Wire detectors to zones Galaxy Flex Installer Manual18Figure 4 Option 12 - Double balanced 1k fault/mask monitoring wiringWhen this wiring mode is used, ensure only one detector is set to report fault conditions, andlimit the number of detectors or contacts of any type to a maximum of 2.Note: The recommended maximum cable run from a zone to a detector is 500 metres in allother configurations.In end-of-line mode use the wiring shown in Figure 5.Figure 5 Option 10 - End of Line Zone/Detector wiringMultiple detector wiringMultiple detectors can be wired into a single zone when using preset 1 as shown in Figure 6.The maximum number of detectors that can be connected to a single zone is ten.Figure 6 Zone to multiple detector wiringWire keyswitchesLatching or spring loaded keyswitches can be used to set and unset the panel. To programkeyswitches, refer to Program Zones [52].If the keyswitch latches, the transition from 1 kΩ to 2 kΩ initiates the setting procedure ofan unset system, the transition from 2 kΩ to 1 kΩ instantly unsets a set system. If the systemis already set, then the transition from 1 kΩ to 2 kΩ has no effect. If the system is unset, thetransition from 2 kΩ to 1 kΩ has no effect. This is programmed as a Keyswitch in theProgram Zones [52] option.
