Crystal motion monitoring tag

The ZARC crystal motion tag reports the moment something it is fitted to is lifted, moved, tilted or knocked from its position. Fit it to a fire extinguisher, a defibrillator cabinet or any piece of equipment that should stay where it is, and an alert arrives in real time when it is disturbed. It runs on its own battery and needs no wiring.

01

What it reports

A crystal sensor inside the tag responds to movement of the item the tag is fixed to. When that item is lifted, moved, tilted or knocked, the tag reports the event straight away, so the people responsible know it has been disturbed.

Sensitivity is set per tag. A heavy cabinet that should never move can alert on the smallest disturbance. An item that is often brushed past can be set to ignore a knock and report only a real lift.

Each event is timed and logged. The record shows when an item was disturbed and how often, and schedules can treat a movement during working hours differently from one at night.

02

Applications

Anything that must stay where it is, and must be there when it is needed, can report when it is disturbed. These are the uses we are asked about most, and the list is not exhaustive.

Fire extinguishers

An extinguisher taken from its bracket and not put back, or discharged and returned empty, leaves a gap nobody sees until a fire. The alert shows it was moved the day it happens. Complementary to routine checks and servicing, never a replacement.

Defibrillators and their cabinets

A defibrillator lifted from its cabinet may be in use or may have been taken. Either way, the people responsible know at once.

First aid, spill and emergency kits

Kits that are opened and never restocked are found wanting at the worst moment. Movement shows they were used and need checking.

Emergency grab bags and evacuation equipment

Equipment kept ready for one day is only useful if it is still there on that day.

Equipment that must not be moved

Instruments, cabinets and fixed equipment where a movement means tampering or an unauthorised change.

Doors, shutters and hatches without a contact

Where a magnetic contact cannot be fitted, such as a roller shutter or an irregular hatch, the movement of opening it can be reported instead. Where a contact can be fitted, the door state tag is the better choice.

High-value and display items

Items on display or in storage that should never be lifted outside set hours.

03

Where it can go

The tag fixes directly to the item it watches, so it moves when the item moves. It is small, runs on its own battery and needs no wiring. Typical fittings:

On a bracket or stand

The extinguisher or its bracket, so a lift is reported.

Inside a cabinet

A defibrillator or first aid cabinet, reporting when the contents are disturbed.

On equipment

The housing of an instrument, cabinet or machine that must not be moved.

On a door, shutter or hatch

Where a contact cannot be fitted.

On outdoor items

Barriers, signs and site equipment, in an enclosure specified for the location.

Across a building or an estate

Every extinguisher and defibrillator on one dashboard.

04

In the dashboard

Every item shows its live state and a full history of each time it was disturbed, with the time and how often. The dashboard works out which items are disturbed most, which have been moved and not settled again, and which moved outside their permitted hours, per building or across an estate. Records export for safety records, audits and insurers.

Alerts are pushed in real time on any movement, or only on movements outside the hours you set. They go by email or SMS, and through an app where required, to the people you name, with escalation to further contacts.

  • Live state of every monitored item, grouped by site
  • Every disturbance logged with its time
  • Items disturbed most often
  • Movements outside permitted hours
  • Sensitivity set per item
  • Site-by-site comparison across an estate
  • Full event history, exportable
  • A tag that misses its check-in is flagged

05

Industries

Wherever safety equipment and valuable items must stay in place and ready, including:

Healthcare

Defibrillators, emergency kits and equipment that must be where staff expect it.

Transport

Extinguishers and emergency equipment at stations and depots.

07

From requirement to live alerts

Requirement

You tell us which items matter, when they may be moved and who needs to know.

Configuration

We set the sensitivity, schedules and alert routes for each item.

Fitting

Each tag is fixed to its item, bracket or cabinet.

Commissioning

We lift or move every monitored item and confirm each alert reaches every recipient before handover.

08

How it reports

When the item moves, the tag sends the event over 433 MHz radio to a ZARC gateway, which passes it to the dashboard and raises the alert. The tag only transmits; with no receiver on board, nothing can alter its settings or reach it over the air.

Door state

Doors, gates and hatches where a contact can be fitted.

PIR motion

A person moving in a room, where this tag reports an item being moved.

Questions we answer most.

What does it detect?

The item it is fixed to being lifted, moved, tilted or knocked from its position.

Does it say where the item went?

No. It reports that the item was disturbed, and when.

Will a knock set it off?

Only if you want it to. Sensitivity is set per tag, from any disturbance to a deliberate lift only.

Can it tell working hours from night-time?

Yes. Schedules set when movement is expected. Movements inside those hours can be logged quietly, and movements outside them alert at once.

Does it replace extinguisher or defibrillator checks?

No. It adds real-time visibility between checks. Routine checks, servicing and inspection regimes stay as they are.

How is it fitted?

Directly to the item, its bracket or its cabinet, so it moves when the item moves.

How fast are alerts?

Events are sent as they happen and typically reach the dashboard within a second.

Does it need mains power or wiring?

No. It runs on an internal battery for up to five years, depending on use and the check-in interval.

Can one dashboard cover every extinguisher on a site?

Yes. Every item on every site reports to the same dashboard, each with its own sensitivity and schedule.

Do alerts or extra users cost more?

No. There are no per-alert, per-user or licence charges.

Looking for something else?

We work with any sensor for any application.

Most sensing needs are met by a tag we already build, configured for your equipment. If yours needs a sensor or interface we don't list, we have the engineering to build it. Tell us what you need to measure, and we will tell you how we would do it.
