SlimStile EV ATT

SlimStile EV ATT

Tripod Turnstile for internal or external use

Tripod Turnstiles are compact and cost-effective entrance solutions designed for smooth and silent operation, less wear and tear and reduced power consumption, suitable for areas where there is a large flow of people.

SlimStile EV ATT (Alarmed Tripod Turnstile) offers the best security performance by means of a photocell and IR sensor alarming in case of unauthorised passage attempt. The system can be further enhanced by a sensitive lid and extra photocells with the ITC functionality (Improper Transit Control). The ATT-ITC version avoids passage simulation and improves the overall performance for the detection of unauthorised passage detecting if someone tries to jump over or crawl under the tripod’s arms as well as if someone tries to climb over the cabinet.

On receiving a signal from the access control system, or push button, this allows the passage of one person at a time. The status is shown on the LED way mode indicators, in entry and exit side. Passage in both directions is electronically controlled. The SlimStile EV ATT is available in Normally Closed (N/C) configuration to lock the mechanism until a valid authorisation signal is received, or in Normally Open (N/O) configuration to lock the mechanism in the event of attempted unauthorised entry. The N/O configuration also allows reduced power consumption and increases the life of the mechanism and passage throughput speed.

In case of emergency, the hub freely rotates for an easier exit. The drop arm option can be chosen which automatically drops the horizontal arm to allow free passage. LED way mode indicators are included as standard.
(*) External installation allowed under canopy.

Product Overview

SlimStile EV ATT

Tripod Turnstile for internal or external use

Stainless steel tripod turnstile with a small footprint. Single and double versions for indoor use and single version for outdoor use (if protected under a canopy.)




Casework: 304 grade grained stainless steel
Casework lid: 304 grade grained stainless steel
Tripod hub: Cast aluminium with painted grey finish
Tripod arms: 38mm diameter 480mm 304 polished stainless steel


Electro-mechanical head mechanism:
• Positive locking action for one passage at a time
• Self-centering mechanism to ensure complete rotation into the home position
• Hydraulic damper to ensure smooth operation
• Anti-backup device to prevent reverse rotation once the mechanism has moved 60° from home

Power Failure / Fire Alarm

• Either one or both directions can be fail-safe (standard), i.e. rotates freely, or fail lock, i.e. locks in the home position
• Fire alarm – emergency input. Input facility available for free voltage contact to effect fail-state
• Mechanism fail state will be the same as power failure choice
• Drop arm option: the horizontal arm drops to create passage for evacuation


LL2001Lite microprocessor control logic:
• One input for opening/locking in each direction
• Two protected outputs controlling opening/locking
• Four protected outputs piloting way mode indicators
• Two protected outputs counting passage in either direction
• Two OV output relays indicating availability of use or counting passage in either direction
• Two open collector NPN outputs to count passage or to indicate availability of use in either direction or activate the optional drop arm feature
• Four inputs for ATT & ITC features
• Serial Port – RS485


• Card reader mounting
• Remote control MP2000
• Push button control
• Pictograms
• LCD counter
• Drop arm
