Care Instructions

DOM locking technology is manufactured for heavy duty use and with the best locking features. Each cylinder is a product of utmost mechanical precision. To maintain the interaction of the single parts and therefore the functionally of the cylinder as long as possible, regular and thorough care is strongly advised. The locking cylinder, however, is only part in a door. The lock and fitting must also be considered. It is the interaction of these components: • cylinder • lock • fitting • door • frame that allow the locking of a door.

The smoothness of the lock and the correct, unstrained position of the fitting are also essential for proper functioning of the cylinder.

Furthermore, the door must not be under strain when closed. In any case of trouble therefore always check the interaction of all parts. Please keep in mind that it feels different to lock a door with the disk system of the DOM diamant steel cylinder than a door with the DOM pin cylinders.

Regularly apply DOM service spray to all DOM cylinders once a year.

DOM diamant cylinders are equipped with a disk locking mechanism. They are sufficiently lubricated with a fluid resin-free lubricant upon delivery so that their unimpaired locking features are guaranteed for a long time. To ensure, however, that the cylinder does not “run dry” due to heavy use, apply DOM service spray from time to time.

To make sure that care measures are not neglected and to maintain the high security value of your DOM locking technology, we recommend you appoint a specialist for care and maintenance who has the required expertise and enjoys your confidence. Only by abiding with DOM care instructions is the proper functionality of your DOM locking cylinders ensured.

A service contract makes your locking cylinder a long-lasting investment in your security.

Product Information

In accordance with the manufacturer’s product liability as defined in the product liability legislation the
following information on locking cylinders shall be taken note of.

Non-observance of this information discharges us from our liability

1. Product information and intended use
A locking cylinder in the sense of this definition is a generally interchangeable component which is installed in locks, fittings, devices, doors or similar products which are designed for this. Other cylinder versions shall be treated correspondingly. For proper operation, each locking cylinder is delivered with at least one key. Technical terms for locking cylinders or systems –as far as they are not explained in this catalogue – are explained and/or illustrated in DIN 18252 part 1. Concerning these technical terms and designations the following shall be observed to ensure the intended use.


1.1 Locking cylinders may unconditionally be installed in locks, fittings, devices, etc. only if these locking cylinders comply with a dimension standard (e. g. DIN 18252 part 2 for profile cylinders) and if such locks, fittings, devices, etc are expressly designed for locking cylinders in accordance with this standard. In all other cases, the manufacturer, dealer, processor or user of such locks, fittings, devices, etc. must establish with certainty that the chosen locking cylinder may be installed and used as intended. Mandatory legal regulations must be observed. For example, locking cylinders with knob, turning knob or similar handles must not be installed in panic doors.

1.1.1 In the case of doors prone to burglary, the (VdS compatible) locking cylinder installed shall be protected with a VdS approved anti-burglary escutcheon with pull protection of class B or C. Such escutcheons comply with DIN 18257 class ES2 – ZA or ES3 – ZA. As far as the locking cylinder has its integrated pull protection () or is a modular cylinder, the DOM VdS certified locking cylinders may also be protected with a VdS approved escutcheon without pull protection of class B or C. Such escutcheons comply with DIN 18257 class ES2 or ES3.

1.2 Locking cylinders which may be exposed to vandalism shall protrude no more than 3 mm from the protective fitting into which they tightly fit. The level of anti-burglary measures shall comply with the respective requirements (see e. g. DIN 18252).

1.3 The installation of locking cylinders shall be executed in such a way as to ensure that no other forces are brought on the cylinder than at the intended attachment points or other than caused by normal use. Furthermore, no external forces may be brought on the lock cam or in swivel direction on the closing lever by the usage of the key.

1.4 For wet or cool rooms, direct weather impact, use in an aggressive, corrosive environment or near the sea, locking cylinders must be customised accordingly. The same applies for locking cylinders which are intended for use in very dusty environments.

1.5 Usually, a profile cylinder with two locking sides (double cylinder) may not be operated if a key is inserted from the other side. If this is desired, however, you may choose a cylinder which is equipped for that purpose.

1.6 For proper key operation, the torque may only be exerted on the key if the key is completely inserted into the keyway.

1.7 Locking cylinder and key are a functional unit. We only assume liability for our original products.

1.8 All keys for locking cylinders supplied at a later point of time shall be immediately checked for proper functionality with the corresponding cylinder upon delivery.

Misuse

2. Misuse, i.e. the not intended use of the product, of locking cylinders or keys is for example:

2.1 applying an aid such as nails, pliers, key rings or similar objects to the key head to increase the torque. To ensure highest possible pick resistance, the keyway and shaft are expressly are made so slim as to ensure that the torque may only be transmitted directly by hand on the key head.

2.2 using the key as handle to move the door. The key is not a suitable means to substitute the fittings (knob, handle, etc.) on doors.

2.3 operating the locking cylinder with an incorrect, bent or damaged key.

2.4 trying to operate the locking cylinder with opening tools, aids or non-original duplicate keys.

2.5 applying foreign objects in the keyway or on the key or not adhering to the care instructions.

Product Features

3. As far as the product features are not specifically defined in our catalogues, brochures, specifications etc., the requirements for single locking cylinders shall be agreed in consultation with DOM. The standard DIN 18252 “Profile cylinders for door locks” is used as a reference. It defines basic and supplementary requirements for profile cylinders with one line of pin tumblers. The content of this standard is to be applied to other locking cylinders respectively. The suitability of a locking cylinder for an intended use depends i.a. on how often it is operated, how it is operated, the environmental conditions and whether care is correctly applied. Locking cylinders and keys shall be replaced as soon as the key, despite regular lubrication, may not be inserted or withdrawn as usual.

Product Maintenance

4.Locking cylinders shall be lubricated with the recommended lubricant at least twice a year or more often depending on use. As a general rule, DOM locking cylinders must not be oiled. Only cleaning agents without corrosive ingredients (e. g. DOM service spray) shall be used.

Duty to inform and Instruct

5. To comply with the duty to inform and instruct in accordance with product liability legislation, the following papers and services are available to specialised retailers, key service providers, architects, planners, advising institutions, processors or users:

  • Catalogues, leaflets
  • Tender texts, offer documents, locking schemes
  • DIN 18252 (exclusive sale by Beuth Verlag)
  • Instructions on installation, operation and care
  • Consultation from DOM or the field service.

To choose a locking cylinder as well as for installation, operation and care:

5.1 architects, planners and advising institutions are obliged to request and observe all necessary product information from DOM.

5.2 specialised retailers are obliged to observe product information and information stated in price lists and in particular to request all necessary instructions from DOM and pass them on to the user.

5.3 processors are obliged to observe all product information and in particular to request operational and care instructions from DOM and to pass these on to the customer.

Please Note:

Guidelines and product liability provisions applicable outside of Germany may differ from those applicable in Germany. The customer should therefore observe the information given on the installation and application of DOM products and whether guidelines generally corresponding to German DIN standards also exist his country and to determine the product liability he would have to assume in that country if he were to supply products.
