Intruder Alarms For Your Home

When considering the purchase of an Intruder Intruder Alarm System there are some important points to consider, the first being what sort of alarm do I require?

No two houses are the same – they may be of the same design, but the owner’s requirements and expectations are always different. With this in mind, we will never provide a quotation without first surveying your property and discussing your requirements, unless suitable floor & layout plans are available and your requirements have been relayed to us.

Surveys & Quotations are free with no obligation so you have nothing to lose.

Surveys are always carried out by an installing engineer who has many years experience in what can and cannot be done. We do not use commission based salesmen, so you can be assured of a professional service and expert advice with no hard sell.

We will Design, Install and Provide a Maintenance Package to suit your requirements, detailing everything within a full specification & quotation in plain English including equipment brochures so you are aware of exactly what you are buying.

Upon receipt of your signed acceptance we will agree a suitable installation date and your system will be installed.

With many years experience, we understand that you may be concerned that having the system installed will be intrusive.
We fully respect that we will be working in your home and ensure that the utmost care is taken of your property with minimum disruption.

Our own engineers will install your system as sympathetically as possible. Concealing the system cables is our speciality.

Upon completion, your system will be demonstrated fully and handed over to ensure you fully understand the operation of your new Intruder Alarm System.

Updating an existing alarm system

If your property already has an Intruder Alarm Installed which you require upgrading or extending, we will happily visit your property and survey the existing system and discuss your requirements, this will be followed up with the provision of a written report and specification and quotation.

Upon completion, your system will be demonstrated fully and handed over to ensure you fully understand the operation of your new Intruder Alarm System.

Intruder Alarms For Your Business

Intruder Alarms for Commercial Premises are significantly different in their operational requirements than those installed within Residential properties.

Business security is vital in today’s world. Protecting your business from theft and vandalism is crucial in keeping your business fully operational without loss of time and profits.

At this time, it is virtually impossible to recover all of the losses that crime can cost a business through insurance.

Loss, such as the theft of a computer will be covered under insurance, but what of the secondary costs, such as the value of the data stored within the computer and the possible cost of customer goodwill, this kind of loss is immeasurable.

In many cases especially with older alarm systems where businesses are split into different areas or departments, not everyone starts or finishes work at the same time, this means that some parts of an office or factory may remain unprotected and unoccupied for a number of hours before the alarm is fully armed.

This does not have to be the case, as todays systems can be divided into multiple areas each having their own local keypad allowing individual areas to be armed / disarmed independently of the main system.

This not only protects from possible external crime but can prevent unauthorised people entering restricted areas of a company.

If you would like to discuss your existing security arrangements or require a new system please do not hesitate to contact us.

With over 40 years experience we are able to survey your premises, advise and design a suitable system to meet your requirements and those of your insurers where a Graded System has been specified these detail the risk level to be covered.


With over 40 years installation experience within the industry, we have always chosen our system manufacturers carefully, as installing the wrong equipment can be very costly in more ways than one not only for the client but also the installer.

The old saying…… you pay for what you get applies extremely well within the security industry.

Watson Alarms only supply and install Alarm Control Panels manufactured by HKC in Ireland

One Type Does Not Fit All.

When we survey a property prior to producing a specification & quotation a number of points are taken into consideration, some of which are – type of property, size of property & system requirements, the answers to these questions normally indicates the type of system we will be specifying.

There is still not one type of system that will suit all situations.

Wireless systems

Wireless Systems – Small To Medium Residential Properties

As the name suggests these systems communicate wirelessly and require very little cable installation, which can be of huge benefit in a property which is practically impossible to cable due to structural & decorative constraints.

Wireless systems do have their limitations where property construction can limit signal transmission, this will of course be taken into consideration at time of survey. An additional point to consider is the increased maintenance cost due to the replacement of device batteries, this however need not be the deal breaker on smaller systems.

HKCs  wireless technology delivers more performance than any other wireless security system. The size, scalability and range of the entire system are extended as wireless signalling is no longer limited by point-to-point communications. The range of  HKC enabled wireless system is greater than previous systems, with multiple devices capable of relaying messages to and from even the most remote locations in a building.

Hybrid Systems – All Properties

Hybrid Systems are basically a system made up of both Hard Wired & Wireless components, these types of system come into their own where an area within a property is impossible to cable due to building structure or decorative constraints.

By adding a wireless receiver to a compatible alarm panel up to 70wireless devices can be added.

While still maintaining the total flexibility of a hardwired system.

Hybrid Systems are extremely useful where an existing intruder alarm requires upgrading for monitoring purposes and requires sequential confirmation, a wireless receiver will allow the addition of shock sensors to vulnerable external patio & bi-fold doors.

Hardwired Systems – All Properties

Hardwired systems are fully cabled installations which are our favourites and are able to meet whatever system design is required due to their total flexibility.

Whether it is a small residential property with 5 of 6 detection devices, or a palatial new build with 60 detectors plus hardwired systems can be adapted to suit all needs.

Hardwired systems really come into their own within large residential and commercial properties where an alarm needs to protect a number of individual areas which in turn require the flexibility to enable individual areas to be armed & disarmed separately from within one main system.

We have the experience and the knowledge and can supply and install a system for you with the necessary equipment to protect any property from 1 to 640 zones.

Communication Options

Bells-Only Audible Alarm

This is generally the most basic option.

If the alarm is triggered, an audible alarm sounds to alert you – or a neighbour – that an intruder has entered (or is trying to enter) the property.

This type of system may be appropriate for most typical dwellings. However, it depends upon the location of the property. Is your property in a built-up area or within a housing development where people will hear the alarm sounding if triggered or is it in a rural location with no immediate neighbours?

Another point to consider is your lifestyle, are you away from home for extended periods? Or does your house/business contain content of high value.

For the system to be acceptable to your insurers it should always be fitted by a certificated installer to the relevant British Standards.

Monitoring & Police Response

For increased security, you may wish to have your security system monitored.

A monitored alarm is one that is linked via the telephone line or cellular network or both to an Alarm Receiving Centre (ARC)

Monitored Systems

The system installed may be the same as (or similar to) a bells-only system, except that – when the alarm is activated – an integral modem informs the Alarm Receiving Centre via a burst of data much the same as a fax tone.

Dependent upon the signal received & the design of the Intruder Alarm System the Alarm Receiving Centre will be able to confirm if the alarm condition is unconfirmed (1 detector triggered) or Confirmed (2 detectors triggered) at which time the Police are alerted.

With this point in mind, it is important that the alarm is designed correctly to ensure that should a burglary occur the alarm will trigger 2 separate zones quickly before the intruder can get to far into the property.

It is important that the monitoring centre is recognised by the Police.

A unique reference number (URN) – which identified the premises – must be obtained by the Installing Company from the Police, when the system is installed.

To get this number, the installer and the monitoring centre must be registered with a certification body – such as the NSI

Monitored systems do not guarantee a Police response.

If it is reasonably certain that someone has entered the premises, it will be flagged as a confirmed activation. However, if a system has three false alarms in a year – four in Scotland – the URN will be revoked by the Police.

To be reconnected, evidence that the problem has been resolved must be provided to the Police within three months.

Types of Monitored System

Digital Communicator

This is the most common method of signalling at this time, and communicates with the Alarm Receiving Centre (ARC) via the properties telephone line, operational costs are low, but if installed incorrectly or where the properties incoming phone line can be easily compromised this method of monitoring will be made ineffective if the phone line is cut or disabled.

DualCom Dual Signalling

The DualCom GradeShift range offers a single piece of hardware for every grade of risk with interchangeable EN Grades.

Single path options G2r and G3r utilise all mobile networks via their WorldSIM to signal an alarm and are the ideal solution where there is no telephone line available.

Dual path options G2, G3 and G4 utilise multiple signalling paths via their WorldSIM & the properties landline to signal an alarm and have been designed with the lowest to highest risk premises in mind.

You simply pick the grade required.

DualCom is trusted to protect hundreds of thousands of premises throughout Europe including many major retail brands.

Key benefits and features:

  • Multiple signalling paths on board – GPRS, LAN/IP and telephone
  • Detects signalling path failure in seconds (line cut, GSM blocking, network failures)
  • Dual signalling is preferred by insurance companies and the Police
  • GradeShift enables remote up/down grade for change in insurance specification
  • EN Grade 2/DP1 dual path signalling service
  • Polling via Gemini every hour
  • Upgrade to GradeShift UDL available
  • Multi-network WorldSIM as standard for increased reliability

DualCom DigiAir

The DualCom DigiAir utilises all mobile networks via the DualCom WorldSIM instead of a telephone line to signal an alarm from the protected premises to the Alarm Receiving Centre (ARC).

It is designed for low to medium risk premises and is an ideal upgrade for wired digital communicators as it eliminates call costs and phone charges.

DigiAir is small enough to fit into any existing or legacy control panels.

It can be supplied complete with a Compact Power Supply for installations where the control panel is unable to consistently provide 12v DC and provides a more aesthetically pleasing finish.

DigiAir is also unaffected by Next Generation Networks (NGNs).

Like all CSL products, DigiAir is supported by the Gemini Platform, a Critical Connectivity platform responsible for the integrity of hundreds of thousands of premises throughout Europe.

Key benefits and features:

  • Eliminates call costs and phone Charges
  • WorldSIM as standard to increase reliability and reduce false alarms
  • Designed for maximum panel compatibility
  • Small enough to fit into any existing panel
  • Dial Capture provided as standard
  • Fast Format, Contact ID and extended SIA
  • Unaffected by NGNs
  • Patented Technology – GB2465833
  • Can be pre-fitted to Compact Power Supply if required

WIFI CARD – App control communication

This will be a cheaper option than having a fully monitored system.

With the wifi card when the alarm is activated, the system will proceed to signal the securecomm system in Ireland and relay all communication to your smartphone audibly and by text to the alarm. If the phone line is cut or the broadband is disabled, no signal can be sent.

The APP allows for full control of your alarm system via the APP, you can bring up a virtual keypad allowing realtime live keypad controls.

The App also has a log record which can be sent via email if required

GSM-SC – World sim – App control communication

This unit uses a world sim card which roams 4 x mobile networks to ensure the communication is constant 24-7, so if you have a power cut and the alarm is running on its battery it will still send a signal to your phone. This will run on the APP system too to allow full control of the system

Dial Caller

This will dial 4 numbers of your own choice via a phoneline connection.



The range and diversity of the types of alarm that are available can make choosing the right system to meet your requirements quite complex and choosing the wrong one can prove to be costly. System Grading is very important in the case of insurance requirements, we therefore will only install systems that meet Grade 2 & above, then should your insurer require your alarm to be upgraded to Police Response costs are kept to an absolute minimum.

Grade 1 is where a lower risk of theft is anticipated. It applies to a property which is not likely to attract burglars. In the application guide (DC CLC/TS 50131-7), it assumes that a thief is likely to be opportunistic rather than planning a theft and will simply break open a door.

Grade 2 is for a higher risk level. Such a property is likely to have something of interest to an experienced thief who is likely to have some knowledge of how alarm systems operate and possibly carry some tools to help him overcome a simple alarm system. The thief is likely to check the building for easy access through doors, windows and other openings, therefore these are the principal areas of detection.

Grade 3 is for a property which is at reasonably substantial risk, one which, might well contain objects of high value so there is good reason to assume it may be broken into.
An intruder is likely to be knowledgeable about intruder alarm systems and there operation and may attempt to overcome the system.

The thief is likely to get in by penetrating doors, windows or other openings but can also be expected to gain access by penetration of floors, walls and ceilings so additional protection is required.

Grade 4 is for highest-risk properties. Such properties are likely to be targeted by a gang of thieves who will probably have planned the burglary in advance.

They will know some techniques for preventing detection or tampering with intruder alarm systems, and therefore, the levels of sophistication need to be that much greater to prevent this happening.

Mixing components of different grades

The EN standard states that an installer can use different grades of component within the same intruder system.
For example, if the installation has a Grade 2 listing, it is acceptable to use a Grade 3 power supply. However, it is not permissible to use Grade 1 components within a Grade 2 system.
