NOTE: Do not kink or crush pneumatic tubing.
The supervised edge system consists of two distinct components,
the transmitter and the receiver. The receiver, which is connected
to the operator, behaves like a normally open safety edge. The
receiver requires a power and ground connection (DC) or an
AC connection. The transmitter is connected to the safety edge
and uses an internal 3V lithium battery for power. Battery life
is estimated at one year, however, conditions may vary. For
convenience, a low battery warning tone wil sound to indicate that
replacement is required (See diagnostics). The system requires
several considerations when deciding upon where to locate the
units on the door.
NOTE: Refer to door system illustration on page 3 for basic door
setup. Location and configuration may differ from illustration.
1. Both units must be located on the same side of the door. There
must be a clear line of sight between the units throughout
door/grill range of travel (Refer to page 3, figure 4).
2. The transmitter must always remain below the receiver
throughout the door’s range of travel.
3. The receiver placement must be within 2' of transmitter
centerline (Refer to page 3, figure 5).

NOTE: The receiver may be mounted to the lip of the door hood,
either outside or inside, depending on door design and clearance
within the hood when the door is in the fully open position. The
receiver also may be mounted on the door’s end bracket. Optimal
mounting position for the receiver will vary depending on the door.

7. Insert resistor assembly into other end of edge. Insert
wire connector pins into the middle of the copper strands
to ensure a good connection. Insert one pin into the
upper copper strand and one pin into the lower
copper strand.
8. Carefully apply a thin, even layer of adhesive to the ridge
inside the end cap. Do not to get any adhesive on the
sealing lip or on the cable. Attach end cap to the profile
from the foot side. Line up the corners so the end cap is
straight. Immediately press firmly on the cap for
approximately 10 seconds.
9. Roll back the sealing lip on the end cap and apply a thin,
even layer of adhesive to the surface. Unroll sealing lip
and press firmly on the entire adhesive joint for
approximately 10 seconds.
10. Carefully pull cable to one side and apply adhesive to
bushing allowing the adhesive to run inside the sleeve
around the cable. Apply a thin layer of adhesive to the
edge of the cable bushing to seal.
1. Using scissors or a sharp razor to cut edge to length adding
a total of 1" for end caps.
2. Carefully trim foot by 1/2" on each end of the edge. Make
certain no damage is done to the profile when making the
vertical cut. Any remains of the foot will be removed later
with sand paper.
3. Before sanding surface, cut protruding copper wire.
4. Using sand paper, smooth all cut surfaces even and mat,
making sure you do not round edges, on each end of edge,
including the area where footing was removed.
5. Open one of the end caps using a hole punch or any other
sharp object. Remove any remaining material. Feed
connecting cable through the hole.
6. Insert wire connector pins into the middle of the copper
strands to ensure a good connection. Insert one pin into the
upper copper strand and one pin into the lower copper
strand.
11. Slide edge into door astragal.

The supervised edge system is capable of communicating in either of two channels, A or B. Each unit is set to the default communication
channel A from the factory. Under most conditions the factory setting will not have to be changed. When two systems are used in close
proximity (less than 6 feet), one system should be set to channel B.
To select Channel B the rear covers of both units must be removed and the jumpers marked in the following illustration must be placed
over both pins. To select Channel A the jumper should be placed over one of the pins securing it for storage.

The supervised edge system is designed to provide status information to the installer or maintenance personnel in order to assist in
troubleshooting. There are three indicators in the receiver unit to observe: the green “heartbeat” LED, the red “fault” LED, and an
integral trouble sounder.
CONDITION SOLUTION
• Red LED on
• 3 beeps repeated every 2 seconds
• Green LED does not flash
Transmission path failure. Make sure there is a direct line of sight
between transmitter and receiver. Transmitter LED or receiver
may be dirty.
OR
The battery was not properly inserted into the transmitter unit.
Open the transmitter unit and make sure the battery is inserted
with the correct polarity.
• Red LED on
• 3 beeps repeated every 2 seconds
• Green LED flashes about every second
One unit is set to channel A while the other is set to channel
B. Open one of the units and change the channel jumper as
described in channel election section.
(ELECTRIC EDGE ONLY)
• Red LED on
• 3 beeps repeated every 2 seconds
• Green LED flashes about every second
Safety edge open fault. Open the transmitter unit and make sure
connections are tight.
The safety edge is open or does not have an 8.2k Ohm resistor
embedded. Use a multimeter to check the resistance on the edge,
it should be between 7.5k Ohms and 15k Ohms.
• Red LED on
• 3 beeps repeated every 2 seconds
• Green LED flashes about every second
The door/grill is closed on an uneven surface. This is a normal
condition if continuously depressed.
(ELECTRIC EDGE ONLY)
Safety edge is shorted or partially shorted. Check the edge
connections in transmitter, and then measure the safety edge
resistance. Correct tolerance is 7.5k Ohms to 15k Ohms. Replace
edge if out of tolerance.
• Red LED Off
• Sounder sounds 2 beeps every ten seconds
• Green LED flashes about every second
Low battery indication. Replace the battery in the transmitter unit
with a 3V Lithium battery.
IMPORTANT - Test system thoroughly before the door is put
into normal operation. Stand clear of the door until it is fully
tested. If any failure occurs during the test procedure, turn all
power to the operator off and follow the suggestions in the
Diagnostics section of this guide.
1. Turn power on to the operator.
2. The system should remain quiet and the green LED should
flash briefly once a second.
3. Cover the protruding LED on the transmitter unit. The red LED
on the receiver unit should come on and be accompanied by a
3-beep warning from the trouble sounder every 2 seconds.
Uncover the LED.
4. Partially open the door. Squeeze the safety edge. The red LED
on the receiver unit should come on and be accompanied by a
3-second continuous warning from the trouble sounder.
Release the safety edge.
5. Begin closing the door. Being careful to stand clear of the door,
squeeze the safety edge. The door should stop its downward
motion and begin to open.
6. Allow door to open completely. The system should remain quiet
and the green LED should flash briefly once a second. Both
units should have an unimpeded path throughout the range of
motion of the door. Strain relief should be used on both cables
as well as additional cable ties as necessary.
