A couple of things we see every week. One of our most common call-outs is a new homeowner who's bought a house with an existing alarm and no codes — we attend, create your codes and test everything. And most "false alarms" turn out to be a motion sensor left on maximum sensitivity, which is usually fixable remotely.

Low battery warnings, tamper alerts, or zone faults causing annoying beeping sounds

Alarm Repair FAQs
How quickly can you repair my alarm system in Perth?
We prioritise alarm repair bookings. For urgent faults, call us directly on 0413 346 978 and we'll advise on the earliest available time. Our technicians carry common parts and can diagnose and fix most alarm faults on the spot.
What types of alarm systems can you repair?
We repair all major brands including Bosch, Risco, DSC, Paradox, Hills, Ness, Texecom, Ajax, and more. We service both wired and wireless alarm systems for homes and businesses across Perth.
How much does alarm repair cost in Perth?
Alarm repair costs vary depending on the fault. We charge a service call-out fee plus parts and labour — we provide upfront quotes before starting any work so there are no surprises. Contact us to discuss your issue.
We'll also tell you when a repair isn't worth it. A water-damaged panel is a good example: even a successful fix invites the same failure, and at that age you're usually looking at new hardware anyway.
Do you offer alarm system maintenance?
Yes, we offer regular alarm system servicing and maintenance packages to prevent faults before they occur. Annual servicing includes battery replacement, sensor testing, and system health checks.
Can you repair alarm systems installed by other companies?
Absolutely. We service and repair alarm systems regardless of who installed them. With 21+ years of industry experience, our technicians can work on any brand or model of security alarm system in Perth.
My alarm keeps beeping - what should I do?
Constant beeping usually indicates a low battery, tamper alert, or zone fault. Try entering your code to silence it. If it continues, call us for diagnosis. Don't ignore it - a faulty alarm won't protect your property.
Do you provide emergency alarm repair?
Yes, we prioritise urgent alarm faults. Call us on 0413 346 978 and we'll advise on the earliest available attendance time.
