The wooden buildings are provided with Hub control panels, FireProtect fire detectors, and Button smart buttons. They were installed inside the apartments/housing units. With the Ajax mobile app, the residents are immediately notified of smoke or rapid temperature rise in the premises.
Preventing false alarms
Each Ajax fire detector is an independent device with a built-in loud siren of 85 dB. Even if the Internet connection in the building is lost, all detectors will be triggered in case of danger as a unified system. This is possible due to the Interconnected Fire Alarm feature.
Special for the Bergen project, the Ajax R&D team implemented the delay of Interconnected Alarm. This minimizes false calls of the fire department.
«The development we have done with Ajax is crucial, and making the system perfect for these kinds of projects»Kristian Kleven, product and quality manager, Elotec
For example, if a person burnt food on the stovetop, they can press Button within 5 minutes (set in the app from 0 to 5 minutes) from the moment the smoke was detected. This will postpone the Interconnected Fire Alarm transmission. Then a person has another 10 minutes to handle the reason for the false alarm (for instance, to air the room). Thus, the fire department will not receive a false alarm.
However, if Button is not pressed within 5 minutes (depending on the settings), the Interconnected Alarm will be activated and the alarm transmitted to the fire department.
1 900 people now have wireless systems installed. All are monitored by the Bergen fire department
Any resident or business owner in the protected area had the opportunity to apply for the system installation. Each system is connected to the fire monitoring station for free.
Some people hesitated because of the cost if the fire brigade arrives at false alarms. With Ajax Button, and the delay of Interconnected Alarm, those worries were gone.
can also notify an alarm monitoring company about the intrusion, gas leak, or fire. Moreover, it can request medical help. In panic mode, the device supports 4 types of alarms.
Professional installer used approx 30 minutes in each apartment/housing unit
Ajax wireless equipment is ready to operate straight out of the box. Smooth installation and user experience encouraged people to add more Ajax devices to the system, at their own expense. Now wooden buildings in Bergen are also protected from burglars and floods.
This project is still going, and more Bergen districts are now joining it. There are similar projects going on in other places in Norway. In Levanger, the municipality also implemented 450 fire alarm systems monitored by the fire departments.
