Building Size and Future Expansion

How big is the building? How many doors require locking? How many doors will require locks in the future? Building size and future building size will help you to consider system capacity now and what it may be in the future.

Is it a new build, extension or refurbishment?

What locks have or will be fitted? What profile of cylinder is required, euro, UK oval, Scandinavian oval etc? Understanding if the system is being supplied into a new or existing system could mean a difference in locks and therefore a difference in cylinder profile and type.

Are the external doors and locks to be incorporated in the system?
