– 38 –Using A Non-Ademco AudioAlarm Verification (AAV) UnitIf you prefer to use another manufacturer’s AAV unit in place of the Ademco VIMunit, contact the manufacturer for information regarding the wiring of their unit tothe VISTA-40. When using another manufacturer’s AAV unit, see Notes below.Some AAV modules allow remote triggering by ring detection at the alarminstallation. Please be advised that if this option is selected, it may defeat modemdownload and 4285 phone module remote access capability. To prevent this,disable the remote AAV module trigger option. The control also requires that theAAV module trigger type is falling edge.IMPORTANT NOTES:• 685 Receiver software must be rev. 4.6 or higher. Earlier versions will not holdthe phone line connection.• Field 1*60 must be set for "1."Note: When this field is set to “1”, zone 5 can no longer be used as aprotection zone.The purpose of zone 5 is to silence the sounders on the control when anopen circuit condition occurs, signalling the start of an AAV session. The opencircuit must be triggered by the AAV module (i.e., a relay). Contact the AAVmodule’s manufacturer for specific details.• Zone 5 must be assigned a response type 10.• Field 1*46 must be set for “3” if the AAV unit requires a trigger. See “Using ATrigger To Activate Another Manufacturer’s AAV Unit” in the VOLTAGETRIGGER (Connector J7) in Section 5 previously.• If using a relay, such as the Ademco 4204, select “60” for System Operation,(see “Relay Programming” in Section 4. PROGRAMMING WITH #93MENU MODE).• Contact ID code for "listen-in to follow" is "606."• Contact ID (field *45 = 1) is the only reporting format that will send a "listen-in tofollow" message.
