1. Ei Electronics Rauchwarnmelder 10er Set
The Ei Electronics Ei650 smoke alarm is a reliable security system that comes in a practical set of 10. These battery-operated detectors are specially designed for indoor use and offer an effective way of detecting potential fire hazards at an early stage. With an integrated 10-year battery, they guarantee long-term use without frequent battery changes. The visual warning signals and the high sound power level of 85 decibels ensure that attention is quickly drawn to the danger in an emergency. Compatibility with smart home systems enables easy integration into existing security solutions without the need for an additional hub. This set is ideal for households that prioritise security and prevention.

2. Ei Electronics Rauchwarnmelder
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.

3. Ei Electronics Radio module incl. 10 year bat
For installation in smoke detectors of the series Ei650W, Ei650iW, Ei650C, and Ei650iC, as well as in heat detectors of the series Ei603TYC. This device is used for networking smoke detectors and heat detectors and operates at a radio frequency of 868 MHz, features individual house coding, and has an easy input function.

4. 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.

7. Ei Electronics Ei414RF - 868.499 MHz - 100 m - AC - 230 V - 0 - 40 °C - 0 - 35 °C
The Ei414 can deliver either a pulse signal or a continuous switching signal through the relays to the universal transmitters. A dip switch also allows for a delayed timed response. The specific signal type is determined by the requirements of the OEM universal sensor.
The Ei414 contains three mains voltage relays (up to 250V AC / 5 Amperes). The relay contacts operate with mains power or with battery backup in the event of a power failure.
The Ei414 features a 3-way key switch. In the "On" mode, the Ei414 responds to a "Fire" or "CO" signal. In the "Off" mode, the Ei414 does not respond to RadioLINK signals. In the "Test" mode, the Ei414 only responds to a "Test Signal" or a "Repeated Remote Test Signal" (e.g., from an Ei450 or Ei412). Upon receiving a test signal, the corresponding relay (Fire or CO) is activated. Upon receiving a repeated remote test signal, the fire relay is activated.
The Ei414 uses RadioLINK multi-repeater, multi-path technology to ensure very robust and reliable RF signal coverage. Although it is primarily designed for interfacing with a Warden Call or similar telecare system, the versatility of the electrically isolated contacts of the Ei414 means that it can also be used to switch many other OEM devices.
