THT-100
4 Operating concept
4.1 Operating functions
There are many available operating functions of the THT-100 below is a list of typical
configuations. Keep in mind that only one configuration is possible per assembly and is
determined when the unit is manufactured. Changing the configuration of the unit can require
major mechanical changes. Refer to your order or have an authorized Boon Edam Inc. Service
provider inspect your THT-100 if you should have questions regarding the configuration.
Fail Lock - When power is turned off (denied), this configuration provides Fail Lock in
the specified direction. No rotation is allowed in the specified direction. All Fail Lock
units come equipped with a mechanical key override to override the locking system to
allow for free spinning of the rotary arms.
Key Override (Mechanical) - This key switch is typically found on any Fail Lock
direction unit on the underside of the top channel near the upper flange assembly.
When switched to override mode, Fail Lock function can be bypassed for free egress in
the selected direction. Note: FL/FL units will have two key overrides.
When power is restored to the unit, the system will automatically restore to its normal operating
function.
Fail Safe - When power is turned off (denied), this configuration provides Fail Safe
rotation in the specified direction of travel.
Note: Any combination of the above mentioned functions is available in the following
configurations:
•
Access Control Rotation (i.e., Card read activation)
•
Free Rotation
•
No Rotation
Direction types (Clockwise, Counter Clockwise)
The typical THT-100 rotates in a Counter Clockwise (entry from non-secure moving into the
secure) direction. When authorization is granted, the unit can be manually rotated for one
segment (120 degrees) and return to the rest position and lock. Likewise, for exiting from the
secure to the non-secure side, the unit rotates in a Clockwise direction. Note: Some units may
be ordered with Clockwise entry and Counter Clockwise exit. Always refer to your order
for proper rotating direction.
•
Controlled access CCW and CW direction: Both rotating directions require authorization.
The rotating section of the unit will become unlocked for the desired direction upon Access
Control System (ACS) signalling to the THT-100 control system that access has been
granted.
•
Controlled access in one direction and free access in the opposite direction: Only
one direction requires authorization. The other direction does not require authorization and
rotates freely when pushed.
•
Controlled or Free access in on direction and No Access in the opposite direction:
Access is only allowed in one direction (via access control or free access in). The opposite
direction does not allow traffic to pass.
•
Free Access in both directions: There is no access control connected to this type of unit
and it will freely spin in either direction.
