The TRS 280 tripod turnstile is designed for an economic and dissuasive access control and can incorporate access control devices such as: card readers, coin/token acceptors, ticketing systems, etc ...
Its mechanical design is strong and reliable allowing 20 different configurations to suit all architectural requirements in terms of pedestrian access control.
Description
1. Stainless steel sheet frame.
2. Front and rear sections made of stainless steel locked from inside. These sections can not be opened before upper cover removal. They are designed to incorporate user control equipment such as card reader, coin acceptor, proximity reader, etc.
3. Upper cover in stainless steel with lock, to ease access to the turnstile mechanism and to open the columns.
4. Tripod turnstile mechanism with solid steel arms and capstan on ball bearings, protected by a black PVC hub cover. Electromagnetically  perating locking bolts mounted on self lubricating bearings to lock arms.
Hydraulic adjustable pressure movement shock absorber ensuring silent smooth operation and progressive slowing down of the arm rotation even when used with force. Reversed rotation prevented by the anti pass back device.
5. Stainless steel arms with locking device preventing the arm from being removed without appropriate tools.
6. Programmable electronic control logic TR6 (see relevant Technical Data Sheet)
7 Each gate is designed to accommodate an orientation pictogram display in one or both directions (optional)
8. Floor fixing by means of expansible plugs.
Operation
The TRS 280 turnstile can operate in 5 different modes.
1. Access permanently free
2. Access permanently mechanically locked
3. Access mechanically locked with automatic unlocking device to give free passage in case of power failure. (Free-rotation)
4. Electrically controlled access
5. Access electrically controlled with automatic unlocking device to give free passage in case of power failure. (Free-rotation)
The operation mode is defined by specifying the code number above for both directions, which corresponds to the operation selected.

Conventions:
Direction A = housing at right hand side of the walkway
Direction B = housing at left hand side of the walkway
Example:
Turnstile free in direction A and electrically controlled in direction B with automatic unlocking device: this is a TRS 280 AI-B5 type turnstile.
Anti-corrosion
Internal mechanical parts are treated by zinc coating and passivation.
