The Job That Almost Got Away
When the phone rang at his small security installation shop in Bursa, the installer almost said no.
The caller was a textile factory owner. His 800m² facility — steel-frame construction, concrete columns, heavy machinery running six days a week — had no security system. Break-ins were a growing concern in the industrial zone. He needed something installed fast.
But there was a catch. A previous installer had quoted three full days for a wired system. That meant cable trays running along steel beams. Drilling through concrete columns. Running conduit across production floors. The factory would have to shut down. And shutting down for three days meant lost orders, delayed shipments, and unhappy customers in Europe.
The owner’s question was simple: “Can you do it without stopping production?”
The installer thought about it. Then he remembered the Roombanker system he had tested at a colleague’s recommendation a few months earlier. The hub was small. The sensors paired in seconds. The 868 MHz signal went through walls that killed Wi-Fi.
“Give me one morning,” he said.
Why a Wired System Would Have Cost Three Days of Production
The previous installer’s quote was not unreasonable — for a wired system. In a steel-frame building of 800m² with concrete columns and production equipment generating electromagnetic noise, a traditional wired alarm installation involves:
Running cables through steel beams. Steel requires special drilling equipment and cable protection. Each beam penetration adds 20 to 30 minutes to the timeline.
Mounting sensors on concrete columns. Concrete drilling is slow and dusty. Every bracket needs anchors. In an active production environment, each column takes 30 to 45 minutes.
Routing cable trays across production floors. Overhead cable trays and underfoot conduit runs are impossible to install while machinery is operating. Safety regulations require clear walkways and isolated work zones.
Testing every zone. After all the cabling, every sensor has to be tested for continuity and position. When a cable gets nicked during installation, finding the break costs hours.
Three days was a realistic quote. But the factory could not spare three hours.
The Roombanker Solution: 12 Sensors, Zero Repeaters, One Morning
The installer arrived at 8:00 AM with a single Roombanker system kit and a ladder. No cable drums. No drills larger than what you would use to mount a picture frame. No conduit. No Ethernet drops.
The Roombanker Hub went up in the factory office — a compact white unit that sits next to the router. No protruding antenna. No blinking LED panel. From the outside, it looks like standard network equipment.
The installer paired 12 PIR Motion Sensors in under 15 minutes. Each sensor took roughly 60 seconds to pair through the RB Link app: scan the QR code, name the zone, test the signal, mount the sensor. The app shows real-time signal strength before you commit to a mounting location — a feature that saved the installer from guessing.
The steel-frame building that the wired installer predicted would need three or four repeaters? The 868 MHz RBF Protocol carried through steel columns and concrete walls without a single range extender. In open air, the protocol is rated for 3,500 meters (2.17 miles). Through a steel-frame factory with 60cm concrete columns, it held strong across the full 800m² footprint.
“What I would have spent on repeaters and cable, I saved in time,” the installer said. “I was walking out the door before I would have finished the first cable run on a wired job.”
The Result: System Armed Before Lunch
By 12:30 PM, the system was armed and the factory owner had the RB Link app on his phone. He could see every sensor status, arm and disarm remotely, and set custom schedules for different zones of the factory.
| Comparison | Wired Quote | Roombanker Wireless |
|---|---|---|
| Installation time | 3 days (24+ hours) | 4.5 hours |
| Production downtime | Full shutdown required | Zero downtime |
| Repeaters needed | 3 to 4 estimated | 0 |
| Structural damage | Cable trays, 15+ drill points through concrete | 12 screw holes for sensor brackets |
| Device pairing time | N/A (hardwired per zone) | 15 minutes for all 12 sensors |
The factory did not stop production for a single hour. Not one machine paused. Not one order delayed.
Two weeks later, the factory owner called the installer back. He wanted the same system at his second facility — a 1,200m² warehouse on the other side of Bursa. The installer repeated the formula: arrived at 8 AM, done by lunch.
What the Installer Says
“I was skeptical when a colleague first told me about Roombanker. I had tried other wireless systems that could not get through two walls in a standard house, let alone a steel factory. But the 868 MHz signal is different. It is not the same class of radio as the Z-Wave and Wi-Fi stuff that has been giving wireless a bad reputation in security.
“Now when a customer asks if I can do it without damaging their building, I do not hesitate. I say yes.”
Frequently Asked Questions
How long does a Roombanker wireless alarm system take to install in a factory?
A typical factory installation takes 4 to 6 hours for up to 15 sensors, depending on building complexity and layout. The majority of that time is walking the building to plan sensor placement. The actual device pairing takes under 15 minutes.
Do I need repeaters for a steel-frame building?
In internal testing across 50 industrial sites in Turkey and Eastern Europe (2024-2025), the RBF Protocol maintained signal integrity through steel-frame construction up to 1,200m² without repeaters. Facilities larger than 2,000m² may benefit from an additional Hub for complete coverage.
Will the system operate reliably around running industrial equipment?
Yes. The 868 MHz frequency band is resistant to electromagnetic interference from industrial motors, welding equipment, and conveyor systems. In our field tests at active production facilities, no signal degradation was observed from operating machinery.
How many sensors can one Roombanker Hub support?
A single Roombanker Hub supports up to 128 wireless devices, including PIR motion sensors, door/window sensors, sirens, and automation controls. For most small to medium factories (up to 2,000m²), one Hub is sufficient.
Can the system be expanded after installation?
Yes. Adding sensors takes approximately 60 seconds each through the RB Link app. There is no wiring, no new cabling, and no structural work. The system can grow as the facility expands.
What happens if the factory internet connection goes down?
The system continues operating locally. Alarm events trigger the siren, and event data is stored in the Hub. When the internet connection restores, all events sync automatically to the RB Link app and Roombanker Portal.
