Essential Pre-Installation Checks

SECURECOIL® has been designed for use with a security door.

This must have an adjacent return wall, and meet the following basic requirements:

  • A solid door (if in doubt contact the supplier of your door);
  • Heavy duty door hinges and frame; and
  • An adjacent return wall on the hinged side of the door (hinged either left or right) constructed in masonry or concrete (see DIAGRAM A).

Installation should be completed by a builder, joiner or a suitably qualified tradesman.

When a door is attacked, SECURECOIL® can withstand a loading exceeding two tonnes. Under attack, all other elements of the door installation must be capable of withstanding such loadings, because otherwise there is a risk that damage could occur to the door frame or hinges.

A typical installation is illustrated in DIAGRAM A on the right, (the same applies to a right hand hinged door).

NB: Please refer to this Diagram during the installation process.

At this point there are two variants of SECURECOIL® (Model A and Model B) and to choose the correct one, simply measure the distance between the centre of the door and the return mounting wall.

Distance D (as shown in Diagram A) determines which model of SECURECOIL® should be used. In some cases the door frame is mounted directly to the adjacent wall, in others a nib wall exists as illustrated above. Whichever is the case, the door frame depth including architrave and/or nib wall return is included in the overall measurement.

Each variant has adjustment within the range shown below:

If distance D is between 470mm and 560mm - use SECURECOIL® - Model A
If distance D is between 545mm and 640mm - use SECURECOIL® - Model B

If distance D is more than 640mm please contact your supplier and we can, in most cases, assess the requirements and supply them with a bespoke, one-off design, at extra cost.

These measurements are critical to ensure that the SECURECOIL® is working at the correct angle.

Fitting the SECURECOIL® Door Bracket

To ensure the most effective operation of the SECURECOIL®, the door bracket should be fitted at the centre of the door. Simply measure and mark the width and height of the door to find the centre point.

The centres of the screw holes for this bracket are 30mm to each side of the centre point on the horizontal axis through the centre of the bracket, and we recommend the use of a level to ensure the bracket is correctly positioned, and level.

Screws are supplied. On the door bracket these are No 12 wood screws 1½” long (M6 x 40mm). These are the minimum length that should be used.

Fitting the SECURECOIL® Wall Bracket

It is essential that the wall bracket is on the same level as the door bracket, this ensures that the SECURECOIL® locating arm enters the middle of the slot in the door bracket without fouling. In order to ensure the correct operating angle of the SECURECOIL® it is necessary to calculate the distance W to the centre of the bracket as shown in Diagram A.

Please note, that this figure varies, dependent upon the distance D. The correct measurement W for your fitment is simply calculated by multiplying W by 0.454. For example, if the value of D is 480mm, 480 x 0.454 = 218mm. In this case, 218mm is the distance to the centre of the wall bracket from the plane of the inner-face of the door (ref - Diagram A).

This is the distance to the centre of the wall bracket, from the plane of the inner-face of the door and hinges (ref - Diagram A).

To find the centre point for the wall bracket, use a level and mark the distance W. The centres of the two screws are each 30mm from this mark as illustrated.

Fix the wall bracket at W and adjust and locate the arm into the door bracket. As already noted, the end of the arm must enter the centre of the slot in the door bracket without any fouling. After final adjustment, check that the arm locates firmly.

The supplied screws to be used to attach this bracket to the wall are, No 12 wood screws 1¾” long (M6 x 45mm) using brown Rawlplugs or equivalent. These are the minimum length that should be used.

Ensure that the labelled side of the wall bracket is uppermost.

Adjusting the SECURECOIL®

Once the brackets have been correctly fitted, the length of the SECURECOIL® is simply adjusted by loosening the locknut and screwing the locating arm in or out, so that it slots firmly into the door bracket. The adjustment of the threaded section should not exceed 146mm from the bottom of the locknut to the end of that element.

Adjustment should be such that the end of the arm just clears the vertical part of the slot in the door bracket when pulled back, and also clears either side of the slot. It should snap into the locating socket securely. It should not be left loose to the point that it can be rattled (ie the locating spring should be under a degree of compression that still allows easy deployment).

Once the correct fitment has been achieved, the locknut should be tightened using an appropriate tool. The use of grips to adjust the SECURECOIL® is not necessary and might damage the surface finish.

Lastly, having fitted the SECURECOIL® and ensured that it is working correctly, you must fit the retaining C clip on the wall in order to keep the device out of the way when not in use.

Operating Instructions / Safety Precautions

We have developed a sticker to be put on the door beside the door bracket, this includes the following information:

 The spring system in the SECURECOIL is necessarily strong - remember that if the door is charged, the spring system will slam the door closed

1)      Make sure that the door is fully closed

2)      Unclip  the SECURECOIL and rotate the tip to the door bracket

3)      Grasp the device by the locknut and pull back enough to allow the tip of the arm to slot into the door bracket

4)      Release your pressure, keeping your fingers away from the door bracket - the SECURECOIL is now deployed

 

You can safely open the door by 100mm / 4" to check any caller, receive a small parcel, or examine credentials.  When giving or receiving something through the gap in the door, do not leave your hand in the gap in case the caller attempts to force the door

 

  5)    To release the SECURECOIL make sure the door is fully closed, then again pull the device by its locknut back into itself, and slide the tip out from the              door bracket to release it

  6)    Rotate the device back, and put the SECURECOIL into the clip. You can now open the door normally

 

     USE YOUR SECURECOIL AT ALL TIMES

 

Be aware when children, vulnerable adults, or those unfamiliar with the device are in the area, and avoid them putting their hands in the gap if the door is held open

 

  The greater the force needed to engage the device, the safer you will be

 

  We recommend that the user or users practice engaging and releasing the SECURECOIL several times in order to be comfortable with its use
