Description
The Model TSH touch sense handle 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. Touching the handle trips a relay in the sensor, 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.
