Intruder Alarm Systems We Design & Install

Not every property needs the same response path. We match detection coverage, signalling, and monitoring so you get effective protection without paying for features you will never use.

Core

Bells-Only Systems

Audible sirens that deter opportunistic crime and alert neighbours. Ideal for lower-risk homes and small premises where local alarm response is enough.

  • Internal & external sounders
  • Door, window & PIR coverage
  • Simple keypad operation
  • Cost-effective entry protection
Popular

App & Speech Dialler

Instant notifications to your phone when a zone activates — arm, disarm, and check status from anywhere. Perfect for busy homeowners and small businesses.

  • Push & SMS-style alerts
  • Multi-user app access
  • Part-arm night modes
  • Optional dual-path signalling
Advanced

Monitored & Police Response

Professional Alarm Receiving Centre (ARC) monitoring with graded systems suitable for insurance requirements and police response where criteria are met.

  • 24/7 ARC monitoring
  • BS EN 50131 graded design
  • Confirmed activation pathways
  • Insurance-friendly specification

End-to-End Service

From Survey to Armed & Ready

SAFECORE manages the full alarm lifecycle so your system is designed around real entry points, installed neatly, and easy for everyone who needs to use it.

Request a quotation

Site Survey & Grading

We assess doors, windows, stock areas, and out-of-hours risk, then recommend Grade 2 or 3 coverage, zone layout, and the right signalling path for your insurance and lifestyle.

Supply & Installation

Control panels, keypads, detectors, and sounders installed by experienced engineers with tidy cable routes, secure mounting, and minimal disruption to your day.

Programming & Zones

Entry/exit times, part-set night modes, user codes, and zone naming configured so the system matches how people actually move through the building.

Training & Handover

We train key holders on arming, disarming, bypassing zones, and app use — with clear handover notes so new staff can learn the system quickly.

Monitoring Setup

Where required, we arrange ARC signalling, dual-path connectivity, and confirmed-activation pathways so monitoring works reliably when you need it most.

Integration & Upgrades

Link alarms with CCTV, access control, and fire systems — or modernise legacy panels with app connectivity and smarter detection as your needs grow.

Detection Technology

The Right Sensors for Every Entry Point

Effective alarms start with correct device choice and siting — not just more detectors. We select hardware that cuts false activations while covering real risks.

Door & Window Contacts

Magnetic contacts on external doors, fire exits, and vulnerable windows for immediate open-circuit detection.

PIR Motion Sensors

Passive infrared coverage for rooms, corridors, and open-plan spaces — dual-tech options where pets or draughts are a concern.

Glass Break Detectors

Acoustic detection for shop fronts, glazed offices, and atriums where contact sensors alone leave gaps.

Shock & Vibration Sensors

Detect forced entry attempts on doors, shutters, and windows before an intruder fully breaches the building.

Keypads & Key Fobs

Wall keypads, wireless fobs, and app control so authorised users can arm and disarm quickly without shared master codes.

Sirens & Signalling

Internal sounders, external bells/strobes, speech diallers, and dual-path ARC signalling for reliable alert delivery.

Always in Control

Arm, Disarm & Get Alerts From Anywhere

Modern app-connected systems put status, history, and notifications in your pocket — so you know if the building is set, and who last used the system.

  • Push notifications when zones activate
  • Remote arm / disarm for trusted users
  • Part-set night modes for living areas
  • User codes and activity logs for accountability

Why Invest in an Alarm

Deterrence, Detection & Rapid Response

A well-designed intruder system does more than make noise — it changes behaviour, protects stock and people, and gives you a clear escalation path when something is wrong.

Visible external sounders and professional signage deter casual theft. Intelligent zoning and dual-tech sensors reduce nuisance activations. App alerts and ARC monitoring mean the right people know quickly when a genuine event occurs.

We also advise on insurance expectations, key-holder procedures, and how alarms work alongside CCTV and access control for layered security that is practical every day.

Crime Deterrence

External bells and system branding that make your site a harder target.

Instant Awareness

Know within seconds if a door, window, or zone is breached.

Insurance Support

Graded designs that help meet commercial insurance conditions.

Peace of Mind

Sleep better knowing the building is set and monitored properly.

Common Questions

Intruder Alarm FAQs

Straight answers to the questions we hear most often from homeowners, facilities managers, and business owners.

Do I need a monitored alarm or is bells-only enough?

It depends on risk, location, stock value, and insurance requirements. Bells-only deters and alerts neighbours; app-connected systems notify you instantly; ARC monitoring adds professional response pathways. We recommend the right level after a free site survey.

What is the difference between Grade 2 and Grade 3?

Under BS EN 50131, Grade 2 is typical for many residential and lower-risk commercial premises. Grade 3 is for higher-risk sites where attackers may be more skilled or determined. We specify grade based on your environment and insurer expectations.

Can I control the alarm from my phone?

Yes. Many modern systems support secure mobile apps for arming, disarming, and receiving alerts. We set up user accounts, show key holders how to use the app, and help keep access controlled.

Will the system work if the power or internet fails?

Quality systems include battery backup on the panel and devices. For monitored systems we often recommend dual-path signalling so alerts can still reach the ARC if one communication route fails.

Can you upgrade my old alarm panel?

Often yes. We can replace ageing panels, add wireless sensors, introduce app connectivity, or redesign zones for better coverage — sometimes reusing suitable cabling to keep costs sensible.

Do you cover Sussex and the wider UK?

Yes. We install and support intruder alarm systems across Sussex and further afield across the UK. Contact us with your postcode for availability and lead times.
