M/E Roundtable (Continued from page 17) GIANNINI: Again, experienced qualified systems integrators have the abilities to provide the appropriate level of programming, together with proven testing protocols, for the sequence of operations needed by the customer. Some of these programs and tests are code driven, and some are driven by the specific needs of the customer. The more experienced systems integrators have knowledge and skills in both of these areas. CONVERY: The sequence of operation for an integrated fire/security system is written and tested the same as other building systems interact with the integrated fire/security system. Operating procedures are developed for each mode of the combined system. Codes and standards define priority reporting. Testing of all components should be conducted to ensure proper installation and function. Because the systems are integrated there may be some redundancy, which can provide time and cost savings. CASAMASSIMA: Historically, authorities having jurisdiction (AHJs) have required that the two systems be tested independently from each other and that security should not interfere with the control aspects of the fire system. CSE: What do you think is the most significant integration challenge and what is a good approach for dealing with it? CASAMASSIMA: The most significant challenge ahead is to integrate the requirements of mass notification with the existing infrastructure. Most networks are control-type functions, so adding an audio component is very challenging. Specifiers should ensure whatever systems they are specifying can support mass notification, both now and as an add-on in the future. GIANNINI: The most significant challenge involves the integration of security technologies that must communicate over existing customer network infrastructures. The use of software development kits has become more common. Having personnel who can develop and write the appropriate scripts/source code for these kits is an important first step. GRILL: Timing of completion can be the most significant challenge. When dealing with life-safety systems, obtaining a temporary certificate of occupancy (TCO) to allow for move in, etc. can be critical. Many AHJs will grant a TCO if a ventilation or security system isn’t completed. However, they won’t grant a TCO if your life safety systems aren’t operational. The design of the systems needs to take this into consideration. It often is impossible to adequately test the life safety function of a fully integrated system without the entire system being complete. CONVERY: One of the most significant challenges is coordination between disciplines. Inherently, security systems are meant to fail secure while fire alarm systems are meant to fail safe. Security system professionals must be careful not to violate life safety code requirements. A close working relationship between security system professionals and fire protection professionals help alleviate this challenge. C S E : Te c h n olo g y i s c o n st a nt ly evolvin g. H ow c an integ ratio n efforts keep up? GRILL: First you have to try to define integration. In my opinion, if your overall fire protection approach isn’t integrated, the owner will not receive the best value or best technical solutions. This doesn’t necessarily mean that all of the low voltage systems are driven by a common control panel. But it does mean that they all have been considered and specified so that they will work together. Getting back to the question, there needs to be continual interaction between suppliers of the various types of systems to ensure that equipment can function appropriately together and not interfere with critical functions. The importance of this interaction and coordination is going to increase as more functions, such as mass notification, are integrated with fire alarm and other building systems.
