Smoke & Fire Alarms

Discover a wide range of smoke detectors for your specific needs at Conrad. Find out all about fire detectors and smoke detection requirements in our guide. 

Show more than 400 fire deaths annually and about 210,000 reported fire losses in 2014 alone: Don't ignore fire protection in your household! Reliable, tested smoke detectors are already available for under 10 euros, can be installed easily without drilling and include batteries with up to 12 years service life .

Smoke detectors in living rooms warn of danger at an early stage

Smoke detectors and heat detectors are combined under the term " fire detectors ". Smoke detectors detect even the smallest smoke particles in the monitored room through the scattered light process. For this reason, smoke detectors must be available throughout Germany in all living and sleeping rooms, children's rooms and corridors.

How does a smoke detector work?

A light diode emits a light beam that is broken by the smoke particles and thrown back into the device. There, the light beam hits a sensor that triggers the alarm.

Higher-quality smoke detectors have a laser diode that reacts to even smaller particles and therefore trigger an alarm at an early stage.

Differences between smoke detectors and heat detectors

Smoke detector:

• Detects the smallest smoke particles and triggers an alarm
• Statutory smoke detection requirements in all federal states
• Mostly battery operation, uncomplicated maintenance
• Easy installation without drilling

Heat detector

• Respond to high temperatures and temperature increases
• Fire protection for kitchens and other damp-warm rooms
• Detect even the smallest temperature differences early on
• Mostly battery operation, uncomplicated maintenance
• Easy installation without drilling

Heat detector only for kitchens and damp-warm rooms

Heat detectors, also known as heat detectors, react both to exceeding a maximum temperature (usually 60 °C) and to a significant increase in temperature within a short time (usually 5 °C within 3 minutes) by means of built-in temperature sensors. A thermistor located inside the unit measures the temperature in the room and compares it with a reference.

As the greatest danger for us is usually not fire, but smoke development, heat emelters should only be used in warm, moist rooms with particulate-laden air, mainly in kitchens, garages and workshops.

Certifications and Standards: When purchasing fire detectors, make sure that they are certified. Important quality features are the certification of the TUV, the equivalent of DIN, the recognition according to the European product standard EN 14604, as well as the VdS.

Smoke detector test spray: Smoke detectors should be checked for proper operation during reinstallation and annual maintenance. Special test sprays are available for this purpose, which trigger an alarm if the smoke detector functions correctly.

Network connectivity: Many fire detectors can be networked wirelessly via radio. If one of the devices detects a fire, all connected detectors trigger the alarm signal. A separate radio control center is optionally used to control and monitor the individual fire detectors. Wireless remote controls allow you to manually turn off a triggered alarm or trigger a test alarm.

Emergency light: More and more smoke detectors have an emergency light. In the chaotic situation of a fire, it is intended to serve as a guide and make the escape route easier to find.

Smoke detectors are the best choice:

• For all living rooms, bedroom and children's room, corridors
• For rooms without damp heat and particle load in the air
• For reliable protection of persons

Networked fire detectors are the best choice:

• For larger apartments and houses with several floors
• Provide additional security as all fire detectors trigger an alarm
• Can be realized by cable or wireless via radio and can be extended (radio center, remote control)

Heat detector is the best choice:

• For kitchens, garages, workshops
• For all humid rooms with particles in the air, which are not living/sleeping rooms
• For property protection and as a supplement to smoke detectors in the household

Cable-powered fire detectors are the best choice:

• If you are planning the system for new/retrofit
• If it is to be connected to an alarm system
• If the fire detectors are to be connected to other devices
