Method 1: Instructions on resetting the DSC alarm when it sounds continuously.

Step 1: How to enter the code to restart the DSC alarm

1. Open the protective cap and enter the master code twice.

• Open the small access door and pull down the keyboard cover to reveal the keypad.

• Enter your 4-digit master code, wait about 2 seconds, then enter it again a second time.

• If you make a mistake, press the # key to delete and start typing again from the beginning.

• The default code for many DSC templates is usually 1234 (if you haven't changed the code).

2. Effectiveness of the code entry step

• In some DSC models, entering the code twice will automatically reset the alarm and stop the chime.

• This step can also automatically clear warning lights such as Trouble, Armed, and Memory.

• If the system is still beeping or the warning light is still on, you need to continue with the next reset steps.

Step 2: How to use the Reset button to turn off the DSC alarm.

1. Press and hold the Reset button for about 2 seconds.

• Check the bottom right corner of the keyboard; most DSC systems have a Reset button in this location.

• Press and hold the button for at least 2 seconds to deactivate the alarm system.

• When the reset is successful, the status light usually changes from red to green, indicating that the system has returned to normal.

2. When should you use the Reset button?

• This action helps to quickly silence the noise and return the control panel to a stable state.

• If the system experiences a power outage and then power is restored, the Reset button also helps to clear the low battery warning.

3. In the case where there is no Reset button

• Many DSC models do not have this button, so you can skip the above step and proceed to the command-based reset step to continue processing.

Step 3: How to use the *72 command to stop the DSC alarm from ringing.

1. Enter the command *72 on the keypad.

• If the system continues to beep after you've tried the initial reset steps, enter *72 directly on the keypad.

• If the keypad has an Enter key, press it again to confirm the command.

2. The effect of the *72 command

• This command resets the smoke sensors, which are often the reason why the alarm continues to sound even after the system has been entered with the code.

• After the sensor is reset, the alarm will stop sounding and the control panel will return to a stable state.

3. When should you use the *72 command?

• Suitable for use when the alarm is triggered by smoke, steam, or a minor smoke sensor malfunction.

• This is a quick troubleshooting step before further inspection or calling a technician if the alarm continues to sound.

Method 2: Instructions on adjusting the DSC alarm time after a power outage.

Step 1: How to enable date and time adjustment on the DSC alarm

1. Press *6 to enter the settings.

• Open the keypad cover and enter the command *6 to access the system's custom menu.

• This is the first step when you need to readjust the time after the alarm has been lost or reset.

2. Enter your master code.

• After pressing *6, enter the master code (many DSC systems use the default code 1234 if you haven't changed it).

• If the code is correct, the system will allow you to continue the setup.

3. Press key 1 to access the Date/Time settings.

• Press key 1 to open the date and time settings.

• Here, you will re-enter the date and time in the format required by the system.

Step 2: How to correctly enter the date and time on the DSC alarm.

1. Enter the time in 24-hour format.

• Use the keyboard to enter the time first.

• The DSC system only accepts time in 24-hour format (military time).

• For example, 2:00 PM would be entered as 1400.

2. Enter the date in MM DD YY format.

• After entering the hour, continue entering the date in the following order: month – day – year.

• For example, September 20, 2022 would be entered as 09 20 22.

3. Why is it important to enter the correct format?

• Entering the data in the wrong order may cause the control panel to display an error or fail to save the settings.

• Setting the correct date and time helps the DSC system record events at the right time and avoids false warning lights.

Step 3: How to save the date and time after entering it on the DSC alarm.

1. Press the # key to save all changes.

• After you have entered the correct time (24-hour format) and date (MM DD YY format), press the # key on your keyboard.

• This is the final confirmation step for the system to accept the information you have just entered.

2. Results after saving

• When the # button is successfully pressed, the DSC system will record the new date and time and exit the setting mode.

• The control panel will display a stable status, with no more time-related error messages.

3. Why is this step important?

• If you forget to press #, the system will not save the information and may continue to display the warning light.

• Accurately recording the date and time helps the DSC alarm function correctly, recording events at the right time and avoiding unnecessary alerts.
