Description

The Honeywell AD12612 is an auxiliary power supply that can provide continuous 6VDC or 12VDC, 1.2A power output to security system devices that require supplementary power. The power supply also has a charging circuit which can be used to charge a backup battery like the Ultratech 1240.

Honeywell alarm control panels have an auxiliary output that can supply a limited amount of power to devices that require power such as alarm keypads, AlarmNet alarm monitoring communicators, wireless receivers, wired motion detectors and wired glass break detectors. When you connect devices to the ECP terminals of a Honeywell VISTA Series alarm control panel you must be sure to not exceed the maximum auxiliary output. A residential VISTA-20P or VISTA-21iP alarm control panel auxiliary power output is 600mA and a VISTA-128BPT or VISTA-250BPT commercial alarm control panel provides up to 750mA of supplementary power. If the power load from all of your wired devices exceeds the maximum auxiliary power output of your alarm control panel, you will need to connect some of the devices to an auxiliary power supply like the Honeywell AD12612.

The AD12612 power supply is set up by default to provide 12VDC, 1.2A of power output but you can move the jumper over to the right (2) pins if you want to use the power supply to provide 6VDC, 1.2A power output instead. Underwriters Laboratories (UL) has not approved the use of an AD12612 power supply when supplying 6VDC of output power and nearly all alarm devices require 12VDC of auxiliary power so you shouldn’t need to change the jumper. When using the 12VDC mode, you should use the Honeywell 1361 AC transformer and you should use the Honeywell 1322/TF3 transformer if you are going to use the 6VDC power output option. By connecting either of these AC transformers, the Honeywell AD12612 will be able to push the 1.2A of 6VDC or 12VDC supplementary power to the connected devices.

Unless you also connect a 12VDC, 4AH sealed lead-acid backup battery to the AD12612 power supply, your connected devices will not work during a power outage. The power supply charging circuit has a charging voltage of 13.6VDC and a maximum charging current of 130mA. If using a backup battery with your AD12612, you must subtract 130mA of power output from the maximum 1.2A output when calculating the available load for your connected devices. If you lose power or the AC transformer fails, the backup battery will provide (24) hours of standby time at a 200mA drain level. The battery is protected by a PTC device for overcurrent situations and the PTC device automatically resets once the overcurrent situation is resolved.

The Honeywell AD12612 is the recommended auxiliary power supply to power the Tuxedo Touch and Tuxedo Touch WIFI graphic touchscreen keypads. Simply connect the (2) ECP terminal wires for power from the Tuxedo keypad to the (+) and (-) ‘DC OUTPUT’ terminals on the AD12612. You should also connect a black wire jumper between the (-) ‘DC OUTPUT’ terminal on your power supply and the ‘AUX -’ ECP terminal on your alarm control panel.

The AD12612 power supply is also recommended when adding an external sounder to an L5100 LYNX Touch wireless alarm control panel. As the L5100 LYNX Touch doesn’t have an alarm output, it cannot supply the auxiliary power needed to drive an external alarm siren. Therefore, you need to connect an AD12612 to a Honeywell 5800RL wireless relay or a wired sensitive relay like the Altronix RBSNTTL sensitive relay and also to whichever wired sirens you’d like to use with your LYNX Touch control panel. The LYNX Touch must then be programmed to activate the relay on each alarm so that the power supply drives power out to the connected sirens.

Following up to post the solution in case someone else encounters the same problem. After it happened to me the second time (and police dispatched), I dug a bit deeper and found the culprit. Ultimately, I discovered that my RF Repeater (5800RP) has an internal backup battery. I had forgotten that I had the repeater and never knew it had an internal battery. After 6 years, the battery had begun to weaken. Apparently, the system interpreted it as a keypad low batt, but all my keypads are wired so I knew it must be something else. I contributed to the problem because I failed to set up an RF zone for the low battery condition when I installed the repeater. For reasons I don't understand, the condition was associated with my duress zone. So the solution required 2 steps... Replacing the Ni-MH backup battery in the RF Repeater and creating a new zone for handling the low batt condition (as described in the 5800RP documentation that I should have read more carefully 6 years ago). I actually created the zone before replacing the battery to make sure this would handle the condition (in a manner more desirable than having the police visit!). I immediately got a message that the RF Repeater battery was low. Problem solved.
Hello Steve, Yeahs it's hard to say. I've never seen a low battery cause a panic, but I have seen keypad bus issues cause panics. Also to clear a low battery check this out, it requires a little more effort, unfortunately. https://www.alarmgrid.com/faq/how-do-i-clear-a-low-battery-in-my-honeywell-vista-p-series-pane
I've been using an aux power supply (AD12612) with my Vista 20p for several years with no problem. Tonight. my system inexplicably registered a silent panic alarm on its own. I then discovered that my keypads were displaying KYBD LO BAT (with no zone number). All of my keypads are wired, however I do have several wireless sensors--all seem fine. I began checking voltages and both transformers (main board and the AD12612) seem to be functioning normally. I disconnected the batteries and discovered that the 4ah battery connected to the AD12612 was outputting only 10.5VDC. I have already ordered a replacement. The backlighting on my keypads seemed dimmer than usual while the KYBD LO BAT was displayed. I couldn't clear the KYBD LO BAT fault by entering *0. I had to completely power down and disconnect the main panel's battery to reset the system. Everything appears to be okay now (except I have to replace the aux battery). My theory is that the battery developed an internal short of some kind that really confused the system. Completely powering down must have cleared it. However I'm still mystified by the silent panic. Any thoughts?
Hey Joe, Unfortunately we do not have any "supervised dc power supplies" available that would be able to trigger a signal to the panel.
Thanks Darrell, is there an alternative aux power supply for the Vista 20P that can report battery trouble?
Hey Joe, It will not as there is not a way to supervise the A12612 so it sends a signal to the panel in case of low battery since it is a stand alone part within the system.
My Vista 20P has a 7AH battery connected to it. It also has an AD12612 installed with a 7AH battery connected to it as well. If the battery connected to the AD12612 fails, will the alarm panel report battery trouble?
Unfortunately, Honeywell/Reside doesn't provide PCB level support of their products, and we don't have that information, so I can't be of any help to you with this question. Good luck, though!
We actually have a nice FAQ that details how you can do this at: https://www.alarmgrid.com/faq/how-do-i-add-a-siren-to-a-honeywell-vista-system-using-a-power-s but it references a different relay option than the 4204. We can certainly help you with that as well but are you able to email us at support@alarmgrid.com so we can discuss in our ticketing system?
Hi, i would like to add a siren that would take me over the 2A limit. I have an AD12612 and a 4204 installed. Can you please provide instructions on how to wire the additional siren and any additional programming that would be required. Thanks.

Hi Ciara - Can you help with the following question. I have 2 Supco TA2 dry contact temperature alarms that I am using to monitor temperature in a walk-in freezer and walk-in Fridge. I want to hard wire to Zone 2 & 3 on my Vista 21IP. The Supco's are set for a Normal Open, close on temp rise above set point. Monitoring co. wants a resistive load in parallel with temp monitor but did not indicate value. Any guidance on R value I should use. 1, 100, 1K etc. I have some 3k and 6.2 k Ohm in stock. I'm assuming they want to see some load for normal operating condition and then short on alarm will be the trigger. Any guidence is greatly appreciated. Thanks Mark
You're welcome. Have a wonderful weekend :)
HI Ciara - That makes sense. Thank you for the guidence. Have a great weekend!
Hi Marko, A Wave2 draws 500mA of operating current when in use and a VISTA-21iP's siren output (terminal 3 positive, terminal 4 negative) is capable of handling sirens up to 2A. Therefore you should simply wire each Wave2 directly to the panel and not use the AD12612 auxiliary power supply at all. If you ever needed to add sirens that would put you over the system's 2A available siren output, you'd need more than just an auxiliary power supply and transformer. You'd also need a relay, like the Honeywell 4204, so that you could program the system to activate the relay that the siren is wired to when in alarm mode and turn the relay off when alarm mode stops. Then you'd wire the siren to the auxiliary power supply and the relay so that the siren has both the power it needs and the control from something to tell it when to go off and on.
Hello - I have a vista 21ip that I would like to add a AD12612 to support a 4th siren. I have the Honeywell transformer and battery and AD12612. My question is whats the conection from the main board to the AD12612 so that when it triggers the alarm will sound. Hope this make sense. I am using HOneywell Wave 2 sirens.
Thanks for the quick response. I was thinking that since the 4229 negative terminal is connected to the Vista 20P negative terminal and the AD12612 negative terminal, then that accomplishes the same thing as a common jumper between the Vista 20P and the AD12612, allowing me to hang keypads, etc. off the 4229 without the jumper. Right?
1. You must run a common jumper wire from the power supply's negative output terminal (DC - on the AD12612) to the panel's negative output terminal (4 on the 20P) for proper functionality. 2. You should be fine with having the sensors and keypad wired into the 4229 since that device is getting power from the AD12612, which in turn powers what is wired to it.
My Vista20P has some zones served from a remote 4229 expansion board and I'd like to add an auxiliary power supply (AD12612) to power the remote 4229 and the keypads/sensors connected to it. I have two wiring questions: 1) Is a common wire (-) required between the Vista20P and AD12612 to clamp down the reference voltage to 0Vdc, or is that not necessary because the common wire is connected to the 4229, which is in turn connected to the Vista20P? 2) Can the keypads be wired (+/-) from either the 4229 or the AD12612, or does the power now need to come from the AD12612 directly? Thank you!
Yes, the AD12612 power supply supports up to 1.2A and each 6280 only draws up to 270mA each. I would recommend getting a Tuxedo Touch WIFI (https://www.alarmgrid.com/products/honeywell-tuxedo-touch-wifi) instead of a 2nd 6280 though as it's a newer and better touchscreen keypad that also has a built-in Z-Wave controller. Finally, is your 21iP monitored now? We offer no-contract monitoring plans at https://www.alarmgrid.com/monitoring and as long as you aren't under contract with another company now, it's very easy to switch to us.
Hi, I currently have this power supply for my vista 21ip, I have one 6280 touch keypad. Do you think this power supply would be adequate if I hooked up a 2nd 6280 touch to it? Thanks for your help!
If you are using the AD12612 as the power supply for your siren, you'd want to connect the siren wires to the DC output. The flying leads (black and red) are meant for the battery terminals so the aux power supply stays on if you lose AC power.
Should I connect the wired siren to the DC output or the battery output? Thanks.
Thank you Sterling. Looks like I need to find a different charger. Maybe an Elk P624. Will start researching. Take care.
Honeywell's internal tech site says to "Use a standard 4AH, sealed lead-acid type." but doesn't state why they say to only use a 4AH battery so we would suggest going with Honeywell's recommendation to be safe.
Will the AD12612 handle the load of a 12V 7ah battery? Would I need to add a current limiting resistor? Values: ohm=?, Watts=? Note, Aux load: Std-by = 225ma, Active 612ma. Residential. Self install. Thank you.
Thanks for your help!
The operating voltage is rated at 9VAC 15VA or 12VDC 100mA so both types of input power would work but we do recommend the AD12612.
You could use the STI EM080735 (https://www.alarmgrid.com/products/sti-em080735 ) which isn't an "in-wall" enclosure but mounts to the wall and could house the AD12612 and a backup battery.
I'm confused. The 5800RL manual says it takes as input 9VDC, but the same manual recommends this power supply that delivers 12VDC. Which one ist it?
What in wall metal enclosure to you recommend using?
Thanks for the quick reply. Greatly appreciated!!!
No, you have to use the 1321 or 1361 transformer to power the panel and the AD12612 requires it's own separate 1361 transformer.
Is it possible for the AD12612 to power the actual vista panel in addition to other aux items? I am trying to only use 1 transformer instead of 1 for the panel and 1 for the APS. Thank you
