Operation

Covers automatically spring open to approximately 80 degrees in the event of fire, being actuated by the parting of a single UL-listed fusible link, or manually opened by actuating interior or exterior release. Once covers are fully opened, gas springs will lock to prevent the covers from prematurely closing. The locks can be opened with an external cable routing to allow the covers to be closed
