Safety Edges

SAFETY EDGES

Safety edges have become increasingly popular with gate installers in recent years and with good reason. A safety edge provides a simple and effective method of protecting a specific part of the gate from causing a sheering, crushing or trapping incident. This greatly increases the likelihood of a gate passing a force test, but there is one more reason why safety edges have become so popular. They will not falsely trigger.

Let’s compare a gate system that uses just current sensing with a gate that uses just safety edges. The gate with current sensing is sensitive across the whole of the gate; however, it is much more sensitive at the leading edge and much less sensitive at the hinge. This means that a large gate leaf will pick up more false positives due to wind or other site conditions. Current sensing systems must also switch off the current sensing when they get close to their physical stop position. This is to prevent the current sensing system detecting the physical stop as an obstruction and is usually referred to as tolerance. These 2 factors (site conditions and tolerance) can make a current sensing system very hard to set up perfectly. A purely safety edge system will never suffer from a false positive but it can only detect an obstruction where the edge is fitted. This can lead to lots of edges being used on a gate, increasing the systems cost. Usually, 2 or more safety systems are used together to provide the safest possible gate for a reasonable cost.

In this section we will talk about the different types of safety edge available and in what situation you might use one.

COMPATTA & MAXXI CND
Brochure

The Compatta CND represents the latest advancement in safety edge design. This fully compliant and CE marked edge uses an 8k2 resistive strip at the tip of the edge to give incredibly fast reaction times, limited only by the control unit and motor. Further more, like other safety edges in our range, the Compatta CND can be quickly and easily cut down on site to any length. Our safety edges have been specially designed to make them easy to work with and quick to install. A wireless kit can be fitted internally on this safety edge.

  • IP67 resistive strip with fixed resistive end caps provides quick cut down system
  • Fast reacting edge from multiple directions makes gates incredibly safe
  • Versatile edge can be cut down by any amount while on site
  • 90mm (MAXXI version) & 60mm profile, 8k2 resistive edge, built- in wireless version available
  • Perfect for use on a sliding gate

MultiCT CAT 2/3 Edge
Brochure

The Multi Safety Edge is an incredibly easy to use edge and one of our favourites, call us up and ask us what we recommend and we will probably start talking about the Multi. The reason is simple, you can use it as a CAT 2 or a CAT 3 edge depending on which system you prefer. They can be wireless and are very quick and easy to fit as you can cut 400mm straight off the bottom without having to open the edge to make adjustments. A wireless kit can be fitted internally on this safety edge.

  • IP67 internal NO 8k2 switches provide the best CAT 3 safety edge system on the market
  • Join multiple edges together for gates of any height or width
  • Fit a CAT 2 wireless system inside the edge
  • Cut the bottom 400mm off the edge without needing to move any internal switches (3 minute install time)
  • Comes in lengths of 1.2m, 1.6m, 2m, 2.5m, & 3m with an 80mm profile

Multi 8k2 Resistive Safety Edge

Techno Edge
Brochure

Just like the Multi the Techno can be configured as a CAT 2 or CAT 3 system. This slimline resistive edge is perfect as a secondary safety device but we do not recommend using this thin edge as your main safety device as it lacks a deformable rubber strip to absorb an impact. A wireless kit can be added to this safety edge.

  • IP67 internal NO 8k2 switches provide a CAT 3 safety edge system
  • Join multiple edges together for gates of any height or width
  • Slim profile of only 25mm means the edge can fit into tight space

CMO NC Mechanical Edge

There are lots of different safety edge designs on the market but the CMO is one of the oldest and most reliable. Rather then using a Normally Open resistive contact, a Normally Closed contact similar to a photocell is used. This has the advantage that the device will fail safe and is fully CE marked. The system can be made to be CAT 2 with the addition of a CAT 2 SCHED device or wireless safety edge kit. A wireless kit can be added to this safety edge.

  • Fully compliant mechanical safety edge (CE marked)
  • Comes in lengths up to 3m but can be adjusted to any size
  • Add a wireless kit or SCHED controller to make the system CAT 2

RADIO MOBILE
Brochure

The Radio Mobile comes in 2 main forms. The first is a stand alone transmitter which you can add to any system past or present; this will allow a wireless link between any device and the radio receiver. The second version is designed to work with the Multi safety edge. This transmitter fits nicely inside the edge so there are no loose wires.

  • Uses standard AA batteries for easy maintenance
  • 2 Year battery life
  • 15M recommended range
  • Multi safety edge version fits inside edge
  • CAT 2 safety edges system

SCHED Safety Edge Controller
Brochure

The SCHED is a CAT 2 safety edge controller which accepts up to 4 8k2 resistive inputs and provides 2 NC (normally closed) outputs. This allows older gate systems to be quickly and easily brought up to EN12453 standards providing the control panel has a stop and revers feature, such those found on our Gate 2 DG.

  • 4no 8k2 inputs
  • 2 channel NC out puts
  • Compatible with any control system
  • CAT 2 Fully complaint with EN12453
