• Is vandalism likely to be a problem by having equipment damaged.

• Volume of use combined with speed of operation
  
• Transaction recording (on-line/off-line)
  
• Expandability
  
• Programming ease

The initial specification of a system should take account of the design criteria, ease of use, the quality of the equipment provided, a high standard of appearance of the installation, compatability of the equipment and possible future extension of the system. In all cases, the power supplies, both mains and standby should have 30% spare capacity when the system is installed.

When a system is designed for use in a new building, it is essential to involve the building designers with a view to producing a system which has a minimum disruptive effect on the finished building.
