Installing and Maintaining i-on10Page 14Detector (zone) wiring typesBefore installation, you need to choose the wiring type (method) to use for any wireddetectors: Fully-Supervised Loop (FSL), 4-wire Closed Circuit (CC), or 2-wire CC, asdescribed below. You must use the same wiring type for all wired detectors.You will need to ensure that all detectors are wired correctly and that you select the defaultwiring type during the initial power-up procedure.Fully Supervised Loop (FSL)This uses a single pair of wires for each detector, with resistors at the end of the line andacross the alarm contact (Figure 2). The resistors allow the system to monitor for short-circuit or open-circuit conditions to guard against cable tampering.The End-of-Line (EOL) and alarm contact resistors can be any of the following values(respectively): 2k2 and 4k7, 1k and 1k, 2k2 and 2k2, or 4k7 and 4k7. The resistance bandsfor FSL are as shown in Table 4.Figure 2.
