A smoke detector that only beeps does not help if you are not at home. The Ajax FireProtect 2 detects smoke, heat and carbon monoxide, sounds the alarm on site with an 85 dB siren and sends a notification to your phone straight away via your Ajax Hub. If one detector is triggered, they all sound the alarm. In this article you can read what is mandatory in the Netherlands, which FireProtect 2 variants are available and how to choose between RB, SB and AC.

Which smoke detectors are mandatory in the Netherlands?
Since 1 July 2022, a smoke detector has been mandatory on every floor of a home, including existing homes. The detector must be placed on an escape route, in practice the hall or landing, and mounted on the ceiling. A carbon monoxide detector is not legally required, but is strongly recommended in rooms with a central heating boiler, geyser, stove or fireplace: CO is odourless and invisible, which is exactly why it is dangerous. With the FireProtect 2 range you cover both risks within your Ajax system.
What do RB, SB and AC mean?
The FireProtect 2 comes in three power versions. RB (replaceable battery) runs on two replaceable CR123A batteries that last up to 7 years; after that you only replace the batteries. SB (sealed battery) has a sealed battery that lasts up to 10 years; the batteries cannot be changed, so at the end of its life you replace the detector. AC connects to mains power, useful where wiring is already in place. Detection and siren are the same in all versions; the difference lies purely in the power supply.

Tip prices come live from our webshop. Only need carbon monoxide detection, for example alongside an existing smoke detector? Then there is also the standalone FireProtect 2 (CO). Prefer mains power? View the AC version.
What does the Ajax Hub add?
Every FireProtect 2 always sounds the alarm on site with its built-in siren. The benefit lies in the link with your Ajax system: via the Hub you receive an immediate notification on your phone, you can see which detector was triggered, and all detectors in the home warn at the same time. This way you hear a fire starting in the attic downstairs in the living room as well, and you also know about it when you are on holiday. If you have an alarm receiving centre subscription, follow-up can also take place there.
Do you have AirShield instead of Ajax?
Fire detection is also available within Dahua AirShield: the AirShield Smoke Detector (photoelectric sensor, siren of 85 to 90 dB) and the AirShield CO Detector with an LCD screen that shows the measured CO level. Both send a notification to your phone via the free DMSS app.
