SECURITRON MODEL TSH TOUCH SENSE HANDLE

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.

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.

Page 3 Note installation of the MOV in parallel with the electric lock. The MOV is supplied loose with the TSH. It is a black or blue disk-like component with two bare wires. The MOV suppresses inductive kickback from the lock which shortens the life of the relay contacts if not suppressed.
Page 4 The proximity reader projects an electric field of considerable intensity and we have seen rare cases where this can be picked up by the TSH. It depends on the power of the proximity reader and the nearness of the reader on the outside of the door to the handle on the inside.

Page 6 The Magnalock also has internal electronics which allow it to release very rapidly. When used with the TSH, which is also a fast device, exit is immediate and the impression a person exiting gets is that the door is not locked at all. Other magnetic locks generally operate significantly more slowly than the Magnalock.
