A range of hold open electro-magnets are available which have either a plastic or metal housing and provide the perfect complement to a technically and aesthetically advanced range of fire and smoke check door products. Offering maximum reliability these 24V and 230V DC hold open electro-magnets are easy to install and give functional elegance.
The range also includes the Agrippa sound actuated fire door holder which is powered by two “C” cell batteries and completely wire-free. The product reacts to the specific sound of the building’s fire alarm. The magnetic fire door holder can be fitted as a safe and legal method of holding a fire door open to ease accessibility and increase ventilation. If the fire alarm sounds, the device will automatically close the fire door to protect the building and people in it, in the event of a fire. The devices will not hold the door open if the batteries run out of power.
