Installers

Age old questions abound, which could cause a constant series of debates. Which is better, Chevrolet and Ford, Coors and Budweiser, winter or summer?

Ask some guys who is the best alarm system, wired or wireless, and certainly some opinions strong enough to support one or the other for receiving. Battlelines drawn in length, will try to the bottom of this problem are clearly divided.

Wired alarm panels are less expensive than Wi-plates, but are more difficult to install. KeepDone in this way, if you plan to install itself. A facility average home with a hard-wired system takes about 12-16 hours. A typical wireless installation takes less than 4 hours.

Another consideration is that some types of construction are suitable for cable installation, and others require the use of wires. Normally, all the alarms are connected to trade, and a large percentage of residential use wireless systems.

EvenIf you buy a wireless alarm panel, many systems require that some of the devices are wired. These typically include power transformer, electrical grounding, telephone and all keyboards / fitting stations, and audible alarms. There are some exceptions to this, some of the latest all-in-one units currently being offered, the base unit, the station arm and audible alarm to take a unit that plugs into your existing phoneJacks.

The main difference between a hard-wired and wireless alarm panel, as all connected devices to communicate with system security. A jury will require a wired network a thread for each "zone" or the device on the system, while a wireless system, a radio frequency, using the "zone" or devices that are connected with communication.

While a normal electrical circuit is a parallel circuit, a circuit typical hard-wired alarm system is a 2-wire usually with closed-loop endSupervision of the line commonly referred to as a series circuit.

A series circuit allows power flow back from the alarm panel, provides a wire from the alarm device and initiate the alarm panel. When the power is interrupted, the group recorded a fault on the line / area. End of line (EOL) resistors are added to the line so that the alarm panel to monitor the condition of the area for earth faults, short circuits and open lines or trim.

SeveralNC devices can be connected to a single patch installed by connecting devices in series with the EOL resistor at the last device in line. In this way, the entire circuit will be completely controlled by the panel is the last device in line.

If the wireless alarm systems first appeared on the market, were not the most reliable system. Most of them are not used under the supervision of wireless transmitters that communicate with each field device. A non-wireless controlSirens would only be a signal "one way" to the receiver alarm panel when activated.

For example, if a door or window is opened, the transmitter sends a wireless signal. The alarm panel should receive the signal and activate the appropriate zone. The transmitter would not be a signal if the door or the window was closed, so that the receiver / reset area was within a few seconds. With a non-controlled wireless system that you are really an arm of the system withDoor or window open, without knowing it.

Most of the new alarm systems use a redundant connection for bidirectional fully supervised wireless two-way communication between the sender and the recipient of the alarm panel. With fully supervised wireless alarm panel can have the real-time status of the door or window. If a door is open, it will be accused of maintaining the area until the door is closed.

Most of the early wireless systems were very limited in the treatment systems.Have this dip switches with binary address (below), Member distinguish between the points of the system.

He was fine, if the wireless system was installed and commissioned, but what happens if your neighbor installed the same type of system? If the motion detector close to the recipient the garage door went away the alarm every time he went to his house. As you can imagine, this could cause some major problems that were very difficultTo solve.

Modern wireless systems using the serial numbers of binary codes or other proprietary technologies ensure that only the stations are listed in the panel will be received by the alarm system. When you do your research and to supervise the purchase of a good, reliable alarm system, you should know never have to worry about your neighbor's wireless transmitter crediting the alarm system.

Another problem with the older non-monitored systems is that you do not know whenBatteries for transmitters with low or need to be replaced. The only way to ensure that they work, must be tested regularly.

Even the most sophisticated wireless alarm panels are useless if the transmitter battery died, so wireless monitors are programmed to panels, each remote station, at least once every 24 hours. If the transmitter has a low battery, the keyboard / arming station immediately inform the problemCondition.

Regularly with a portable system of security that should always make the system performance. The range of wireless products for the environment and structure that is interested in be installed. In addition, the offer may be influenced by environmental conditions, defects in the form of electrical or orientation of the transmitter in relation to the recipient.

Who is the winner of this topic? Well, according to UnderwritersLaboratory (UL) to use the methods are safe and reliable installation of wired end of line (EOL) 1 or 2-resistance surveillance. In fact, the installation UL for the federal government and other high security require that all systems are connected to areas of protection, with 2-line monitoring of resistance.

Not to say that wireless systems are an inferior product. In fact, fully monitored systems offer very good protection, is the perfectsuitable for 90% of plants currently exist.

If you prefer a wireless alarm system into consideration, be warned, there are still sold and installed today's systems that are not controlled, so as to ensure that whatever system you are planning to offer a complete wireless monitoring.

If you opt for a hard-wired alarm, please be sure, that the system is installed with the supervisors to line resistance. To make installation faster and easier, some plumbersresistances in the position alarm panel, not the end of the line.

Although this method provides for the supervision of the area for earth fault, it means no protection for a short, direct or, worse yet, someone spliced the wire and shorted together, which essentially close the loop, the panel has not seen to open or close the area.
