4.2 Access control system (ACS)
The THT-100 is designed to integrate with most access control systems by means of an
authorization signal. When the THT-100 receives the signal from ACS, the internal control system
releases the locking solenoid in the desired rotating direction.
4.3 Security
Several Security features are designed into the THT-100 unit. The following devices are typical
features found in most units.
•
Restposition
: When the rotor arms are in their respective locked rest position, they will be
held tight by the force of locking pawls and ratchet assembly. This will prevent movement of
the rotor arms by hand when the unit is in its locked home position
•
Barrier Unit:
Prevents unauthorized entrance by individuals trying to tailgate in the opposite
direction of a passage by an authorized user.
•
Shield Assembly:
Creates a secure compartment area where the rotor arms travel and
authorized users pass.
