Alarmed Window Bar (Fits Windows 30"-42")

Alarmed Window Bars will fit windows from 30” to 42” wide with no cutting required. If window is higher than 14”, two or more Window Bars may be used. They protect both sides of a sliding window even when open without triggering an alarm and can be connected to a 24 hour zone. When the bar is dislodged an alarm is activated. The Alarmed Window Bars are easy to remove during an emergency and will work with both hard wired or wireless systems. The bars are designed to fit the window one way and are difficult to be installed incorrectly. The reinforced extruded aluminum will not sag or flex in high temperatures. For windows smaller than 30”, the 5/8” bar may be cut off to fit. Make certain that you cut off the end without the magnet.

The various ways in which the GRI Window Bar may be mounted are: on the window frame, inside the window frame and on most angled window frames.

Installation Instructions

The Window Bars should be installed no more than 6 inches apart and no more than 6 inches from the top and bottom of the window frame. On a 14” high window, the bar should be vertically centered.

Test switch before installing by using a continuity tester or a similar device. With the leads of the switch connected to the tester, place a magnet next to switch. The contacts of the switch will open and close as the magnet is moved within range of the switch. Mount Window Bar into selected area of window, making certain it is spaced correctly as noted above. Place small end of bar into recessed area of switch. Remove backing from double stick tape on switch and install on window frame or jamb.

Note: Instructions should be given on removal of barrier bars to all residents of building where window bars are in use. The Window Bar is removed by grasping the ends of the bar and pushing them to the center and pulling the bar out of the window.
