I just did mine after calling ADT for a blue shield type, they told me I could change it but said nothing about this procedure,,,,,,wanted to send a tech,,,,I did it and saved 25 dollars on a service call,,,,thanks for the info it works.
Hey no problem! Glad you got it going. We like helping people save money and take back some of their own power to do it themselves. Thanks for watching the video. Have a great day!
What kind of battery was to replace to your adt siren?
Yeah I just called and was told they recommend a tech doing this. $25 for the first 30 minutes and $100 afterwards! I’m tempted to try it myself
@@jakesandlin2727 did u just un plug and replaced and then followed the video instructions
@@deehood3178 I didn't do mine. They sent out a tech and didn't charge me.
Excellent video, very informative. Just changed the battery for the alarm system, and it worked like a charm. Thank you.
Thanks! This process has been one that has confused a lot of DIY installers and we're glad we could provide some guidance on it. Glad you found it useful :)
Great video. Made it easy to understand how to reset siren when changing battery
Great video didn't know about having to pacify the battery thx alot 👍
Thank you
What size battery is needed for the 4911B blue strobe? Can it be purchased at a local hardware store?
Just did mine and working good. But after that the siren shut down and the control panel didn't enroll the siren. Did i do something wrong?
Thank you so much! I followed your instructions and everything works fine. Woohoo!
Did all the steps, lights are flashing but not a buzzer after the last step. Right now, the lights are flashing, inside the panel still no show temperature.
Hi ryan, how do you know when the battery is actually bad?
When plugging in to the 3 pins, does it matter which way it goes in? Release tab up or down?
The connector should only fit one way, and that would be release tab down if the siren is oriented like it is in the video.
Can you replace the battery with a power adaptor 3.6Volts output same as the battery? The battery does not last that long especially if you have a couple of false alarms
It was not designed for that style of setup, so no I do not believe that would work.
I changed the old battery with a new one. I followed your steps de-pacify, sirens flashed waited for the beeping 30 mins later it started to beep pressed the button. I still have the triangle showing low battery inside the house. Did this step twice. Key pad inside the house said low battery siren. What am I doing wrong?
I have the same issue. Did you find any solution?
@@stilus007 same here
I followed the directions but the strobe is still blinking after a several minutes, and it hasn't beeped. What am I doing wrong?
These outdoor wireless sirens are defective junk and have an extremely high rate of failure. My advice, toss the piece of crap into the garbage and install a powered siren instead to save yourself a ton of cash and headache in the long run.
I did all these steps but nothing happenes when i replace the battery.
If you failed to do this step (my local installation guy didn't do this) can that damage the siren permanently or would it work after doing the process correctly?
It won't damage the siren, but the siren will not work unless you do this step
already carry out this work the siren works but the strobe does not work
If the siren works and sounds when there's an alarm, but the strobe doesn't then I would think that the LEDs may be burnt out in the strobe light. That would be my first guess.
Thank you!!
Would I need to de-pacify the old battery before removing it.??
It just sucks that if you have more than 1 of them. You will have to take it completely down to see the esn number on the underside of it. I write mine on the inside.
As I can restart the ESN of a siren.
Of damaged alarm, for use in another
*8 installer code
Section 804 sub section 301-304
Aka
Siren 301 is siren 1-304 siren 4
You can enter ESN maually
* key makes numbers on key pad alpha numeric
or in some cases if not enrolled in another system, section 898 then tamper siren should work
These wireless outdoor sirens are overpriced junk. Most of the time the battery depassivation process fails meaning you waste 30 minutes with each attempt. I've seen BRAND NEW sirens that are tested working fail multiple times when changing out a "low battery."
I had a BRAND NEW siren fail within 2 months, the wireless communication part just stopped working.
If you're smart you will never buy this DSC product because it has a high rate of failure and DSC should be sued for selling this defective garbage 🤬
....yellow triangle still present....how to reset after replacing baTTERY?
It will reset automatically IF the active trouble is resolved. If it hasn't you still have an active problem.
What are the consequences of not doing this?
The consequences would be that the siren wouldn't operate correctly or at all. This precise process needs done
I hate these things
These sirens are garbage, you'll agree when it's 0 degrees out and your waiting 40 m for dam thing to beep 🤦♂️
The older WT wireless sirens could definitely be troublesome, but they upped their game for the newer DSC NEOs wireless sirens. The batteries don't require depassivation and they've performed flawlessly for us for years since they released.
