, and charity roles, a reliable timed session app with an SOS button provides proportionate protection without the cost and false-alarm burden of wearable fall sensors.
The Question Most Managers Are Getting Wrong
Search for "lone worker protection" and you will quickly land on pages promoting man-down alarms, body-worn cameras, and Alarm Receiving Centres. The marketing is compelling. The imagery — a worker collapsed alone in a warehouse — is designed to make you feel that anything less than wearable fall-detection is negligent.
It might not be. In fact, for a significant proportion of lone workers in the UK, spending money on man-down hardware is the *wrong* decision — not because safety doesn't matter, but because it does not match the actual risk.
This guide explains honestly what each approach does, where each works best, and how to let your risk assessment — not a vendor's brochure — drive the choice.
What a Man-Down Alarm Actually Does
A man-down (or fall-detection) alarm is a piece of wearable hardware, usually a clip, lanyard fob, or body-worn device, fitted with accelerometers and sometimes GPS. The device monitors motion continuously. When it detects a rapid deceleration (a fall), prolonged horizontal position (lying motionless), or no movement over a set period (lack of motion/no-movement alarm), it automatically triggers an alert.
That alert typically goes to an Alarm Receiving Centre (ARC) — a staffed facility operating 24/7 that will attempt voice contact with the worker, contact a manager, and in some cases request emergency services.
What man-down does well
- Detects incapacitation without any action from the worker (critical if they are unconscious)
- Provides continuous, hardware-based monitoring with no dependence on the worker remembering to start a session
- ARC escalation means a professional operator handles the response, not a line manager who may be in a meeting
What man-down does less well
- False alarms are common. Motion sensors cannot reliably distinguish a worker bending over to pick something up, sitting down hard, or placing the device on a surface from a genuine fall. In high-movement roles (domiciliary carers helping clients out of chairs, estate agents walking building sites) false alarm rates can be significant. Every false alarm costs time, erodes trust with the ARC, and — importantly — can make workers switch off or mute the device altogether, which defeats the purpose entirely. See our related post on lone worker false alarms and session warnings.
- Cost and complexity. Wearable hardware means procurement, charging discipline, replacement of lost or damaged units, and ongoing ARC subscription costs. For small charities, care providers with twenty staff, or estate agencies with a handful of negotiators, this is a real operational burden.
- Not always suitable. Workers in customer-facing roles — visiting clients in their homes, showing properties, conducting field surveys — may find wearable devices impractical, intrusive, or inappropriate for the professional impression they need to make.
What a Timed Session Check-In Does
A timed session approach — like the Start Visit / End Visit workflow in TapOkie Work — places the control in the worker's hands and the safety net in the timer.
The worker opens the app, taps Start Visit, and sets or accepts a session duration appropriate to the appointment. When they leave safely, they tap End Visit. If that end-visit action does not happen before the timer expires, the platform automatically:
- Sends an alert to the nominated manager (email and push notification)
- Escalates to a secondary contact if the manager does not acknowledge within a set window
- Creates a timestamped log entry for audit purposes
An SOS button is available at any point during the session, giving the worker a manual emergency trigger if they feel unsafe — before any timer has expired.
What timed sessions do well
- Low false-alarm burden. Alerts are triggered by human inaction (not doing the end-visit), not by a sensor misreading movement. This dramatically reduces nuisance alerts.
- Audit trail. Every session — start time, location, end time, any alerts raised — is logged and exportable. This supports both health and safety compliance reviews and, in unfortunate events, incident investigation.
- No hardware dependency. Workers use a phone they already carry. No devices to charge, lose, or forget on a desk.
- Manager-led response. Alerts go to a real person who knows the worker, the context, and can make a sensible decision about whether to call, visit, or escalate — rather than a remote call centre operative working from a script.
- Proportionate cost. A phone-based session app is a fraction of the cost of hardware plus ARC subscription.
What timed sessions cannot do
Be honest here: a timed session cannot protect a worker who is suddenly and silently incapacitated *during* a session with no opportunity to press SOS. If a worker suffers a cardiac event or is violently assaulted without warning and cannot interact with their phone, the timer will eventually expire and raise an alert — but there is a delay. For roles where that scenario is a credible, assessed risk, additional controls are warranted.
Letting the Risk Assessment Drive the Decision
The legal obligation under the Management of Health and Safety at Work Regulations 1999 is to carry out a suitable and sufficient risk assessment and implement *proportionate* controls. The key word is proportionate. Over-engineering protection for low-risk roles wastes resource. Under-engineering for high-risk roles is dangerous.
A simple framework:
| Risk Factor | Points Towards Man-Down | Points Towards Timed Sessions |
|---|---|---|
| Worker may be unconscious/incapacitated with no warning | ✓ | |
| Work involves physical exertion in isolated locations | ✓ | |
| Worker has medical conditions affecting consciousness | ✓ | |
| Role is customer-facing, professional setting | ✓ | |
| Risk is primarily from aggressive individuals (conscious threat) | ✓ (SOS) | |
| Small team, manager available to respond | ✓ | |
| Frequent short visits (domiciliary care, estate agency) | ✓ | |
| Budget constraints, no ARC relationship | ✓ |
For most home-care workers visiting clients, the scenario managers fear most is an altercation, a client behaving unpredictably, or a worker running late and not returning. Timed sessions and SOS cover these directly. For night-security in remote industrial sites or utility engineers working in confined spaces, the incapacitation risk is real and man-down hardware earns its cost.
There is no shame in choosing the simpler solution when the risk profile supports it. In fact, choosing an unnecessarily complex solution that generates false alarms and gets switched off by workers is arguably *worse* protection than a simple system that is actually used.

A Note on BS 8484
You may have seen lone worker providers advertising BS 8484 certification. BS 8484 is the British Standard that governs lone worker device services and permits providers to request an immediate police response (a "URN" — Unique Reference Number). It is a legitimate and valuable standard in the right context.
However, it is not a legal requirement. It is a commercial certification that makes sense primarily for services that involve ARC monitoring and potential police dispatch. A manager-led, phone-based session app sits outside the BS 8484 framework — not because it is inferior, but because it is a different type of product serving a different set of risks. For a full breakdown, see What is BS 8484?.
Where TapOkie Work Fits
TapOkie Work is designed for managers who need a reliable, lightweight safety net for field and visiting roles — without the overhead of wearable hardware, ARC subscriptions, or complex device management.
It suits organisations where:
- Workers carry out planned visits to homes, offices, or sites
- The primary risk profile is time overrun, verbal aggression, or a worker failing to return rather than sudden physical incapacitation
- Managers want an exportable audit trail for compliance reviews
- Teams are small enough that manager-led response is practical and personal
It is not the right product for every lone worker situation. If your risk assessment points clearly towards incapacitation risk in environments without reliable phone coverage, you should look at dedicated man-down hardware alongside or instead of a session app.
What TapOkie Work will not do is pretend otherwise.
Summary
- Man-down alarms use hardware sensors to detect falls automatically and typically escalate to an ARC. Best for roles with genuine incapacitation risk in isolated environments.
- Timed session check-ins with SOS require worker action but generate an audit trail, eliminate most false alarms, work on existing smartphones, and produce manager alerts on missed check-outs. Best for visiting roles, home care, estate agency, field staff, and charity outreach.
- Your risk assessment should determine which approach — or combination — is proportionate for each role in your organisation.
- Cost and complexity matter. A system that workers find intrusive or unreliable and routinely bypass offers less real protection than a simpler system that is genuinely adopted.

Common questions
What is a man-down alarm?
A man-down (or fall-detection) alarm is a wearable device — typically a clip, lanyard fob, or body-worn camera — fitted with an accelerometer and/or tilt sensor. When it detects a sudden impact, prolonged horizontal position, or lack of movement, it raises an automated alert, usually to an Alarm Receiving Centre (ARC) staffed around the clock. The worker may or may not be conscious to confirm or cancel the alarm.
What is a timed lone worker check-in session?
A timed check-in session (sometimes called a visit session or timed welfare check) requires the worker to tap 'Start Visit' when they arrive at a location and 'End Visit' when they leave. If the session timer expires without an end-visit action, the system automatically alerts a nominated manager or escalation contact by email and push notification. An SOS button provides an instant manual emergency trigger at any point during the session.
Do I need an ARC for lone worker compliance?
Not necessarily. An ARC is a requirement under BS 8484 (the British Standard for lone worker services). However, BS 8484 is a commercial certification standard, not a legal obligation. The Health and Safety at Work Act 1974 and the Management of Health and Safety at Work Regulations 1999 require you to make a suitable risk assessment and put proportionate controls in place. For many roles, manager-led monitoring with documented alerts and an audit trail satisfies that duty without ARC involvement.
When should I choose man-down hardware over a check-in app?
If your risk assessment identifies a credible risk of sudden incapacitation — for example, workers in confined spaces, electrical environments, lone night-security, or roles with high physical exertion in remote locations with no phone signal — fall-detection hardware with ARC backup is worth the cost and complexity. For the majority of SMB roles (domiciliary carers, estate agents, housing officers, field sales, charity outreach) timed sessions and SOS better match the actual risk profile.
