VISTA-15P/20P/SIA Installation and Setup Guide8Mounting and Wiring the Control (Continued)Hardwire Zones and Zone ExpansionHardwire Zones Normally Open Zones/ N.O. EOLR Zones1. Connect open circuit devices in parallel across the loop; for EOLR zones, connect theEOLR across the loop wires at the last device.2. Enable normally open/EOLR zones using Zone Programming mode, “Hardwire Type”prompt.Normally Closed Zones/ N.C. EOLR Zones1. Connect closed circuit devices in series in the high (+) side of the loop; for EOLR zones,connect the EOLR in series following the last device.2. Enable normally closed/EOLR zones using Zone Programming mode, “Hardwire Type”prompt.End of Line Resistor (EOLR) Notes If the EOLR is not at the end of the loop, the zone is not properly supervised and thesystem may not respond to an “open” on the zone. Zone 1 is intended for EOLR only.UL For UL commercial burglar alarm installations, use EOLR zones.Double-Balanced Zones(V20P only)Connect as shown below (resistor provided forone device).IMPORTANT: Double-balanced zones providezone tamper protection, and should be used asburglary zones only.Do not use double-balanced zones as firezones.Fig. 7. Typical Double Balanced ZonesZone Doubling(V20P only)This feature provides two hardwired normallyclosed zones for each standard hardwired zoneconnected to the control’s terminals (but doesnot increase the total number of zonessupported by the control). If enabled (ZoneProgramming mode, “Hardwire Type” prompt,option “3”), hardwire zones are automaticallypaired as shown in the table. Connect asshown (resistors supplied; use 3k and 6.2k 5%,1/4W or bigger resistors). Do not use zone doubling for fire zones.NOTE: A short across the EOL (i.e., atterminal) on either zone of a zone-doubled pairor on a double-balanced zone causes a tampercondition (displayed as CHECK plus zonenumbers).Fig. 8. Typical Zone Doubling WiringZone Doubling TableZone Paired with zone2 103 114 125 136 147 158 16NOTE: Zone numbers used for zone doublingcannot be used for anything else (ex. cannotbe used for 4219 zones)Smoke Detectors 1. Connect up to 16 (10, if “clean me” option used) 2-wire smoke detectors across zone 1terminals 8 (+) and 9 (-) as shown in the Summary of Connections diagram at the backthis manual. Observe proper polarity when connecting the detectors.2. Connect an EOL resistor across the loop wires at the last detector.3. Connect 4-wire smoke detectors (number of detectors depends on detector current draw)to any zone from 2-8 as shown in Figures 9a and 9b (on next page).Power Reset: This control does not automatically reset power to 4-wire smoke detectorzones, so you must use a relay (e.g., 4204, 4229), or on-board trigger to reset power(also required for fire verification). Do this by programming the designated relay/triggeras zone type 54 (fire zone reset); see On-Board Trigger section for other information.NOTE: Maximum current on trigger 17 is 100mA.
