The GV-EL202B is an electric bolt, featured with a stainless steel faceplate and a built-in voltage spike suppressor. It supports lock sensor and door status sensor functions. The fail-safe electric bolt locks the door when the power is applied, and unlocks the door when the power is removed. It can be applied to single-leaf or double-leaf doors.
The GV-EL124S is a fail-secure electric strike. But it is field convertible from fail secure to fail safe. It can be mounted either right or left reversibly on the doorjamb, providing remote release of a locked door.
