Installer Menu Options i-on RangePage 86time the control unit will not set the system. The control unit will log the failure as “set fail”.At the same time the control unit will activate any output programmed as type “Set Fail”.Note that if you assign zones the “Force Set Omit” attribute then the control unit will omitthose zones if they active during a scheduled setting event.Unsetting Events. When the control unit reaches the time programmed for an unsettingevent the control unit unsets all partitions programmed to unset. There are no specificwarning indications for partitions unset by a calendar event.Manual Setting/Unsetting and Calendar Sets. If a user sets a partition that is due to beset by a Calendar event, then the partition remains set when the calendar event time ispast. Likewise, if a user unsets a partition before a calendar event is due to unset thepartition then the partition remains unset. Manually setting and unsetting partitionscontrolled by Calendar Sets will not alter the times programmed in Calendar events.Restrictions on Calendar SetsPlease remember the following points when setting up events:1. You cannot program an event to change the system/partition directly from one part setlevel to another. You must program an event to unset the system/partition first, andanother event to set the system/partition to a different part set level. For example, if eventA part sets the system (or a partition) then you cannot program event B to full set thesystem. You must program event B to unset the system and then use event C to full setthe system.2. If you are unsetting a partition and setting the same partition again then you mustprogram the setting event to occur at least 10 minutes after the unsetting event.System OptionsThis section of the Installer Menu contains a series of options that affect the working of thealarm system as a whole.Note: The default settings for these options are compliant with EN50131, see page 33.Changes to some of the defaults may render the system non-compliant.Wired Zone Type30 40 50 160Normally the control unit asks you to select the zone wiring type when you power up a newinstallation for the first time, or when you restore the control unit to factory defaults (seepage 14). This sub-menu lets you change the zone wiring type for either the control unit orfor the whole system.Note: If an i-on16 has a KEY-KPZ01 connected and the keypad zones are enabled, thenthis menu item will appear in the installer menu.There are two options:PanelZonesThis option lets you change the zone wiring type for the control unit.All Zones This option lets you change the zone wiring type for the whole system.For both options the choices available are: 2k2/4k7. 1k0/1k0, 2k2/2k2, 4k7/4k7, 4-wire CC,or 2-wire CC.If you select “4 Wire CC” then i-onEX control units and/or expanders provide five wiredzones, The zones are numbered 1 to 5 on the control unit and e0 to e4 on the expander,
