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

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.

Page 9 Rev. F, 03/11
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.
