Supply Voltage Note: The supply voltage range for the Sentry II power window
system is very flexible to accommodate supply voltages available from many
different countries. The input (supply) voltage range is 90 to 264VAC at a
frequency range of 47to 440 Hz. For practical purposes, the supply voltage
referenced in this document is 120 volts at 60 Hz commonly used in the United
States.
Operating Environment: The control unit must be located in a dry environment
which includes protection from condensation. The operating temperature range
must be maintained between 140ºF (60ºC) to -5ºF (-20ºC).
Be sure the motor system will fit in your application: The Sentry power
window system is intended to fit onto casement, awning and skylight hardware
manufactured by Truth Hardware only. In many cases you will be able to identify
our hardware by our logo ( ) somewhere on the hardware. When in doubt, the
best way to tell is if the spline adaptor fits onto the operator stem in place of the
crank handle – see Motor Installation step 2 .
The Sentry II power window will not work in the following applications:
xFitted to any type of jalousie window
xFitted to any type of door
xFitted to any type of cable controlled window system -Such as those

Any use of the Sentry II power window system not approved by Truth
Hardware is at the user’s own risk.
Be sure the motor system is compatible with your application: It is
important to understand that the design parameters of the Sentry II power
window system are predicated on a properly functioning manual window system.
This includes the rotary operators and hinges installed on the window. It is the
responsibility of the window manufacturer and/or the window specifier to insure
the window size and weight fall within the specifications of the manual hardware
system installed on the window. If the window size and/or weight fall outside of
the hardware specifications, the motor system may not function properly. If the
window carries an AAMA (American Architectural Manufacturers Association)
label chances are the window system meets all hardware requirements.
However, if the window does not carry an AAMA label you may want to contact
the window manufacturer to verify the windows have been manufacturer within
the hardware manufacturer’s specifications -especially if the window size is
unusually large and/or of unusual proportions.
