Door mounted operator
Suitable for 2-, 3-, 4-, 6- and 8-panel doors. Operator is attached to the door panel, so it doesn’t take up space above the door. Excellent solution for smaller and medium-sized doors, for example in industrial buildings, smaller fire stations and barns.
Motor: 24V motor operates with single phase electric current
Safety equipment:
- An electric eye system in line with the door prevents the closing of the door if there is some physical object between the detectors.
- The door opening machinery includes a motor overload activated shut-off switch, which overload would be caused, for example, by a physical object preventing the opening or closing of the door. This prevents a breakdown of the machinery itself.
- Folding doors that include a built-in entry door have a disconnecting switch that prevents the opening of the folding door when the entry door through it is open.
- Three push-button switches, Open-Stop-Close, beside the door opening.
- The door is also operable manually during power outages.
Control devices for the door opening machinery:
- Push-button switch box (Open – Stop – Close)
- Remote control switch
- The door opening machinery can be hooked up to the building’s physical access system
Additional available features:
- Canceling electric eyes (the door automatically closes once a vehicle has crossed the beam of light to the electric eye)
- Radar utilizing door opening systems
- Control through VIRVE signals
- Magnetic loop door opener (installed in customer prepared conduit grooves)
Chain operator
For 4-, 6- and 8-panel doors. Suitable for big doors, as well as places where doors are opened frequently, such as, for example, at fire stations, carwashes and factories.
A separate rail for mounting the door opening machinery will be mounted above the door. The machinery will then be installed upon this rail.
This machinery will be operated with normal grid electric current (3-phase current)
Safety equipment:
- An electric eye system in line with the door prevents the closing of the door if there is some physical object between the detectors.
- The door edges that close against the building structure contain sensors.
- Folding doors that include an entry door have a disconnecting switch which prevents the opening of the folding door when the entry door through it is open.
- Three push-button switch box, Open-Stop-Close, beside the door opening.
- The door is also operable manually during power outages.
Control devices for the door opening machinery:
- Push-button switches (Open – Stop – Close) in switch box.
- Remote control switch
- The door opening machinery can be hooked up to the building’s physical access system
Additional available features:
- Canceling electric eyes (the door automatically closes once a vehicle has crossed the beam of light to the electric eye)
- Radar utilizing door opening systems
- Control through VIRVE signals
- Magnetic loop door opener (installed in customer prepared conduit grooves)
Entry and double door specifications
The opening for an entry door has a maximum width of 1395 mm.
