Your score for Credit for Dispatch Circuits (CDC) is influenced by monitoring the integrity of <br /> the primary dispatch circuit. There are up to 1.5 points available for this Item. Monitoring for <br /> integrity involves installing automatic systems that will detect faults and failures and send <br /> visual and audible indications to appropriate communications center (or dispatch center) <br /> personnel. ISO uses NFPA 1221 to guide the evaluation of this item. <br /> Additional points are available for dispatch recording facilities at the Communication Center. <br /> All alarms that are transmitted over the required dispatch circuits need to be automatically <br /> recorded (including the dates and times of transmission) to earn the maximum points in this <br /> item. <br /> ISO's evaluation includes a review of the communication system's emergency power <br /> supplies. To receive maximum credit, two sources of power need to be provided for the <br /> _ operation of the communications network including dispatch circuits and its related support <br /> systems and equipment. A common arrangement is to have the primary power come from a <br /> utility distribution system and a secondary power source from an automatic starting <br /> emergency engine-generator and/or an Uninterruptible Power Supply (UPS) and Battery <br /> System—(SEPSS-Stored Emergency Power Supply Systems). <br /> To determine the score for Item 432, four sub items (Item 431.A, Item 431.B, Item 431.0 and <br /> Item 431.D)needed to be evaluated. The criterion is as follows: <br /> CISO Properties,Inc..2007 Page 14 <br /> 5— <br />
