Replacing the battery in your ADT alarm system is not a complicated one, and you can attempt it on your own. This way, you guarantee that your system will remain functional and send alarms when necessary after having the battery changed. Here are the recommended procedures that you need to follow if you want to learn how to replace the battery of an ADT alarm system:
Before You Begin ADT alarm systems typically utilize 12-volt 7Ah or 12-volt 4Ah sealed lead acid batteries most often in their systems. You will be required to buy a new one that is of the same kind as the one in use in the market. It is common to advise that alarm batteries be changed every 3 to 5 years, and this is the advice that ADT usually gives to its clients as well.
Ground yourself with the information given on the manual of the system or the sticker on the battery to identify the type of battery to use. In general, compatible alarm batteries can be purchased at stores that deal in electronics and hardware products.
After getting the right battery for the keypad, ensure that you have the passcode to disable your system. You must turn it off before replacing the battery but you should know how to do it.
Locate the Battery The ADT control panels and their backup batteries are typically mounted near an entry door where the wiring passes in. They are usually placed in the garage, basement, closet, or laundry room of the house.
In case you are not sure about where the batteries are, look at the vicinity that is near areas where the keypad is installed. The battery compartment is likely to have a cover that will require to be unscrewed to reveal the battery.
Disable the System To turn the system off, enter the passcode at the keypad of the alarm. This helps to avoid false alarms when opening circuits in the electric circuit.
If you enter the code again and again it may cause a false alarm which results in the dispatch of a fire tender. When choosing your code, take time to press the right number to avoid any mix-ups.
Open Battery Compartment The battery compartment will have a push tab you slide over or screws that would need to be undone to remove the battery cover or door. Pull the tab back to open, or twist the cap off fully to reveal the battery.
Remove Old Battery First, grasp both terminal ends of the battery and pull upwards in a vertical way to remove it from the compartment. Take particular notice of the polarity and location of the terminals, as these will need to be replicated once you insert a new battery.
Inspect Compartment Locate the battery compartment and look at the terminals or the contacts for any signs of corrosion or accumulated dirt. Wash off any oxidation or residue present on the metal substrate using a wire brush or sandpaper. This helps to maximize contact as the firm would now be directly in touch with its end consumers.
Install New Battery To connect, first connect the red battery lead to the positive terminal on the new battery. This wire lead denies reversal of polarity any time you attach the battery.
Now gently place the battery back into its housing to ensure that the terminals are aligned to the leads that were cut. As mentioned above, reconnect the black lead to the negative terminal.
Restore Power and Test Place the compartment cover into its rightful position and align the tabs into their rightful position or close the door by screwing it. The system will first identify the battery before proceeding to measure the voltage.
Press the star button again on the keypad to arm the panel, and re-enter your passcode. Next, open an exterior door to activate the alarm and see how the system responds. Make sure that the system triggers an alert and plays the siren properly.
If the alarm does not respond properly then remove the battery and ensure polarity was as expected and the wires were well connected.
Battery Disposal Alarms systems have batteries that consist of lead and destructive sulfuric acid; thus, they are required to be disposed of in a particular manner. Find a battery recycling center or a facility that collects hazardous waste to take your old alarm battery for proper disposal.
Replacing a bad alarm battery is a small chore that any person can do easily. Failure to use the right polarity and testing the system once you are done puts your ADT security system in good condition. It is recommended to check the battery every couple of years for any corrosion or signs of swelling to gain the maximum life out of the new battery. These few extra minutes can prevent false alarms and avoidable equipment downtime due to dead batteries.
