What Makes a Safe Electric Roller Garage Door?

By Nathan | March 20, 2014

The DHF have issued a further document to try to clear this question up even further.
Any company selling and installing electric roller garage doors, whether they be switch controlled or remote control operated have a duty to ensure the roller door is safe for the intended use. Unfortunately for the sake of cost saving and undercutting competitor prices many companies are blatently ignoring the regulations and requirements here in the UK.
It has been quite difficult sometimes to explain the law as it stands but the DHF have just released a document to hopefully clarify the requirements for electric roller door in particular and used for domestic applications mainly.
A lot of the requirements are common sense but the biggest contentious point is whether a roller door needs a ‘leading edge safety sensor’ or not and if not what is wrong with simply fitting a cheaper infra red beam detector at low level. As we have said in many previous blogs and FAQ’s the use of an infra red beam is not compliant on its own and hopefully the following document extract explains this clearly. Do not accept from anyone that if you have a roller garage door installed with an infra red beam it is OK, because it is not OK!!!

Extract from DHF recently released document:

1. What laws do you need to comply with?

The law requires garage doors must be safe when first placed on the market or put into service. The main legal requirements that affect the safety of new powered garage doors are detailed in two pieces of European legislation:

  •  The Supply of Machinery (Safety) Regulations 2008 (SMR)
  •  The Construction Products Regulation 2011 – EU No. 305/2011 (CPR)

Both of these require the garage door to carry a CE mark and to be accompanied by official declarations: a “declaration of conformity” in the case of SMR and a “declaration of performance” in the case of CPR.
The responsible person must also maintain and keep a technical file detailing how regulations have been complied with; this file must be produced whenever required by enforcement authorities.

2. What about the European standard?

The “harmonised” European standard for garage doors is BS EN 13241-1:2003 + A1:2011. Under SMR, compliance with the standard is optional BUT a compliant door will be presumed to conform to the SMR legislation.
If the door does not fully comply with the harmonised standard, the person responsible must demonstrate that an equivalent level of safety has been achieved.
Under CPR, compliance with certain clauses of the harmonised standard is compulsory; one of these is the clause relating to operating forces of powered doors.

3. What does this mean for safety on the main closing edge?

The minimum requirements for safety on the closing edge are summarised below:

Type of Control                                                             Conditions of Use

Trained Users                      Trained Users                  Untrained Users
no public present          public may be present      public may be present
Hold to run (i.e. continuous
pressure required) located                                                0                                                  *                                             ***
in a safe place in sight of
door

 

Impulse (i.e. continuous
pressure not required)                                                         **                                                 **                                          ***
located in a safe place in
sight of door

 

Impulse not located in sight                                              **                                                  ***                                        ***
of door

 

Automatic                                                                            ***                                                  ***                                        ***

 

Key to table
0     =     No additional safety required
*      =     Key switch or similar to prevent unauthorised use
**   =     EITHER force limitation OR comprehensive presence detection
*** =    EITHER a combination of force limitation and auxiliary presence detection OR comprehensive presence detection

1 By comprehensive presence detection we mean a system of presence detection which ensures that in no circumstances can a person be touched by the moving door. The system must comply with BS EN 12978:2003
+ Al:2009 as well as being able to detect obstacles when tested in accordance with BS EN 12445:2001.
2 By auxiliary presence detection we mean a system which would detect a person or obstacle on the floor on one side of the door; not necessarily compliant with BS EN 12978:2003 + A1:2009. Must always be combined
with force limitation as the primary safety system.

Note the following:

  • Hold to run controls must be located in a safe place and in sight of the door.
  • There is NO situation where a simple photoelectric cell on its own is sufficient.
  • A comprehensive presence detection system is always considered adequate (but is relatively expensive).
  • Automated doors always require force limitation unless protected by comprehensive presence detection.
  • Force limitation can be EITHER inherent (built into the operator) OR external (such as a safety edge). In either case the door must be able to pass the force test in BS EN 12445:2001, clause 5.
  • Tubular motors do not generally have inherent force limitation; a safety edge will normally be required to comply with the standard.

4. Conclusion

In order for a powered garage door to be legally placed on the market today, you must, as a minimum, be able to answer YES to ONE of the following questions:

1. Is the door controlled exclusively by a hold to run control located in a safe place within sight of the door?
2. Is the door protected by comprehensive presence detection?
3. Does the operator have inbuilt force limitation?
4. Is the door fitted with a safety edge?
(In the case of 3 or 4, you may need to fit auxiliary presence detection in addition to force limitation, depending on the level of risk as defined in the table above.)
