The wireless Freedor product is installed at the top of a fire door and allows them to be kept open safely, and it automatically releases when the fire alarm sounds.
Dorgard meanwhile provides the same service but is installed at the bottom of the fire door.
According to a press release the Freedor and Dorgard systems have been installed onto staff kitchen doors and fire door access routes throughout City library buildings.
The statement said that the council is “very pleased with their performance, as they allow high-use fire doors to be kept open with the reassurance of knowing that the doors will close automatically in the event of a fire emergency.”
Freedor and Dorgard are both produced by Fireco.
