Does a smoke detector have to carry a VdS label?
No. The quality of a smoke detector cannot be ascertained from the name of the testing institute. The tests are precisely defined by the European standard EN 14604 and therefore are absolutely identical at all authorised institutes. “VDS recognised” or “VDS tested” are therefore not an additional quality criterium. Our smoke detectors carry the unique TÜV/Kriwan quality label and fulfil the important test criteria of the Smoke Detector System Standard EN 54, part 7: smoke detectors – circular detectors using the scattered light, transmitted light or ionisation principles.
Was this answer helpful? Yes No
Does a smoke detector need a Q label?
No. The Q label was created by manufacturers and is solely designed as an aid for consumers so that they can tell the difference between high quality smoke detectors and cheap products. The Q label is not awarded by a testing institute authorised by the European Commission nor does it meet the demands of a DIN or EN standard. The criteria for carrying a Q label are, for example, a long life and a lithium battery. As our PX-1 product not only meets these criteria, but also exceeds them (e.g. lifetime of over 10 years), we have so far not seen the need to add a Q label created by manufacturers to our unique TÜV quality label awarded by an independent testing institute.

Was this answer helpful? Yes No
Is it possible to change the battery in the PX-1 or do you have to throw the smoke detector away when the battery is flat?
The PX-1 smoke detector is fitted with a lithium battery which has a lifetime of at least 12 years and this is completely adequate. The centrepiece of the smoke detector is the photo-optic system in the smoke chamber. This component in our smoke detector changes over the years through a completely normal ageing process. The electronics in our smoke detector are able to recalibrate over the 12 years to compensate for this change and keep the trigger threshold for the alarm almost constant. After 12 years, this is no longer possible. We recommend replacing the smoke detector with a new one. Added to this there is, of course, the collecting of dust in the smoke chamber. As you can see, changing the smoke detector's battery to extend its lifetime would be completely meaningless.
Was this answer helpful? Yes No
What advantages does the permanently installed battery in the PX-1 offer?
The battery permanently installed in our detectors has the advantage that, apart from the stable electrical contact, it also offers security of use, as it cannot be removed from the detector by an unauthorised person and is therefore protected against deactivation. This an important criterium for landlords and property management companies who decide to use the PX-1 for rented properties. With its 12 year lifetime, the PX-1 is among the top products in the industry. The long battery lifetime is also an important contribution to environmental protection.
Was this answer helpful? Yes No
Which parameters – apart from smoke particles – does the PX-1 detect?
The PX-1 has bi-sensor processor technology for smoke and heat all in one device.
Was this answer helpful? Yes No
Can the PX-1 be joined in a wireless network and does it have VDE certification?
The standard PX-1 model cannot be joined in a wireless network. If in your other question you really mean VDE, we assume that this refers to DIN VDE 0833. This applies to hazard warning systems – but not to smoke detectors.
Was this answer helpful? Yes No



How much does it cost to purchase the smoke detector?
We offer our smoke detector PX-1 for sale at very reasonable and particularly competitive conditions and depending upon the quantity purchased.
Was this answer helpful? Yes No
Why do you only use battery-operated smoke detectors?
Battery smoke detectors have the same smoke-detector electronics as 220 volt mains smoke detectors. In both types of device, technically equivalent circuits check if smoke is present in the air. 220 volt mains smoke detectors are, however, around 10-20 times as expensive as battery-operated devices. In addition, the installation of the 220 volt detector takes a lot of time and is therefore costly, as each device requires its own 220 volt connection. Installation costs can easily exceed the costs of the device, so that a one 220 volt smoke detector can costs as much as EUR 100 for purchase and installation. To which is added, that the cable is often installed across the surface of the wall or ceiling and looks unattractive. The installation also involves noise and dust. 220 volt smoke detectors have a 9 volt emergency battery in case of an electricity outage, which has to be inspected once a year, as with battery smoke detectors, as they can discharge due to environmental influences. The lifetime of the sensor electronics for the very costly 220 volt smoke detectors is not better than those in battery-operated devices, which are very inexpensive. With both types of smoke detector, the device should be replaced with a new one after 5 years for low-cost devices and 10 years for high quality devices in order to avoid functional faults, as the electronics can become impaired due to corrosion, material fatigue, and a contaminated environment, which reduces the reliability of the smoke detector over time. In terms of cost and the time required, the maintenance needs of 220 volt smoke detectors is the same as with battery smoke detectors, because both devices and batteries have to be subject to a thorough inspection once a year for their functionality and performance. Also, professional cleaning of the interior and exterior of the smoke detector to maintain the reliable operational readiness is essential. Taking all the relevant aspects into account, the battery smoke detector is the clear winner, as it has the same functional quality and considerably smaller purchase and installation costs. In economic, quality and even ecological terms, the battery smoke detector is the better choice, as in the 220 volt smoke detector components are used for voltage conversion, the production and disposal of which are a heavy burden on the environment. Important tip: make sure that the smoke detector of your choice has a battery with at least 10 years lifetime. This saves you the annual battery change, as well as the related costs for expensive batteries. In this way, you not only save a lot of money, but you also prevent the environmental cost of the resulting annual battery change.

How often does a device go missing or has to be replaced due to vandalism?
Based upon data collected in previous years, we have calculated a statistical guide value that of 1000 homes, every year around 50 smoke detectors are either stolen or have to be replaced due to vandalism/renovation/home removal etc. Fluctuations in this value depend on the social structure.
Was this answer helpful? Yes No
Is there a quality assurance process?
es. We regularly personally carry out on-site quality controls and record telephone performance profiles at random, in order to constantly maintain the quality of our services at the usual high level for our customers.
Was this answer helpful? Yes No
Do the technicians remove their shoes in each home they visit?
Our technicians have plastic shoe covers, so that sensitive floor coverings are not dirtied. Equally, the requirements of Muslims are also met.
Was this answer helpful? Yes No

In which federal state are smoke detectors a legal requirement?
The first German states to have made the installation of smoke detectors in home a legal requirement as part of the state building regulations are Saarland and Rheinland-Pfalz. Saarland and the state of Thuringia have decided that bedrooms, children's bedrooms and escape routes in all new and renovated buildings have to be equipped with at least one functional ready smoke detector. According to the building regulations in the states of Schleswig-Holstein, Mecklenburg-Vorpommern, Hamburg, Rheinland-Pfalz und Hessen all existing homes (with transition periods) are to be retrofitted with smoke detectors. For new buildings the little life savers are an obligatory part of the inventory. The device's operational readiness is to be maintained after installation as per DIN 14676. Schleswig-Holstein: 31 December 2009. Mecklenburg-Vorpommern: 31 December 2009. Hamburg: 31 December 2010. Niedersachsen: 31 December 2015. Bremen: 31 December 2015. Berlin & Brandenburg: no regulations as yet. Saxony Anhalt: for all bedrooms, children's bedrooms and escape routes by 2015. Saxony: no regulations as yet. North Rhine-Westphalia: the socialist/green state government has agreed in its coalition agreement that this year smoke detectors will be obligatory in all flats and houses. Thuringia: 5 February 2008. Rheinland-Pfalz: 12 July 2012. Hessen: 31 December 2014. Baden-Württemberg: no regulations as yet. Bavaria: In Bavaria the obligation for smoke detectors are to be included in the state building regulations in 2012. This was agreed by the CSU, FDP and SPD parties in the state parliament on 18 April.

Aren't smoke detectors a matter for the tenant?
Smoke detectors are only particularly effective in blocks of flats if they are installed in all bedrooms, children's room and corridors and are always in a state of operational readiness. A fire in such a building can burn for a long time before it is detected by a smoke detector in a neighbouring flat. Consequently, the reaction to the fire is delayed. It is probable that this will result in injuries or even death. If the purchasing and maintenance of the smoke detectors is left up to the tenant, then a uniform equipment and maintenance structure will rarely be achieved. Operationally ready smoke detectors throughout the entire building can warn all residents with a 90 dB acoustic warning signal, even if the resident in the burning flat is not at home. Important: you usually have less than four minutes to leave a burning building!
Was this answer helpful? Yes No
How frequent are service and maintenance call-outs?
Based upon data collected in previous years, we have calculated a very reliable statistical guide value that of 1000 homes, every year around 50-60 service and maintenance call-outs caused by third party action (loss/vandalism) are to be expected. The number of call-outs which relate to a faulty smoke detector (false alarm) are extremely infrequent. Fluctuations in this value depend on the social structure.
Was this answer helpful? Yes No
Who is liable when it is established that the smoke detector did not trigger when there was a fire?
This very theoretical question is often asked. Such a case has NEVER happened. We do everything possible in the assiduous way we work to maintain the functional readiness of the smoke detectors. For the hypothetical and very unlikely case that all of the smoke detectors in a home stop working and are in involved in a fire, then we are not liable. Smoke detectors support early detection of a fire and can neither extinguish a fire nor prevent one. Our services are not a replacement for insurance. The obligations of insurers remain unaffected by our services.
Was this answer helpful? Yes No
Who is liable for a fire service call-out if the smoke detector makes a false alarm?
Based on our experience, there are a occasional cases that we know if where, for example, an insect or room spray has been used. As the the smoke detectors permanently measures the transparency of the surrounding air with a photoelectric cell, such spray mist can be interpreted as smoke by the electronics and thereby trigger an alarm. In certain cases other residents have heard the smoke detector alarm and have hastily alerted the fire service without checking whether there is a real fire. The person who does not check if there is actually a real danger and calls out the fire service is always the person liable for the costs of the call-out.
Was this answer helpful? Yes No
Where should a smoke detector be installed? And where not?
As the sense of smell is not active in people an animals when they are asleep, and because two to four breaths of toxic smoke can lead to severed brain damage or death, it is important that a smoke detector is installed in every bedroom on the ceiling and as far as is possible in the centre of the room. Furthermore, detectors should monitor escape routes, such as corridors and stair wells, and be placed every four to six meters. Additional protection can be offered by also installing smoke detectors in rooms which are not used as bedrooms or escape routes, such as living rooms and dining rooms. Smoke detectors do not belong in the kitchen or bathroom, as environmental influences such as large amounts of steam can trigger an unwanted false alarm. The hallway outside of the kitchen is a good place to install a smoke detector, because the proximity to the cooker and at the same time the distance from it means that an alarm is only triggered in real situations. Smoke detectors should always be installed for every 25m² of floor space and the distance between the devices should, if possible, be less than 6m. “In a room filled with smoke the visibility is down to zero. You cannot see your hand in front of your face, let alone the exit. It is therefore important to be aware of a fire early enough, so that you can escape”. Wolfgang Weiden, Chief of Operations of the Bergisch Gladbach Fire Service.

How are smoke detectors installed?
We have developed the Magnet Hot Glue Fusion Technique (MHF) which allows a smoke detector to be installed, as per DIN 14676, within a minute with the aid of our multifunction telescopic tool. Usually our technicians do not require a ladder. No electricity is needed, as the installation takes place without drilling and this also means neither dust nor noise are caused. The MHF technique employed leaves the building structure completely intact. When redecorating the device can easily be removed from the wall or ceiling. Even after the smoke detector has been removed there are no significant traces of the installation. Through the innovative installation technique described here we have reduced the installation of a battery smoke detector from an average of 8-12 minutes for installation involving drilling to less than a minute.
Was this answer helpful? Yes No
What does the installation of smoke detectors cost?
We do not bill our customers for the costs of installation and providing the smoke detectors needed if this is not expressly requested. We are solely responsible for the maintenance of our smoke detectors. We only bill for this maintenance service and nothing more.
Was this answer helpful? Yes No
Can the costs for the maintenance of smoke detectors be apportioned in the running costs?
Yes. With the corresponding contacts or notifications as per paragraph 560 German Civil Code the maintenance costs for the smoke detectors under paragraph 2, clause 17 R BetrKV (Running Costs Ordinance) can be included in the bill for running costs. As individual initial contractual situation varies, in each case a specialist lawyer should check the contractual conditions and define a path for apportioning the costs.
Was this answer helpful? Yes No
How often is the maintenance carried out?
The maintenance of the devices is carried out once a year as per DIN 14676. In this way, the optimum operational readiness of the smoke detector is always checked. Long maintenance intervals are not permitted in the above standard and would increase the danger of a smoke alarm either responding/alerting late in an emergency or not at all.
Was this answer helpful? Yes No
How long does it take to carry out the maintenance for a smoke detector?
Due to the intensive optimisation of the processes in the maintenance workflow and supported by highly developed recording technology, the maintenance of a device today lasts less than two minutes. In our engineering department we have developed special tools which allow our technicians to mainly work without ladders. This saves valuable working time and leads to a clear reduction in the risk of a workplace accident. Due to maintenance methods developed by us, the time needed for the maintenance of a battery smoke detector can be reduced from 5-7 minutes to less than two minutes. The considerable overall time saving is a factor in us being able to offer our services at a very low price.
Was this answer helpful? Yes No
What is done as part of the maintenance?
DIN 14676 defines the minimum scope of the maintenance for the user of the smoke detector, along with the installation location. So for example, it needs to be checked whether the device is undamaged, whether its air inlets are free of foreign bodies and the battery voltage is sufficient for another year. In addition, a test alarm should be carried out. With a great deal of care we perform what is demanded by this standard when we carry out our maintenance procedures. We check whether the smoke detector is still in its intended installation location, replace missing and damaged devices, carry out careful cleaning of the exterior of the device, so that no dust or foreign bodies can clog up the air inlets in the housing. We also check whether the device has sufficient battery voltage and perform a test alarm. For devices with a diagnosis connection, we read all of the performance and measurement parameters as well as the event recorder in the device and make the related diagnosis report as well as our proof of performance available to the customer via our customer portal.
Was this answer helpful? Yes No
What does the maintenance of the smoke detector cost?
The costs for the maintenance of our smoke detectors depend upon the duration of the maintenance contract, as well as the average number of devices installed. Example costs: per property per month: from EUR 1 inc. VAT. Per property per year: from EUR 12 inc. VAT. Per smoke detector per month: from EUR 0.29 inc. VAT. Per smoke detector per year: from EUR 3.50 inc. VAT.
