THT-100
Barrier Unit
4.4 Optional and Configuration Features
Items indicated by an asterisk(*) are noted as optional.
Rotation Detection Switch*
The optional rotational detection switch is located within the Top Channel Assembly. When an
authorized user rotates the unit, this detection switch sends a dry contact closure back to the
ACS to notify that the unit has been turned. The unit will then reset and wait for additional
authorizations.
Home Position Switch *
When the THT 100 reaches its resting position, this is called the home position. A small micro-
switch is activated notifying the control system that the unit is in its home position.
Solenoid activation switch*
When a solenoid is activated a small micro-switch is activated notifying access control that the
rotor arms are unlocked.
Traffic Lights*
Optional traffic lights can be installed in the end posts of the shield surrounding the walk path.
The LED's illuminate Red when the unit is locked and in stand-by waiting for an authorization.
When a valid card read signal is sent from the Access Control System to the THT-100, the LED's
on the respective side will turn Green. Once a user passes through the unit, the LED's will turn
back to Red.
