This is the most simple form, and is used primarily for pedestrian traffic. It is not recommended for forklift traffic, but can be used in conjunction with other activation forms.
These can be used for either pedestrian traffic or Forklift traffic (depending on the positioning of the pullcord). The cord length is variable, and they operate by a pulse contact, similar to a pushbutton.
Induction Floor Loops
These will only operate by an object consisting of substantial metal, such as Forklifts or trolleys. Very popular for high trafficked areas, and usually done in conjunction with pushbuttons to allow pedestrian movement.
Can also be used to restrict pedestrian movement if p’buttons are omitted.
Installation of this must be looked at carefully. It is usually only suitable for concrete or asphalt floors, in which a saw cut is made to insert the cable. This is grouted or epoxied into place.
This is suitable for pedestrians or Forklifts, but is primarily used for just Forklifts. Usually a good option if there are only a few Forklifts are using the opening, and especially good when there may be considerable cross traffic that may unnecessarily activate the door. Also good for restrictive entry. Very easy to install.
Care must be taken if there are other remote operations in the vicinity of the door, although frequencies can be changed to suit.
IR Motion Sensors
These are great for all forms of traffic, as they activate by any movement or presence in the location of the doorway. Great if pedestrians need hands free operation. They may be limied in openings which experience a lot of cross traffic, since the door may open unnecessarily, unless our NEW directional control IR sensor is selected. This sensor can determine if a vehicle is moving away or across the opening, therefore restricting unnecessary operation of the door
Not often used, but are good because there is a very defined activation area. Downside is that the PEs may be highly exposed to damage, due to being positioned away from the door, but close to the potential pathway.
These are used for access control, and can be connected to DMF doors, but it is recommended that they are not supplied by DMF. It is preferable that the security contractor for the client supplies these.
Integration with machinery
The DMF doors can be integrated with most machinery, including pallet lifts, conveyors, carwashes, fire alarms etc, so that the door will open or close upon a signal from the machinery.
This is a sophisticated array of light beams within the Efaflex rapid roll door that reacts very quickly to any obstruction occurring within the opening.
