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 to activate

the optional drop arm feature
