About this service
An intruder alarm detects unauthorised entry using door contacts, movement detectors, shock sensors and other devices connected to a control panel or wireless hub. The system should suit the property layout, pets, user routines and desired notification or monitoring.
A dependable alarm is easy to set and unset, has suitable backup power and avoids unnecessary false alarms. Device quantity alone is less important than sensible coverage and commissioning.
Common problems we help with
Frequent false alarms
Pets, open windows, device position, low batteries and user errors can cause unwanted activation.
Entry route is awkward
Keypads, delays and part-set arrangements do not match how people use the building.
System shows tamper or battery fault
Covers, cables, backup batteries and wireless devices need checking.
No remote notification
Older local-only systems may need an upgrade or communicator where appropriate.
How we carry out the work
Review entry points and routines
We identify perimeter risks, internal routes, pets, outbuildings and part-set needs.
Choose wired, wireless or hybrid equipment
Coverage, maintenance, aesthetics and existing cables shape the system.
Install, commission and train users
Zones, codes, alerts and backup operation are tested with practical user instruction.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed intruder alarm systems work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- The building layout, escape routes and areas that genuinely need coverage
- Who uses the system and how alerts, entry or routine tests will be managed
- Cable routes, power supplies, networking and resilience during an outage
- Ongoing testing, maintenance and record-keeping requirements
What affects the price?
The price depends on the existing installation and the amount of work required. For intruder alarm systems, the main factors normally include:
- Device and detection-point quantity
- Wired, wireless or hybrid infrastructure
- Access at height and containment requirements
- Monitoring, recording, integration and maintenance options
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- System demonstration for the people who will use it
- Device, zone or camera schedule as appropriate
- Test results and commissioning information
- Maintenance and routine-user-check guidance
Intruder Alarm Systems questions
Can pets stay in an alarmed property?
Pet-tolerant detection and perimeter devices may help, but animal size and movement areas need careful planning.
Will it work in a power cut?
Control equipment normally has backup power for a limited period. Battery condition must be maintained.
Can an old wired alarm be upgraded?
Often, existing sound cables can be reused with compatible or hybrid equipment after testing.
