Casement window locking bar sensor

A method of providing a window status sensor system, in which a window includes a casement window locking assembly, the casement window locking assembly comprising:

• a locking handle;
• a housing;
• a locking bar;
• and
• a coupling member to transfer movement of the locking handle to the locking bar;
• wherein the locking handle is movable between a locked position and an unlocked position, the locking handle being arranged to be mounted to part of a casement window assembly comprising a window frame having a window sash movably mounted therein,
• the casement window locking assembly comprising a sensor system to indicate if the window sash is closed within the window frame and also if the locking handle is in the locked position, the sensor system comprising:
• a first sensor and a second sensor,
• the first sensor comprising a first handle component secured to the coupling member and a second handle component mounted within the housing,
• the second sensor comprising a first window component mounted in the housing and a second window component being arranged to be mounted on the window sash,
• in which rotational movement of the locking handle causes translational movement of the coupling member and the first handle component is mounted on a mounting member arranged to be removably secured to the coupling member,
• the method comprising using the first sensor to detect the locking handle being in the locked position and using the second sensor to detect the window sash being in the closed position.
