Adding Envisalink EVL4 - Auxillary Power Max'ed out?

Threaded View
I plan on purchasing an EVL4 shortly but have a question regarding Auxiliar
y Power Maximums. I have a Vista 20P control panel with the below auxiliary
 devices which have a total current draw of 535ma (as stated in the 20P ins
tallation manual). Adding a EVL4 at 75ma would bring the total Auxiliary Po
wer draw to 610ma. The Vista 20P documentation states that the Auxiliary Te
rminal power available is 600ma . This is a residential (non-UL rated) inst
allation.

I think I can make the assumption that the Alpha Keypads would only reach 1
00ma maximum if the keypad sonalert and the panel backlighting LED lights a
re activated at the same time. If that is the case I hoping that the extra  
10ma overage would only be reached in a worst case scenario.

I'm trying to save having to deal with a second auxiliary power supply and  
its associated power transformer but want to insure that I'll still be able
 to access the panel remotely in that worst case scenario.

Does anyone have a comment on what I should do here? Thanks for your help i
n advance.

Current Devices
(2) 6160 Alpha Keypads (100ma each - total 200ma)
(1) 5881 RF Receiver (35ma)
(1) 4286 Phone Module (300ma)

Best hope is to turn "off" all buzzers and led's on keypad's and sensors  
(when you can)..

Do an actual current check on the power out (paper work is fine for a  
starting point, but each device can be different than the norm)

a second power supply is not that expensive and can save a lot of  
problems down the road... (just remember to follow the instructions)

Your car can do over 100 miles an hour.  

If you could do it lawfully, would you actually drive it that fast everywhe
re you went? Think about it. And why wouldn't you? Maybe because it wouldn'
t last as long ?? huh? Maybe? Ya think?

Put in a aux power supply ???. Jeeeeeeze!

Thanks for the advice....my issue was to try and squeak by with just the on
e power supply.  

As I'm sure you must know that you can't use the same transformer to power  
both the main alarm panel and the aux power supply.  Therefore adding an au
x power supply will require me to do additional electrical work to add anot
her AC outlet for the second oversized 1361 transformer.  Also it requires  
purchasing an additional battery to provide the necessary backup power in t
he event of a rare power outage because as you must know, Honeywell states  
you can't connect both to a single battery. All of this would likely requir
e an additional secure box so that all this additional hardware wasn't read
ily accessible.  

So as you can see, this simple task has just turned into something a lot mo
re complex for the sake of a measly 10ma of additional current required by  
the hardware.

But if for nothing else I learned something about driving my car over a 100
.  I never thought it wouldn't last as long.  My first thought is I'd have  
to wear "Depends" if I did go that fast.

Have a great day and please keep on posting for the benefit of all.

not true about the single transformer..



may not sound right but we been doing it for years..


case...

just remember to follow the instructions about connecting the extra  
power supply (-) together..

** just remember the LED's on the sensors and back light on keypads is  
what draws all the power..

You can use the 4 Amp hour battery and the larger 40VA plug-in transformer  
as Rocky suggest as a common source or just use a power strip or one of tho
se multi-plug expanders to gain another outlet to plug the second transform
er into. You can use tie wrap/cable ties / zip ties to strap the transforme
r so it doesn't fall out of the outlet plug.  

As Rocky said ?? Don't forget to run a common wire between  
the negative terminal of the power supply and the negative terminal of the  
alarm control panel auxiliary power output.  

And OH Yeah!  Wearing Depends is for sissies !
