Burglar Alarms in County Down, SSAIB certificated Installation
We design, install and maintain SSAIB certificated burglar alarm systems for homes, businesses and farms right across County Down, from Downpatrick and Newcastle to Comber, Newtownards, Bangor, Banbridge and Newry. Every job starts with a free survey and ends with a fixed written price, so you know the cost before anything begins.
Free, no obligation. We survey, you decide. Thousands of premises secured since 2017.
Three kinds of premises, three different alarm designs
County Down is not one place. A shop unit on Market Street in Downpatrick, a family home on the Ards peninsula and a farm yard outside Ballynahinch face different problems and need the detection put in different places. We survey the building first and design around it, rather than fitting the same kit everywhere. See every area we cover across Northern Ireland.
Business and Retail Premises
Shops, offices, workshops and hospitality sites across County Down usually have the same weak point: a secure front and a back of house nobody watches once the shutters go down. We zone the system so you can set the yard, the stores and the roof access separately from the trading floor, and so a cleaner or an early delivery does not force somebody to unset the whole building. See our Bangor burglar alarm page.
Homes and Family Properties
For a house, the point is to know somebody is on the property before they are inside it. That usually means detection on the ground floor doors and windows, cover on the route between them, and a way for you to see the state of the system from your phone when you are away. We fit systems people actually set every night, because an alarm that is awkward to use ends up switched off. See our Lisburn burglar alarm page.
Farms, Yards and Rural Property
Rural County Down brings outbuildings, machinery, fuel and quad bikes, often a long way from the house and with nobody in earshot. Detection here belongs at the yard boundary and on the sheds rather than only on the back door, and it has to cope with livestock, weather and vehicles without crying wolf. We survey the whole holding and tell you honestly what is worth alarming and what is not. See our Newry burglar alarm page.
recorded offences
Police open data records 571 offences within about a mile of Downpatrick town centre between January and June 2026. Market Street, Market Lane, John Street and Saul Street come up most often. 76 of the 571 involved somebody being on a premises: burglary, robbery, criminal damage and arson, and vehicle crime.
criminal damage and arson
61 of those 76 were criminal damage and arson. Burglary accounted for four in six months. That is worth saying plainly, because it changes what a County Down alarm is actually for: far more often the problem is somebody on your property doing damage than somebody forcing a door to carry things out.
with a published result
Not one of the 76 had a concluded result recorded at the time of writing. 58 were still under investigation and 18 carried no status update at all. That is the honest case for detection rather than fear: the file stays open for a long time, so the part you can still change is whether anyone knows it is happening while it is happening.
Wired, wireless or monitored: what actually fits your building
There is no single right answer here, and anyone who gives you one before seeing the building is guessing. Intruder alarm systems are graded to suit the site under BS EN 50131 and PD 6662 rather than to one flat standard, so what your premises needs depends on the risk, the layout and what your insurer expects. Here is the plain English version of the three choices.
Wired Systems
Best where cable routes are accessible: new builds, extensions, buildings already being rewired, and larger commercial sites. Nothing to change batteries on and no radio path to worry about. The trade off is cabling work, which means more disruption and more time on site.
Wireless Systems
Best for finished houses, listed and older buildings, rented units and anywhere lifting floors is not realistic, and County Down has plenty of all four. Much faster to fit and far less mess. Sensors run on batteries that need replacing periodically, which we cover at service visits. Worth knowing that external sounders on a listed building can still need listed building consent, which is planning law rather than anything to do with the alarm.
Monitored Systems
Any of the above can be monitored. Instead of only making noise locally, the system signals an Alarm Receiving Centre certified to BS EN 50518 over a transmission path built to BS EN 50136, with signalling designed in line with BS 8243. Monitored systems can be eligible for a police Unique Reference Number through the PSNI URN scheme.
Four steps, and you can stop after the first
Free survey
An engineer walks the property with you, looks at how you actually use it and where the real weak points are. Free, no obligation, and you are not signing anything at this stage.
01
Fixed written quote
A written price for the system we have designed for your building, agreed before any work starts. No day rates that drift and no surprise on the final invoice.
02
Installation day
We fit and commission the system, test every detector and signal path, and then show you how to use it properly rather than handing you a manual and driving off.
03
Aftercare and maintenance
You get a real number that reaches an engineer, servicing to keep the system reliable, and a review of any false activations so your alarm keeps being taken seriously.

Burglar alarm questions from County Down customers
Do you cover Downpatrick, Newcastle and the rest of County Down?
Yes. We cover County Down in full, including Downpatrick, Newcastle, Ballynahinch, Comber, Saintfield, Killyleagh, Newtownards, Bangor, Donaghadee, Banbridge, Kilkeel, Warrenpoint and Newry. Our office is in Coleraine and our engineers work across Northern Ireland from there, so what you get is a certified company covering the county rather than whoever happens to be closest on the day. Call 028 7087 8077 to book a free survey.
How much does a burglar alarm cost in County Down?
It depends on the size of the building, how many areas need setting separately, and whether you want the system monitored, so we will not quote a figure blind. A three bedroom house in Downpatrick and a retail unit with a yard and stores behind it are genuinely different jobs. What we will commit to is the process: a free survey first, then a fixed written price for the system we have designed for your building, and you are free to walk away at that point having paid nothing. If the honest answer is that your existing panel can be reused and you need less than you thought, we will tell you that too.
Wired or wireless: which is right for my premises?
Both work, and the building usually decides. Wired suits new builds, extensions and anywhere cable routes are already open, and there are no sensor batteries to think about. Wireless suits finished houses, older and listed buildings, rented premises and anywhere lifting floors is not realistic, which covers a great deal of County Down housing stock. Wireless is quicker to fit with far less mess, and the sensor batteries get changed at service visits. Many sites end up with a mix of the two. We work this out at the survey rather than deciding before we have seen the place.
What does SSAIB certification, Reg. NIRE127, mean for me?
SSAIB is an independent certification body for the security industry. Advanced Overwatch is SSAIB certificated (NIRE127) specifically for Intruder Alarm Systems, Visual Surveillance Systems (VSS) and Access Control Systems. In practice it means our installations are independently audited against the relevant standards rather than self declared, which matters when an insurer or a landlord asks who fitted the system and to what specification. Many commercial insurers require monitored alarms as a condition of cover, particularly for higher sums insured or higher risk premises, so it is worth asking your insurer what they expect before you decide on a specification. This is general guidance rather than legal or insurance advice.
Can my burglar alarm get a police response?
It can, if the system is monitored and eligible. A monitored intruder alarm signals an Alarm Receiving Centre certified to BS EN 50518 rather than only sounding locally, and monitored systems can be eligible for a police Unique Reference Number through the PSNI URN scheme. A URN is not permanent. It can be withdrawn after repeated false alarms, generally three in a rolling twelve months, which is why keeping false activations down is part of the maintenance contract rather than an afterthought. A bells only system, by contrast, relies entirely on somebody nearby hearing it and choosing to act, which on a rural County Down site at three in the morning is a thin plan.
