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
