    • The magnetic entry alarm is easily mounted to windows or doors with included double sides adhesive tape, no tools required

    Door Security System

    • Made of high quality material, the door security system is durable and reliable for long time use

    Home Security Magnetic Contact Installation:

    • One way to secure a home is to install magnetic contacts on doors and windows. These devices consist of a pair of magnets wired into a home-security system. When the magnets are separated (either from a door opening, or a window sash being lifted), the sensor alerts the main security panel of the fault. Magnetic contacts are easy to install and can help improve your family's peace of mind

    Door Contacts:

    • Door contacts are typically mounted along the top edge of the door, on the safe side of the door, opposite of the hinges. This placement allows for the magnetic sensor to trip after the door is open just a few inches. Mounting the sensor by the hinges might not provide enough of a gap to trip the alarm, even if the door is opened enough to allow an intruder to gain entry

    Window Contacts:

    • Magnetic contacts on windows work best on windows that have moving sashes. Contacts are often mounted along the center of the window, with half the magnet on one sash and half on the other so that the alarm will trigger if either pane moves. For large picture windows, install a glass-breakage sensor in addition to magnetic sensors. Do not expose sensor wiring in a way that may encourage a determined intruder to cut wires or to break a small pane of glass to simply unscrew the sensors from their mounts

    Wiring and Mounting:

    • Even the best-quality equipment is useless if the magnetic sensors are mounted insecurely, or if the wiring is exposed. Always sink security sensors firmly into studs or masonry with heavy-duty screws. If possible, use screws that require bits other than flat- or Phillips-type drivers. Run wiring inside of walls where possible, or protect it with metal conduits


    • If the magnetic contact uses electromagnet technology, plan for possible power failures. The security system should have its own residual battery backup to provide protection even during utility outages. Avoid using wall plugs for do-it-yourself electromagnetic sensors, and avoid wiring different parts of the security system into different household circuits, as a breaker trip in one circuit may "confuse" the alarm system and cause false alarms

    How to Buy a Home Alarm System:

    Magnetic Sensor Alarm

    Each year more than 2 million American homes are burglarized, according to the National Burglar and Fire Alarm Association ( Most of them have no alarm system. Electronic security devices provide affordable peace of mind, and recognizes and reacts instantly to unauthorized entry

    • Survey your home and determine how many windows and doors you want integrated into the system
    • Contact your insurance agent, a security system adviser, the NBFAA or your police department's crime prevention department for names of security system companies. Ask each company for an inspection, a recommendation and a quote in writing
    • Decide whether you want to contract with a 24-hour central monitoring station for a monthly fee. If your system detects a break-in, it alerts security professionals to dispatch local police. Less expensive dialer accessories can link sensors to your phone lines and call preselected numbers if security is breached
    • Consider your family's lifestyle. Do people or pets sometimes roam the house at night? Select appropriate sensors and locations
    • Choose a system with a control panel that can monitor all the zones in your home. Each window or door integrated into the system is considered a zone. A basic system (about $400 without monitoring) can control eight zones, but many can be expanded to watch up to 32
    • Determine locations for the control panel and keypads. The control panel commands the system and the keypads allow you to program the system and turn it or its components on and off. A typical setup puts one keypad near the front door and another keypad--and perhaps a panic button--close to the bedrooms
    • Look for systems that connect to lighting controls, smoke and carbon monoxide sensors, and flood detectors. Also make sure system switches won't freeze in cold climates. (See How to Buy a Home Automation System.)
    • Choose a user-friendly code that everyone in the family can remember in an emergency. Try the keypad to assure that it's easy to use
    • Realize that it's difficult to retrofit a hardwired security system. With a wired system, you'll have to drill holes in walls so wires can be routed. If you want to avoid this expense and inconvenience, choose a wireless system

    • 1 x Pairs of Door Magnetic Sensor

Alarms are used in my apartment and are really loud. I have it on my window and front door. It has a chime (sounds just like a doorbell ring) and a regular beeping alarm.

Great for sneaky kids
00:00:00 05-12-2011
I can't hear my child go downstairs until now. She is scared of the door alarm but the chime works perfect for her. We needed something to make sure she was not sneaking downstairs while we were sleeping. I wish they had different chimes to tell which door it was that was opened. Thank you for help keeping my kids safe.

Perfect for our needs
00:00:00 04-29-2011
I didn't buy these for home safety but for my childs safety. I have a special needs child who does not have a sense of danger or fear and also requires very little sleep. I needed something to alert me to doors opening because he cannot be outside alone. I love the chime/alarm option. We keep it set on chime during the day and have made it a habit to announce who opened the door so every one knows it isn't him. Then at night we switch to alarm so we will be woken up if he slips out. <br/> <br/>These have been installed for 1 1/2yrs and the adhesive has held them in place with no slipping and the batteries have not needed to be changed.

the best
00:00:00 03-30-2011
Nice security system which would probably the best at this price range. Window Alarm is loud enough but the best alarm is the door. Must buy if you dont want to pay for the pricey calling features or monthly services.

Not bad!
00:00:00 03-24-2011
For the price, this is a handy little gizmo that goes up reasonably fast on standard windows and provides a nice layer of additional security. I just worry about getting replacement batteries at a reasonable price, as opposed to just tossing the device and buying a new one when that time comes. Still, I bought a handful and they provided some welcome peace of mind following a burglary of my home.
