SPECIAL NOTE ABOUT THE PRODUCTS SHOWN ON THE WEBSITE AND IN THE PRINTED CATALOGUE: The product details illustrated represent ideal situations and are in-line with the respective guidelines for custody area design. However, if you have differing requirements our in-house design team, custodial equipment experts, and manufacturing division WILL be able to fulfill your needs. Call or email us to discuss your specific requirements.

Where product specifications indicate opening dimensions, these represent ideal sizes. The majority of Cell Security Limited products shown are custom made to suit new openings or existing situations.

Most products are detailed bolt-fixed into position after openings have been built. Experience has shown this installation method for doors is desirable as it guarantees alignment, satisfactory operation of the lock and correct panel and rebate tolerances are achieved. Additionally, the bolt-fix method allows products to be installed later in the project, thus reducing risk of damage.

A range of common door frame fixing arrangements are detailed here with the most suitable detail being selected depending on site conditions and circumstances.

Q. Are doors best built-in or bolted? A. Guidelines commonly indicate building in yet bolting has proved to be advantageous for reasons described above.

Q. What standard of masonry should I use for the walls?

A. It is very important that substantial solid masonry - 32 Newton bricks or 7 Newton blocks - should be used in the custody area and all areas and corridors where security doors may be installed.
Under no circumstances should hollow or perforated bricks be used. 1/2 brick or 100mm block is NOT suitable, with a minimum of 140 block recommended.

Q. I notice the catalogue shows a threshold set into the floor yet my openings have an existing floor I would prefer not to excavate.

A. Ideally a four sided frame is preferred but to avoid excavation of existing floors a three sided frame can be used.

Q. My Fire Officer insists that some custody doors give a fire rating.

A. Cell Security have received an assessment of fire resistance for 4 hours on our CS14 lightwight commercial door, and 1/2 hour on our CS20 steel clad timber door, for use in custody areas. This is in accordance with the integrity criterion of B.S.476 : Part 22 for fire attack from both sides.

Q. My Guidelines indicates that Teak should be used on the timber products. Is Teak still available?

A. Although guidelines often indicate teak it has proved impossible to obtain sufficient Teak to supply the volume of timber benches required. Alternatives to Teak are Iroko, Ash and Maple. As a further alternative Corian© can also be utilised.

Q. Do the products have to be the size as shown in the Cell Security catalogue? (NOTE: Printed Catalogue is available on request)

A. Sizes in the catalogue are ideal dimensions but doors and other products are made to measure and can be manufactured to suit existing opening sizes.

Q. Can Cell Security provide an installation service?

A. Yes, and this is probably the most desirable route for satisfactory installation. Exceptions are pre-cast concrete items which are built in to the walls and glazed concrete cell windows which due to their weight are best installed using on site lifting equipment more easily available to the main contractor than a sub contractor.

Q. I maintain an existing custody suite but I am not sure what upgrading facilities are available. Can Cell Security advise?

A. Yes, Cell Security will visit site and prepare a written report advising on the most appropriate upgrading to bring to current standards.

Q. Can I have my existing doors retained but fitted with new locks?

A. Yes, this is a common request and Cell Security can survey and advise, similarly any cell glasses or grilles can be upgraded.

Q. My custody area seems satisfactory but I am concerned about ligature risks and what can be done.

A. Cell Security can provide a survey and advise on any risks and suggest appropriate remedial work.

Q. Can Cell Security advise on suitable locking?

A. Cell Security will advise on the most appropriate lock type for each area.

Q. How can I determine what suiting I should use for the high security locks in the custody area?

A. Cell Security will advise and if required develop a suiting scheme to suit the project. Included in this scheme will be advice on keys.

Q. Can my new door have a lock which suites with the existing locks?

A. Maybe. If existing locks are modern this will be possible, alternatives include a) New locks to be made to suite with old locks. b) New lock provided and old locks have new levers fitted to suit new lock. c) New levers not possible so existing doors have locks exchanged for new locks.

Q. What are delivery periods for Cell Security products?

A. Some standard items are held in stock but most are made to measure and are on a 6 weeks delivery depending upon the volume of the contract.

Q. Do Cell Security provide drawings for approval?

A. Yes, it is important that drawings are produced and approved so all parties are aware of what is being provided.

Q. Do Cell Security make to agreed sizes or site check?

A. Either. If time allows it is better to check site openings and manufacture to site sizes. Otherwise drawings will be prepared and openings must be produced to match the openings. If Cell Security provide installation they will check all openings if others provide installation site checking will be their responsibility.

Q. When is the best time for installation?

A. On a new build situation the later in the project the better. Early installation makes the products vulnerable to damage and impedes progress on the site as fitted doors may prove to be an inconvenience on a building site. Ideally doors should be installed two weeks before render is applied and floor screed is laid.
