Permanently disable security system

Question

We moved house about a year ago. The previous owner had an alarm system, which we assumed was inactive, but whenever we lose/regain power, the panels beep intermittently.

We've somehow armed the system though, and now the alarm goes off whenever we enter the house. We don't have a code, so we have to turn the mains off, which stops the alarm but leaves it armed.

Is there a way to permanently disable the system? Here are some pics of the panels and what I believe is the control panel.

Thanks in advance.

Answer 1

Per your pictures you have a DSC 1832 system and the manual can be found here. What you might try is doing a factory reset

1. Power down the system completely.
2. Connect a short (wire) between Zone 1 and PGM1 on the control panel (remove all other wires form these terminals).
3. Power up the control panel (AC power only) for 10 full seconds.
4. Power down the control panel, remove short between Zone 1 and PGM1.
5. Power up the control panel.

Once you have the system reset, the manual walks you through the process to set it up for yourself.

Answer 2

Disconnect the battery and the power supply (if you can find where it's plugged in, somewhere near the brown box, unplug it.) Unfortunately your picture of the label is not quite clear enough to read.

But the first two wires on the left of the power strip say 16 VAC, so that's the power supply that's plugged into the wall somewhere, and the plug to the left of them looks to be the battery.

Usually looks like this, more or less:

If you can't find and unplug the 16 VAC transformer, cap off those wires with a wirenut and/or electrical tape. Actually likely more reliable to remove only one of them and cap it (which still shuts the system off, but reduces the odds of the two coming into contact with both loose.) But better to find and unplug it (if not found, try taking the box off the wall, it may be behind)

In most cases you can look up the alarm model number and find out how to reset it (Relevant, no affiliation) so that you can control and use it, rather than disabling it permanently.

You need to disconnect both AC power and battery power.

The battery is easy - remove the red and black wires from the terminals on top of the battery.

The AC is a bit trickier. AC power is coming on the left-most black and red wires on the left terminal block. They should be connected to a power adapter or transformer "somewhere". That could be a plug-in block plugged into a regular 120V AC receptacle. Or it could be a transformer mounted on a box somewhere like a doorbell transformer. Turn off the breaker for this circuit (if you do that after you disconnect the battery then the alarm will be totally off) and then trace the wires and disconnect them. Do not disconnect the wires from the terminal block without also disconnecting them from the AC source. Otherwise they could be dangerous for someone who doesn't know they're live (though not a huge danger because they are low voltage) and also some future person may find the transformer or power pack and not know they can remove it.

Can I just remove contact points screwed into my threshold/under the door? No more monitoring company but it’s very loud alarm when we open that door after we lose and then regain power. I know the code to stop it— but if I’m away and I have handyman over or one of grandkids stops in, it’s crazy. Everyone seems uncomfortable with disarming it with the code. I even have number taped to top of keypad box!!!
