D6600 | Operation and Installation Guide | 10.0 D6600 Operation16 Bosch Security Systems | 2/05 | 4998122704E9.2 Automation Link Monitoring (COM3)through CPU Programmable OutputPortsThe output connections on the I/O port have an opencollector transistor output that can activate an externalsounder or light if the automation system fails.Configure external devices using thespecifications listed in Table 8. Outputsare not verified by UL.Table 8: Terminator Card ConfigurationRadionics D6615 CPUTerminator CardBosch D6615 CPUTerminator CardSolid state output providesa current sink to common (-)Solid State output providesa current sink to common (-)Maximum load is 20 mA Maximum load is 75 mAVsat @ 1 mA = 0.5 VDC Vsat @ 10 mA = 0.5 VDCVsat @ 10 mA = 3.0 VDC Vsat @ 25 mA = 1.0 VDCMaximum voltage = 30 VDC Vsat @ 50 mA = 2.5 VDCMaximum voltage = 30 VDC10.0 D6600 Operation10.1 Process Flow10.1.1 Event DatabaseThe Event Database stores all trouble conditions andalarm messages that occur in the D6600. Themaximum number of events stored in the database is20000. If the automation system is not functioning, theD6600 does the following:• When receiving over telephone lines, the D6600stops answering and acknowledging calls at 19500.• When receiving over a network, the D6600 stopsacknowledging incoming events at 19000 becausethe communication is much faster.These limits provide a warning before the databasebecomes full.Under normal operation, when the database reachescapacity, the receiver drops the oldest event in thedatabase. This is typically known as First In, First Out(FIFO).When using the D6600 keypad, an authorized user canview these messages through the menu. To enter theEvent Database:1. D6600M/E2.
