Test alarm in Dresden: Sirens will sound on July 9th for safety!
On Wednesday, July 9, 2025, things will get loud again in Dresden: at 3 p.m. the sirens will wail across the city for about twelve seconds. This test alarm is an integral part of the regular checks of the warning system, which can be crucial in an emergency. As dawo-dresden.de reports, the signal consists of a single increase in the tone, followed by a hold and then a decrease and a final gong.
Dresden has a state-of-the-art siren warning system equipped with 210 locations. This modern infrastructure was extensively modernized after the flood events in 2002, 2006 and 2013, as the city administration explains in a press release: dresden.de. A special feature is that the sirens are operational for up to 48 hours in the event of a power outage thanks to battery backup. They can not only emit beeps, but also voice announcements, which is particularly helpful in emergency situations.
Regular tests and nationwide participation
The regular test alarms take place four times a year on the second Wednesday of each quarter. The next test date after July 9th will be October 8th, 2025. The population does not have to take action in these cases, but it is helpful to inform neighbors and passers-by about the test alarm, as the city recommends. This information is part of a broader strategy that also includes Dresden's participation in the nationwide warning day on September 11, 2025.
A siren funding program was launched with the aim of improving the siren infrastructure in Germany. According to [bbk.bund.de](https://www.bbk.bund.de/DE/Warnung-Vorsorge/Warnung-in-Deutschland/So- Werden-Sie-gewarnt/Sirenen/sirenen_node.html), whether cities and municipalities have sirens depends on local decisions. The federal government provides funding to modernize existing systems and purchase new ones. For example, the program promotes self-sufficiently operated sirens that also work without a public power supply. These developments are particularly important with regard to the future of warning infrastructure.
In today's world, when various means of emergency communication work in coordination with one another, the siren system remains a central warning channel. Combined with warning apps and radio broadcasts, the sirens can make a valuable contribution to the safety of the population. Dresden is well positioned to ensure the safety of its citizens both in everyday life and in emergencies.
Further information about the sirens and how they work will be provided via the social media channels of the city and the Dresden Fire Department so that all citizens can always stay informed.
