36 I ICT TODAY Access Control Integration Some doors may include many of the previously mentioned design considerations, and a sequence of operations must be developed when multiple systems are active at the same time. While cabling standards ensure interoperability between multiple vendor components, the same is not true for ACS. ACS include components that do not work together, even when using industry standard protocols for transmission. A complete system solution is required to ensure functionality and compatibility (Figure 4). Similar to other technology-based industries, manufacturers of access control systems have designated dealers and business alliances with systems integrators and security contractors. Manufacturers often limit the number of dealers in a particular market. Vendors who are not authorized dealers for a specific system cannot procure or provide a full warranty on the hard- FIGURE 4: Since ACS include incompatible components, a complete solution, as shown, is needed to ensure compatibility and functionality.

Consideration and planning of the systems integration is essential during design to ensure various integrated systems can be properly maintained and tested throughout the life cycle of the building. The basis of design should be frequently reviewed and updated with changes in design as the project advances. 4. DEVELOPMENT AND UTILIZATION OF A COMMISSIONING PLAN Acceptance test criteria should be developed by the ESS systems designer in concert with the architect and door hardware consultant. These criteria should include the project design team's intent and its anticipated use by occupants. The commissioning plan should be updated during each phase of the project so that it remains correct and contains the required testing. The commissioning plan should include the following information: • General project information • Commissioning scope and overview of the project's security • Commissioning team members, roles, and responsibilities • Process tasks and commissioning activities through all phases • Commissioning schedule • Commissioning process documentation and deliverables • Testing procedures, including integrated testing • Recommended training ware. When specifying a manufacturer, consideration should be given to the integrator in the project area and the integrator's number of trained engineers, number of similar installations, and verifiable references. Inspection, testing, and operation and maintenance requirements for integrated systems are often over- looked during the design phase, thereby adversely affecting the construction phase and construction
