SECURITRON MODEL TSH TOUCH SENSE HANDLE 

INSTALLATION AND OPERATION INSTRUCTIONS 

1.  DESCRIPTION 

Securitron's Model TSH is an exit device for doors secured by electric locks.  It can be employed 
as a door push or pull and is particularly well suited for 

aluminum frame glass doors

.  The 

assembly consists of a plastic base with an electronic touch sensor mounted inside and an 
aluminum handle which is used to pull or push the door open..  When the handle is touched, a 
relay in the sensor is tripped, releasing the lock.  The relay contacts are double pole with the 
second pole being optionally employed to shunt either an alarm system or the alarm function of 
an access control system.  The unit’s sensitivity is adjustable.  In the unlikely event of sensor 
failure, a push switch is mounted on the plastic base.  Depressing the switch has the same effect 
as activating the sensor by touch and therefore represents built in safety redundancy.  

The TSH 

cannot be used outside in rain conditions. 

As the TSH 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 

First, unscrew the handle from the plastic base (large Phillips screws) to reveal the base 
mounting holes.  Put the handle aside for now as initial mounting procedures concern the base. 

2.1  MOUNTING HOLE DRILLING 

Use the supplied template to set drilling positions for the two mounting holes.  There are two 
different hole diameters depending on the door type.  Hollow metal doors employ supplied 
machine screws and "blind nut" fasteners.  The second method is to simply use wood screws (not 
supplied) on a solid wood door.  By "solid wood", we mean a hardwood interior rather than 
pressed wood as the wood needs enough structural integrity to hold wood screws.

Note however 

that when the TSH is used on a solid door, the door must be core drilled to get the wire way cable 
to the hinge side for take-off via the supplied door cord

.  

For other door types, such as a chalk 

filled fire door, consult the factory for additional mounting accessories.

  Note that the Touch 

Sense Handle may not be used on a fire rated door that requires a fire rated latch 

(the TSH 

has no latch), but sometimes fire doors are used on openings where a fire rated barrier is not 
required, because the door type has been selected for other reasons (such as solidity). 

For a 

hollow

metal door

, drill two 3/8" (9.5MM) diameter holes only deep enough to get through 

the inner side of the door- not completely through the door. 

For a 

solid wood door

, you may elect to mount the handle with wood screws (not furnished).  

We recommend 1 3/4" #14 wood screws with a hex, pan, oval or round head.  Drill two 3/16" 
(5MM) diameter holes to a depth of 1 1/4" (32MM). 

2.2  WIREWAY HOLE DRILLING 

The TSH connects to its power source and to the devices it controls via a six-conductor cable 
with push-on connector (supplied).  Exit from the door may be via the supplied door cord which 
may be mounted at the top of the door where it is out of the way, or via any of many commercially 
available transfer hinges or pivots which serve to route the wiring off the door in a concealed 
manner.  A 

3/8" (9.5MM) 

wireway hole is then drilled into the door.  Note that 

the template is 

handed

.  The TSH can be vertically flipped to suit a right hand or left hand door but you have to 

know which way the aluminum handle will face in order to correctly orient the template. 

2.3  MOUNTING THE PLASTIC BASE TO THE DOOR 

In the case of a

 hollow metal door

, identify the two supplied blind nuts.  The nuts are used as 

follows.  Insert the nuts with the knurl engaging the edge of each hole.  Then utilize the supplied 
collapsing tool to collapse the nuts.  Use of the tool is shown in Figure 1.  Then, place a tooth 
washer under the head of each screw and mount the plastic base.  Do not over torque.
