SECURITRON SERIES DSB DUAL SENSE BAR
INSTALLATION AND OPERATION INSTRUCTIONS
1. INTRODUCTION
The Securitron Dual Sense Bar (Model DSB) is an exit device intended for use on magnetically
locked, non-fire rated doors only. The bar will operate via mechanical movement (push) to
provide a primary egress function that does not require human touch in addition to function by
touch sense. The mechanical function has been included to simplify use and ease exit for
personnel with prosthetics or those who may otherwise have their hands occupied (e.g. carrying
boxes, manipulating carts, maneuvering wheelchairs, etc.). The assembly consists of an
aluminum bar available in lengths to fit standard U.S. door openings: (36", 42", and 48"). The
end mounts provide the mounting platform for the bar and house the electronic PC boards and
mechanical switching mechanisms within the bar.

6. INSTALLATION INSTRUCTIONS
AS THE DSB IS NORMALLY USED TO ALLOW EGRESS ON AN ELECTRICALLY SECURED
DOOR, ENSURE THAT ALL APPLICABLE BUILDING AND FIRE CODES ARE BEING
FOLLOWED. VERIFY INSTALLATION WITH LOCAL BUILDING AND/OR FIRE
PREVENTION CODES AND REGULATIONS.
THE DUAL SENSE BAR MAY NOT BE USED ON A FIRE RATED DOOR THAT REQUIRES A
FIRE RATED LATCH! THE DSB HAS NO LATCH. IN SOME INSTANCES HOWEVER, FIRE
DOORS ARE ALLOWED ON OPENINGS WHERE A FIRE RATED BARRIER IS NOT
REQUIRED. USE OF THE DSB SHOULD ALWAYS BE VERIFIED AND APPROVED
THROUGH LOCAL BUILDING CODE AND/OR FIRE PREVENTION DEPARTMENTS.
6.1. BAR POSITIONING AND MOUNTING HOLE MARKING
Using a #1 Phillips screwdriver, remove the screws and the end caps from both ends of the bar.
Verify that the bar is the correct length for the door. If it appears that the bar is longer than it
should be for the door, see Section 6.6 for cutting instructions. Take note of which end has the
main (touch sense) PC board in it, this end has a ring terminal connecting the PCB to the bar
profile. This is the end that should be mounted on the hinge side for the most convenient wire
exit from the door.
The DSB, as shipped from the factory, is assembled with shipping clips at each end that
temporarily hold the bar together while positioning and mounting the bar to the door (see
Figure 2).
FOR EASE OF INSTALLATION, DO NOT REMOVE THE SHIPPING CLIPS UNTIL AFTER THE
BAR HAS BEEN MOUNTED.
Figure 2
For best results, the assembled DSB itself may be used as a template to locate and mark the
mounting holes. When positioning the bar for marking the holes, ensure the following:
The bar is positioned at the correct height from the floor (see Figure 3).
Generally, US Building Codes require that the bar be located between 30 inches [762mm] and
44 inches [1118mm] from the bottom of the door.

PN# 500-22700
Page 3 Rev. F, 03/11
The bar is level.
The bar is centered on the door (left to right) between the door frame stops.
By using the assembled bar as a template, the correct separation between the mounting holes
will automatically be maintained. After marking the hole locations, verify that the centers of the
holes are at the required distance as shown in Figure 4.
Figure 3
Figure 4

PN# 500-22700
Page 4 Rev. F, 03/11
6.2. HOLLOW METAL DOOR PREPARATION
The bar should be mounted to the door using the blind nuts and screws provided as shown in
Figure 6. Use the following step-by-step instructions and Figure 5 for the installation of the
blind nuts:
a. Drill the four (4) 3/8” [9.5mm] diameter holes through the interior (mounting) surface of the
door at the previously marked hole locations. DO NOT drill completely through the door.
b. Insert one blind nut assembled to the installation tool into a mounting hole.
c. While holding the collapsing nut of the tool with a 1/2” box-end wrench, turn the socket head
cap screw using a 3/16” (or 5mm) hex wrench. Note: Maintain firm pressure toward the
mounting surface while collapsing the nut.
d. Once the blind nut is adequately collapsed, remove the tool from the installed nut by backing
the cap screw out of the blind nut.
e. Install all blind nuts by using the collapsing tool and repeating the previous steps.
f. After all blind nuts are installed, hold the bar in place over the blind nuts and secure into
place with the *plastic washers and mounting screws provided.
*THE PLASTIC WASHERS MUST BE INSTALLED UNDER THE SCREW HEADS FOR THE
DSB TO FUNCTION PROPERLY. ALSO ENSURE THAT THERE IS 1/32” CLEARANCE
BETWEEN EACH BAR END CAP AND THE INNER FLANGE OF THE BASE MOUNT BEFORE
FINAL TIGHTENING OF THE MOUNTING SCREWS.
Figure 5
6.3. SOLID WOOD DOOR PREPARATION:
The bar may be mounted using wood screws (not furnished). Four (4) #14 wood (or SMS)
screws with a hex head are recommended (see Figure 6).
Figure 6

PN# 500-22700
Page 5 Rev. F, 03/11
6.4. BOLT THROUGH DOOR PREPARATION:
For through-bolt mounting on various door types a DSB-TDM kit will be required (see Figure 7).
This product accessory is furnished separately and can be ordered from the factory at no charge.
This configuration may be used on solid wood doors, hollow or solid metal doors, or chalk filled
*fire doors. Please follow instructions included with the DSB-TDM kit for proper installation.
*THE DUAL SENSE BAR MAY NOT BE USED ON A FIRE RATED DOOR THAT REQUIRES A
FIRE RATED LATCH! THE DSB HAS NO LATCH. IN SOME INSTANCES HOWEVER, FIRE
DOORS ARE ALLOWED ON OPENINGS WHERE A FIRE RATED BARRIER IS NOT
REQUIRED. USE OF THE DSB SHOULD ALWAYS BE VERIFIED AND APPROVED
THROUGH LOCAL BUILDING CODE AND/OR FIRE PREVENTION DEPARTMENTS.
Figure 7
6.5. WIRE ACCESS HOLES
The DSB connects to a power source and access control systems via either a 16-foot 6-
conductor traditional wiring cable assembly (included with the standard DSB series), or an 8-
conductor ElectroLynx connector “pigtail” harness (included with the ELDSB series).
All DSB/ELDSB installations require that an 11/16” [17.5mm] diameter wire way hole be located
in the hinge side of the door at the position shown (see Figure 4). This hole allows either the
traditional cable with connector or the ElectroLynx wiring harness connectors to be pulled into
the door.
DSB – Traditional Wiring:
Wire routing from a hollow door implementing the traditional wiring method may be achieved
using a door cord. The TSB-C (included with the standard DSB) may be mounted toward the top
of the door between the door and frame, or mounted directly between the bar end mount and
frame (see Appendix B). Other commercially available electrical transfer hinges or pivots (such
as Securitron’s EPT or EPTL Electric Power Transfer) may also be used to route the wiring from
the door to the frame in a concealed manner. The following step-by-step instructions may be
used for the installation of the armored door cord between the door and frame:
a. Drill a 3/8” [9.5mm] diameter hole in the door and frame (hinge side) as shown in Figure 8.
b. Insert one (1) door cord insert into each end of the flexible cord conduit.
c. Run electrical wiring as required through the flexible cord conduit (with inserts) and the holes
in the door and frame.
d. Position the door cord caps to completely cover each 3/8” [9.5mm] diameter hole and use
the cap mounting holes as a template to mark and then drill two (2) 1/8” [3.2mm] pilot holes
for mounting.

PN# 500-22700
Page 6 Rev. F, 03/11
e. Insert each end of the (spiral) conduit into the recess of each of the cord caps and mount
each cap to the door and frame using a Phillips screwdriver and two (2) #6 X 3/4” long pan
head screws provided.
Figure 8
IT IS SUGGESTED THAT WIRE ROUTING FROM A SOLID DOOR USING THE
TRADITIONAL WIRING METHOD BE DONE USING AN ELECTRICAL TRANSFER HINGE OR
PIVOT (EPT OR EPTL) WHICH WILL SERVE TO ROUTE THE WIRING FROM THE DOOR TO
THE FRAME IN A CONCEALED MANNER.
ELDSB - ElectroLynx Wiring:
The ElectroLynx connection is the simplest method of transferring power and signal from the
device/door to the frame. Securitron’s EL-EPT or EL-EPTL are designed specifically for this
purpose.
IN ALL CASES THE BAR SHOULD BE MOUNTED SO THAT THE END MOUNT WHICH
HOUSES THE MAIN (TOUCH SENSE) PC BOARD IS ON THE HINGED SIDE OF THE DOOR.
DO NOT PULL OR RUN ANY CABLING OR WIRING THROUGH THE BAR, THIS CAN
POTENTIALLY CAUSE ELECTRICAL INTERFERENCE WITH THE TOUCH SENSE CIRCUIT
AND MAY BLOCK THE MECHANICAL MOTION OF THE BAR.
6.6. CUTTING THE BAR
If it is necessary to shorten the bar to achieve proper installation, the bar can be cut in the field.
The bar should always be cut from the end which houses the main (touch sense) PC board. To
do this the end mounts must be completely removed from the ends of the bar assembly. The
following step-by-step instructions may be used for shortening the DSB:
To determine the cut-to length you may use two measurements; to fit the existing opening or to
replace an existing Securitron TSB-3 using the same mount holes. If the TSB-3 length was not
altered from the factory your new DSB will fit into the same mounting holes and hardware.
1. If the bar does not fit the existing holes, measure the center-to-center spacing of
the existing holes. Subtract 2-5/8” [66.7mm] from that number and that is the
length the new bar must be cut to.
2. If the bar does not fit the existing door opening, measure the opening and subtract
4-5/8” [117.5mm] from that number. This is the length that the bar must be cut
to. This will provide the minimum recommended clearance of 1/2” [12.7mm] from
each end of the bar to the frame.
a. If not already done, remove the end mount caps from the end mounts using a screwdriver.
b. Completely remove the screws and shipping clips from each end of the bar assembly.
c. Remove the two bar end caps which cover each end of the aluminum bar extrusion.
d. Remove the screw holding the touch sense wire ring terminal to the boss in the bar
extrusion.
e. Carefully withdraw the end mount that houses the main (TS) PC board from the end of the
bar.
f. Unplug the connectors from the PC board that face toward the inside of the bar.
g. Tuck all connectors and wiring back into the bar, ensuring that the wiring is secured deep
enough to be out of the way during the cutting of the bar.
h. Carefully remove the rubber bumper pad from the end of the bar to be cut. (These are glued
on at the factory).

PN# 500-22700
Page 7 Rev. F, 03/11
i. Mark the bar to indicate the desired cut.
Note: For a DSB with the illuminated sign option, the bar should always be cut on the
end that houses the main (TS) PC board. This will be the end opposite the LED light strip.
j. Using a saw, cut the bar to the desired length.
Note: It is highly recommended that the cutting of the bar be performed by a band or
cut-off saw to produce a neat, straight, clean edge. However, with care, a hacksaw can
be used.
k. Using compressed air, blow out any metal shavings that may be inside the bar. Ensure that
the switch PC board at the opposite end of the bar is free of shavings. (This may require
removal of the end mount at that end).
l. Reinstall the two bar end caps which cover each end of the aluminum bar extrusion.
m. Reinstall the rubber bumper pad to the end of the bar. A small amount of instant adhesive
(such as Super Glue® - not included) may be used to permanently reaffix to the bar.
n. Retrieve the wiring from inside the bar. On a standard (non-illuminated) DSB there is only
one (1) wire harness. On the “I” (illuminated) version of the bar there are a total of three
(3) wire harnesses.
Note: If more than 4” [102mm] is cut from the bar, then the excess length of the wiring
harnesses must be equally shortened. This can be done by folding or rolling the harness
wiring back on top of itself and applying a wire tie or electrical tape to secure the loop.
o. Reconnect to the PC boards/base mounts. (The two LED wire harnesses of an illuminated bar
are interchangeable and may be plugged into either of the 2-pin connectors on the main (TS)
PC board.
p. Reinstall the touch sense wire ring terminal to the boss in the bar extrusion.
q. Insert both of the end base mounts (with their PC boards) into each end of the bar and
ensure that there is no interference to the operation of the limit switches at either end of the
bar.
r. Reinstall the two shipping clips as they were initially assembled.
s. See Section 6 for complete bar installation instructions.
7. BAR HANDING
7.1. PUSH TO EXIT SIGN INSERT:
A single reversible face insert has been provided with the standard DSB unit. This insert can be
flipped so that the position of the “PUSH TO EXIT” is at the desired end of the bar. To change
the orientation, remove one of the bar end covers, slide the insert completely out of the bar face
slot, flip it over and reinstall it into the slot (see Figure 9).
7.2. ILLUMINATED SIGN INSERT:
Two different face inserts (a left and a right hand version) have been provided with DSB units
which include the illuminated sign option. Each one will provide a transparent lettered “PUSH TO
EXIT” sign that will cover the LED light strip at either end of the bar. To change the insert,
simply remove one of the bar end covers, slide out the existing insert and replace with the
alternate insert (see Figure 9).

8. ELECTRICAL CONNECTIONS AND WIRING
8.1. DSB WIRING
The DSB is supplied with either a 16-foot [4.88 meter] long cable with traditional wire leads or
an ElectroLynx wiring harness. Either of these wiring devices may be used to connect power to
the main PC board of the DSB. The following figures and table identify the contact numbers,
wire colors and functions assigned for DSB power and DPST relay output:

The male connector of the cable or ElectroLynx wire harness is plugged into the 8-pin female
connector on the main circuit board so that the cable routes directly back into the end mount of
the DSB.
The DSB is operated by a control relay which changes state when the bar is touched. For
additional safety the DSB is a fail safe device. When the DSB receives power, the control relay
automatically energizes the lock. When the bar is touched, it changes state. For releasing a
magnetic lock, the following wiring diagrams (Figures 11 and 12) show typical connections of
the dual sense bar, power supply and a fail safe lock in use on single and double door exits
without an access control unit.
THE WHITE (NC1) WIRE MUST ALWAYS CONNECT TO THE INCOMING (+) POWER WIRE
FOR THE BAR TO OPERATE CORRECTLY.

Figure 12 – Double Door (No Access Control Unit)
Fail secure electric locks are normally not permitted for use with the DSB on required exit
applications. Normally open contacts, however, are available for special signaling applications
and for integration with the Request to Exit (REX) function of an access control installation. The
following wiring diagrams (Figures 13 and 14) show typical connections of the dual sense bar,
power supply and a fail safe lock in use on single and double door exits with an access control
unit.

Figure 15 shows the installation of an MOV in parallel with the magnetic lock. An MOV is
provided with each DSB. It is a black (or blue) disk-like component with two bare wires for
connection. The MOV acts to suppress the inductive kickback by a lock, which if left
unsuppressed will greatly shorten the life of the relay contacts. The MOV has no polarity, but in
order to function properly it should be spliced in to the wiring as close to the electric lock as
possible.

LOCK
+
_
Figure 15
IF A SECURITRON MAGNALOCK IS USED IN THE INSTALLATION, THE MOV IS NOT
NECESSARY AS THE MAGNALOCK IS ALREADY INTERNALLY SUPPRESSED.
THE POWER SUPPLY MUST ALWAYS CONNECT DIRECTLY TO THE MAIN DSB PC BOARD.
IN MAKING POWER CONNECTIONS ENSURE THAT PROPER POLARITY IS MAINTAINED.
The DSB operates on 12-24 Volts DC and is normally powered by the same power supply that
operates the lock. When connecting power to the unit, ensure that proper polarity is maintained.
As an additional safety feature, the DSB includes a low voltage sensing circuit. The unit will
keep working normally until input voltage declines to below roughly 9 Volts. At approximately
that point, the DSB automatically performs as if all power was removed (i.e. if a lock is being
controlled by the DSB, power to it will be cut and it will release).
8.2. DOUBLE BREAK WIRING
Many installations include a controlled access device such as a digital keypad or card reader.
Such devices typically have a REX (request to exit) input. When dry contacts close on this input,
the entry device will open the lock for the same amount of time that is programmed for entry.
Implementation of the REX input for exit can provide timed exiting. Also, for most entry
controls, the REX input must be used for exiting to avoid an alarm condition at the door.
If the REX input alone is used for exiting, a safety/reliability problem will exist. If the entry
device malfunctions, exit will not be possible and people may be trapped. It is recommended
that double break wiring which is supported by the DSB be used because of its two pole relay.
The DSB normally closed contacts are used to break power to the fail safe electric lock while the
normally open contacts trip the REX input of the controlled entry device. This releases the lock a
second time, hence the term, "double break". If the controlled entry device fails for any reason,
direct exit is still possible.
8.3. ADJUSTING TOUCH SENSITIVITY
After the wiring is completed the sensitivity of the touch sense must be adjusted. This can be
done at any time by removing the end mount cap from the main PC board end of the bar and
adjusting the potentiometer using a small flat tip (or Phillips) screwdriver (see Figure 16). The
potentiometer that controls the touch sense will increase sensitivity when turned clockwise and
decrease sensitivity when turned counterclockwise.
For initial setup, turn the pot clockwise without touching the bar with a small screwdriver until
you see the red LED illuminate. In this condition, sensitivity is set so high that the bar is
“sensing” or in release mode all of the time. Slowly rotate the pot counter-clockwise until the
LED goes off and then turn another 10 to 20 degrees counter-clockwise and stop. This is
generally a good initial setting. Before replacing the end cap, experiment by touching the bar
and observe that the touch sense LED goes on and off. Sensitivity can be increased somewhat,
but leaving the DSB set to just below the point of continuous release risks a condition of security
failure especially if the unit goes into a constant release mode.

This product was designed for use with Securitron Magnalocks. The Magnalock secures the door
with magnetic force only and therefore has no possibility of jamming and thereby denying
egress. The Magnalock also has internal electronics which allow it to release very rapidly. When
used with the DSB, which is also a fast device, exit is immediate and the impression a person
exiting gets is that the door is not locked at all. Other magnetic locks generally operate
significantly more slowly than the Magnalock.
9. APPENDICES
A. TROUBLESHOOTING
PROBLEM - The door will not release when the bar is touched.
Monitoring the touch sense operation of the bar can be done by viewing the red LED on the main
PC board next to the potentiometer (when the end mount cover is removed), which will
illuminate when the bar is touched. If there is no click or illuminated LED, try actuating the
mechanical movement of the bar. If the door does not release from the mechanical actuation, it
is almost certain that the overall wiring of the installation is at fault. If the door releases from
the mechanical actuation, the general wiring is probably correct but the touch sensor is not
reading touch. See Section 8.3 on how to adjust sensitivity. Another problem could be that
the touch sensor itself is not receiving 12-24 Volts DC power on the red and black wires.
Inspect the power supply and ensure that the input polarity is correct. If power is being applied
on the red and black wires it is still possible that power may not be getting to the sensor.
Inspect the connector that plugs into the main PC board to ensure that it is fully engaged and
check for loose wires. Finally, verify that the ring terminal that connects the sensor to the bar
has not come loose.
If the red LED does illuminate when you touch the bar and the door does not release, try to
mechanically actuate the door. If the door still does not release, the problem must be in the
lock/system installation wiring as it is nearly impossible to have a failed touch sensor relay and
mechanical switching circuit at the same time. Please review the wiring to make sure that the
DSB is correctly applied in the circuit. If the LED illuminates but only the mechanical function
releases the door, call the factory as the defect appears to be in the relay contacts and the main
PC board will have to be replaced.
PROBLEM - The door remains released constantly.
If there is LED indication when the bar is touched but the lock remains released, the problem is
probably in the system wiring which should be reviewed to be sure the DSB is correctly applied
in the circuit. If there is no LED indication, the touch sensor is probably adjusted too high
(review Section 8.3). Rotate the adjustment pot counter-clockwise while not touching the bar.
If this does not lock the door, some effect is probably keeping the relay in the de-energized
state all the time. (Remember, the relay is normally energized when the lock is secure to
maintain fail safe operation).
The most likely cause for the relay to remain energized is that the sensor "sees" an
overwhelmingly large signal as if someone was continually touching the bar. This will happen
if the bar is not properly isolated from a metal door.

PN# 500-22700
Page 12 Rev. F, 03/11
Make sure that the bar is installed with the plastic washers under the head of the mounting
screws.
Make sure there are no foreign objects or material creating a conductive path from the bar to
the door (e.g. metal blinds, etc.).
Make sure the bar is free to move and not stuck in the “exit” position. There should be 1/32”
clearance at each end of the bar between the end cap and mount flange. See Section 6.2.
The same effect will occur if the bar is used outside in the rain or if water is flowing down the
inside of the door. This moisture overcomes the electrical isolation needed between the bar
and door.
PROBLEM - The bar does not move.
If the bar does not move when it is pressed toward the door there are three likely causes.
The shipping clips were not removed. See Section 6.1, Figure 2.
There is not enough clearance at the ends of the bar. See Section 6.2.
The end mounts are not installed tightly and they have slipped causing the bar to bind on the
ends. Make sure the end mounts are horizontal and the bar end caps are not bound by
twisted mounting, tighten the mounting screws securely.
IF YOUR PROBLEM PERSISTS, CALL SECURITRON: 1-800-MAG-LOCK

4. Using a #1 Phillips screwdriver, back out the two (2) screws to release the base riser from
the rest of the end mount assembly.
NOTE: These screws should remain in place (in the holes of the spring plunger housing
and end mount) – This will help keep the plunger housing in place for time of
reassembly. (If the PC board and plunger assembly happen to come out of the end
mount, see procedure in step 4 for reassembly).
5. Place the end mount (with the PC board, plunger and screws) aside for reuse.
2 DRILL HOLE IN BASE RISER
1. Determine which side of the base riser to feed the flexible door cord shield into.
2. Scribe and/or center punch the base riser at location shown.
NOTE: Prior to drilling any holes the riser should be secured in a vise or similar
clamping device that will safely hold the part while it is being drilled.
3. Using a drill with a 1/8” diameter bit, create a “pilot” hole at the location shown. Drill
through the internal ribs and into the wire feed-thru channel in the center of the base riser.
4. Using a 3/8” diameter drill bit, follow the pilot hole to open up the holes in the part to 3/8”.
