Fire detection and devices (UL)

Siemens fire detection

The sooner you know about the fire, the sooner you can fight it.

The sooner a fire is detected, the sooner you can do something about it—evacuate people, alert first responders, and limit property damage. Our fire detection systems rely on innovative technologies and Siemens’ long history of experience and expertise in these areas.
