VENTILATING WINDOWS WITHOUT
FALSE ALARMS
Sentrol recommends two methods for opening windows for ventilation without
causing a false alarm.
First, a small dot, either adhesive or painted, can be added to both the window
frame and window jamb that marks the spot above which the window should not
be opened. The user simply aligns the halves of the dot as shown below.
Second, a window stop can be provided so that the window cannot pass the alarm
point in normal usage. Drill a hole in the jamb for the stop. Use a nail or small
dowel as the stop. The dowel or nail should protrude from the hole so it supports
the opened window, as shown below.
