Remote Monitoring for Smoke Control: What It Can't Replace

Connected smoke control panels have changed what a building manager can see. A fault that used to sit unnoticed until the next engineer visit now lands as a notification the same afternoon, and a compliance team with forty blocks can look at all of them from one screen. That is a real gain, and it raises an obvious commercial question: does it buy back any of the maintenance visits?

The short answer is that remote monitoring replaces some of the work and none of the responsibility. This article separates the two: what monitoring genuinely does, what it cannot touch, where it pays for itself, and the questions worth asking before you sign anything.

What Remote Monitoring Actually Does

Strip away the marketing and connected smoke control offers five capabilities. Not every system offers all five, and the difference between them matters at procurement.

Fault and event notification. The panel reports a change of state to a platform, which pushes it to named recipients. Detection zone activated, actuator failed to reach limit, mains lost, battery low, panel offline. The gain is time. A fault found on day one instead of week fourteen is a fault that never had the chance to sit through a real fire.

Status visibility across a portfolio. A single view of every panel on an estate, with maintenance dates against each one. This is the capability compliance teams undervalue at tender and then use daily. Knowing which three blocks out of ninety are overdue is worth more than any individual alert.

Logs and test records held off site. Every activation, every fault, every reset, timestamped and stored somewhere that survives a flooded riser cupboard or a panel swap. This is the part that speaks directly to the golden thread.

Remote functional testing, where the system supports it. Triggering the routine test from a desk rather than a van, with the result logged automatically. Read the “where the system supports it” carefully. Plenty of panels report status and cannot be driven remotely at all.

Remote activation by a competent person. The ability to operate the system outside fire mode, for example to close vents left open after a test or to run a check with someone on site. This is the capability with the sharpest edges, and the section on questions below deals with it.

As one example of how this gets packaged, the O Range panels we supply include basic Vent Net access with every system: remote access, maintenance dates and the digital thread for the asset. Full monitoring is a separate annual service and adds event notification within seconds, live site activity, all logs and tests viewable off site, remote firefighter switch activation with automatic switch-off, a monthly testing mode and a 6-month test that can be run remotely. Other manufacturers slice the same capabilities differently. The point of listing them is that “remote monitoring” on a quotation can mean anything from a status LED on a web page to a fully instrumented platform, and the words on their own tell you nothing.

What It Cannot Replace

Start with what the guidance says the physical visit is for. The Smoke Control Association’s maintenance guidance recommends 6-monthly inspection and maintenance “to identify unmonitored faults, take preventive measures and ensure the continued reliability of the system, and make the user aware of any changes to the building that affect the protection afforded by the system.”

Read that first clause again. Unmonitored faults. The purpose of the visit is defined by what the system cannot see about itself. Better monitoring shrinks that set. It does not empty it.

Work through a real 6-monthly and annual scope and the gap becomes obvious:

• Airflow measurement. The SCA guidance expects the competent maintainer to record a representative sample of flow rates for smoke dampers or doors, measured at the top, middle and bottom of the shaft, using a minimum of nine reference points across the active area of each. No panel measures this. A damper can reach its open limit switch, report a clean actuation, and still be passing the wrong volume because of a construction defect somewhere in the shaft.
• Batteries. Panel batteries are expected to be no more than three years from date of manufacture unless the datasheet says otherwise, dated and labelled, and load tested with an approved method. A panel monitors battery voltage. It does not read the date stamp or perform a capacity test.
• The physical fabric. Shaft doors and dampers inspected for correct operation and intumescent seals present, roof vents opening fully, window vents checked for height and fall protection, free area confirmed against Approved Document B, and the shaft checked for services or equipment that were never part of the smoke control installation. Weather damage, corrosion, seized hinges, perished gaskets and quietly installed cable trays are all invisible to a control panel.
• The supporting infrastructure. Automatic transfer switch service reports, LV supplies checked for appropriate protective devices and the absence of earth leakage protection on those circuits, cable installation checked against Approved Document B, BS 8519 and BS 7671, and annual cleaning certificates for smoke ducts and shafts. These are paperwork and inspection tasks, not telemetry.
• Cause and effect against the design. The annual check is a full commissioning check against the original system design. A monitoring platform can confirm that a zone did what its current configuration told it to do. It cannot tell you whether that configuration still matches the fire strategy after a corridor was subdivided or a door line moved.

Then there is the part no product replaces. Article 17 of the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to keep fire safety facilities and equipment under a suitable system of maintenance and in efficient working order. Regulation 7 of the Fire Safety (England) Regulations 2022 puts monthly routine checks of essential firefighting equipment on the responsible person in high-rise residential buildings, along with a duty to report an unrectified fault in a firefighters’ lift or evacuation lift to the fire and rescue authority when it cannot be fixed within 24 hours. In higher-risk buildings the accountable person carries golden thread duties under the Building Safety Act 2022 and the information regulations made under it.

None of those duties transfer to a supplier because a dashboard exists. Monitoring is evidence that a duty holder is discharging a duty. It is not a substitute duty holder.

Where It Genuinely Earns Its Money

Four cases, and they are not equally strong.

Multi-site portfolios. This is the strongest case by a distance. The problem a housing provider with ninety blocks has is not diagnosing one panel, it is knowing which panels need attention this week. Portfolio visibility solves a management problem that no amount of engineering skill on site can solve.

High-rise residential under Regulation 7. Monthly checks, records made available to residents, and a 24-hour clock on certain faults. A system that timestamps its own events and holds the log off site makes that regime easier to run and much easier to evidence when someone asks for two years of records.

Golden thread evidence. Records that are generated as the system runs, rather than typed up afterwards, are better records. They are contemporaneous, they are complete, and they do not depend on a folder being passed between managing agents. If the platform can push events and test results into a CAFM or asset management system through an API, the building’s own asset register stays current without anyone re-keying anything.

Routine test visits. The weekly regime is the one with real money in it. BS 9999 Annex I expects tests to be run weekly, with all zones in a smoke control system simulated at least once every three months, which the SCA translates into a rolling schedule of one zone per week for a five-storey building up to four zones per week for a twenty-storey one. A system that can run and log that remotely takes a recurring van roll out of the programme. A system that only reports status does not.

There is a fifth, quieter benefit that rarely appears on a business case. When the engineer does attend, they know what they are attending for. Arriving with the right actuator on the van instead of booking a return visit is worth more per year on a large estate than most of the alerting.

What the Guidance Actually Credits

Here is the awkward part, and the reason to be careful with any supplier who tells you monitoring reduces your obligations.

The SCA maintenance guidance sets minimum recommended intervals and describes who carries out each one: daily and weekly checks by a nominated or competent person, monthly checks aligned to Regulation 7, 3-monthly and 6-monthly checks by a competent maintainer, and the annual by a certified SDI 19 organisation. It does not contain a mechanism for reducing those intervals because a system is monitored. The intervals are the baseline whatever the panel can do.

Where monitoring can legitimately do the work is in how a check is carried out rather than whether it happens. Regulation 7 defines a routine check as one confirming the equipment is in efficient working order and in good repair, carried out in accordance with the relevant industry standard or the manufacturer’s recommendations. A remotely triggered test that exercises the same devices as a manual test, produces the same evidence of actuation and records it against a date is a reasonable candidate for part of that check. The daily status check is another obvious candidate, given the SCA task is to look at the status panel and confirm a clear indication of normal operation.

Whether that is sufficient in a specific building is a fire risk assessment question. The SCA guidance itself notes that the building representative should take the risk assessment, the complexity of the building and the systems, the users and the operation into account when constructing a maintenance schedule, and recommends more frequent inspection where risk is higher. So the honest position is: remote capability can change how some checks are performed, the decision sits with the responsible person and their assessor, and it should be written down rather than assumed. Anyone selling you a reduction in your statutory regime is selling you something they cannot deliver.

The Questions Worth Asking Before You Sign

Six, in rough order of how often they turn into problems.

Who owns the data, and what happens when the contract ends? The logs are part of the building’s safety record. Ask who holds the account, whether the building owner can export events and test records in a usable format, what happens to historic data if the subscription lapses, and whether a new maintenance contractor can be granted access without replacing hardware. A monitoring arrangement that only works while one contractor holds the keys is a lock-in dressed as a service.

What is the failure mode when connectivity drops? Two separate questions here. Does the panel still function in fire mode with no network? It must. And does the platform raise an alert when a panel stops reporting? If loss of communication looks the same as a healthy site, the monitoring is worth considerably less than the quotation suggests. Ask how quickly the platform notices, and ask the same question about mains loss.

Who can log in, and what can they do? Remote activation is a genuine capability and a genuine attack surface. Named accounts, two-factor authentication, an audit trail of who did what, and clear separation between viewing status and operating plant are the minimum. The IET Code of Practice on cyber security in the built environment, supported by the NCSC, is the reference to point a client’s IT team at. Treat a connected smoke control panel as an operational technology asset, because that is what it is.

Who acts on an alert at three in the morning? This is where most monitoring deployments quietly fail. An alert with no named recipient, no out-of-hours route and no agreed response time is a log entry, not a control measure. Write the escalation path into the maintenance contract: who is notified, by what method, what they are expected to do, and what happens if they do nothing.

What does the alert actually mean? Ask for the alert taxonomy before you buy. How many distinct fault types can the system report, and how specific are they? “System fault” on a panel serving twelve zones does not tell an engineer what to bring. And ask what generates nuisance notifications, because a platform that cries wolf every time someone tests a call point will be muted within a month, which is worse than no monitoring at all.

What does a green screen prove? Less than it feels like it proves. A dashboard reports the state of the inputs the system has. It does not report a blocked free area, a cleaner’s cupboard built into a lobby, an actuator opening to the wrong angle, or a cause and effect that no longer matches the fire strategy. The most expensive risk in this whole subject is a compliance team that stops asking questions because everything is green.

Writing It Into a Maintenance Regime

Keep the SCA intervals as the baseline and record, interval by interval, what the connected system carries and what still needs a person. Something like this, adjusted to your building and agreed with your assessor:

Three habits make the difference between monitoring that helps and monitoring that creates arguments. Log remote tests in the same logbook as everything else, so the record is one record rather than two that disagree. Name the person competent to trigger remote operations and keep that list current, because “the panel can do it” is not the same as “we know who did it”. And keep the annual joint inspection with your other maintenance providers, which the SCA recommends anyway, since the interfaces between fire alarm, smoke control and other building systems are exactly where remote status views tend to be thinnest.

Practical Takeaway

Remote monitoring is a maintenance tool with a genuine, measurable return: faster fault detection, portfolio visibility, better records, and fewer van rolls for routine testing on systems that support remote actuation. It is not a compliance product. The statutory intervals stay where they are, the responsible person and the accountable person keep their duties, and the physical inspection keeps doing the job the guidance says it is there for, which is finding the faults the system cannot see in itself.

Buy it for the operational gain and the evidence quality. Specify it against the six questions above, particularly data ownership and the connectivity failure mode. Write the resulting regime down with your fire risk assessor rather than letting a supplier’s brochure define it. And treat a green dashboard as one input into a compliance judgement, never as the judgement itself.

Replacing a Panel That Tells You Nothing?

If the monitoring conversation started because a legacy panel is an anonymous box on a wall, the honest fix is usually the panel itself. We stock smoke control panels with UK stock in Poole and next-working-day despatch on most lines, and our technical team can talk through what a given system can and cannot report before you commit to a monitoring subscription alongside it.
