BLACK DEVICES Garage Guardian User manual

Black Devices LLC’s (blackdevices.com) Garage Guardian closes
the garage if you forget. It uses a programmable timer and
“eyes” to see and time how long your door is left open, and
closes it after the time expires. Features include:
Audio warning beeps 16 times prior to closing
Programmable timer at minute intervals (can be disabled)
Programmable via your existing wall button
Battery saver technology (with low battery warning)
Detect Open/Detect Closed modes
Retains programming across battery changes
This device operates in two modes. Detect-Open mode and
Detect-Closed mode. Most installations will operate under
Detect-Open mode. You should have received your device
already in Detect-Open mode. If you need to change the mode
of operation, see “Changing Detect-Open/Closed Modes” under
the OPERATION section of this manual .
1. Pull lid off and install 2 AAA batteries. Replace lid.
2. Select an installation location:
a) Use your garage door opener to fully open door. With the
door open, select a location to mount the device with the
“eyes” of the device close to (1” to 2”) and facing the garage
door/hardware. Ensure the device is able to “see” the door
open by holding the device in position and watching for a
flashing LED. After 3 consecutive flashes, the device beeps 4
times to confirm that it sees the door open. The LED only
flashes when something is immediately in front of it. The
part it sees should only be there with the door open. Sticking
tape (included) on the door/hardware may help.
b) Ensure the surface of the rail is clean prior to applying the
Velcro strip. Secure the device at the location by applying
the supplied Velcro strips on both the device and on the rail.
Note: Recommended placement is underneath the central
chain guide rail; between the top of the garage door and the
garage door opener with the “eyes” of the device pointing
toward the emergency release hardware (shown in the
figure above). Do not unplug the opener during installation.
3. Connect the wires from the device to the opener:
a) Be prepared for opener to operate unexpectedly! First,
locate terminals on the garage-door-opener. You may have
to remove a cover to access the terminals. Refer to the
garage door opener manual to determine where the wall
button terminals are located. Garage Guardian connects to
the same opener terminals that the wall button connects to.
b) Connect the black wire to the common/ground terminal on
the opener (typically labeled with a white terminal or a “2”).
c) The red wire shares the terminal with the other wire in the
pair of wires leading from the wall button to the opener
(typically labeled with a red terminal or a “1”).
Note: If the wires are connected in reverse, the device’s red LED
will illuminate and the device may start beeping as long as the
wires remain connected. The garage opener may also operate!
That’s ok, simply reverse the wires to correct the polarity.
4. Program the device for the desired amount of time
and verify door closes after set time (see OPERATION).
Note: Changing the operation of the device is done with the
button on the device. It can also be done with your wall button if
the device has been properly installed and connected to your
garage door opener. (The opener can make noise if you use the
wall button. Try pushing it twice—the second push may stop it).

terminals as the wall button.

INSTALLATION
WARNING
FOR YOUR SAFETY –This product operates your door
autonomously. Before installing this product, ensure that
your garage door is equipped with an external entrapment
protection device, such as an "electric eye" which "sees" an
object obstructing the door without having actual contact
with the object. Do NOT install this product if your garage
door is not equipped with the auto reverse mechanism. To
prevent possible SERIOUS INJURY or DEATH, REPLACE YOUR
GARAGE OPENER IF IT IS NOT EQUIPPED WITH THE AUTO-
REVERSE MECHANISM.

INTRODUCTION
INSTALLATION (Continued)

Programming the Timer
To change the time, hold the button down for one second (until
you hear a beep). You are now in programming mode. Any
subsequent beep represents an additional minute the door is to
remain open.
For example, to program the device for 10 minutes:
1) Hold the button down for one second until you hear a beep.
2) Continue holding down the button until you count 10 more
beeps (1 beep for each minute).
3) Release the button. The device will play a tune representing
that it has just been programmed and is now enabled.
Note: Programming the timer automatically enables the device.
Note: Low battery warning is a quick 3-beep chirp.
Disabling/Enabling the Timer
Disabling the timer is useful if you want the door to remain open
indefinitely. It is easy to disable the timer and enable it again. To
toggle between enabled and disabled:
1) Hold the button down until you hear a single beep.
2) Release the button.
3) Listen for the tune being played.
Device Enabled: A scale increasing in pitch played, first
slowly and then fast.
Device Disabled: A scale in decreasing pitch played at a fast
rate, followed by the same scale played at a slower rate.
Note: If you hold the button down too long and hear a second (or
more) beeps, you are programming the timer delay (see
Programming the Timer). Make sure you set the desired delay.
Changing Detect-Open/Detect Closed Modes
Garage Guardian was designed primarily for garage door openers
where the door is closest to the opener when the door is fully
open (common to those found in the USA). However, it can be
used in many other types of door/gate/garage applications.
In some of these other configurations, the door/gate is closest to
the opener when the door is closed. Installing the device where
it would instead “see” the door/gate only when it is closed
(rather than open) is more convenient. This mode must also be
used for outdoor installations where thick fog may be present.
In order to support such an installation location, the device
needs to have its mode of operation changed (from “Detect
Open”, to “Detect Closed”).
To change the “Detect-Open/Detect Closed”:
1) Remove the lid. (It just pulls off.)
2) Touch the black wire to (only) the silver
colored pad shown.
3) Listen for the response:
1 Beep: The device is in Detect-Open
mode
2 Beeps: The device is in Detect-Closed
mode
4) Reattach the lid.
To prevent possible SERIOUS INJURY or DEATH, operate the door
ONLY under supervision. Do not allow any objects or persons to
cross or obstruct the path of travel of the door in motion.
