Mechanism
Electro-mechanical head mechanism:
• Positive locking action for one passage at a time
• Self-centering mechanism to ensure complete rotation
into the home position
• Hyrdraulic 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
Interface
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
Models
• ATT
• ATT - ITC
