What alternatives are there to the Ei Electronics smoke detector ei650?

As an alternative to the ei650 smoke detector from Ei Electronics you can also purchase a smoke detector from another manufacturer. The models of the following manufacturers have also performed well to very well in test comparisons:

X-sense SD11
Hekatron Genius Plus
Smartwares RM620

All these models have in common that they are equipped with a 10-year lithium battery. Depending on the application, the different smoke alarms offer specific advantages. For example, if you are looking for a smoke detector for a motorhome, the Smartwares RM620 is particularly suitable, as it has a function to pause the smoke detector for 10 minutes, for example to cook.

Purchase criteria: These factors allow you to compare and rate the Ei Electronics smoke detector (ei650)

You can rate the Ei Electronics smoke detector (ei650) according to the following criteria:

  • Product Lifetime
  • Radio networking
  • Test and mute function
  • Disassembly lock

In the following paragraphs we will explain what the individual criteria are and what features the Ei Electronics smoke detector (ei650) has.

Product Lifetime

The Ei Electronics smoke detector has a product life of at least 10 years. This is ensured by the permanently installed lithium batteries, which last approx. 10-11 years. During this period the smoke detector requires very little maintenance. Due to the contamination compensation the sensitivity of the smoke detector automatically adapts to contamination in the smoke chamber. This prevents false alarms. At the same time, a reliable warning protection remains in place in case of smoke development.

If the batteries start to weaken after 10-11 years, a warning signal sounds. Then the device must be replaced because the batteries cannot be changed.

Radio networking

The smoke detector models ei650W and ei650C can be networked with each other via radio. The latter model can also be networked by wire. This is particularly practical if smoke detectors are distributed throughout the house. This way all smoke detectors alarm simultaneously if smoke develops in a room.

This provides increased security for your home. In this way you can detect a possible fire very quickly and take immediate action. In case of false alarms, it is also sufficient to switch off only one device. The command is transmitted to all other smoke detectors via radio link.

In total, up to 31 smoke detectors can be networked together. A subsequent attachment of the radio modules is also possible with only a few simple steps.

Test and mute function

The Ei Electronics smoke detector (ei650) has a large test and mute button in the centre of the unit. This facilitates operation from the ground. In the event of a false alarm you can easily and quickly reach the mute button. You can easily reach the button with an elongated object (such as a broomstick or umbrella) without having to climb a chair or ladder.

This allows you to switch off the false or test alarm within a short time without having to search for the off button. After muting the smoke detector is deactivated for 10 minutes. During this time the red LED flashes every 8 seconds. The smoke detector will then function normally again.

Disassembly lock

The Ei Elecronics smoke detector (ei650) also has a dismantling safety device. This ensures that the smoke detector cannot be removed by unauthorised third parties. To do this a small bar is broken out of the mounting base.

To remove the smoke detector it is now necessary to loosen a small hook using a screwdriver. If necessary, the smoke detector can also be attached firmly to the mounting plate by using thread-cutting screws

Trivia: Worth knowing facts about Ei Electronics smoke detectors

Now that you have gathered enough information about the Ei Electronics smoke detector (ei650), we would like to conclude by giving you some more information and tips.

What accessories do I need for the Ei Electronics smoke detector?

The smoke detector ei650 is a stand-alone device. With this model you do not need any additional accessories. The batteries are already built into the device.

For the models ei650C and ei650W you still need an appropriate radio module for wire or radio networking. This can be fitted to the smoke detectors at a later date. You can also purchase the following optional accessories:

  • Ei450 Alarm Controller for easy operation of radio networked smoke detectors.
  • Ei407A emergency warning button for manual alarm triggering in the smoke alarm system.
  • Detector protection basket Ei117 to protect the smoke detector from the effects of violence.
  • Coupling / input / output modules (Ei413, Ei414, Ei408, Ei42), for linking the networked smoke alarms with an external system.

How does the Ei Electronics smoke detector perform in the Stiftung Warentest?

The Ei Electronics smoke detector ei650 is multiple test winner at the Stiftung Warentest (1/2016, 1/2013, 11/2002)

Due to the integrated 10-year lithium battery, the large test and mute button and the unlimited bedroom suitability, the smoke detectors have been distinguished as particularly reliable and user-friendly.

What guarantee does Ei Electronics give on its smoke detectors?

Ei Electronics gives a 5-year manufacturer’s guarantee on its smoke alarms. At the same time Ei Electronics promises a function duration of the smoke detectors of at least 10 years.

If you have questions or problems regarding smoke detectors, you can also contact customer service. They are available by telephone or e-mail. The contact details can be found on the manufacturer’s website.

Since when does Ei Electronics produce smoke detectors?

Ei Electronics has over 50 years of experience in the manufacture of smoke alarms. This makes the company the European market leader for smoke alarms in private homes.

The company has its roots in Ireland, the “green island”. This is where the name “egg” came from, which stands for “Emerald isle”. The company emerged from the multinational General Electric and has been owner-managed since 1988.

Where are Ei Electronics smoke detectors (ei650) manufactured?

Ei Electronics smoke detectors are manufactured entirely in its factory in Shannon (Ireland). The smoke detectors are the result of 100% in-house development and therefore stand for highest quality. Each detector is tested and calibrated several times under real smoke or carbon monoxide before it leaves the factory. This makes the products particularly reliable and makes Ei Electronics the quality leader on the European market.

What other products does Ei Electronics offer?

In addition to smoke detectors Ei Electronics also has carbon monoxide detectors and heat detectors in its range.

Carbon monoxide alarms provide reliable protection against CO hazards. This is a dangerous respiratory poison that can only be detected with the help of technical sensors. Such a dangerous situation arises, for example, if there is a technical defect in the heating system or the chimney is clogged. In this case, a carbon monoxide warning device reliably warns of the life-threatening danger.

Heat detectors, on the other hand, are particularly suitable for the kitchen. They trigger an alarm as soon as the ambient temperature exceeds 58 °C. Since a conventional smoke alarm in the kitchen would lead to frequent false alarms due to cooking fumes, it is not suitable for this purpose. The heat detector is therefore a good alternative and can be extremely useful as a supplement in a wire or wireless networked system.
