What You Should Know Before Starting
Languages: This installation booklet is available in French and Spanish on our
web site at www.truth.com/technicalsupport.
Supply Voltage Note: The supply voltage range for the Sentry II power skylight
system is very flexible to accommodate supply voltages available from many
different countries. The input (supply) voltage range is 90 to 264 VAC at a
frequency range of 47 to 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 operating temperature range must be maintained
between 140º F (60º C) to -5º F (-20º C).
Single motor vs. multiple (synchronous) motor application: Most
applications of the Sentry II HS system will be a single motor on a single skylight.
However, the Sentry II HS motor system can be used in a number of different
applications depending on the size and weight of your skylight lid. The skylight
lid must weigh less than 160 lbs. (80 lbs. at the chain) for a single motor
installation. If your skylight lid is heavier than 160 lbs., multiple motors (up to 4)
can be used to lift a single skylight lid. The maximum skylight weight for 4
motors is 400lbs. This is called a synchronous motor application. Please refer to
page 29 for the details of this installation.
Multiple motors on separate skylights: There is a way of wiring several
motors on different skylights together so that they all will respond to one wall
switch or one HPI input. Please refer to page 28 for the details of this
installation.

Planning
Important: If you are not the homeowner, it is important to contact the
homeowner and discuss how they want to control a group of skylights. It may be
very difficult to change the installation to meet the homeowner’s desires once
installation is complete.
Please consider:
•In case of a power outage the Sentry II power skylight system does not
have manual override. If it is important to be able to close the skylights
without power, consider installing a battery back-up system.
•There are a number of other control options available:
oRemote Control Has Built-in Thermostat for those applications
where it is desirable to open and close skylights based on
temperature. Just set the temperature and place the remote in the
area where you want the temperature controlled. Every Sentry II
HS unit is remote control enabled.
oA Rain Sensor comes standard with each unit. If you choose to
install the rain sensor, each control unit needs a separate rain
sensor. Consult main wiring diagram for wiring requirements.
oPower mini blinds -The Sentry II control unit is capable of
controlling power mini blinds (supplied by others). See page 20 for
additional information. Consult main wiring diagram for wiring
requirements.
oSkylight position feedback -The Sentry II control unit is capable
of providing skylight position feedback (open or closed). See page
20 for additional information. Consult main wiring diagram for
wiring requirements.
oIntegrated control with other control systems - The Sentry II
power skylight system can be integrated with other automated
control systems. Some examples are home automation systems,
thermostats and security systems. See the HPI section on page 18
for additional information. Consult main wiring diagram for wiring
requirements if used.
•Plan your circuits based on 1 amp of power at 120 VAC per motor unit.
•The primary means of skylight control is the remote control. An optional
wall mounted switch panel is available if required.
oIf installing a wall mounted switch panel – See main wiring diagram
for wiring details. Plan your wiring routes carefully. Low voltage
wires must not be run parallel to high voltage wires.

Initialization
The power skylight system is now ready to be initialized. Initialization occurs
automatically when the motor unit receives its first “Open” command.
•Upon receiving an “Open” command for the very first time after original
power up, the unit will automatically run through an initialization cycle.
Initialization consists of one full open and closed cycle.
•The “Open” command can be given from any of three control devices:
oRemote Control (Note: The remote must first be
programmed – see step 11)
oWall switch
oHPI Input
•During initialization the LED on the motor cover (and on the switch face
plate if installed) will display a “Red” LED.
Note: This cycle is necessary for the unit to establish its operating
parameters which will be stored in permanent memory. Once
permanent memory is established it is unaffected by loss of power of
any duration.
11. Program Remote Control
If a remote control is part of the installation it should now be programmed to
the control unit. Refer to set-up instructions included with the remote control
for proper set-up.
Skip this step if the installation does not include a remote control.
Normal Operation
From the remote control:
To open the skylight:
•Select “Unit” number (or “all”) for the skylight you want to control.
•Press “Open” button.
Note: The full open position varies with operating hardware and
curb height of the skylight. The typical stop position is approx. 90%
of full open.
To close the skylight:
•Select “Unit” number (or “all”) for the skylight you want to control.
•Press “Close” button.
For an intermediate open position,
•Press the “opposite” function while the motor is running - the motor
will stop in that position.
Further information on using the remote control can be found in the
instructions packaged with the remote.

Status Light Indicator
During operation the status light located on the skylight motor cover
will be steady green to indicate normal operation. (See “Status
Codes” on page 25 for more information.)
From the optional wall switch control:
To open the skylight:
•Press skylight “Open” button.
Note: The full open position varies with operating hardware and
curb height of the skylight. The typical stop position is approx. 90%
of full open.
To close the skylight:
•Press skylight “Close” button.
For an intermediate open position,
•Press the “opposite” function while the motor is running - the motor
will stop in that position.
Status Light Indicator
During operation the status light located in the skylight motor and on
the switch face plate will be steady green to indicate normal operation.
(See “Status Codes” on page 25 for more information.)
Note: Any time there is a power outage, the skylights will automatically
close when power is restored. The system is programmed this way
because the system will not recognize any attempts to open or close
the skylight while the power is off including attempts by the rain sensor
(if installed) to close. Therefore, the safest position for the skylight to
be in when power is restored is closed. All controls will return to
normal function once power is restored.

Accessories
Battery Backup
Battery backup should be used to supply emergency power when operation
of the power skylight system must be maintained in the event of a power
outage. (Please note: A battery back-up is not required to provide memory
back-up for the Sentry II system.)
Truth recommends the use of a UPS (uninterruptible power supply) as a
battery backup. They are widely available through a variety of retail and
commercial outlets and are primarily used to supply emergency backup for
computer equipment. (Truth Hardware is not a supplier of battery back-up
systems.)
To determine the proper VA rating for a UPS, take 50 watts and multiply by
the number of skylights to be backed up by a given UPS. Below is a list of
the manufacturers who produce uninterruptible power supplies which Truth
Hardware has approved as compatible with our power skylight systems.

Wall Mounted Switch Panel (Optional)
An optional wall mounted switch panel can be ordered to control a skylight (or
skylights) from a wall mounted switch panel. The switch panel can be used in
conjunction with a remote control or by itself.
Installation – See installation instructions supplied with Switch Panel. For
multiple units the switch is connected to the Leader.
Important: It is not recommended to connect other input devices in place of
the membrane switches on the wall switch panel.
Helpful Hint: The cover plate is only available in one configuration and color.
The cover plate can however, be painted or wall paper can be applied to
change its appearance.
Rain Sensor (included)
The sensor will close the skylight when “beading” moisture is present on the
surface of the rain sensor grid. It will also cause the green LED on the motor unit
to blink (indicating moisture is present) while the skylight is closing. Once the
rain sensor grid is dry, normal operation will resume.
Warning: Do not install the rain sensor if the skylight is being controlled as a
smoke vent to vent smoke in case of a fire. The rain sensor overrides all other
inputs. (see HPI, page 19).
Note: Rain sensor installation is optional.
Installation of Rain Sensor
•Locate the desired mounting location for the rain sensor. It should be
as horizontal as possible to accumulate rain.
•Route rain sensor wires into control unit housing.
Note: Do not route rain sensor wire through the operator chain port,
damage to rain sensor wire will be a likely result.

Interior Mounting Exterior Mounting
Install Rain Sensor Grid
•Connect the rain sensor wires to the Grey & Green terminals on
Port “5”.
Rain Sensor Guidelines:
•Install the sensor with "grid" exposed to outside elements where the rain
has a clear, unobstructed path to the rain sensor. Consider prevailing
winds.
•If the desired location of the rain sensor exceeds the wire length supplied,
use 22 AWG - 2 conductor shielded, twisted pair 50 ft (15m) maximum
length.
Important: Connect shield to earth ground to reduce interference from
lightning and other electrical devices.
•The sensor can be installed outside (maximum sensitivity) or inside vent
edge (minimum maintenance)
•Recommended maintenance: Regular cleaning of sensor panel with a mild
cleaning agent is recommended. Dirt or debris can cause the vent to stay
closed even when rain is not present.
Note:
•There is a 10 second delay from the time the rain sensor senses moisture
to the time the skylight actually starts to close.
•When the skylight is closed because of rain, it can be forced to open by
holding down the “Open” button even when the sensor is “wet”, however,
the skylight will immediately re-close once the open button is released.

High Priority Inputs (HPI)
The control unit located at the skylight includes inputs to allow skylight control
from other devices such as thermostats, home automation systems, security
systems, smoke evacuation systems, etc. These inputs are called High Priority
Inputs (HPI). There is an input for “Open” and an input for “Close”. The inputs
are designed to be controlled with low voltage dry contacts (relay).
Note: See main wiring diagram on page 7 for proper hook-up.
Input Function - HPI Close
1. When connected by a continuous contact closure, the skylight will
fully close. All other input devices (except for HPI Open) will be
“locked-out” until the contact closure is re-opened
2. When connected by momentary contact closure, the skylight will
close. There will be a minimum delay of 3 seconds before system
will react.
•A contact closure of 3 seconds is needed to activate a “close”
command.
Input Function - HPI Open
1. When connected by a continuous contact closure, the skylight will
fully open. All other input devices will be “locked-out” until the
contact closure is re-opened. There will be a minimum delay of 3
seconds before system will react.
2. When connected by momentary contact closure, the skylight will
open. There will be a minimum delay of 3 seconds before system
will react.
•A contact closure of 3 seconds is needed to activate an “open”
command.
Intermediate Open position
The skylight can be stopped in an intermediate position with a ½
second momentary contact closure across the contacts for the
direction opposite the skylight travel. For instance, if the skylight is
opening, a momentary contact closure of ½ second across the HPI
“Close” contacts will stop the skylight.
Wiring
18-2 twisted pair is recommended up to 150 feet maximum.
Control Switch Options
•Some home automation companies offer control switches that can
be used to control the Sentry II HS control unit through the HPI
inputs. Consult the Truth Hardware web site for more information.

Helpful Information
•Voltage supplied by HPI input is: 12 VDC @ 5mA.
•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.
System Status Feedback
The Sentry II control unit is capable of providing feedback regarding whether
the skylight is closed or not closed. (System feedback is not capable of
providing true skylight position.)
Note: See main wiring diagram on page 7 for proper hook-up.
Status output function:
The status output functions as a relay. When the output is closed
(relay contacts closed), the skylight is fully closed. When the output is
open (relay contacts open), the skylight is not fully closed.
Feedback output (contact closure) maximum ratings:
Rated Load: 0.50 A at 125VAC, 1 A at 24VDC
Minimum Load: 1mA, 5VDC
Max. operating voltage: 125 VAC, 60 VDC
Max. operating current: 1A
Max. switching capacity: 62.50 VA, 30W
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.
