Homeowners have the choice of house alarm. 

During the building boom in Ireland most new properties had the alarm wiring fitted during construction phase, however it is becoming more common nowadays to construct new properties without the alarm wiring. In a lot of cases the customer must decide if they would prefer to have the alarm wiring fitted for the purpose of installing a new alarm system or choose to install a wireless alarm system. There are many factors to consider when choosing to install a wired or wireless system. Homeowners should carefully study the pros and cons associated with both types of systems before reaching a final decision. 

There are many factors to consider when choosing a wired or wireless system. 

Disruption to the home 
 
A wired system involves making holes in the properties structure in order to fit the appropriate wiring that is required. While, if carried out by a professional installer, will be completed to an acceptable standard, disruption such as this plus possible structural damage is completely eliminated if a wireless system is installed. Installation of wireless systems is virtually mess free with no wiring necessary. In addition, wireless systems are very versatile and adaptable to almost any type of premises. 
 
Time 
 
In general a wired system will take twice as long to install over wireless. A wired system can take from a minimum of 1 day and up to 2, 3 or more days depending on the size of the premises. A typical wireless system will take just 2 – 4 hours to install. 
 
Portability 
 
One major advantage of installing a wireless system is its portability. Should you move home or if your company moves premises you can take your system with you, with it taking only 1 hour to disconnect and remove the system it is so handy! This is not possible with a wired system. 
 
Battery replacement 
 
There are two back up batteries in a wired system. One battery is located in the main control panel to back up the system should the power go off in the property. The other is located in the external alarm box. Both batteries will need replacing every 3 – 5 years. There are batteries in every component that make up a wireless alarm system. You must allow for replacement of all batteries every 3 – 5 years. If you have a relatively basic system this may not be a factor you need to consider, however if you have a large system the costs can add up! Both systems will give you about 1 months notice for a low battery. 
 
Equipment cost 
 
Wireless alarm equipment is definitely more costly with it generally coming in at three times the cost of wired alarm equipment. 
 
Interference 
 
In times past some people may have experienced interference on their wireless system from baby monitors, however since the new EN wireless standard was introduced all security equipment now has its own dedicated frequency (868.4 mhz). Interference is not a problem for either system. 
 
Tamper protection 
 
Thankfully, both systems will alert you via the keypad if your alarm has been tampered with i.e. phone lines may have been cut in order to disable your alarm monitoring service. 
 
Some skeptics think that wireless systems can be easily disabled, this is not true! All systems must operate in accordance with EN 50131-1 standards which provides full 24 hour anti tamper protection on all equipment. If an attempt is made to try to disable either system an alarm activation will occur, with the alarm ringing loud and a tamper alert displaying on the keypad you can be sure that a disable attempt will be spotted! 
 
Future expansion 
 
Future expansion of a wireless system over time or as the budget permits is really simple. You can add / remove as few or as many devices as you feel necessary. Key fobs, panic buttons, motion sensors, vibration sensors, door and window contacts, alarm monitoring modems, smoke, heat, gas plus CO detectors are just some of the wireless devices that can be added with ease. These devices can even be fitted in out buildings with no wiring necessary. Of course, all of these devices can be added to a wired alarm system also, however the wiring must already be in place or it must be possible to install the wiring to each device location. 
 
Which system is the safest? 
 
Both systems are equally safe once fitted in accordance with standards!
