You can rely on the Ei650W smoke alarm. Whether stand-alone or networked with other Ei Electronics components, the detector impresses with maximum reliability - from the moment it is commissioned until the end of its service life. To ensure that alarms are triggered throughout the entire house, the smoke detector can optionally be networked by radio; the Ei600MRF radio module is available separately. Thanks to its long-lasting 10-year battery, the fire alarm provides reliable protection against fire hazards for the full 10-year service life. The device, which is manufactured in the EU, checks every 10 seconds whether there are smoke particles in the room air. As soon as this is the case, the smoke alarm device warns you immediately with its integrated 85 dB(A) piezo alarm. And because nothing is more annoying than frequent false alarms, the Ei650 is protected against disruptive incidents with soiling compensation. In addition, it does not require an LED or annoying flashing light and is completely suitable for use in bedrooms.

6. Ei Electronics Ei208D Carbon monoxide alarm
It is invisible, odorless, and tasteless: Carbon monoxide (CO) is a dangerous respiratory poison that is produced during the incomplete combustion of carbon-containing materials. What helps here is to buy a CO detector. A carbon monoxide alarm like the Ei208D from Ei Electronics provides the only effective protection against potentially fatal CO poisoning. This detector, designed for a lifespan of 10 years, checks the CO levels in the surrounding air every 4 seconds and reliably warns as soon as danger arises. The use of such a CO detector is particularly sensible in places where combustion appliances such as fireplaces, pellet stoves, briquette heaters, oil heaters, gas boilers, gas heaters, or instantaneous water heaters are used. The battery-operated Ei208D is designed as a CO alarm for flexible installation in living spaces and can also be used in recreational vehicles such as motorhomes, caravans, or boats. If the electrochemical sensor of the Ei208D detects elevated CO levels, the integrated LCD display of the alarm provides specific instructions on how to best respond to the danger.
