SECURITRON SERIES TSB-3 TOUCH SENSE BAR
INSTALLATION AND OPERATION INSTRUCTIONS
1. DESCRIPTION
Securitron's Model TSB-3 is an exit device for doors secured by magnetic locks. The assembly consists of
an aluminum bar available in lengths to fit on standard U.S. door openings: (36", 42", and 48"),
PolyCarbonate end pieces to mount the bar on the door, and an electronic touch sensor mounted within
the bar. Fasteners for metal doors are included. For through door mounting please call factory for a no-
charge TSB-TDM kit. Note that US type or metric fasteners are supplied depending of the version of
the bar which has been ordered. The metric version part numbers include the suffix: “M”. When the bar
is touched, a relay in the sensor is tripped, releasing the lock. The bar's sensitivity is adjustable. In the
unlikely event of sensor failure, a push switch is mounted on the back side of the bar. Depressing the
switch has the same effect as activating the sensor by touch and therefore represents built in safety
redundancy. The TSB cannot be used outside in rain conditions.
As the TSB-3 is normally used to allow egress on an electrically secured door, make sure that
you are complying with applicable building codes for your area. Check with your local building
department and/or fire prevention department.
2. PHYSICAL INSTALLATION
2.1 MOUNTING HOLE MARKING
The first step is to plan and mark the mounting hole positions. Be sure that you have the correct length
bar for the door and begin by removing the screws that secure the end caps on both ends of the bar. If it
appears that the bar is longer than it should be for the door, see Section 2.6 for cutting instructions.
Note which end has the sensor (circuit board) in it. This is the end that should be mounted on the
hinge side for easiest wire exit from the door.
For mounting hole drilling, we supply a template located at the end of this instruction manual, although it
is generally preferable to hold the bar in position and use it as a "self-template." The templates are
particularly valuable if door preparation is to be done in advance. In setting your mounting holes, there
are three concerns:
They must be level or the bar will be tilted.
They must be the correct distance apart.
They must be correctly placed "left/right" on the door.
Leveling is best done by use of a carpenter's level. If one is not available, measure from the mounting
hole positions on each edge of the door to the door bottom. This is not as effective as it assumes that the
door is level which is not always true. Note that in general, US building codes require the height of the
bar above the door bottom to be between 30 and 44 inches.
If the bar is used as its own template, you will automatically get correct separation between the mounting
holes. If you use the templates, note that there is a line drawn on each template which must line up with
the outer edge of the plastic end pieces on the bar. After you've mounted the templates, hold up the bar
to make sure the end piece lines up to get the correct distance.
Left/right placement on the door is an important point. In most installations, the bar should be centered
on the door. This produces the most attractive result. However, if the door has a vertical door stop on
the edge that swings open, you may need to shift the bar somewhat towards the hinge side to avoid
scraping the stop when the door opens. You should always experimentally position the bar on the
door and open the door to see that there is no interference. Finally, if the installation is on an
aluminum frame glass door, make sure you don't position the bar so that the mounting screws go into the
glass. On standard doors, keeping the mounting holes at least 3/4" (19 mm) from the inner edge of the
aluminum will be safe.
2.2 MOUNTING HOLE DRILLING
There are three different procedures depending on the door type. Hollow metal doors employ supplied
machine screws and "blind nut" fasteners. This method leaves the outside of the door unaffected. Longer
machine screws and sex bolts may be used on hollow or solid wood doors, solid metal doors, or chalk filled
fire doors, the TSB-TDM kit for this type of mounting can be ordered from the factory at no-charge. With
this method, the sex bolt heads do show from the outside of the door. Note that the Touch Sense Bar
may not be used on a fire rated door that requires a fire rated latch (the TSB-3 has no latch), but
sometimes fire doors are used on openings where a fire rated barrier is not required, because the
customer has selected this door type for other reasons (such as solidity). The third method is to use wood
