The Honeywell 1361 is an AC transformer with an output voltage of 16.5VAC and a power rating of 40VA. The 1361 transformer is a step down converter that takes the 110VAC voltage from your standard wall outlet and converts it into the 16.5VAC voltage used by most Honeywell alarm control panels and some AlarmNet alarm monitoring communicators.

The 1361 AC transformer is included with the VISTA-21iP internet alarm control panel and the VISTA-128BPT and VISTA-250BPT commercial alarm control panels. The transformer is also included with the AlarmNet GSMV cellular alarm communicator and the iGSMV dual path alarm communicator. The Honeywell 1361 has (2) screw terminals on the back side of the transformer. After purchasing the 1361 AC transformer, you will need to purchase alarm wire separately as it does not come with the wire needed to connect the transformer to whichever device it will be powering. We recommend using (2) conductor #22 gauge alarm wire for most installations. You can use #22 gauge as long as the wired connection between the transformer and the device being powered is less than 25’. For connections between 25’ and 50’, you should use #20 gauge wire. For connections 50-100’, you should use #18 gauge wire and if you have a wired connection that is 100-250’, you should use #16 gauge wire. Higher gauged wire is thinner than lower gauges. Longer wired connections require thicker wire. You can normally locate your alarm control panel or AlarmNet alarm communicator within 25’ of an outlet and that is why #22 gauge wire is recommended.

It is very important that you do not plug the Honeywell 1361 transformer into a wall outlet until after it has been wired to its device. If you do plug the transformer in before wiring it to its device, you can easily blow the fuse within the transformer and you may even damage your alarm control panel or your alarm communicator. Once a transformers fuse is blown it cannot be replaced or fixed. Alarm Grid does not offer refunds or exchanges on transformers so you will need to purchase a new 1361 if you accidentally damage yours by wiring it incorrectly. As long as you always make your wire connections with the 1361 transformer unplugged, you should not have an issue with blown fuses.

The Honeywell 1361 is unique because it can be used to power a VISTA-10P, VISTA-15P or VISTA-20P alarm control panel along with an AlarmNet GSMV or iGSMV alarm monitoring communicator. Normally, you would need a transformer for your control panel and a separate transformer for your alarm communicator. Depending on your installation location, you may only have one available plug to plug-in the transformers. Therefore, using the shared installation will prevent you from having to run a long wire connection to another outlet.

When using a single 1361 AC transformer to power an alarm control panel and an AlarmNet alarm communicator, you should first wire the transformer to the AC terminals of the control panel. Next, use a separate (2) conductor wire to connect the power terminals of the AlarmNet alarm communicator to the same AC terminals on the control panel. When completed, you will have a set of wires coming from the communicator and a set of wires coming from the transformer. There will be (2) red conductors under one AC terminal and (2) black conductors under the other AC terminal on the alarm control panel. You can then plug the transformer into your 110VAC unswitched wall outlet to power up both devices.

That is a very heavy transformer. It comes with a screw to screw it into the center of the receptacle cover. But there is still a chance that it’ll be so heavy it’ll pull itself out of the wall.
Can this transformer be plugged into an outlet that is in the ceiling? Meaning the outlet is parallel to the floor, not on a wall. I know some transformers are not designed to be used in this configuration and didn't know if this was one of them. I need to replace the power supply on my alarm system and the receptacle that it is powered from is on the ceiling pointing towards the floor.
As long as the outlet you’re plugging the 1361-GT into has a good earth ground connection, you can leave the ground terminal on the transformer unused.
I would like to use the 1361-GT (three-prong, with three-scew-terminals) to replace an existing (failed) 1361 (two-prong, with two-screw-terminals). The existing alarm control has a separate ground wire to building earth ground. Can I connect the 1361-GT AC terminals to the alarm control and leave the GND terminal empty, or should I move the building earth ground wire to the 1361-GT GND terminal?
No, you can do it that way, though you'll probably use more wire in that scenario.
Does it create any problem running two sets of conductor wire from the 1361-GT transformer, one to the panel and the other to the communicator? My prior alarm company had it wired up like that.
Hi David, unfortunately you will need one transformer for each device.
Would this support enough current to power a Vista 20p <i>and</i> an Altronix SMP3 external power supply?
If you run into any issues email us here at We do offering monitoring plans here at
I'm running 2 motions, a door contact, an led, a take 345, and a siren. I'd be shocked if it was drawing more than an amp. I'm going to get rid of the Vista panel and just use the 2 amp power supply to power the equipment I just mentioned.
Also, if you need a power supply, you’re already overdrawing the VISTA-20P's available power output, so why tax the transformer further by trying to share it with another separate device.
Hi Dennis, The system transformer is designed to provide the appropriate power the VISTA-20P will need and it's a different transformer than the one the AD12612 calls for (the 20P's ship with a 1321 while the AD12612 should use the 1361). While a 1361 would work for a VISTA-20P, it wouldn't work to power both the 20P and the AD12612 due to the higher overall power draw that setup would entail. Are you out of available outlets in the area or do you just not want to have two plugged in transformers if you can avoid it? Also, did you see we offer no-contract alarm monitoring plans online at We fully support the 2Gig systems and service and would love to help you out if you're interested. If you are, please email or give us a call M-F 9-8 EST at 888-818-7728.
I have a follow-up question to this. If you took over a Vista 20P with a Take345 module and you are no longer using the Vista as the main system, but more as a bus bar to power hardwired motions, can you: 1. use the same transformer to power the Vista and an aux power supply, or 2. Use terminals 1 and 2 on the Vista to power the aux power supply (with the wires from the transformer already connected to these terminals)? I'm now using a 2GIG GC2 with a separate transformer than the one powering the old Vista panel. Is the reason you're saying not to power both devices (Vista and aux power supply) from a common transformer a reliability issue for your main panel, or is it because it will cause damage to the equipment? Thanks
Hi Jim, we do not support ring but they do operate on high voltage power 110VAC directly from the electrical panel. Please contact Ring technical support for specifications. Hope that helps :)
Opposite question. I purchased 3 of the Ring mount spot light cams during all the holiday sales that are all110V cameras to replace the existing Honeywell cameras that require the transformer. If I read correctly this would this be a simple R&R?
Hi Matthew, yes, the 1361-GT includes both a terminal for an Earth Ground (so 3 terminals total) and a 3rd prong for the ground connection in the outlet. This picture is of the old 1361, which included neither of these things. If you order this, you will get the transformer with the ground prong and the ground terminal. This is just an older picture, and we're working on getting it updated.
Is this transformer truly only 2 pronged without a separate ground, as pictured? Or will the part that ships have a 3 pronged plug with 3 screw terminals including a middle ground terminal? I am asking because I have in my possession a 3 pronged Honeywell transformer that has the same 1361-GT model number (and I am using the ground). I also have an unlabeled (no printed model number) Honeywell transformer of similar size that is only 2 pronged (and also happens to be broken). I would prefer to buy another 3 pronged 1361-GT to replace my broken 2 pronged transformer. For this second transformer I don't *need* the ground terminal, but I prefer to have it for future flexibility.
Just like with a VISTA panel that takes AC input from the transformer (1321 or 1361) and then provides DC output for the connected devices (terminal 3 is the 2A DC positive output for sirens and terminal 5 is the 600mA DC positive output for the ECP devices like keypads, communicators, receivers etc), the AD12612 is a power supply for using a wired siren with the LYNX Touch systems. The AD12612 gets power from the AC transformer and puts out 1.2A of DC power for the connected devices. While the VISTA panel is listed compatible with both the 1321 and 1361, the AD12612 lists only the 1361 as compatible and therefore you should not try and re-purpose your old 1321 transformer for your AD12612.
The 1321 transformer supplies 25VA, or at least the one I have says so on the transformer. Both the 1321 and the 1361 supply 16.5VAC. The only difference I can tell is that the 1361 supplies 40VA, instead of the 1321, which supplies 25VA. If you are wanting to use a Lynx wireless control panel with an wired external siren, such as the Honeywell 748, which has a maximum draw of 1.2A, I would think that the 1321 would work fine. If you are using a Honeywell AD12612 power supply, which has a 1.2A output for the siren, but if your external siren draws more amperage, you would need a larger power supply, but in either case, I see no reason why the 1321 or the 1361 wouldn't work just fine, but please fell free to correct me if I am wrong.
The transformers cannot be combined in any way so I don't think there is a way to use the 1321 "with" the 1361. With that said, the 1321 performs the same operation as the 1361 except that it only supplies 16.5VA as opposed to 40VA.
I have an extra 1321 AC transformer. Can that be used with this?
No, you should use separate transformers for the panel and auxiliary power supply.
Can this transformer power both a Vista-20p panel and an auxiliary power supply (AD12612) at the same time?
Yes, you are correct in that the two AC terminals on the 1361-GT get connected to terminals 1 and 2 on the VISTA-21iP control panel. With AC connections, there's no polarity so it doesn't matter which AC terminals go to 1 or 2 as long as you have both connections. The GND terminal on the transformer would be used to wire to an "earth ground" such as a proper grounding rod or metal cold water pipe.
Two hopefully quick questions - I have the newer 1361-GT, which has three connections: the first and third one marked "AC" and the middle one marked "GND". I'm assuming the two marked "AC" get connected to terminals 1&2 on the Vista 21ip. Does it matter which "AC" connection gets connected to those terminals? And, what does the "GND" get connected to - the ground wire on the electrical outlet? Thanks.
The 6160RF draws up to 150mA and the non WIFI Tuxedo draws up to 260mA. The panel power output on terminal 5 is rated up to 600mA so I would think you don't need an auxiliary power supply unless you do choose to add the 2nd Tuxedo.
I am looking to get it ready to do the basic self monitoring to get clear out and sensor bugs. We are went on vacation and set it. We came back to tons of false alarm events. I have moved those sensors since though.
Is your system monitored currently?
Ok.. does the panel have enough power to run the two panels and two motions off term 4 & 5? I plan to add another tuxedo in the bedroom later but I think I will need an external power supply for that one.
If you are using a shared transformer for the panel and communicator, you can run a parallel connection from terminals 1 and 2 on the panel to 1 and 2 on the communicator. The other option is to run the communicator's transformer directly to 1 and 2 on the communicator and leave the panel's transformer connected to 1 and 2 on the panel. Either way you do it, you still need the connections from the communicator's terminal 3 to the panel's terminal 5 and the communicator's terminal 4 to the panel's terminal 4.
I double checked.. the panels are of 4&5 but the communicator is 1 & 2. I did notice that I did put the motions off 1&2 and they should be on 4&5.
Do I understand it right that you are running your power for your motions, keypads and communicator off the panel's terminals 1 and 2? If so, that is incorrect. Terminals 1 and 2 on the panel are for the AC input from the transformer. Powered devices (like keypads, communicators and 4-wire sensors) need to be powered from the DC output terminals which are 4 and 5.
So my project over the weekend was to add a dual communicator and 2 wired motion sensors. When I plugged everything backup, it fried my transformer. I ordered the 1361 and while waiting for it to come in, I saw a similar transformer at Frys (16.5 V, 40VA). I tried that one and it fried too in about 5 minutes. Do I really have too much load for the transformer? It is powering my Vista 20p, tuxedo non wifi panel, a 6160rf panel, igsm4v and two aurora motion sensors. The motions, panels and igsm are of term 1 & 2.
Thanks! :)
The system ships with a 16.5VAC, 40VA transformer so I would use that one if you could but the one you have should work as well.
I have a Honeywell Vista20P Panel...I have an Ademco N8167 Transformer (16.5 50VA) connected to the system. Is it ok to use the n8167 transformer with a Vista20P Panel?
