Fenestration unit monitoring devices and methods
First Claim
1. A fenestration unit monitoring device configured for retrofitting an existing fenestration unit lock assembly, the device comprising:
- a monitor housing configured for mounting on a surface of a frame member of a first panel after a fenestration unit lock assembly is mounted on the surface of the frame member, monitor housing comprising;
a lock cavity defined between the monitor housing and the surface of the frame member when the monitor housing is mounted on the surface of the frame member, wherein a portion of the fenestration unit lock assembly is located in the lock cavity formed between the monitor housing and the surface of the frame member when the monitor housing is mounted on the surface of the frame member;
optionally, a monitor fastener opening configured to align with a lock assembly fastener opening of the fenestration unit lock assembly when the monitor housing is mounted on the surface of the frame member with the portion of a fenestration unit lock assembly located in the lock cavity, wherein a single fastener can extend through both the monitor fastener opening and the lock assembly fastener opening to secure both the monitor housing and the fenestration unit lock assembly to the frame member of the first panel;
a controller cavity located between the monitor housing and the surface of the frame member when the monitor housing is mounted on the surface of the frame member;
a lock arm sensor operably attached to monitor housing, the lock arm sensor positioned to detect the presence of a lock arm of the fenestration unit lock assembly when the lock arm is in a locked position associated with a locked state of the fenestration unit lock assembly;
a panel position sensor located in the controller cavity of the monitor housing, the panel position sensor configured to detect a position of a second panel of the fenestration unit relative to the first panel;
a controller located in the controller cavity of the monitor housing, wherein the controller is operably connected to the lock arm sensor and the panel position sensor, and further wherein the controller is configured to;
receive a lock signal from the lock arm sensor when the lock arm of the fenestration unit lock assembly is in the locked position associated with the locked state of the fenestration unit lock assembly;
receive a panel position signal from the panel position sensor when the panel position sensor detects presence of the second panel; and
provide an indication of a status of one or both of the lock signal and the panel position signal.

Abstract
Fenestration unit monitoring devices described herein are configured to retrofit an existing fenestration unit lock assembly to incorporate components that are capable of monitoring the locked or unlocked status of the existing fenestration unit lock assembly and/or the panel position status of a movable panel of the fenestration unit. The fenestration unit monitoring devices include a monitor housing configured for mounting on the surface of a frame member on which a fenestration unit lock assembly is already mounted. The monitor housing of the fenestration unit monitoring device includes a lock cavity such that a portion of the fenestration unit lock assembly is located in the lock cavity formed between the monitor housing and the surface of a frame member to which the monitor housing is mounted.

12. A method of installing a fenestration unit monitoring device on a fenestration unit that includes an existing fenestration unit lock assembly, the method comprising:
-
optionally removing a fastener attaching the fenestration unit lock assembly to a surface of a frame member of a first panel of the fenestration unit; positioning a monitor housing on the surface of the frame member of the first panel (after optionally removing the fastener) such that a portion of the fenestration unit lock assembly is located within a lock cavity of the monitor housing, wherein the lock cavity is defined between the monitor housing and the surface of the frame member when the monitor housing is mounted on the surface of the frame member; and securing the monitor housing and the fenestration unit lock assembly to the frame member (optionally using a fastener extending through a monitor fastener opening in the monitor housing that is aligned with a fastener opening of the fenestration unit lock assembly) after positioning the monitor housing on the surface of the frame member of the first panel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
