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.
