FAQ: Alarm Repairs in Auckland
When your alarm system fails, it’s not just an inconvenience—it’s a security gap in your home or business. Whether you’re dealing with a beeping sensor, a malfunctioning panel, or a complete system failure, understanding your repair options is crucial. This comprehensive guide walks you through everything you need to know about alarm repairs in Auckland.
Why Professional Alarm Repairs Matter
Your alarm system is a sophisticated piece of security infrastructure. While some issues might seem simple, attempting DIY repairs can void warranties, damage components, or worse—leave your property vulnerable to theft or damage.
At Garrison Alarms, we’ve been repairing and maintaining alarm systems across Auckland for over 35 years. Our technicians are certified and trained on all major brands including Paradox, Bosch, DSC, Micron, Hikvision, Risco, and Panasonic. We understand that every system is unique, and every repair requires expert attention.
Common Alarm Faults in Auckland Homes
1. Low Battery Warnings
What it means: Your system’s backup battery is running low, typically indicated by a beeping panel or low battery warning code.
Why it happens: Batteries degrade over time. In Auckland’s humid climate, battery degradation can accelerate. Most systems require battery replacement every 3-5 years.
What you should do: Contact a professional immediately. A low battery doesn’t mean your system won’t work—yet—but it means you’re approaching a critical window where you could lose backup power during a power outage.
2. Sensor Failures
What it means: Individual door or window sensors stop communicating with your main panel.
Common causes:
- Loose or corroded wiring
- Water damage (common in Auckland’s rainy climate)
- Battery failure in wireless sensors
- Physical damage to the sensor
- Interference from nearby electronics
Professional repair: Technicians will test each sensor, identify the faulty unit, and replace components as needed. If it’s a wireless sensor, we’ll typically replace the entire unit for reliability.
3. Panel Faults
What it means: Your main control panel displays fault codes or stops responding entirely.
Common issues:
- Power supply failure
- Faulty control board components
- Programming errors
- Overheating (especially in rooms with poor ventilation)
- Water or physical damage
Why professional help is essential: Panel repairs require diagnostic equipment and specialized knowledge. Attempting repairs yourself could cause permanent damage or create serious security vulnerabilities.
4. Siren Malfunction
What it means: Your alarm siren doesn’t sound when triggered, or sounds intermittently.
Causes:
- Loose wiring connections
- Blown siren speaker
- Faulty siren relay on the control panel
- Power supply issues
- Water intrusion
The risk: A non-functional siren defeats the primary purpose of your alarm system—alerting you and others to a security breach.
5. False Alarms
What it means: Your system triggers without any security breach.
Common culprits:
- Dust or debris on sensor lenses
- Loose wiring connections
- Programming errors
- Interference from nearby radio frequencies
- Pet movement triggering motion sensors
Professional solution: We’ll investigate the root cause, adjust settings if needed, and ensure your system is properly calibrated to prevent future false alarms.
6. Wireless Signal Loss
What it means: Your system loses communication with wireless components (sensors, keypads, etc.).
Causes:
- Dead batteries in wireless components
- Interference from WiFi, cordless phones, or microwaves
- Blockages from metal or dense materials
- Distance limitations exceeded
- Component failure
How we fix it: Technicians will test signal strength, identify interference sources, replace batteries or components, and reposition equipment if necessary.

Choosing the Right Alarm Repair Company in Auckland
1. Check Certifications and Experience
Look for companies with:
- COC (Code of Compliance) certification – required for security work in NZ
- Multi-brand expertise – can they service your specific system?
- Long operational history – we’ve been operating for 35+ years
- Technician credentials – are staff properly trained?
2. Verify They’re NZ-Owned and Local
Supporting local businesses means:
- Faster response times
- Better knowledge of Auckland-specific conditions (humidity, coastal salt air)
- Accountability to the local community
- No dealing with overseas customer service
3. Consider 24/7 Availability
Security doesn’t sleep. Garrison Alarms operates 24/7 because emergencies don’t happen during business hours. Check if your repair company offers after-hours support.
4. Ask About Warranties
Reputable repair companies:
- Guarantee their work
- Offer warranties on replaced parts

- Stand behind their repairs
5. Get Multiple Quotes
Before committing, contact 2-3 companies for quotes. Compare:
- Price vs. service quality
- Warranty terms
- Timeline for repairs
- Brand expertise

Red Flags to Avoid
Don’t use a repair company if they:
- Won’t provide a free quote
- Can’t provide references or credentials
- Pressure you into immediate repairs without explaining the problem
- Lack COC certification
- Don’t operate locally
- Offer prices significantly lower than the market (often indicates poor quality)
When to Repair vs. When to Replace
Repair If:
- Your system is less than 10 years old

- The repair cost is less than 30% of system replacement
- The overall system is otherwise in good condition
Replace If:
- Your system is 15+ years old

FAQ: Alarm Repairs in Auckland
How quickly can Garrison Alarms respond to a repair?
Our 24/7 team typically responds to repair calls within 2-4 hours during business hours, and emergency response is available outside business hours. For non-emergency repairs, we schedule appointments at your convenience.
Can I repair my alarm system myself?
While simple tasks like replacing batteries in sensors are possible, we don’t recommend it. Professional repair maintains warranties and ensures safety. Incorrect repairs can compromise your security.
What happens if my system fails during a power outage?
Your backup battery should keep the system operational. If the battery is low or faulty, the system may not function. This is why regular maintenance is critical.
Are alarm repairs covered by insurance?
Typically no. Alarm repairs are the system owner’s responsibility. However, having a functional alarm system can reduce your home insurance premiums.
How do I know if my sensor needs replacement vs. just repair?
This depends on the fault. Our technicians will diagnose the issue and recommend the most cost-effective solution.
What should I do if my alarm is beeping but won’t disarm?
Don’t ignore it. Contact a professional immediately. This usually indicates a fault code that requires expert diagnosis. See our guide: Why Is My Alarm Beeping?
Do you service alarms from other companies?
Yes! We service Paradox, Bosch, DSC, Micron, Hikvision, Risco, and Panasonic systems, regardless of who installed them.
How often should my alarm system be serviced?
At minimum, annually. More frequent servicing (2-4 times per year) is recommended for commercial systems or older residential systems.
