Fail-safe or fail-secure : How to choose the right type of motor

With our ALLIX gates – whatever the type of opening : cantilever, sliding or swing (with a hydraulic cylinder or embedded motor), you have the choice between a fail-safe or fail-secure (self-locking) motor system.

  • Types of motor

    To best meet your requirements, 2 motorised models are available.

    To help you with your choice, find out :
    -    On what site will the ALLIX gate be installed ?
    -    What are the requirements of the site and/or its users ?

  • In the case of power failure 

    In the event of a power-cut (fire, vandalism, work etc) what is required ?

    • You must free-up the accesses as soon as possible 

    In this case, the gate must be manually maneuverable without a key. Opt for the fail-safe motor !
    It is particularly recommended for housing complexes and public places, where users must be able to quickly leave the site.

    • It is essential to keep things secure by keeping the gate locked

    In this case, choose a fail-secure or self-locking motor system. A key will be required to open the gate (from the outside
    or from the inside). You must wait for the intervention of the maintenance, technical team or even emergency services
    to open the gate.

    The fail-secure or self-locking motor system is the most frequent and most suitable solution to meet the requirements of industrial, logistic or service sector sites.

    It should be noted, however, that this type of motor is equipped with a back-up battery that allows the gate to be free
    for a few hours (at least long enough to close the site once the incident is resolved – watch out though, this time is reduced when a lot of additional accessories are connected, because they use up the battery).

  • Our motors

    Whatever the site and its requirements, ALLIX gates can be equipped with the most suitable motors to achieve the best
    configuration. All the motors available are tested for 100,000 cycles and approved by the relevant organisations.

    All of our gates, regardless of the chosen combination (heights, passages, infills, motors) comply with the standard NF EN 13241.

    The motorised gates are systematically supplied with safety devices adapted to the speed of movement of the gate, its weight and its inertia force. The « motorisation » option includes safety edges on the posts, a safety edge on the gate leaf,  a set of VL presence detectors, a flashing light and area lighting.

  • For fail-safe motors 

    For ALLIX swing gates, with a hydraulic cylinder or embedded motor, the maximum dimensions are 3m per gate leaf, meaning a maximum of 6m for a double-leaf gate. Time to complete a cycle (one opening/one closing).

    For ALLIX cantilever gates without rails, the maximum length of passage is 8m.  The gate is equipped with a rack welded into the beam. It is neither visible nor accessible ensuring safety and clean lines.

    For ALLIX sliding gates, the maximum length of passage is 9m. The gate is equipped with a rack mounted on the outside of the beam.

    For ALLIX cantilever or sliding gates, the fail-safe motor has the option of the control board cabinet (height 1m, whatever the configuration of the gate) or control board column (at the height  of the gate).
    Travel speed : the opening time of a 6m gate is 26 seconds.  
     

  • For fail-secure/self-locking motors

    For ALLIX swing gates, with a hydraulic cylinder or embedded motor, the maximum dimensions are 3m per gate leaf, meaning a maximum of 6m for a double-leaf gate. Gate opening time : 26 seconds.

    For ALLIX cantilever gates without rails, the maximum length of passage is 10m.  The gate is equipped with a rack welded into the beam. It is neither visible nor accessible ensuring safety and clean lines.

    For ALLIX sliding gates, the maximum length of passage is 12m. The gate is equipped with a rack mounted on the outside of the beam. Travel speed of 9 to 12m/minute depending on the passage – the opening time of a 6m gate is 30 seconds and a 8m gate is 40 seconds.

    For ALLIX cantilever or sliding gates, the control board cabinet (height 1m, whatever the configuration of the gate) or
    control board column (at the height of the gate) are optional. These two additional options protect the motor and accessories from external risks (vandalism, weather) and add comfort (for the installation/commissioning but also adding space for additional equipment).  The logic controller is offset and the components are pre-wired.
