Wirelessly linked to your AJAX alarm
Fire and water detection with AJAX
Fire and water detection with AJAX lets you spot smoke, heat, carbon monoxide (CO) and water leaks in time. The wireless detectors work together with your AJAX alarm system and send an instant notification to the AJAX app.
RRB Security advises which detectors suit your home or business premises, installs them and links them to your existing or new AJAX system. We are happy to visit you, with no obligation.

Components
What does AJAX fire and water detection consist of?
The detectors work wirelessly with an AJAX hub and are available in different versions, in terms of both detection and battery. Together with you, we choose the components that suit your rooms. Below, you will find an explanation and the specifications for each component.
Fire detectors

FireProtect 2 smoke and heat detector
Detects smoke and a rapid rise in temperature, even in a fire without smoke. The dual-spectrum optical sensor and the HazeFlow 2 algorithm respond only to smoke and ignore cooking fumes and steam.
Specifications
- Dual-spectrum optical smoke sensor
- HazeFlow 2 distinguishes smoke from vapour and steam
- Heat alarm at a rise of 10 °C within a minute or above 64 °C
- According to AJAX, suitable for residential fire safety standards
- Available as a heat, smoke, CO or combined detector

FireProtect 2 CO detector
Measures carbon monoxide (CO) and raises the alarm before the first signs of poisoning appear. You see the alert straight away in the AJAX app.
Specifications
- 50 ppm within 90 minutes
- 100 ppm within 40 minutes
- 300 ppm within 3 minutes
- Also available as a combined smoke, heat and CO detector

Built-in siren
Every FireProtect 2 has a powerful 85 dB siren. From the tone pattern, you can tell straight away whether it is a fire, CO, a fault or a low battery.
Specifications
- 85 dB
- Separate tone pattern for heat alarm, dangerous CO level, fault, low battery and end of life
Water detection and automation

LeaksProtect flood detector
Sends an instant notification if your washing machine leaks or a pipe bursts. The detector needs no installation and also fits in hard-to-reach places.
Specifications
- Battery lasts 5 years
- IP65 housing
- Works 24/7
- Instant push notification, siren possible

Smart plug and built-in socket
Automatically switches off the power to, for example, the washing machine when a leak is detected. This limits water damage.

Relay and wall switch
Also control gates, roller shutters and lighting from the same app, so detection and automation work together.
Connection

AJAX hub and Jeweller
The detectors send their alarm to the hub via AJAX's Jeweller radio protocol. The protocol is secure and energy-efficient, so the batteries last for years.
Specifications
- Synchronised communication
- Authentication against spoofing
- Encryption against data theft

Interconnected fire alarm
In a fire, the hub sets off the sirens of all FireProtect detectors within 20 seconds. If the connection with the hub is lost, the detectors warn each other directly.
Specifications
- Primarily via the hub: all sirens within 20 seconds, according to AJAX three times faster than the standard requires
- Fallback without the hub: alarm within 1 minute
- Location, alarm type and time straight in the app
Battery and app

SB version
With a built-in battery that never needs replacing.
Specifications
- 10 years of operation
- Non-replaceable built-in batteries

RB version
With batteries you can replace.
Specifications
- Up to 7 years of operation
- Replaceable CR123A batteries

Notifications in the AJAX app
All notifications arrive in the free AJAX app for iOS and Android and in the software for Windows and macOS. A detector warns you at least 30 days in advance when its battery is running low.
Specifications
- Battery warning at least 30 days in advance
- LED indicator and beeps when the battery is low
- App for iOS and Android, software for Windows and macOS

Advice
What to consider with fire and water detection
Good placement starts with an assessment of your rooms and how they are used. We include the topics below in our advice.
Smoke, heat or CO detector?
A smoke detector is the basis for bedrooms, corridors and living areas. Where smoke or steam is normal, such as in a kitchen or garage, a heat detector may be a better fit. Near a central heating boiler, gas water heater or open fire, we recommend a CO detector. A combined detector brings these together in one device.
How many detectors do you need?
That depends on the number of floors, the escape routes and how the rooms are used. We determine this with you on site.
Where do you place a flood detector?
On the floor near places where leaks can occur, such as the washing machine, dishwasher, central heating boiler, hot water cylinder, bathroom and toilet. The detector needs no installation.
SB or RB: which battery?
The SB version has a built-in battery and works for up to 10 years without a battery change. The RB version uses replaceable CR123A batteries and lasts up to 7 years. We advise which version suits your maintenance preferences.
Automatic action on a leak
With an AJAX smart plug or relay, the power to, for example, the washing machine can be switched off automatically when a leak is detected.
Who receives the notifications?
In the AJAX app, you decide who receives which notifications. You see the location of the detector, the type of alarm and the exact time.
Home or commercial premises?
The FireProtect 2 works within an AJAX alarm system and is made for homes. If you need fire detection to EN 54 for commercial premises, we recommend the AJAX EN54 fire alarm system.
Expanding with intrusion, cameras and a doorbell
Fire and flood detectors work in the same AJAX app as the alarm system, video surveillance, the video doorbell and smart plugs. That way, you manage everything in one place. Read more under AJAX alarm system, CCTV camera kit and Video doorbell.
Frequently asked questions
Frequently asked questions about AJAX fire and water detection
Can't find your question? Our specialists are happy to help with advice that fits your situation.
What is the difference between the FireProtect 2 and the AJAX EN54 fire alarm system?
The FireProtect 2 is a smoke, heat and CO detector within an AJAX alarm system for homes. The AJAX EN54 fire alarm system is a fire alarm system for commercial buildings, with its own control panel. We advise which solution suits your building.
Does the smoke detector give false alarms when cooking or showering?
The FireProtect 2 uses a dual-spectrum optical sensor and the HazeFlow 2 algorithm. This lets the detector distinguish smoke from vapour and steam.
How long do the batteries last?
The FireProtect 2 works for up to 10 years (SB version, built-in battery) or up to 7 years (RB version, replaceable CR123A batteries). The LeaksProtect lasts 5 years. The FireProtect 2 warns at least 30 days in advance when the battery is running low.
Do I get a notification on my phone if there is a water leak?
Yes. The LeaksProtect sends an instant push notification via the AJAX app and can also set off a siren.
