Exactly how to set time on DSC alarm systems

Figuring out how to set time on dsc alarm keypads is one of those annoying tasks that usually only comes up after a power outage or when the clocks roll forward or backward. You're sitting there, enjoying the quiet, and suddenly your keypad starts chirping at you because it realized its internal clock is off. Most people don't keep the manual handy, and let's be honest, those manuals are often written in a way that makes sense only to engineers.

The good news is that you don't need to call a technician or pay a service fee just to fix the clock. Whether you have an older PowerSeries model or a slightly newer one, the process is pretty much the same across the board. It's a quick sequence of button presses that takes about thirty seconds once you know the secret handshake.

Why your DSC alarm cares about the time

You might wonder why it even matters if your alarm system knows what time it is. It's not like it's your primary alarm clock for waking up in the morning. However, the system relies on an accurate internal clock for its event buffer. Every time you arm the system, disarm it, or a sensor gets tripped, the panel logs that event with a timestamp. If someone enters your house and the alarm goes off, you want the log to show the actual time it happened, not some random time from three years ago.

Also, many people use scheduled arming. If you have your system set to automatically arm itself at 11:00 PM every night, and the clock is off by six hours, you're going to have a very loud surprise when you try to let the dog out at 5:00 PM. Plus, that pesky trouble light (usually a yellow triangle or a light labeled 'System') will stay lit until the time is corrected.

The basic command sequence

To get started, you're going to need your Master Code. This is the four-digit or six-digit code you use to arm and disarm the system. Most residential systems use a four-digit code. If you never changed it from the factory default, it might be 1234, but hopefully, you've picked something more secure.

Here is the straightforward sequence for how to set time on dsc alarm systems:

  1. Press the asterisk key (*) and then the number 6.
  2. Enter your four-digit Master Code. If you enter it correctly, the keypad should beep quickly.
  3. Press 1 to select the Time and Date setting.
  4. Now, enter the time in 24-hour format (Military Time). This is where most people get tripped up.
  5. Immediately after the time, enter the date in MMDDYY format.
  6. Press the pound key (#) to exit and save.

Dealing with military time (24-hour format)

The 24-hour format is the biggest hurdle for most folks. The DSC system doesn't have an AM/PM button, so it relies on the 24-hour clock to know the difference between noon and midnight.

If it's currently 9:30 AM, you'll enter 0930. But if it's 9:30 PM, you have to add 12 to the hour, making it 2130.

Quick cheat sheet for the afternoon: * 1:00 PM = 1300 * 3:00 PM = 1500 * 5:00 PM = 1700 * 8:00 PM = 2000 * 11:00 PM = 2300

If you mess up the math, the keypad will likely give you a long, low "error" beep. If that happens, just hit the # key to clear everything and start the process over from the beginning.

Setting the date correctly

After you punch in the four digits for the time, the keypad is waiting for six digits for the date. It follows the Month-Day-Year format.

So, if today is October 15, 2023, you would type 10 15 23.

Don't try to put any spaces or special characters in there; just type the numbers one after the other. The system is designed to "know" when you've finished the sequence. Once you've entered the last digit of the year, the keypad should give you a happy-sounding series of beeps to let you know it accepted the info. If it doesn't, just hit # and try again.

What if you have an LED keypad?

Most of the instructions above assume you have an LCD keypad (the kind with a little screen that shows words or at least big numbers). But a lot of older DSC systems use LED keypads. These are the ones that just have a bunch of numbered lights that glow red or green.

On an LED keypad, you won't see a "Time" prompt. You just have to trust the process. When you press * 6 [Master Code] 1, the "Program" or "System" light will usually start flashing. This is your cue to enter the 10 digits (4 for time, 6 for date). You won't see the numbers you're typing, which can be a bit nerve-wracking, but just take it slow and steady.

If you make a mistake on an LED keypad, you'll usually hear one long beep. That's the system's way of saying "I have no idea what you just typed." Hit # and start over.

Troubleshooting common issues

Sometimes, you follow the steps perfectly and it still won't work. Here are a few reasons why that might happen:

The Master Code isn't working

If you enter * 6 and then your code, and you get a long error beep immediately, the code you're using isn't the Master Code. It might be a regular user code. User codes can arm and disarm the system, but they usually can't change the system settings or the clock. You'll need to find the actual Master Code. If you've lost it, you might need to contact your alarm company to reset it for you.

The Trouble Light is still on

If you set the time and that yellow triangle is still staring at you, the time might not have been the only issue. Press * 2 on your keypad to see what else is wrong. If the number 8 lights up (or the screen says "Loss of Clock"), it means the time still isn't set. If a different number lights up, you have another issue, like a low battery (usually number 1) or a phone line trouble (usually number 4).

The system is "Busy"

If you're trying to set the time while a door is open or a motion sensor is being triggered, some keypads might act a little finicky. It's always best to make sure the "Ready" light (usually green) is on before you start the programming sequence.

Why does the time keep resetting?

If you find yourself searching for how to set time on dsc alarm every single morning, you have a bigger problem. Usually, this means your backup battery is dead.

Inside the large metal box (usually hidden in a closet or basement) is a lead-acid battery. This battery is supposed to keep the system running and the clock ticking if the power goes out for a few minutes. If that battery is old and can't hold a charge anymore, even a tiny flicker in your power grid will cause the alarm panel to reboot and lose its memory of the current time.

If you see a "Low Battery" warning along with the "Loss of Clock" warning, replace that battery first, then set the time. Otherwise, you'll be doing this every time the wind blows.

A quick tip for Daylight Savings

Since we have to do this twice a year in most places, it's a good idea to write the sequence down on a small piece of paper and tape it to the inside of your alarm panel door or keep it in a kitchen drawer.

* 6 + [Code] + 1 + HHMM + MMDDYY

It's a simple string of numbers, but it's remarkably easy to forget when you're tired and just want the keypad to stop blinking at you.

Wrapping it up

Learning how to set time on dsc alarm isn't exactly the most exciting skill to have, but it's a handy one that saves you from the annoyance of the "trouble" beep. Just remember the golden rule: 24-hour time format. As long as you get the military time right and use your Master Code, you'll have that yellow light turned off in no time.

If you've tried everything and the keypad still won't cooperate, don't force it. Sometimes the keypads themselves can get "stuck" in a programming loop, or there might be a hardware fault. But 99% of the time, the * 6 method is all you need to get things back to normal. Now you can get back to your day without that nagging yellow light reminding you that your house thinks it's midnight in 1995.
