When Your AJAX System Needs
Professional Attention
Common issues explained simply — so you know exactly when to call us and why these problems happen in the first place.
Devices Going Offline
Your AJAX hub suddenly loses contact with detectors, keypads, or ReX extenders — leaving zones unprotected without warning.
- Hub status shows “Device Lost” in the AJAX app
- Specific zones are greyed out or unresponsive
- Alerts triggered when no one is home
- System won’t arm with offline device warnings
False Alarms
Alarms firing without any actual intrusion — frustrating, disruptive, and potentially triggering costly monitoring call-outs.
- Alarm sounds when no motion is present
- Pet or environmental triggers causing nuisance alerts
- Zones activating randomly during the night
- Motion detectors not correctly calibrated for the space
Battery Warnings
AJAX devices run on proprietary batteries not available at everyday stores — low battery warnings need expert handling before devices go dark.
- Persistent low battery alerts in the AJAX app
- Devices cycling offline after brief activity
- Battery life draining far faster than expected
- Multiple devices flagging low power simultaneously
App Connection Problems
Losing the ability to arm, view, or receive alerts remotely — often caused by network changes, firmware mismatches, or account configuration errors.
- AJAX app shows hub as offline despite power being on
- Push notifications not arriving on your phone
- Unable to arm or disarm remotely via the app
- Hub requiring reconfiguration after internet or router change
Recognise Any of These Issues?
Our Melbourne AJAX specialists diagnose and fix these problems fast — usually on the same day.
Certified AJAX System
Diagnostics
We don’t guess — we use AJAX’s own professional tools and methodologies to run a precise, structured assessment of every component in your system before touching a single setting.
- ✓ Full system report generated before any repair
- ✓ Every device individually tested and logged
- ✓ Results explained clearly — no jargon
- ✓ Written recommendations provided after each visit
Signal Strength Checks
We map the radio frequency (JEWELLER/FIBRA) signal level between every detector and the hub, identifying weak links before they cause dropouts or missed alarms.
Wireless CoverageDevice Health Reports
Using AJAX PRO Desktop, we pull detailed health data on every paired device — tamper status, connection quality, interference level, and battery voltage.
Hardware AuditFirmware Status Review
Outdated firmware is a common cause of connectivity issues and app errors. We verify all hub and device firmware versions and apply official AJAX updates where needed.
Software HealthInterference Detection
Wi-Fi networks, neighbouring systems, and physical barriers can disrupt AJAX’s Jeweller protocol. We scan for interference sources and reposition or reconfigure to resolve them.
RF EnvironmentCorrect Battery Types
Each AJAX device uses a specific cell chemistry — CR123A, CR2032, or built-in LiSOCl₂ packs. Substituting generic equivalents causes voltage drops, erratic reporting, and accelerated drain.
- ✓Genuine manufacturer-spec cells only
- ✓Device-specific battery confirmed before swap
- ✓Post-replacement health verification in AJAX app
- ✓Bulk replacement available for multi-device sites
Power Consumption Checks
Unusually fast drain often points to a configuration issue — too-frequent polling intervals, failed tamper loops, or a device operating outside its rated temperature range.
- ✓Polling interval audit across all devices
- ✓Tamper circuit and loop integrity test
- ✓Environmental factor assessment (heat, cold)
- ✓Configuration optimised for maximum longevity
Preventing Repeat Alerts
Recurring low-battery notifications after a recent replacement signal a deeper issue — poor contact, incorrect voltage, or a fault in the device’s power management circuit.
- ✓Contact spring and terminal inspection
- ✓Voltage under load measured with calibrated tools
- ✓Device replaced under warranty if fault confirmed
- ✓Scheduled maintenance reminders set in AJAX PRO
Fixing Offline Devices &
Communication Issues
From a single sensor showing “Device Lost” to a hub that’s completely dropped off the network — we trace the root cause methodically and restore full communication, not just restart the system.
Hub Connection Drops
When the AJAX Hub 2 or Hub Plus loses its heartbeat to the cloud or the SIM falls offline, arming and alert delivery become unreliable.
Range Problems
Concrete walls, steel frames, and dense foliage all attenuate AJAX’s 868 MHz Jeweller signal — leading to intermittent dropouts across specific zones.
ReX Extender Optimisation
Poorly placed range extenders can create worse coverage than none at all — signal must reach both the ReX and the hub without bottlenecks.
False Alarm Reduction &
Sensor Recalibration
Every false alarm has a specific cause. We find it, fix it, and configure your system so it only alerts when it genuinely should.
Adjust Sensitivity
AJAX motion detectors (MotionCam, MotionProtect) have configurable sensitivity levels. We calibrate them precisely for your space, pet situation, and movement patterns.
- ✓PIR sensitivity zones mapped to room dimensions
- ✓Pet immunity settings verified by weight and height
- ✓Temperature compensation applied for Melbourne climate
- ✓Dual-tech confirmation enabled where appropriate
Reposition Sensors
A detector mounted 10cm in the wrong direction, aimed at a heater vent, or directly above a doorframe will generate false triggers regardless of settings. Placement is everything.
- ✓All detector angles and heights reviewed on-site
- ✓Heat sources, vents, and windows identified and avoided
- ✓Entry and exit delay zones reconfigured correctly
- ✓Walk-test run post-repositioning to confirm clean zones
Update Detection Logic
AJAX’s software layer — alarm groups, entry delays, zone types, and arming modes — is often misconfigured at installation. We rebuild the logic to match how you actually use your property.
- ✓Alarm groups and zone types reviewed and corrected
- ✓Entry/exit delays tested against real movement times
- ✓Night mode and partial arming profiles created
- ✓Alert escalation rules configured correctly per zone
❌ Before Recalibration
- Alarm triggers when cat walks past detector
- Motion zones fire during windy nights
- Entry alarm sounds before keypad is reached
- Neighbour’s device triggering your perimeter alert
- Monitoring called out 3 times for no intrusion
✅ After Recalibration
- Pet immunity correctly set — no more cat alerts
- Dual-tech mode eliminates environmental triggers
- Entry delay matched to your actual walking speed
- Zone separation prevents cross-trigger contamination
- Zero false monitoring call-outs since service visit
Firmware Updates &
System Optimisation
AJAX regularly releases firmware updates that patch security vulnerabilities, improve stability, and unlock new features. We ensure your system is always running the right version — safely and correctly.
Secure
Security vulnerabilities discovered in AJAX firmware are patched in official updates. Running outdated firmware leaves your system exposed — we keep the attack surface closed.
- CVE patches applied as soon as AJAX releases them
- Encryption and authentication protocols verified
- User account permissions audited and tightened
- Tamper detection re-enabled after any open housing events
Stable
Firmware updates also fix bugs that cause random disconnections, ghost alerts, and sync failures between hubs and devices. We test post-update stability before leaving your site.
- All devices tested after update for regression issues
- Event log reviewed for anomalies post-flash
- Device-hub re-pairing completed where required
- Hub reboot cycle monitored for clean restart
Up to Date
New firmware unlocks features like improved MotionCam photo verification, enhanced AJAX OS 3.0 logic, and better Jeweller range. You get more capability without buying new hardware.
- All hub and device firmware versions cross-checked
- New features enabled and configured post-update
- AJAX OS compatibility confirmed across all paired devices
- Client notified of new capabilities added by the update
Version Audit
Every hub and device version logged via AJAX PRO Desktop
Release Review
AJAX changelog reviewed — critical vs optional updates identified
Staged Update
Hub updated first, then devices in sequence to avoid conflicts
Post-Check
Full system test run and stability confirmed before sign-off
Repairing Outdoor AJAX Devices
Each outdoor device has unique failure modes. We service all three major outdoor components with device-specific knowledge, not generic alarm tech guesswork.
MotionProtect
Outdoor
Dual PIR outdoor detector — designed for gardens, driveways, and entry paths. Common issues involve pet false alarms, rain-soaked sensitivity, and foliage movement triggers.
- ✓Anti-masking sensor verification and cleaning
- ✓Sensitivity recalibration for outdoor environment
- ✓Housing seal inspection for moisture ingress
- ✓Angle and height repositioning for curtain zones
- ✓Pet immunity setting reviewed and re-applied
MotionCam
Outdoor
PIR detector with photo-on-alarm capability — gives visual confirmation before monitoring is notified. Camera lens contamination and SD card faults are the most common outdoor failures.
- ✓Camera lens cleaned and photo quality verified
- ✓Photo-on-alarm trigger tested across multiple zones
- ✓IR illuminator checked for night-vision clarity
- ✓CamConnect integration with monitoring verified
- ✓Firmware updated to latest MotionCam OS build
StreetSiren &
StreetSiren DoubleDeck
Outdoor siren with strobe — the most visible deterrent on your home. UV fading, speaker degradation, and tamper faults are typical after 2–3 Melbourne summers.
- ✓Siren output tested at full volume (dB verified)
- ✓Strobe LED functionality confirmed in daylight
- ✓Tamper sensor and magnetic contact inspected
- ✓Internal battery and charging circuit tested
- ✓Mounting bracket and cable entry resealed
🌏 Melbourne-Specific
Outdoor Checks
Every outdoor service includes environment-specific inspections not covered by standard tech visits.
Hub, ReX & Network Health Checks
The hub is the brain — the ReX is its reach — and the network is its lifeline. If any of these three falter, your entire AJAX system becomes unreliable. We check all three systematically.
The hub’s internal backup battery keeps your system alive during power cuts — but these batteries degrade over time and may not hold their rated capacity after 2–3 years. We test under real load conditions, not just voltage at rest.
AJAX Hub 2 supports three communication channels: Ethernet, Wi-Fi, and cellular SIM. We deliberately disconnect each one to confirm the hub correctly detects loss and switches to the next path within acceptable time.
Signal quality between hub, ReX, and devices fluctuates over time as building layouts change, new RF sources appear, and devices shift position. We run a complete signal audit and document minimum acceptable thresholds for every node.
📋 What We Leave Behind
After every hub and network health check, you receive a written summary: confirmed communication paths, battery condition rating, signal quality per device, and any recommendations for the next 12 months.
App Configuration & User Access Fixes
Help clients who are locked out, misconfigured, or confused. We resolve user permissions, notification issues, and scenes & automation so your AJAX system works exactly as intended.
User Permissions & Account Access
AJAX uses a layered access model — admin, installer (PRO), and standard users each have distinct rights. After account takeovers or staff changes, clients find themselves locked out. We rebuild the entire user hierarchy.
Notification Delivery & Push Alert Fixes
Silent alarms are dangerous. Delayed push notifications are caused by incorrect event settings, phone OS restrictions, or firmware bugs. We verify every alert path from hub event to smartphone screen.
Scenes & Automation Logic
AJAX Automation links detectors, relays, and schedules together. Misconfigured scenes create false activations or critical response gaps. We map, test, and document every automation linked to your hub.
From a locked-out admin account to a rebuilt automation suite — we walk every client through every change, on-site.
Book App & Access SupportUpgrading Old or Poorly Installed AJAX Systems
We inherit the mess, no matter who created it — DIY attempts, bargain installers, or a previous provider who cut corners — and turn it into a system you can actually trust. Read our guide on taking over an existing AJAX alarm or compare AJAX vs Paradox.
DIY Installation Mistakes
Self-installed AJAX systems often skip critical configuration steps. Devices get placed in dead spots, zones are mislabelled, and admin keys are shared carelessly — leaving properties exposed without the owner knowing.
Full DIY Remediation Visit
We conduct a complete site audit — walking every zone, testing every sensor, and restructuring the hub, ReX positions, and user accounts from scratch to professional standard.
Budget Installer Shortcuts
Cheap installers rush jobs to keep margins up. They use generic cable, ignore signal thresholds, skip tamper configuration, and leave systems in “test mode” — disabling the very alerts that keep properties safe.
Post-Install Quality Correction
We review every shortcut taken and restore the system to manufacturer-compliant configuration — enabling previously disabled alerts, verifying signal thresholds, and giving clients a proper handover.
Locked Out by a Previous Installer
When a previous security provider no longer supports a system, clients are often left holding hardware they can’t control — locked admin accounts, inaccessible PRO dashboards, and no documentation of what was installed.
Professional System Takeover
We specialize in inheriting AJAX systems from any previous installer. Using official AJAX takeover procedures, we transfer admin rights, audit every device, and bring the system fully under your control.
AJAX System Health Reports
After every service visit, Sipko Security provides a detailed written health report — so you always know the exact state of your system, what we fixed, and what to watch for next.

Compatibility & Expansion During Repairs
A repair visit doesn’t have to end where it started. We use every visit as an opportunity to extend, strengthen, and future-proof your system — at no extra call-out cost. Considering a full AJAX alarm installation in Melbourne instead? We do that too.
Adding Sensors During a Repair Visit
Most repairs already bring us on-site. That’s the perfect moment to plug coverage gaps — adding a door contact you’ve been meaning to install, or a motion detector for the garage — without paying for a separate call-out. See our full AJAX professional catalogue for compatible devices.
Improving Coverage & Signal Strength
Weak device signals or uncovered dead zones are often discovered during a repair audit. Rather than leaving them flagged-only in the report, we action them on the spot — repositioning ReX units, relocating sensors, or recommending a ReX 2 addition.
Upgrading Hubs & Communication Hardware
If you’re running an older Hub Hybrid or original Hub, our repair visit is the right time to evaluate an upgrade path. Hub 2 Plus offers triple redundancy — Ethernet, Wi-Fi, and LTE — providing a meaningfully higher level of resilience that older hardware simply can’t match. You can also upgrade from Bosch, DSC or Hills to AJAX with no wall chasing required.
Why AJAX Systems Fail (And How We Prevent It)
Understanding the root causes helps us fix them permanently — not just patch the symptom. Here are the three most common reasons AJAX systems underperform, and how Sipko addresses each one. Also see: 5 signs your alarm system is outdated.
