Healthcare estate monitoring for vaccine fridges, plant rooms, water temperatures and room pressure, reported to the estates dashboard, which alerts with escalation and keeps the record estates governance needs.
We build the complete system ourselves: the sensors, the ZARC Gateway, and the dashboard your estates team works from. The gateway connects over 4G or Wi-Fi, and on 4G it stays off the hospital network, so fitting it needs no IT project and nothing touches clinical equipment. Once it is in, sensors for any further need can be added at any time.
Estates, not clinical systems
Medicine, vaccine and specimen storage, with alerts and a full temperature history.
Flow and return temperatures reported continuously alongside the water safety records.
Differential pressure across isolation rooms and filter banks, with alerts on range.
Boiler and chiller faults, mains supply to critical rooms and water on the floor.
Fridges, boilers, water systems and ventilation report continuously to one dashboard covering every site, and the same gateway takes new sensors whenever the estate needs them. Each reading, alert and acknowledgement is kept with its date and time, ready for an audit or an estates governance review.
Medicine and vaccine fridges are the clearest example. A fridge that drifts warm overnight can mean stock written off in the morning. A temperature tag in each fridge reports continuously, alerts on a limit, and keeps the history that audits ask for.
Water safety depends on temperatures that are measured by hand at intervals. Tags on flow and return pipework report hot and cold water temperatures continuously, so a calorifier that drops or a cold supply that warms is seen the same day, alongside the records the water safety plan already keeps.
Rooms that rely on pressure are another. Differential pressure across an isolation room door or a filter bank shows whether the ventilation is doing its job, and an alert goes out when it falls outside the range the estates team sets.
Plant rooms, kitchens and stores hold the rest: boiler lockouts, chiller faults, mains power to critical rooms, and water on the floor. Each is read by a tag, either directly or from the equipment's own alarm output, and reported in real time.
Nothing joins the clinical network. Tags are battery-powered and transmit over 433 MHz to a ZARC Gateway with its own 4G link and battery backup. Every tag checks in on a schedule, so one that goes quiet raises its own alert.
This is estates monitoring on a best-endeavours basis. It supports the people responsible for the buildings and does not replace clinical alarms, nurse call, fire alarm signalling or any statutory system.
Cold storage
Each fridge and freezer reports temperature at an interval you set, with high and low limits and a door left open shown as a rise. Pharmacy and estates are alerted while stock can still be moved.
Water safety
Tags on flow and return pipework and at sentinel outlets report temperatures continuously, supporting the records the plan already requires. They do not replace the plan or the responsible person.
Ventilation and pressure
Differential pressure across isolation room doors, lobbies and filter banks, reported continuously with alerts outside the set range.
Plant and power
Boiler lockout, chiller fault, generator running and UPS on battery are read from volt-free outputs; mains loss to a critical room is reported on loss and on restoration.
Leaks
Leak tags in plant rooms, below tanks and under sinks in stores report water arriving and again when it clears.
Records
Every reading, alert and clear is kept with its time and exports for audits, reviews and contractor records, held in the cloud or on your own servers.
Deployment approach
Most estates begin with one building and extend once the alerts have proved themselves.
We list the fridges, plant rooms and water systems that matter, place tags, set limits and alert routes, and test every alert end to end before handover. One gateway covers a site; further tags join it without new infrastructure.
List the fridges, plant, water systems and rooms that matter, and who is responsible for each.
Room by room
Confirm tag positions, gateway placement and 433 MHz coverage through the building fabric.
Coverage
Set temperature and pressure limits, reporting intervals and alert routes in and out of hours.
Limits and routes
Test every input and confirm each alert reaches every recipient before handover.
Tested end to end
Add buildings onto the same dashboard, grouped the way the estate is run.

FAQ
Medicine, vaccine and specimen fridges and freezers, plant room temperature and faults, hot and cold water temperatures for water safety records, differential pressure across isolation rooms and filters, mains power to critical rooms, and water leaks.
No. It is an estates monitoring layer that supports the people responsible for the buildings. It does not replace clinical equipment alarms, nurse call, fire alarm signalling or any statutory system.
Yes. Every fridge and freezer reports at an interval you set, with alerts on limits and a full temperature history that exports for audits and reviews.
No. The tags transmit over 433 MHz to a ZARC Gateway with its own 4G link and battery backup, so nothing joins the clinical or corporate network.
Whoever you name for each building or room: estates, pharmacy, facilities or the on-call engineer. Alerts are raised on the dashboard and sent by SMS, email or both, with separate routes in and out of hours and escalation to further contacts.
No. There are no per-alert, per-user or licence charges; the system is charged monthly per tag and per gateway.
