Our Customers Say

Rated 5 Stars!“We recently eliminated our home phone line and had an upgrade done on our alarm system. I want to comment on how well Doug Brown handled the job & made it an easy transition for us. Our installer Dan was one of the most talented people I have had work in our home in recent years. He was careful, the equipment was mounted neatly & the job was left as clean as he found it. He also did a great job of explaining how to use the new features. Thanks, Steve.”

Service FAQs

I Hear BEEPING!

Many customers assume that beeping they hear is their alarm system. While your alarm system will beep to tell you when something is wrong, other items will beep as well and often it is not the alarm system at all. Items like non-monitored smoke detectors installed by electricians, backup batteries for computers/media equipment and even ovens all beep to communicate with you.

If you hear beeping and can’t isolate where the sound is coming from, walk over to your keypad. Your keypad will also indicate visually that something is wrong and the first step is to check the Status of the alarm system. To find the Status for your alarm system, consult your user manual or find your keypad below for instructions for your specific system.

Still aren’t sure? Give us a call and our technical staff is here to help 24/7.

Why Won’t My Security System Arm?

The most likely reason for trouble arming your system is open zones. Your system is designed to only arm when all protected doors and windows are closed. In your user manual, locate the Status button; every system has a button which provides this information.

If you are unable to identify the open zone, double-check for any protected doors or windows left open. If you are still experiencing a problem, call us at 410-546-2210.

How Do I Change my Alarm System Battery?

Just like batteries in vehicles, watches, and flashlights, alarm system batteries eventually need to be replaced. There is at least one main battery on your alarm system which powers it when AC (electrical) power is out. Unless your door and window transmitters are hard-wired, you have batteries in those devices as well. Most security systems have a main external system battery, but some systems have an all-in-one design where the battery is contained in the keypad itself. Typical system battery life is 3-5 years, depending on many factors including how often the power goes out.

Monitored alarm systems automatically test the back-up battery and signal the central station and you if the battery is nearing end-of-life. When power is down, the system conserves power by dimming the keypad. As the power drains expect a low battery notification – most likely a beeping sound. These alerts are expected and are for your protection.

Depending on the type of alarm system installed in your home will determine the type of system battery it takes. Find your keypad image below for specific system battery replacement details. Window/Door Transmitter batteries are often the same “coin” battery used in your vehicle keyfob and can be purchased anywhere. All system or transmitter battery replacements can be purchased from our office (for quickest service, call us ahead and we will have it waiting for you!) at 2204 W. Zion Road in Salisbury, MD. If you aren’t close to our office, most system batteries can be purchased at PASCO or Interstate Batteries. Of course we can send out a technician to change it for you as well: 410-546-2210, option 2.

How Does my Alarm System React During a Power Outage?

All modern alarm systems have battery powered backup keeping the system functioning uninterrupted when AC power is down. Beyond that, how long that battery will last during a power failure varies. Alarm systems can function without AC power for hours, even days, depending on many factors. If you have a generator, be sure your alarm system is connected to that power source.

What Happens to my Security System when the Power is back on?

After power is restored the system should recharge the battery within 48-72 hours. If after several days with power the system still displays low battery, the battery likely needs replacement. The DIY solution: bring your battery into our office or to a battery warehouse. (Before replacing the battery yourself please consult your user manual, or feel free to call our office with questions.) Of course, we can come out and change the battery for you.

If you’re unsure how long it’s been since your battery was changed, don’t wait for a power failure to test your battery. A proactive approach to your battery backup keeps your loved ones and valuables protected during power failures.

Traditional landline phone lines are becoming less reliable for alarm communicationDoes making changes to my phone system impact my alarm system?

Perhaps. If you are considering or have already cancelled your landline phone service to move over to VOIP (such as Vonage or Magic Jack) or switched to Comcast there may be an impact to your security system. Any work done on your phone lines or phone system may also impact your communication to our Central Station. Call our team to see how your account is communicating today and we’ll let you know if a hardware upgrade is needed for your system to work without the phone line using your Customer Loyalty Credits.
