Having the right fire protection saves lives. This overview of the most frequently asked questions about the MOBS technology, leasing arrangements and general information should help you answer your initial questions.
General questions about the MOBS mobile fire alarm system
How much does it cost, and where can I buy MOBS?
Different costs are involved, depending on whether you decide to buy or lease a MOBS system. We'll be happy to advise you and provide you with the current price list. Simply call us on +49 7054 9323-0 or send an e-mail to email@example.com.
Which rules and regulations are involved?
Different legal regulations and requirements prescribe when a fire alarm system is required. Depending on the sector of industry involved, compliance with additional, special regulations may be required. Here is an overview of the most important regulations:
Arbeitschutzgesetz (ArbSchG) - German occupational safety regulations
Arbeitsstättenverordnung (ArbStättV) - German work safety regulations
Bauproduktverordnung - German construction products regulation
EN 54 Fire detection and firer alarm systems
European norms for the use of radio technology as part of emergency equipment (ETSI 300-220-1)
Technical regulations for workplaces, ASR A2.2
Accident-prevention directive – principles of prevention, DGUV regulations
VdS 2021 (guideline for a comprehensive protection concept for building sites)
When is a mobile fire alarm system a requirement?
Mobile fire alarm systems have many areas of application, such as on building sites or as an interim solution when existing systems are being upgraded. Mobile fire alarm systems can also ensure the required levels of safety in other areas that are at risk of fire, such as public buildings, hospitals, at shipyards or aeroplane construction factories, and even at public events.
You will find more information in the sections about specific applications.
What options does a MOBS system have for creating documentation?
In addition to creating maintenance reports, every MOBS system can be monitored from the mymobs.de platform. This enables you to check your system from almost anywhere in the world. All you need is Internet access.
This means you can create legally watertight documentation about compliance with fire protection regulations at any time.

Technical questions about the MOBS mobile fire alarm system
How many detectors do I need?
The number of detectors depends on the size of the premises and its interior spaces. You also need to consider what is to be monitored and what you want to protect.
In Germany, DIN VDE 0833 allows for a maximum of 32 detectors per system. Up to 63 radio detectors can be connected to a MOBS detector receiver.
We are guided by the relevant standards for building sites. That is why we recommend between 30 and 40 radio detectors per system.
Can I also send SMSses?
Yes, although it is technically possible to send SMS messages, we don't recommend it. This is because the service is always dependent on the network and can therefore be delayed or not arrive at all.
Do I always need a detector receiver?
Yes, a detector receiver is a requirement, because it controls the radio smoke detectors (FRMs) and bundles their signals. If you use a large number of FRMs, you can connect several systems to one MOBSbus.
In every case, switch contacts for connecting to an existing fire alarm system are present. These also enable the system to inform the Fire Brigade or security firm.
How big is the detector’s range?
MOBS has a much greater range than other radio fire alarm systems. Safety is a subject close to our hearts, which is why we have focussed so strongly on ensuring a especially big range between radio smoke detectors and the receiver unit. In open countryside, it is 1800 m, and in town it is between approximately 70 and 300 m.
Do I need special batteries for the radio smoke detectors?
No, the radio smoke detectors in every MOBS system use normal batteries. This reduces running costs to a minimum.
Can I connect the MOBS to a permanently installed fire alarm system?
Yes, every MOBS system has the switch contacts it needs to connect to an existing fire alarm system. Your specialist installer, who will also assemble the system, can also set up this connection for you.
Which detector components are needed?
MOBS consists of a combination of radio smoke detectors (FRMs) and a detector receiver (either an optical-acoustic receiver or a portable receiver). The FRMs can be fitted with a multitude of different fire detectors.
Not only do they comply with the standard, but they are highly efficient in avoiding false alarms. When the detectors detect a fire, they send an alarm message to the detector receiver via radio.
It may also be necessary to inform the Fire Brigade or security firm immediately, as well as anyone present on-site. There are several different ways to retransmit alarms:
switch contacts for connecting to an existing fire alarm system
with an automatic dialler and voice announcement to a telephone subscriber
to an emergency call service control centre, using an automatic dialler and the VdS 2465-S2 protocol
with (analogue or digital) professional mobile radio and voice announcement or text message to a patrol
by displaying it on the new browser-based MyMOBS.de platform.
Note: We do not recommend alarm retransmission via SMS because the delivery time is not guaranteed.
Questions about leasing a MOBS mobile fire alarm system
Do I need special training so that I can use it?
You don't need any special training. The system is designed to be intuitive and user-friendly. However, if asked, we'd be happy to arrange an introduction to how to use the MOBS system, just to make sure.
What happens if a leased MOBS system gets damaged?
Any damages (unless malicious) is covered by the leasing fee and its associated insurance policy.
Is there a limit to the leasing period?
There is no limit to the amount of time you can lease a MOBS system. However, if it's in regular use over a longer time period, there will come a point at which it makes more financial sense to purchase one. A leasing period doesn't usually run to more than 36 months.
