Smoke alarms
from QUNDIS
Smoke alarms, also known as fire alarms or smoke detectors, detect smoke in the event of a fire and trigger an alarm. They attract the attention of anyone in the vicinity with a loud beeping noise and a visual signal.
Because smoke alarms are naturally subject to the accumulation of dirt, their functional capacity diminishes over the years. This is not the case with our products! Our devices compensate for any accumulation of dirt by automatically adjusting the basic signal. This provides them with two and a half times the product life of smoke alarms without this compensation function. Thus, false alarms will be avoided for the most part. Thanks to the integrated battery, the QUNDIS smoke alarms achieve a durability of at least 10 years.
The result: smoke alarms from QUNDIS are 100% reliable and also fulfil strict quality requirements.
Safety & ease of operation in perfect harmony.
The Ei6500-OMS expands the QUNDIS portfolio with a 4th generation wireless smoke alarm in accordance with the OMS standard. With the permanently installed 3V lithium battery as well as the wM-Bus remote inspection module, this smoke alarm is ideally suited for entirely remote inspection in accordance with DIN 14676-1 Method C.
Thanks to the regular, automatic functional self-test as well as wireless radio transmission, an annual on-site inspection is no longer necessary, as the relevant data can be conveniently transmitted remotely at any time. For example, data relating to the energy supply, smoke sensors or disassembly as well as other status messages that are functionally important. Existing processes can be simplified in this way, thus saving costs.
System integration is extremely simple: after being screwed into the base, the smoke alarm automatically goes into operation and sends data telegrams to the QUNDIS Q AMR or Q walk-by system. The high security standard is guaranteed by the AES-128 data encryption according to OMS-Encryption Mode 5.
With QUNDIS and the Q SMP, key management is also uncomplicated. After you place your order, you will receive an electronic QUNDIS delivery note (eLS, csv file) by email or you can download it conveniently via the QUNDIS customer portal. Alternatively, you can also retrieve the eLS via an API interface. After successful eLS import, automatic decryption can then be carried out in the Q SMP. All you need is a corresponding Q SMP tariff from QUNDIS.
Reliable and safe.
The Ei650i stand-alone smoke alarm is a real star in terms of quality and reliability, and has already proven itself in use millions of times over. In addition to the EN 14604 product standard, it also complies with vfdb directive 14/01 and therefore meets the strict requirements of the “Q” seal (tested and certified by VdS, test number G211009). It is thus one of the leading quality products on Germany’s smoke alarm market.
In order not to disturb the night’s rest of occupants, unwanted LED flashing is suppressed. The smoke alarm also has integrated dirt compensation and, in addition to the proven features of the Ei650, has additional functions such as an extended muting function and special diagnostic features.
It can be mounted directly on the ceiling using one or two screws. Alternatively, the Ei650i can be fitted to the existing Ei smoke alarm mounting plates of the Ei650 or Ei605 series.

Our smoke alarms work on the scattered light principle. When smoke reaches a certain concentration, the light in the device is directed onto a photocell, triggering the audible alarm. The test button on the Ei650i smoke alarm can be used, for example, to check whether one or more alarms have been triggered within the last three months. In addition, the LED flashes to indicate the status. For optimal protection, you should install a smoke alarm in every room where a fire could potentially break out (except for kitchens and bathrooms).
The national application standard DIN 14676 regulates the planning, installation, operation and maintenance of smoke alarms. This standard applies to private homes and rooms with similar residential use. It is intended for the authorities responsible for fire protection, fire brigades, smoke alarm manufacturers, planners, homeowners and residents. Important to know: Only smoke alarms that fulfil the requirements of EN 14604 may be used in the EU.
Furthermore, the state building regulations (LBO) of the individual federal states regulate the obligation to equip existing and new buildings with smoke alarms.
Before smoke alarms became popular in the domestic sector, smoke detector systems were almost the only ones to exist in Germany (e.g. in hospitals, warehouses, hotels). The government created a corresponding standard early on, in which the detectors were referred to as smoke detectors. However, these detectors were not designed to warn people of dangerous smoke concentrations by beeping loudly, but to report a fire directly to the fire brigade – even if there were no people in the building.
With the increasing prevalence of smoke detectors in homes, it was found that the name was already taken. From then on, the acoustic warning devices were called “smoke alarms”. Even if the term smoke detector is used, in most cases it refers to a smoke alarm. Our portfolio includes only such smoke alarms.
Please note that the lifespan of a smoke alarm device is 10 years. The long service life is achieved by a permanently installed lithium battery and increases safety. This is because you no longer have to worry about regularly changing batteries. Furthermore, the device must have a CE marking. This proves that the smoke alarm device complies with the European device standard EN 14604 and has been tested and approved according to its strict criteria.
The coveted ‘Q’ label is only awarded to devices that meet the particularly strict standards. The ‘Q’ stands for the highest quality of smoke alarms. This seal of approval provides information on whether a smoke alarm is suitable for long-term use over a period of 10 years.
The application guideline DIN 14676 stipulates how a smoke alarm device is to be installed. The following key points provide an initial overview of some of the most important requirements:
Important: the QUNDIS smoke alarms with an integrated radio module do not replace a central fire alarm system. If, in the event of smoke or fire detection, an alarm is to be forwarded to the fire brigade, a central fire alarm system must be used in accordance with DIN 14675.
Smoke alarms are not suitable for bathrooms or closed kitchen areas. They should be at least 90 cm away from kitchen and bathroom doors, compressed air lines for air conditioning systems or heating systems, ceiling fans and house fans.
Likewise, smoke alarms should not be installed in very dusty areas (e.g. workshops). During renovation work that involves a lot of dust, you should cover the smoke inlet openings of the devices until the work is finished or remove the devices completely. Never paint over smoke alarms!
When the test button is pressed, the indicator light flashes at regular intervals to show that the smoke alarm is working. In the Ei650i, the LED brightness is automatically reduced from 10 p.m. to 6 a.m. In the Ei6500-OMS, there is no signalling during normal operation. Fault messages are suppressed during this time in the Ei650i and signalled continuously in the Ei6500-OMS; an alarm is still raised in an emergency.
When the Ei650i or Ei6500-OMS is screwed into the previously attached mounting base, the device is automatically activated. An audible signal confirms that it is ready for operation.
During the remote inspection, the smoke alarm device transmits the necessary status information about its operating state to the radio network in the building. This information allows the landlord to see very early on if a device is faulty. The device can be replaced directly, for example, during the annual visual inspection.
The following status messages regarding handling and operating status are transmitted by the radio-controlled smoke alarm Ei6500-OMS to the remote meter reading system:
High quality smoke alarms, such as those produced by QUNDIS, do not register cigarette smoke, because they recognise the difference between cigarette smoke and the very small but dangerous concentrations of smoke which may be present in buildings. Thanks to the inbuilt dirt compensation, this mechanism works reliably over the entire lifespan of the device.
Dirt compensation
Our smoke alarms permanently monitor the dirt in their measuring chamber. If dirt particles are detected in the measuring chamber, they adjust their alarm threshold so that the distance to the basic signal always remains the same. The smoke alarms from QUNDIS do not become more sensitive due to dirt, which means that the operating time is increased many times over. As a result, false alarms can be avoided to a large extent.
Dirt prediction
Our smoke alarms can determine the state of their measuring chamber through a process known as alarm threshold adjustment. At regular intervals, the device measures how much the measuring chamber is clogged with dirt particles – the higher the level of contamination, the further the alarm threshold is lowered. During the annual function test, the devices automatically generate a forecast as to whether they will continue to function properly for another 15 months if the level of contamination remains the same. If the forecast indicates that the contamination of the measuring chamber is so severe that the alarm threshold can no longer be adjusted, the function test will fail.
