*****CM 5000D CURTAIN-MINDER INSTRUCTIONS*****
1- Unpack your CM 5000D Curtain-Minder. Remove the transformer and the winch kit.
2- The transformer mounts on a 7/8" knock out of a junction box, handy box, or breaker panel. It is
best to wire the primary wire leads of the transformer to a fan power supply circuit, preferably the
workhorse fan breaker.
3- Mount the CM 5000D Curtain-Minder on the wall so the white wires will reach the transformer.
Connect the white lamp cord from the 24 VAC terminals of the Curtain-Minder to the screw
terminals on the transformer. Apply power to the unit and see that the AC POWER light is on.
Disconnect the power and continue the installation.
4- You have two reliable choices for installing the Winch Kit(s). The parts are included for both.
(A) The DIRECT-CONNECT method (Page 7, Figure 1A), eliminates the loss of the braided
cord with the handle hook. The cord is tied above and to one side of the winch kit so the winch kit
can swing out of the way of the winch handle. To operate, the winch kit is closed so the hinge
meets the blue electro-magnet. The string loop (with the HANDLE HOOK) is draped over the
hinge. Make sure the loop drapes over the knuckle of the hinge and does not make contact with the
tilt screw. Now let the winch handle cradle in the handle hook. You may prefer to crimp the
handle hook to the winch handle to prevent it from getting lost.
(B) The ORIGINAL method (Page 7, Figure 1B) provides good holding power, especially when
curtain machines are used. Mount the winch kit on a mounting surface as near the winch handle as
possible, using the holes in the top of the plate. The hinge, when open, should point toward the
winch handle. Make sure the tilt screw is in enough for the hinge to contact the magnet. Remove
the handle hook from the short loop by cutting or untying the cord. Cut a piece of PVC pipe nearly
as long as the cord. Thread the looped end of the cord through the piece of PVC pipe. Refer to
Figure 1B. Drape the looped end of the braided cord over the hinge so that it rests at the knuckle of
the hinge. Keeping the cord as short as possible, tie the handle hook on the other end of the cord
and cradle the winch handle in the handle hook. Remove the ratchet on the winch! Now the winch
kit is carrying the weight of the winch handle. When you positively do not want to release the
winch handle, let the hinge hang down and connect the looped end of the cord to the tilt screw.
5- You should use 18-gauge two-conductor lamp cord to make all of your connections. Other wire
may not be as satisfactory in the long run.
6- There are six terminal blocks with four screw terminals each on the right side of the front door
for all of the wiring connections. The terminal blocks can be unplugged for easy access. The
second through the fifth terminal block is used to wire the winch kits. The fifth terminal block is
labeled Magnet 1 and the second terminal block is labeled Magnet 4. There is no particular order
for numbering the winch kits.
The CM 5000D will accommodate up to five winches. There is a small yellow screwdriver
included for making the connections. Please leave the screwdriver inside the Curtain-Minder!

(a) Wiring for ONE Winch Kit (Page 10, Figure 4) Extend the magnet wires on the Winch Kit to
the Curtain-Minder using 18-gauge lamp cord. Connect the other end of the lamp cord to the
bottom screw labeled Magnet 1 and the top screw labeled Magnet 4. The reed switch wires should
be wired to the Normally Closed circuit on an alarm such as our MARK 220.
(b) Series Wiring for TWO Winch Kits (Page 10, Figure 5) Extend the magnet wires on two
Winch Kits using 18-gauge lamp cord. Connect one wire from each Winch Kit together. The other
end connects to the bottom screw labeled Magnet 1 and the top screw labeled Magnet 4.
(c) Series Wiring for THREE Winch Kits (Page 11, Figure 6) Extend the magnet wires on three
Winch Kits using 18-gauge lamp cord. Connect one wire from each Winch Kit together. A wire
from the 1st Winch Kit connects to the bottom screw labeled Magnet 1 and a wire from the 3rd
Winch Kit connects to the top screw labeled Magnet 4.
(d) Series Wiring for FOUR Winch Kits (Page 11, Figure 7) Extend the magnet wires on four
Winch Kits using18-gauge lamp cord. Connect one wire from each Winch Kit together. A wire
from the 1st Winch Kit connects to the bottom screw labeled Magnet 1 and a wire from the 4th
Winch Kit connects to the top screw labeled Magnet 4.
NOTE: A warning label is included with each winch kit. For safety, attach it near the curtain
winch. Being near the winch can be very hazardous, so STAY CLEAR!
7- The CM 5000D has a relay with a dry contact that can be tied to your alarm to tell you when the
unit has detected low power. There are three terminals at the top of the board (see Figure 3) for this
output. The alarm can be wired Normally Open (NO) or Normally Closed (NC).
8- Remove the green paper from the double-sided tape in the back of the unit and set the battery on
the tape. Connect the 12-volt lead acid rechargeable battery to the RED and BLACK wires being
sure to observe polarity.
9- Close the unit, reconnect the power to the unit, set the desired time delay and you are ready to
connect the winch handles.
10- A very nice feature of the CM 5000D is that you can test the Curtain-Minder with a short time
delay. Set the timer knob to 1 and remove the power from the circuit being monitored. The Low
Power/Timing light should be blinking and the curtains should drop. After testing, be sure to set
the knob to your desired delay time and reconnect the winches.
NEW TO THE CM 5000D –
Please follow these suggested wiring instructions when you are using the WK 1510 winch kit for
“Automatic Tunnel Mode.” We recommend using 4-conductor 18-22 gauge wire.
(1T)- Open the unit and set the DIP switch for the number of winches you are using. The DIP
switch is located on the left hand side of the board. Push the switch or switches up for each winch
being used. The switches on the next page show the selection for 1, 2, 3 or 4 winches.

1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4
(2T)- If you use fewer than 4 winch kits, it is necessary to put a jumper between the two terminals
for each reed switch that is not used. You will need to cut a piece of scrap-stranded wire about 3
inches long and strip it on both ends. See the wiring diagrams on pages 11 and 12 for the correct
locations of the jumpers.
(A) Wiring ONE WK 1510 in “Automatic Tunnel Mode” (Page 12, Figure 8) Using the black
and white conductor of 4 conductor 18-22 gauge wire extend the reed switch wires. Connect the
other end of the black and white wires to the 2 screws labeled Reed Switch 1. Extend the magnet
wires with the red and green conductor. Connect the green wire to the bottom screw labeled
Magnet 1 and connect the red wire to the top screw labeled Magnet 4.
(B) Wiring TWO WK 1510 in “Automatic Tunnel Mode” (Page 12, Figure 9) Using the black
and white conductor of 4 conductor 18-22 gauge wire extend the reed switch wires. Connect the
other end of the black and white wires to the four screws labeled Reed Switch 1 and Reed Switch 2.
Extend the magnet wires with the red and green conductor. Connect the green wires to the bottom
screws labeled Magnet 1 and Magnet 2. Connect the red wire of the 1st to the bottom screw of
Magnet 1. Connect the red wire of the second magnet to the top screw of Magnet 4.
(C) Wiring THREE WK 1510 in “Automatic Tunnel Mode” (Page 13, Figure 10) Using the
black and white conductor of 4 conductor 18-22 gauge wire extend the reed switch wires. Connect
the other end of the black and white wires to the six screws labeled Reed Switch 1, Reed Switch 2
and Reed Switch 3. Extend the magnet wires with the red and green conductor. Connect the green
wires to the bottom screws labeled Magnet 1, Magnet 2 and Magnet 3. Connect the red wire of the
1st and 2nd magnet to the top screws labeled Magnet 1 and Magnet 2. Connect the red wire of the
3rd magnet to the top screw labeled Magnet 4.
(D) Wiring FOUR WK 1510 in “Automatic Tunnel Mode” (Page 13, Figure 11) Using the black
and white conductor of 4 conductor 18-22 gauge wire extend the reed switch wires. Connect the
other end of the black and white wires to the eight screws labeled Reed Switch 1, Reed Switch 2,
Reed Switch 3 and Reed Switch 4. Extend the magnet wires with the red and green conductor.
Connect the green wires to the bottom screws labeled Magnet 1, Magnet 2, Magnet 3 and Magnet
4. Connect the red wire of the 1st, 2nd and 3rd magnet to the top screw labeled Magnet 1, Magnet 2
and Magnet 3. Connect the red wire of the 4th magnet to the top screw labeled Magnet 4.
11- To test the battery set the timer knob to 2 minutes or more then push the battery test switch up
and hold for 15+ seconds. If the Timing light blinks and the magnets hold, the battery is good. If
the magnets drop, your battery needs to be replaced. Make sure you replace the battery with a
12-volt sealed lead acid rechargeable battery that is at least 2.5 amp hours.
12- An extra safety feature is also on the board. If for some reason, the curtains have not dropped
in the amount of time you have set on the CM 5000D, after 10 minutes the circuit dies and the
magnets release.

A CONFESSION
We at Pro-Tech, Inc. have done our best to build your Curtain-Minder free of defects.
However, we are human; therefore, your Curtain-Minder was subjected to human error. Please
test the Curtain-Minder thoroughly and frequently. We promise the Curtain-Minder will fail. We
hope it does not fail in your lifetime. When it fails, it will likely fail when you need it most. Please
remember that Terry Allen and Jim Sutton designed this product so anything is possible!
13- A back-up high temperature thermostat can release the curtains or windows. The best way is to
connect a Ther-Minder, by Pro-Tech, Inc. to the Curtain-Minder using the NC instructions in Fig.
2b on page 7. Another way to achieve this is to connect a cooling thermostat, NO contacts, which
can also be the Ther-Minder shown in Fig. 2a on page 7. When the low power light blinks, the
alarm relay energizes. If the alarm relay is wired to an alarm, you should be notified.
14- The CM 5000D Curtain-Minder is the most fail-safe Curtain Release device available. The
CM 5000D will release curtain winches upon power outages and low voltages. If the Curtain-
Minder releases the curtain winches upon low voltage, the LOW POWER light will be blinking or
on if, the unit has timed out.
You have made a wise purchase; however, the CM 5000D Curtain-Minder is only a management
tool and NOT an insurance policy. It does not replace the attendant or make a poor attendant a
good one. For MAXIMUM PROTECTION, make sure that:
(A) The ratchet is removed.
(B) The weight of the winch handle is sufficient to flip the hinge completely down.
(C) The curtains will fall when the winch handle is released.
NEED MORE STRENGTH? There are two ways:
(1) The Winch Kit has a yellow dot on the part of the magnet, which holds the hinge. This dot
reduces the holding power of the Winch Kit. You may remove this yellow dot with your fingers
and increase the strength. Please test the unit to see the Winch Kit(s) turn the winch loose, as you
would expect.
(2) For use with Curtain Machines to make the Curtain-Minder heavy duty (Double holding
power): See (Figure 3, page 8) and do the following:
(A) Open the door to the Curtain-Minder.
(B) Locate J4 to the left of the terminals for wiring Magnet 4. There is a "shorting jumper”
connecting the middle pin and the lower pin.
(C) Remove the "shorting jumper" and put the "shorting jumper" on the middle pin and the upper
pin.
Note:
We are asked occasionally if one transformer can operate both the Curtain-Minder and the Mark
220 Alarm. The answer is yes if you use the transformer that comes with the Mark 220 Alarm.
Both transformers have the same input and the same output. The Mark 220 has twice the
amperage, so it is bigger and heavier. The alarm transformer is rated at 40 VA while the Curtain-
Minder transformer is rated at 20 VA.
