My alarm system shows BAT flashes, is it necessary to replace just the back up battery or the transformer as well ?

You only have to only replace the backup battery. The transformer is for the hard wire connection.

In two different houses each time I just replaced the battery and all worked well. Remember to contact your security company to make sure they re-initialize the system from their end.

No. I've checked vendor website. Nothing about mute alarms. Also checked tech forums re: Tripp Lite battery backup, all had same complaints with no solution. If you come across the answer, please post link to it somewhere. For now, will keep Googling for it.

Let me start by commenting on the date on the device, since it has come up in other posts. I ordered my smoke alarms in May and the device was stamped end of March which seemed quite reasonable. Yep, replacement time is 10 years and if I do it exactly on the 10 year mark I'll be amazed with myself. As per your question Edwin I hooked up my alarms to the house power and they did the low battery beep until I pulled the plastic tab out of the side of the detector which made the battery connect inside the unit itself. I used the battery that came with the unit and didn't need to ever open the battery compartment. When I do replace the battery if it continues to beep I would check the battery connection and also make sure that my batteries were not dead. I expect to replace all the smoke alarm batteries the first of the year, which is what I used to do, and didn't bother this year because I knew I had to replace the detectors. Best of luck with your smoke detector.

This is a hard-wired alarm w/ battery backup. For a dual alarm powered only by battery, look for First Alert SA320CN Double Sensor Battery-Powered Smoke and Fire Alarm

J. Hur,This will not be a problem. I have 3 different models connected to my hard wired/ plus battery system. A total of 6. Some with different sensitivity than others. Since they are all made by First Alert / BRK. I haven't had any problem with them for over 21 years now. Plus they all come with a wiring harmess pigtail, should you damage your old one . I have noticed some of the new replacment detectors have replaced the 9-volt battery with two AA . To be honest, I think it's better . I hope this helps you.Ronnie

Open the batt compartment and see the part no. If it maches then you are good to go. If not look for replacement with the part no of your batt. I'm sure u will find it here.

My battery was detected by the system. However, the system alternated between charging and line AC power. The icon kept flashing on and off, making the system unstable and unusable. I blamed my PC for the problem because the old battery had begun exhibiting the same behavior. The PC works fine on AC line power, a bummer of a situation. I did not return the battery because I felt that my laptop was likely at fault.

No transformer is necessary as the unit uses two 1.5 volt batteries. The bottom of the unit pops off and the batteries can then be replaced.

Yes, the alarm is AC power. The battery is only meant for the possibility of a power outage. The battery only last for the 36 hours after the alarm is triggered, but I don't know how long the battery last if it is not sounding. Since there is only pull on the battery after the trigger, I am guessing that the length of the battery life is as long the battery itself. I have one more thing to tell you. This thing is pretty loud when it goes off if you haven't heard it yet, so you'd definately be able to hear it...probably in your neighbors basement!If you have anymore questions, don't hesitate.

If the unit chirps at seemingly random times or at random intervals after replacing the battery, check for the following conditions: 1) The battery may be loose, or improperly installed. The smoke alarm cover may be dirty. 3) Reset the alarm. 4) An electrical condition may be causing the power to the unit to be interrupted. If the AC power to the unit is interrupted, the unit will chirp when the power is restored. This could be caused by power surges. 5) Replace the alarm.

Nope, backup siren is incase they cut the wires to your primary siren, backup battery is in case they cut the battery power to disable the alarm. If the siren is hard to reach, you will be fine. What many do is pop the hood and cut the power to the battery. I myself just have the backup battery

According to the manual, a low battery indicator will sound off with a continuous beep followed by a single beep. That is your warning to replace batteries. If the batteries completely drain, the lock is included with an emergency backup battery pack for you to hide in a special place and use as your power supply if you were unable to replace batteries in time. Does that answer your question? I don't believe there is an override to the code itself, if you overwrite default code and then forget your own code.

No, Just change the battery. Do a self test and you should be good. My transformer burnt out due to hurricane Sandy

FYI: I bought a interstate battery and connect the water indicator probe to the negative terminal so the alarm does not sound. works great. the watchdog batteries are JUNK. don't waster your $ on their battery but the system is great otherwise

The backup battery is tied separately to the security system in case your battery terminals are disconnected the alarm system with still sound.

If you're replacing one, it's something you'll probably just need a screwdriver for. Just don't touch any bare wires together that aren't already touching. It won't hurt, but could set off your alarm. I'm not sure if it works with all systems, but it worked well with ours.

Mine did not need those batteries. The older version I had needed a 9volt battery as the backup but the new version came with a large "watch" type battery. I did not even look in the manual about anything else so don't think it needs them???
