Prevent the spread of fire through automatic door release

In busy environments, such as hospitals or schools, it is often necessary to have doors held open, but in event of a fire precautions must be taken. With door retainers linked to your conventional fire system panel, they will automatically be released on fire alarm activation, helping to save lives through fire spread prevention.

Whether the setting is in industrial premises or commercial or public buildings, Eaton's heavy duty door retainers will hold a force of up to 40kg. With a manual release option and the ability to be powered through mains or DC, they are ideal for preserving safety in emergency situations but are flexible enough to suit the day ahead.
