Intruder alarms in Belfast, in short

Local knowledge
Alarms that fit Belfast's housing and business stock.
Belfast is not one type of building. South and east Belfast are full of Victorian and Edwardian terraces with rear entries onto shared alleyways and plaster nobody wants a chase cut into for cable. Wireless Pyronix and Texecom kits suit these houses well, with door contacts front and back and shock sensors on ground floor windows, fitted in a morning without lifting floorboards.
The city centre and areas like Titanic Quarter have a different housing stock again, mostly newer apartment blocks with shared communal entrances and management companies. Here the alarm has to work around a front door that is not really yours to drill, so we lean on internal sensors and app control rather than an external bell box that needs the block's permission.
Commercial premises follow the same split. Shops on the main shopping streets want a visible external sounder as a deterrent and separate codes for staff, while offices and units around Boucher Road and the docks often want the alarm tied into out-of-hours access so a keyholder gets an alert the moment a door opens after closing time.
- Wireless door contacts and shock sensors for terraced houses with period fittings
- Internal sensors and app control for apartments where the front door is shared
- Staff opening and closing codes for shops and offices
- External sounders where a visible deterrent suits the premises
- Hybrid systems that mix wired and wireless where a building has both
Why Belfast properties get alarmed
What actually drives the call to us.
Most enquiries in Belfast fall into a few patterns. A terraced house wants the back door and ground floor windows covered without turning the job into building work. A landlord with a rented flat wants a simple system a tenant can arm and disarm without training. A shop or office wants staff to set the alarm on the way out and get a phone alert if anyone opens up outside trading hours.
Sites on the edge of the city, and units on business parks, tend to ask for a wider spread of detectors and an external sounder visible from the road or the yard. In every case the survey decides the mix of door contacts, motion detectors and sounders, not a standard package.

Intruder alarms in Belfast, your questions.
Answers for terraces, apartments, shops and offices citywide.
How much does an intruder alarm cost in Belfast?
There is no set price list. A free survey looks at the doors, windows, wired or wireless preference, and any monitoring, then you get a written quote itemising everything with no obligation.
I already have an alarm from another company, can you take it over?
Often, yes. If the panel and detectors are in reasonable condition we can service, extend or reprogram them, and we will say so honestly if a replacement makes more sense.
How long does an alarm installation take in a Belfast property?
A typical terrace or apartment is finished in a day. Larger shops or offices with more openings take longer, and we give a realistic time on site with the quote.
Will the alarm be set off by my cat or dog?
Not if specified correctly. We use pet-friendly detectors set to ignore the weight and movement of most pets, and we ask about animals at the survey so sensors are positioned correctly.
Can I check and control the alarm from my phone?
Yes. App-connected panels let you arm, disarm and check the status of your property from your phone, and send a notification if the alarm is triggered or a door is opened.
What happens to the alarm if the power goes off?
Pyronix and Texecom panels include a battery backup that keeps the system running through a power cut, so you do not lose cover just because the electricity does.
Do you monitor the alarm or call the police if it activates?
The alarm sounds and sends an app notification the moment it is triggered. Ongoing monitoring is an option we can discuss at the survey if you want a third party watching the system too.
Is your alarm insurance approved?
Our installers are fully qualified and every job carries comprehensive public liability insurance. If your insurer has a specific requirement, tell us at the survey and we will confirm what the system can meet.
I rent my property in Belfast, can I still have an alarm fitted?
Yes, with the landlord's agreement. We fit simple wireless systems into rented houses and flats, with clear instructions so a tenant can arm and disarm it without training.
Which parts of Belfast do you cover?
We cover all of Belfast, from south and east Belfast to the city centre, Titanic Quarter, Boucher Road and the docks, along with the surrounding towns listed below.
Do you offer aftercare once the alarm is installed?
Yes. We remain available for servicing, adding extra detectors or user codes, and technical support, whether the alarm is new or one we have taken over from another installer.
