Mar 07, 2017 VISTA-15p, VISTA-20P, installation Instructions The installation of smoke detectors in kitchens, attics (finished or unfinished), or in Ademco Contact ID® This manual applies to the following controls: VISTA-20P, VISTA-20PS, VISTA-20PCN.
Check out my page to find free installation and programming manuals for the Ademco Vista 20P as well as other brands of alarm panel.See this page for helpAdemco Vista 20P Terminal Connections 1 & 2 - AC TerminalsThe Ademco Vista 20P is powered by alow-voltage transformer supplying 16-18 volts AC. Connect each lead of a2-conductor wire to these terminals.
Since this is alternating current,you don’t need to worry about polarity.Be careful not to allow the leads from the transformer touch each otherwhile the unit is plugged in! Shorting out the transformer can easilyblow its internal fuse, turning it into a paperweight. While makingconnections, either leave the transformer unplugged, or keep the wiresseparated. 3 & 4 - Siren Output12-volts DC output, 2-amps maximumcurrent. This can be used for sirens, bells, strobes, or other devicesup to the rated output.The Ademco Vista 20P has the ability to supervise the bell connection,so you’ll get a trouble beeping at the keypad if the siren wire is cut.To enable this feature, cut the red jumper on the circuit board; it’slocated just above the terminal strip on the left end. 4 & 5 - Auxiliary Power (Aux Power)These terminals supply12-volt power to operate keypads, zone expanders, motion detectors, andother devices. Terminal 5 is positive, terminal 4 is negative.The maximum current available for all keypads and detection devices is 600mA.
If you need more than this, you can add a supplemental power supply. Preferably, this extra power supply would have its own battery backup, so it will continue to work during a power outage. If this isn't possible, make sure at least one keypad is connected to the Vista 20P's own power terminals.If you have many devices to connect, you’ll soon have trouble fittingthem all under the screw terminals. To fix this issue, connect a singleshort pigtail of 18-gauge wire to each terminal, preferably using redfor positive and black for negative.
Then, connect the necessary wiringto the appropriate pigtails using wire nuts. 6 & 7 – DataConnect data leads from keypads, zone expanders,or other data devices. Include at least one Ademco 6160 keypad to makeadvanced programming easier. Color code for typical 4-conductor connection:Red = +Power Black = -Power Green = Data terminal 6 Yellow = Data terminal 7The typical wiring used for any devices requiring data, such as keypads,is 4-conductor jacketed cable.

This cable is usually manufactured withthe colors red, black, green, and yellow (or white) for the individualwire insulation. This makes it easy to keep track of the power and datapairs, as well as the polarity of each.Ademco deserves extra credit for designating these terminals by color,rather than by “in” and “out”. Doing so simplifies wiring, since “green”at the panel end is the same as “green” at each device. The same istrue for the “yellow” data lead.

A minor point, but I welcome anythingthat saves time and confusion!To make fast programming changes, you can temporarily connect a 6160 keypad to a panel using this Terminals 8-20, Zones 1-8The Ademco Vista 20P has the capacityfor 8 on-board zones using basic connections. Each zone uses a 2,000-ohm(2K ohm) end-of-line resistor, which can be located at the alarmcontact or inside the panel.Zone doubling is an optional connection scheme that this panel supports; it adds 7 morehardwired zones to panel with no additional hardware.
This hookup arrangement is a bit moreadvanced, so I’ll cover it in a separate article.Zone 1, terminals 8(+) & 9(-), can be used for 2-wire smokedetectors. This allows the addition of fire protection to the panelwithout any extra modules or equipment, other than the smoke detectorsthemselves.
Up to (16) 2-wire smoke detectors can be used on zone 1 (Up to (10) forESL detectors with the “clean me” option enabled). Check the detectorspecifications to be sure they have a compatibility identifier of “A”.If you’re installing any 2-wire smokes, place the end-of-line resistor(EOLR) across the terminals of the last smoke detector in the run. Thisprovides a supervision alert from the keypads in case of a damaged firewire. Fire zones use “normally open” type loops, so the EOLR always goesacross the loop.
The Ademco Vista 20P also supports 4-wire smoke alarms, but a relay willneed to be added. This is to allow the panel to switch off power to thesmokes during a “smoke detector reset” command.For more details on wiring smoke detectors, see:Zones 2-8, Standard Burglary Zones Looking at the wiring diagram,zones 1 & 2 each have dedicated terminals for the “Hi” (+) and “Lo”(-) sides of their loops.
Check my drivers license number online. Zones 3 through 8 share their “Lo” sides inpairs. This is referred to as a “common negative” connection scheme, andis quite common in alarm panel design.
This is done mainly to simplifythe layout of the control board, as well as to save space. Burglary zones use “normally closed” loops, so always connect the EOLR in series with the loop.Note that the Ademco Vista 20P, like many other panels, can beprogrammed to not use end-of-line resistors on burglary zones. Thisoption simplifies wiring, and cleans up the panel a bit. Telephone Wiring, Terminals 21-24Connect the flying leads of anRJ-31X cord to the terminals as shown. The Ademco Vista 20P diagraminside the lid indicates the standard colors for each screw terminal,making things easy.When wiring the RJ31X jack, be sure the pair of wires feeding phone linein to the jack goes to the red and green screw leads. The pair sendingdial tone back to the premise phones should connect to the opposite pairof terminals, colored brown and gray.If these wires are hooked up backwards, the panel will seize the wrongside of the telephone feed.
This will kill dial tone to the housephones, but the panel won’t be able to send any signals to the centralstation. Earth Ground, Terminal 25The main purpose of an earth groundconnection on alarm panels is to provide lightning protection. The ideais that a voltage surge will tend to travel across spark gaps and otherprotective devices built into the circuit board, trying to reach groundpotential.It may be somewhat difficult to find a “good” earth ground, for a couple of reasons:. Some homes are built with plastic water lines coming from the street,changing to copper pipe just a few feet before entering the structure.Connecting to these pipes won’t give very good grounding, especially indry soil. House wiring grounds can also be a source of electrical noise, due todimmers and other devices. This noise can sometimes cause problems withan alarm panel, though it’s rare in my experience.The bottom line: If you happen to have a convenient earth ground nearthe alarm panel, go ahead and connect to it. If not, don’t sweat it.
TheAdemco Vista 20P has very good built-in lightning protection, evenwithout an earth ground connection.See why a Vista 20P is such a good choice for the average-size home.More information on.See a similar system made by GE Interlogix, theIf you have an older Ademco system that's starting to have problems, you may be thinking about replacing it.
