Body Alarm

The body alarm or personal alarm is a safety tool device that when activated, sets off an extremely loud siren sound. These are usually lightweight, portable alarms that should be worn within convenient reach. If someone attempts to harass or attack you, you don’t have to work to find the button, or rummage around in your purse looking for the alarm. Some can be worn on the waist or belt with a clip, or worn around the hand and held when you’ve got to walk through a bad neighborhood, a dark parking lot at night, or any place else you deem unsafe.

If you’ve ever heard the sound of a body alarm, you know that it is very loud and can almost hurt the ears. The hope with most types of the body alarm is that making such a loud sound will discourage people from attacking you since it is likely to draw attention to you and a would-be attacker. Anyone in the near vicinity will hear this alarm, though there’s no guarantee they will respond to it. The rate at which people ignore car alarms is fairly high. This means the body alarm might provide a little extra safety, but isn’t a substitute for good training in self defense and common sense decisions regarding your safety (like walking in pairs through a dark parking lot).

The body alarm should be kept out of reach of children, since long exposure to the sound can significantly damage hearing. On the other hand, an older child who can be trusted might want to carry one when walking unescorted to and from school. You may have to check with your individual school to find out if they are allowed on your child’s campus. Usually no one objects to one being kept in a backpack during school hours.
This type of alarm can come with other handy features. For instance many also have flashlights and most are powered by batteries. It’s a good idea to change these or check battery strength from time to time even if you haven’t used the alarm. Most body alarms are very slight and small, weighing merely ounces, so they’re very easy to carry. They’re also inexpensive, with the majority between $10-20 US Dollars (USD).
As you’re searching for a body alarm, you may notice a completely different type of personal alarm used for people who have difficulty staying awake while driving. This is worn like an earphone, and if your head begins to droop while driving, you hear a small alarm to keep you awake. Again, such an alarm is no substitute for making safe driving decisions, like not driving when you’re sleepy.

The Best Wireless Smoke Alarm

Choosing the best wireless smoke alarm is usually not difficult, as most function generally in the same way and do the same things. Most run on 9-volt battery power, but other power sources may lead to more convenience at a greater cost. Also, some wireless smoke detectors work through an ionization process whereas others work through a photoelectric system. Another feature to consider is connectivity of alarms throughout the home.

If you find you cook at a great deal, and have a smoke detector that is routinely set off because of steam and smoke from that activity, a photoelectric smoke detector may be the best choice. Ionization detectors tend to be much more sensitive to smaller particles in the atmosphere and therefore are more prone to false alarms, especially when cooking. If you find you do not want the expense of a photoelectric smoke detector, it is possible to mix and match in different parts of the house. Both are available in wireless models.

One feature that may help some who have a wireless smoke alarm is to make sure the system has a silence button. This will generally reset the alarm so that it does not offer an alert for a certain period of time. After that point, if conditions are detected that could possibly be smoke, the alarm will sound again. This is also convenient for smoke alarms near kitchens or even showers, where steam could affect the systems.

The power source of a wireless smoke alarm could also be an important consideration, especially if you do not want to change batteries in a wireless smoke alarm every six to 12 months. In the past, options have been limited, but more smoke detectors are appearing on the market with alternative power sources that use lithium or other types of batteries. These are marketed as lasting as many as five to 10 years.
Another current technology pushed in some wireless smoke alarms is inter-connectivity. With larger houses, or houses with multiple levels, a fire alarm in one portion of the home may not be heard in another portion. Some smoke alarms are connected wirelessly together so that if one sounds, all the others also sound. This safety feature ensures that all parts of the home are aware of a possible fire. The transmission unit is usually plugged into the wall, but the smoke alarms themselves can be wireless.
If you have a monitoring company and want it to be alerted when a possible fire may happen, your options may be limited. Talk with the company to find out what products work with their systems. In some cases, you may need to buy or lease your wireless smoke alarm directly from the company. On the other hand, your monitoring company may allow you to use another vendor.

What Is a Wireless Alarm Dialer?

A wireless alarm dialer is programmed to contact any saved telephone numbers, via a cellular signal, in the event that the home security system is triggered. Devices can store multiple numbers, including cell phones and office numbers, and contact them with a voice or numeric message. Homeowners can program the system to contact them if an intruder enters the house, or if their children are merely arriving home.

Auto dialing devices typically require a land telephone line to operate. The machine is connected to a standard telephone jack and wired to the home security system. The auto dialer then uses the line to dial out, similar to placing an outbound call. A wireless alarm dialer is useful for homes that do not use a land telephone line, or as an emergency back-up in case the land lines are down or have been cut. These systems can use a local cellular tower to place the call and contact any emergency stored numbers.

A wireless alarm dialer can be added to virtually any security or sensor detection system, and can typically be installed by the homeowner. Consumers may first wish to read the model specifications on the device they are purchasing to guarantee the two units will work together. They should also check the power voltage requirements for the unit, which can determine whether the model is compatible with the existing alarm system and electricity provisions of the home. Some units are also equipped to revert to a backup battery supply in the event of a power failure.

Each device can be programmed to broadcast a pre-recorded voice message or a numeric pager message. If a phone is busy or out of service when the system attempts to call, the wireless alarm dialer can be set to continue calling until the line picks up the message. It can also be programmed to move on to the next phone number, depending on the reason for the call, so that emergency situations and home invasions can be attended to immediately.

Some wireless alarm dialer devices feature a two way communication system. Using a built in speaker, the person in the home who has activated the system can communicate with the dialed individual on the other end of the line. This is beneficial for elderly and handicapped individuals who may be able to set off the home alarm system in the event of an emergency easier than they could dial a telephone for help. Systems that have been installed in such homes can also be equipped with remotes that include a panic button.

What Is a Home Door Alarm?

A home door alarm is designed to be placed on doors in homes to provide security by alerting the residents that the door is being opened. When a door with an activated alarm is touched, the alarm sounds at 110 or 120 decibels. That sound level is loud enough to be heard throughout most homes. There are many different types of home door alarms and the prices range from as little as $6 U.S. dollars (USD) to more than $100 USD. Many of the door alarms available today are wireless.

The keypad type of home door alarm is usually meant to be mounted on the wall near the door, and a code number activates and deactivates the alarm. Other kinds of home door alarms are portable and don't mount onto the wall. Some alarms hang directly on the door knob and emit a siren like noise if the door knob on the other side is touched. This type of home door alarm is made to take along when traveling, such as to use on a motel room door for extra security. Some hanging door alarms can also be carried as a personal alarm.

Doorstop home alarms look similar to an actual door stop device, as they are wedge-shaped and are placed with the narrow part under the bottom of a door. If the alarm is set when the door is opened from the outside, the alarm sound will be triggered. Another type of home door alarm is made specifically for home swimming pool gates so parents can be alerted if a child is near the water. There are also home door alarms created for use on sliding glass patio doors. Part of the alarm usually needs to be bolted to the frame, while the other part fits onto the door itself.
A home door alarm may be used not only to keep burglars out, but to keep people in the home for their own safety. For example, a small child may wake up before his or her parents and try to open a front or back door and go outside. If the parents have alarms set on the doors that they can hear and that will wake them, a dangerous situation may be prevented. This also may work in the case of Alzheimer's patients who often become disoriented and may try to wander out of a home in a confused state.

How Do I Choose the Best Wireless Window Alarm?

The first thing to look for when buying a wireless window alarm is ease of installation. Most wireless alarm systems are relatively easy to install, though some can include complex directions. Aside from user-friendliness, a wireless window alarm should operate based upon battery power. Since the point of a wireless window alarm is to avoid wiring of any kind, avoid alarms that are not battery-operated.

In addition to seeking a wireless window alarm that is battery-powered, make sure that the alarm you choose doesn't require unusual batteries. Most wireless alarms include standard AA or AAA batteries, though some may include lithium ion batteries or other, more expensive, options. Many wireless window alarms can be activated and deactivated by accessing a control panel or box. For an alarm that's simpler to use, consider a remote activated wireless window alarm.

Purchasing an alarm that can be controlled via remote is a simple and effective way to activate and deactivate your alarm system. Again, look for a remote system that relies upon standard batteries. Some remote-controlled alarm systems may even come with rechargeable batteries, which are often preferred over regular batteries.

Another factor to look for when purchasing a wireless alarm is voice notification. When activated, some alarms project vocal warnings to intruders. Generally, expensive alarms combine both vocal warnings and flashing lights, while inexpensive alarms may only include vocal notification. Both types of alarms are effective, though some people prefer voice activation over visual activation.

While wireless alarms work very well in most circumstances, sometimes interference can block an alarm signal. Prior to purchasing any kind of wireless alarm, survey the area around your home. Trees, mountains, and large obstacles may present wireless communication problems. If the area that you live in is surrounded by possible obstacles, it's a wise idea to purchase a stronger wireless system. To find out if an alarm system is capable of crossing interference barriers, contact various alarm manufacturers. In some instances, a wired alarm may be a better option.
Lastly, placement ability plays a large part in determining which alarm to purchase. Some alarms must be placed precisely. These alarms will not function if they are placed in an angled area or on a surface that is not completely flat. Take a look at your current windows. If the trim around your window is ridged, make sure to purchase an alarm that can be placed at any angle. Considering all of the details mentioned in this article is the best way to choose an alarm system that will work perfectly with your windows.

Wireless Home Alarm System

A wireless home alarm system is a home alarm system in which the various components of the system are connected without the use of wires and do not require hard-wiring to function. Both hard-wired and wireless home alarm systems generally work in the same way and consist of similar components. There is a main console that is the “brain” of the entire system. The user is able to interact with the system through a control panel, which is usually located separately from the main console.

Sensors are installed on doors and windows that are possible points of entry. Sensors consist of two parts, with one part installed on the door or window itself and the other part installed on the door or window frame directly opposite of the other half. When a door or window is closed, the two halves of the sensor create a complete electrical circuit. When a door or window is opened, the electrical circuit is broken, which triggers an alarm to sound.

Some alarm systems may also include motion detectors. As the name suggests, motion detectors trigger an alarm when motion occurs in the area being monitored by the detector. If an intruder were able to enter a home through a window or door without setting off the alarm, the motion detector serves as another method of detecting an intruder.

Alarm systems that are monitored not only sound an audible alarm at the property itself, but alert a central monitoring service of a possible break-in. Depending on the type of service that a homeowner subscribes to, the monitoring service may contact the homeowner and police, fire and emergency services when an alarm is triggered.

A hard-wired system connects the main console, control panel and all door and window sensors through a system of wires. For aesthetic purposes, the wires are installed inside the walls of a home. While wired systems have a reputation for being more reliable and effective than wireless alarms, the need to install wires inside the walls often motivates homeowners, who are installing an alarm system after a home is built, to choose a wireless home alarm system.

In a wireless home alarm system, the components communicate with the main console by sending information over radio frequencies. The technology behind this is similar to that used in cordless telephones. In the past, many wireless alarms operated on the same frequencies as cordless telephones, which could potentially interfere with the proper functioning of the alarm. Most newer generation wireless home alarms operate on frequencies not used by cordless phones or other wireless devices.

Because there are no wires connecting the components, wireless systems do offer homeowners more flexibility to make changes than hard-wired systems and are easier to install. A disadvantage of a monitored wireless alarm system is that it may only work with a specific company’s monitoring service. If a customer decides to switch alarm monitoring services, he will, in all likelihood, need to acquire new equipment that is compatible with the new alarm company's service. A factor that the homeowner considering a wireless home alarm system should consider is the price. Wireless systems are typically more expensive than a comparably equipped hard-wired system.

The first home alarm was invented by Edwin Holmes in the late 1850s. He created an electric alarm system that connected the doors and windows of a home with a bell. When a window or door was opened, a bell would ring, alerting those in the home of the opening of the window or door.

Holmes' company also developed a monitoring system for subscribers. Homes were connected to a central monitoring location electrically and when a sensor was triggered, the central monitoring location would be notified.

What Is a Fire Alarm Control Panel?

A fire alarm control panel is an electric panel that displays the location of fire equipment throughout a building. This includes the locations of smoke detectors, fire alarm switches, and sprinkler systems. The control panel is an advanced form of fire protection that is often used in commercial buildings or hotels.

It is important to have adequate fire protection in a home. This typically includes smoke detectors and fire extinguishers. Commercial buildings also use sprinklers and fire alarms to help protect the occupants. The fire alarm control panel is a centralized panel that monitors the fire alarms and safety equipment throughout a building.

A control panel is a moderately priced security device for a home or building. This device can also be used as a main security panel to detect open doors and windows in a structure. The control panel is the main hub for all security devices connected throughout a building.

Commercial buildings use a fire alarm control panel to determine where a fire is in a building. This panel is a large map of the building that uses flashing lights to represent fires. When a fire alarm is pulled or a fire is detected, the control panel lights up at the area of the fire. This helps management and first responders determine where to send emergency personal. The control panel is also useful to help an ensure an evacuation route is clear of fire.

Several types of control panels are available. These range from simple smoke detector panels to more advance multiplex systems that can automatically phone the fire department when a fire is detected. The most advance systems are typically used in large malls, commercial buildings, and department stores. These complex modules must comply with the safety rules required for public buildings.

The fire alarm control panel is normally located in an area of the building that is closely monitored by security and building management. This helps ensure alarms are reported to the necessary personnel as quickly as possible. Once an alarm is confirmed, the building management executes the necessary notification and evacuation procedures.

A qualified professional typically installs this equipment. The fire alarm control panel is connected to the alarms and smoke detectors in a building through special switches and wires. These switches send off electric signals to the control panel when a fire is detected. Installing this device requires experience with electronics and basic fire alarm switches.
