1. An anti-intrusion window comprising:
- a. a frame assembly adapted to be attached to a building structure;
b. a first sash assembly supported by the frame assembly for movement with respect to said frame assembly along a path of travel from a closed position;
c. a second sash assembly supported by said frame assembly;
d. a position indicator supported by one of said sash assemblies;
e. a sensor supported by the other of said sash assemblies, said sensor and said position indicator moving with respect to one another when said first sash assembly is moved along said path of travel relative to said second sash assembly, said sensor effective to detect the presence of said position indicator near said sensor; and
,f. an alarm system for triggering an alarm in response to the momentary presence of said position indicator near said sensor;
g. said position indicator and said sensor supported at locations spaced apart along said path of travel when said first and second sash assemblies are positioned at respective closed positions so that said alarm system is ineffective to trigger an alarm until the window is opened a predetermined amount.

Abstract
An anti-intrusion window is disclosed comprising a window frame assembly adapted to be attached to a building structure, first and second sash assemblies supported by the frame assembly and relatively movable with respect to each other, a position indicator supported by one sash, a sensor supported by the other sash and an alarm signal generator activated whenever the position indicator and the sensor are at least momentarily adjacent each other. Multiple windows are coupled to a second alarm signal generator which produces an audible alarm when the first alarm signal generator transmits an alarm signal. The sashes may be moved into cleaning positions without triggering an alarm.

11. An anti-intrusion window comprising:
-
a. a frame assembly adapted to be attached to a building structure; b. a first sash assembly supported by the frame assembly for movement with respect to said frame assembly along a path of travel from a closed position; c. a second sash assembly supported by said frame assembly for movement with respect to said frame assembly along a second path of travel adjacent and parallel to said first path of travel, said second sash assembly movable from a closed position; d. a position indicator supported by one of said sash assemblies; e. a sensor supported by the other of said sash assemblies so that said sensor and said position indicator move with respect to one another when either of said sash assemblies is moved along its respective path of travel, said sensor effective to detect the presence of said position indicator near said sensor; and
,f. an alarm system for triggering an alarm in response to the momentary presence of said position indicator near said sensor; g. said position indicator and said sensor supported at locations spaced substantially apart in the direction of said paths of travel when said sash assemblies are positioned at their respective closed positions so that said sash assemblies may be moved relative to each other from their closed positions without triggering an alarm. - View Dependent Claims (12, 13, 14, 15, 16)
