Simple, slim and smart: Not only the inner values of the iHaus smart home smoke detectors are heroic, they can also be seen everywhere. With the subtle modern design and the compact size, they seamlessly fit into every room.


Dual safety with heat and scattered light measurement


VdS-certification DIN EN 14604 DIN 14676 Q label test certificate CE mark


The modified Hager smoke detector TG551A from iHaus has been awarded with the VdS certification and Q-Label, showing that it fulfills the highest standards as heat and smoke alarm. So different types of fire can be quickly recognized and you can always rely on your smart fire experts at home. The smoke detectors are suitable for rooms, houses, apartments, practices, hotels, restaurants, commercial and offices.


Top quality by VdS & Q-label

The Q stands for quality of smoke detectors. The independent Q-label distinguishes high-quality alarms, which are particularly durable and proven to be very safe. Preceded by the CE mark, it supplements the European product standard DIN 14604.

Fire detection via heat measurement

The fire detector detects heat development with the integrated temperature sensor. The detector feels rapid temperature changes in case of liquid fires for example, and warns particularly in the kitchen and bath or in the chimney area..

Smoke detection via scattered light measurement

The second functional principle of the smoke detectors is the optical scattered light measurement. It detects very small smoke particles in the air. This principle has proved itself particularly useful in combating smoldering fires, which are slowly spreading.




Alarm and alarm stop by wireless push button detector

hager-TG558B und hager-TG558A

TG558-A and TG558-B are radio and push button detectors designed to integrate into an existing smoke detector radio network for manual alarm triggering or alarm reset. A tool-free push-button combination integrates both accessory devices into the smoke detector network.

Both systems serve the scope of e.g. Practices, law firms, businesses, hotels or similar applications. The use of the pressure detection button can be replaced separately after approx. 10 years after the low battery warning.



Smoke detectors linked with the smartphone alert for more security

With radio-linked smoke detectors, your home is even better protected. The radio-link simultaneously triggers an alarm on all smoke detectors. It doesn’t matter in which room heat or smoke was detected. Additional the iHaus App can send an alert to your smartphone in real-time. Even your family and loved ones can be informed directly in the event of an alarm with a push message or e-mail.

Ideal protection for your home

Smoke detectors are now compulsory in most German states. Also several European countries have submitted new smoke detector regulations, such as France, Belgium, Netherlands and the UK. According to legal requirements in Germany for example, they are to be installed in the bedrooms, children's rooms and in the corridor. As a dual smoke detector with heat detection, the iHaus fire detector is also suitable for the kitchen. In order to avoid false alarms caused by harmless smoke and steam during cooking, the optical scattering light function on the smoke detector can be deactivated. Instead, the heat detection provides protection from fires in the kitchen. The thermo sensors alert you in case of a very fast heat development.
