If you have a lot of valuables, insurance companies may insist that you fit a burglar alarm, and take other security precautions. These rules DIY alarms, since they will almost certainly insist on an alarm installed on the BS 4737 includes a provision for the installation of the company inspected regularly. Companies that are registered with the National Supervisory Council for Intruder Alarm (NSCIA) guarantees for installation of this standard.
Before installing a burglar alarm, you should consider the advantages and disadvantages of having one.
On the plus side is that you have a visible deterrent to would-be burglars, the alarm goes off can stop a burglar getting into, or reduce the time it stays around if he does not get in. There may also be an advantage in protecting a window alarm burglar, but lock, so you can get out quickly in case of fire. And for people who live alone - either elderly or persons with special needs - has the added advantage of being able to attract the attention of many panic alarm could raise the alarm if someone try to push their way through the front door.
On the minus side of embarrassment to activate or deactivate the alarm, and the costs and problems with false alarms. And if you live miles from anywhere there May be no one to hear the audible alarm.
Burglar alarms that you can install yourself to break into four groups: wired systems, wire-less systems, door alarms and motion detectors. You can also get different types of security lighting.
Wired-in systems
This is probably the most common type of DIY burglar alarm. "Kit" consists of three main parts:. Series of detecting devices, a warning device (horn or bell) and the control panel
Detection devices
Detection devices of this type of system will usually be there to respond if someone opens a window or a door connected to the system. Magnetic contacts will cause the alarm to sound if the circuit is broken: the neatest and most efficient smooth lilting (such as mortice locks), a surface-mounted contacts are easier to install and May will be the only option on the double doors and metal framed windows. Pressure pads are built into carpels (in front of hi-fi or under one of the steps of the stairs) and will cause an alarm to sound when he trod on den. Most DIY alarm systems have a manually operated panic button (or a personal attack button) that is embedded in the bed or on the front door and that will set oil 'alarm (even if the system is disabled), if you press the button (can be returned only with a key ). Little do-it-yourself wire systems include motion detectors, but they usually can be added as an extra.
Warning Device
Warning The device is usually ear-piercing bell or horn within a fixed wall on an elevated part of the house. They are designed to sound for no longer than 20 minutes (by law), some systems incorporate a flashing light and that will go on device typically has its own battery, which will cause it to act in case of power or wires are cut. Usually you can buy a 'dummy' case the bell as extras to put on the other side of the house. Most systems can be equipped with an internal alarm that goes oil 'just before the main alarm.
Professionally installed systems can also have remote dial a phone where the call is usually made at the central monitoring station when someone breaks in, before sounding the alarm. This property is expensive.
Control Panel
This is the heart of the system and is usually the key operates a switch system and oil. "Most of the system has a delay built in, so you have time to get through the front door, without selling off the alarm, some have different zones, so you can protect different parts of home. Perhaps, for example, want to be down only protected during the night.
The control boxes are usually network drive (rechargeable) battery back-up, and there are many indicators that are part of the run. There is usually a lab, so you can ensure the system works properly and, as well as external devices alert boxes are equipped with tamper protection, so that the alarm will sound if someone tries to take the front of the box.
Wiring a do-it-yourself system is quite simple: the hard work hidden wires and fit ¬ ting flush-mounted magnetic contacts. Wiring up contacts and a control box may be seeking, to wire the warning device will probably need to do to systems use four primary and six-core wire detection devices, which means that the alarm will sound if the wire is cut .
The alarm itself is connected to the low voltage cable, but the panel usually need electricity meter connected to the network through the terminal unit. If you are in any doubt about this part of the job, call an electrician.
Wire less system
Wire-less system has components similar to conventional wire-in do-it-yourself burglar alarm system, but communication between different parts of it via radio waves instead of electricity. This means that no wire is needed (except between detection devices and their transmitters) and the control panel can be located anywhere in the house and moved around, if you want. Control panel to set the key and tells you if some system components are not secured before setting the alarm, and will indicate where the break-in can be divided into zones and includes a portable emergency transmitter, infra-red transmitter to detect movement can be used as magnetic contacts, and pressure pads. The system is very easy to add and may also include remote dial ling the building, but it is very expensive.
Door alarms
Instead of centrally controlled alarm system you instead to fit a particular battery-operated alarms for doors and windows that are in danger. This makes the system much easier to install.
Most door alarms depend on the movement of the door alarm is set or with a wrench or overlap in their personal code to Alarm can be set to 'time' (when) or "delay" in order to allow time to be in and out. Some door alarms have an extra 'Visitor' setting that gives the chime or grit when the door is open.
Many of movement detectors are disguised as household items such as hi-fi speakers, but will leave a piercing noise if someone enters the room to protect it.
Some motion detectors can be connected to external alarms, and some may be involved in a whole-house system alarm system.
Security lighting
There are basically two types of security lighting can fit into your home. The first uses a security light switch that you fit in place of ordinary Lightswitch (after turning off the power). This type of switch will turn controlled lights on and off according to the program set to prekidač.Bočno light can also be turned on and off easily switch to the outlet that feeds the light.
Another type of security light is mounted on the outside and managed by infra-red sensor, or included in the light or mounted separately. Exterior lights, especially powerful ones, are good burglar deter ¬ rent, and one that comes automatically tend to be shy. This light is easy to wire, requiring only connection to the fused connection unit inside the house with perhaps additional wiring if one detector includes more than one light.
