When multiple input sources are used to control a given set of
skylights consult the Input Command Priority Table on the Truth
Hardware Web site (truth.com) to insure you receive the proper
skylight response to multiple input command sources.

Power Blind Control
The Sentry II control unit is capable of controlling 24 VDC blinds or shades.
Truth Hardware does not supply power blinds or shades. We only supply a
convenient control method with the same Sentry II control system. Therefore, it
is very important that a blind system be chosen that is compatible with the Sentry
II control system. Please use the following electrical specifications when
selecting a power blind or shade:
•
Operating Voltage: 24 VDC
•
Maximum current draw: 1 amp (at 24 VDC)
•
Power blind system must be range protected with internal limit
switches.
Note: Truth Hardware does not supply the installation instructions for the
installation of the motorized blinds themselves. Please consult instructions
supplied with the blinds for installation. If it is installed on a Synchronous system
the blind would be connected to the Leader only.
