How to Upgrade Your Building’s Air Quality and Safety Monitoring Systems Without Major Disruptions

E-cigarettes produce fine aerosol particles that standard smoke detectors don’t register. Most buildings have smoke detectors in every hallway and stairwell, but those devices won’t detect vaping because ionization and photoelectric smoke detectors are tuned to detect larger combustion particles, not the fine aerosol droplets made by e-cigarettes. Understanding this difference of science helps property teams see that their existing smoke detection systems won’t detect e-cigarette use.

Project teams can finally move forward on adding a vape detection system once they realize they don’t have to gut existing finished ceilings to run conduit, patch drywall and extend an already long punch list that can turn a six-week job into six months.

Why your smoke detectors already missed this

Don’t be fooled. A smoke alarm is designed to detect particles of a certain size and with a certain behavior signature. That’s tied to material being burned. Vape aerosol doesn’t have those same characteristics: all that’s really in there is a fine mist of PG and VG that’s introduced into the airstream without heat or flame. As a result, vape aerosol dissipates in a manner that doesn’t trigger an alarm. Even five feet away, right under a ceiling-mounted smoke detector, a student or employee could be vaping and never set off an alarm.

Because dedicated vape detectors are an entirely different equation than smoke alarms, treating them as such is an easy mistake for FM teams to make, and will inevitably result in under-scoping of projects. Vape detectors solve a different problem altogether, and are often sited in a different manner. They’re not fire alarms at all, but are more akin to IAQ monitors.

The hardwired retrofit problem nobody budgets for correctly

Why don’t more buildings have vape detection?

Most facility managers acknowledge the need for vape detection, but implementing these systems is costly and logistically complex. Traditional hardwired detection systems require licensed electricians to install and complete new wiring runs. After installation, systems must be inspected and receive proper sign-offs.

Coordination with building occupants is also required to install vape detectors and may be difficult or impossible in occupied schools, offices, and multifamily buildings. The process becomes more complicated due to other building considerations such as the ceiling type, fire-rated walls, and older asbestos-era construction that can be costly and time-consuming to drill and patch.

All of these factors turn what seems like a quick upgrade into a multi-week capital project that goes through its own approval process. Consider a building with forty restrooms, locker rooms, and stairwells. Implementing vape detection systems in all of those locations adds significant cost and coordination.

As a result, vape detection upgrades are often postponed indefinitely as they take a back seat to other priorities.

Battery-powered wireless sensors close the gap fast

If building a hard-wired detection system involves connecting the devices to power, pulling data lines through conduit and paying any permits required, this is a job that’s perfect for a wireless, battery-operated vape detector. No conduit, no permits (in most cases) and no electricians, just screw or stick your detector up with double-sided tape and you’re good to go.

Hard-wired detectors often require a significant investment of time, money and effort. Even if a capital project hasn’t yet been approved, property managers can deploy wireless vape detectors quickly and easily – they’re an easy installing solution for your company that doesn’t require touching the electrical system at all. All that’s needed is a technician with a floor plan and a drill (or a strong vacuum). Install a few detectors and they’ll be up and reporting in the same day.

With hard-wired detectors, you may need to schedule a contractor and shut down a portion of the building each time you add detectors. With wireless vape detectors, add a few more or move your detectors to a different location as denial or traffic data dictates and there’s no need to go through another round of construction.

Start with a real site assessment, not a guess

A good place to start when you’re shopping for a vape detection system is to walk through your facilities and identify any areas that may not have smoke detectors. This includes single stall bathrooms, locker rooms, storage closets and other areas where privacy concerns limit the ability to have fire detection. These areas are common places for vaping. Also talk to your staff to find other areas that may not have detectors and where vaping is suspected. Stairwells and loading docks may be another common area. Finally, talk to those who respond to your complaints about vaping. They may know which single stall bathroom is commonly flagged, for example, on a weekly basis. This kind of walk-thru with your facilities and security team may be more productive than a more formal area audit.

Make sure to check the Wi-Fi coverage in all of these areas. Battery operated detectors still need a reliable Wi-Fi signal. Commonly weak signal areas include concrete stairwells and some older or smaller bathrooms. Vape detectors usually communicate via the 2.4 GHz Wi-Fi band to optimize range and battery life. When shopping for a system, make sure your detectors will have adequate coverage throughout the facilities where you plan to deploy. A detector that’s out of range won’t communicate so it may be assumed the system is working properly until you receive a complaint weeks later with no alert or communication from the detection system.

A sensor is only useful if the alert reaches someone

The sensors are only half the equation, the other half is getting the alert to a real person who can act on it at the time it occurs.

Consider a vape detection sensor. If it just logs an event to a dashboard, it’s not much more than an accessory. However, if it sends a real time alert (email/SMS) and/or pushes a message out to whatever system your security team/duty manager uses, it might be worth something. Factor in a timestamp and location ID and you’ve got yourself something that could change behavior.

Don’t underestimate the value of location data. In a facility with forty rooms, “Vape detected in building” isn’t terribly useful, but “Vape detected in west restroom on second floor at 11:42am” gives staff on hand a chance to intervene before the person leaves the stall.

Think through the alert protocol ahead of time, like you would the sensor placement. Who gets notified? Who is expected to respond? What happens next?

If staff know what to do with that real-time data, your sensor network won’t just be noise.

Roll it out in phases, not all at once

Don’t be tempted to wrap the whole building in sensors from day one; that’s a lot of equipment and expense up front, and it can be overwhelming for staff.

Instead, take a phased approach, starting with two or three units in the areas visitors complain about most, bathrooms and stairwells are two big-ticket items. Let this first group work for a few weeks to confirm the alerts are working from end to end. Then, once staff are comfortable with the process, you can add sensors in secondary areas.

Phasing in sensors provides more immediate benefit to focus on as well as allowing more flexibility in budgeting staffing resources over several weeks rather than all at once. It also gives building teams time to fine-tune installation details like hanging height, sensor sensitivity, and Wi-Fi location before pulling the trigger on a larger order.

What the data tells you after 30 to 60 days

Over time, vaping detection systems become more valuable. In the month or two after installation, most facilities teams start seeing usage trends emerge (e.g. specific restrooms/stairwells, usage spikes in the hour after lunch or in the break between classes). That data helps security staff maximize their effectiveness by timing patrols to match usage patterns, instead of following a rote schedule that misses the boat.

For schools or offices with recently introduced no-vaping policies, usage trends revealed by the system serve as an objective measure of how effectively the policy has been communicated. Persistent trends in specific locations suggest that the message isn’t getting through to everyone, and provide feedback far beyond that based on sporadic civilian reports.

Specs that separate a good system from a maintenance headache

When it comes to selecting wireless sensors, don’t assume they’re all more or less the same. Battery requirements and replacement schedules can be the difference between a smart building and a smart building budget. If a sensor’s battery only runs six to 12 months before needing to be swapped out, that’s manageable, even in a large building with a ton of sensors. If the battery needs to be changed out monthly or more often, that could end up costing you (in labor costs) more than you bargained for.

Integration is another important thing to consider. Can the sensors send data to a building management system? Or are they going to run as a stand-alone app? Facility teams have enough stuff to deal with already, they don’t want an app for each sundry sensor, nor do they want a dashboard from each sensor.

Network security is also worth investigating. How does the unit authenticate on the wireless network? Are firmware updates automatically applied to the unit? IoT devices can be easy to overlook, but an un-patched device is a security issue waiting to happen.

Address the privacy question before anyone else raises it

Vape detectors don’t record audio or video, and they don’t identify people. They detect particles in the air caused by vaping. For these reasons, facilities managers should proactively address common misconceptions about these devices with tenants and staff. Many people incorrectly assume that vape detectors are hidden cameras or microphones. These concerns can represent resistance to facilities upgrades and cause conflict. A brief statement in places where detectors are located, indicating how the detectors work and what they do and do not detect can go a long way toward allaying unfounded fears. This requires no additional effort or financial outlay on behalf of facilities management and can help prevent new upgrades from spawning unnecessary disputes.

The air quality case is bigger than enforcement

People spend close to 90% of their time indoors, where pollutant concentrations can run two to five times higher than outdoor levels (EPA). While HVAC systems can help dilute these aerosols, they don’t eliminate them. Until they cycle out, the particles remain in the shared air.

Framing it as a disciplinary measure is one option. But repositioning vape detection in terms of improving building air quality is another. As part of the same indoor air quality mandate that governs ventilation standards in commercial buildings, facility managers who pitch vape detection this way tend to get faster budget approval because it stops being about “catching rule-breakers” and becomes about filling a gap to improve air quality.

Rather than a construction project, the rollout requires a short list of blind zones, a handful of battery powered sensors, and an alert path that gets to the right person. From there, it’s about listening to the data.
