A new alarm, an older panel that needs upgrading or a system that keeps sounding? AB Electrical installs and repairs alarms, checking sensors, wiring, controls and backup power for the way you use the property.

AB Electrical installs new alarms and works on existing panels, sensors, wiring and backup power. For a new system, we consider entry points, occupied areas and how you want to arm and use it.

False triggers or a panel fault do not automatically mean replacing the whole system. We investigate the cause and check the condition and compatibility of existing parts before recommending a repair or upgrade.
The panel, sensors, communications and backup power work together. For an upgrade, adding new features may require more than changing the keypad.
For a fault enquiry, describe the panel message and when it appears without opening the equipment. Keep alarm codes, passwords and details of security vulnerabilities out of the enquiry form.
You deal with the same electrician throughout your electrical work. If a fault is caused by our installation or repair workmanship, we put it right at no extra charge.
Panel, sensor and cable condition checked before deciding what can be retained in an upgrade.
Sensor position, settings, wiring and backup power considered when diagnosing repeated triggers.
Installed zones and backup power checked as part of the agreed work, without assuming every fault needs a new panel.
A walkthrough of arming, disarming and fault indications, with any separate monitoring arrangements made clear.
A fault investigation starts with the symptoms; a new installation starts with the layout. In either case, you should understand the agreed work and how to operate the system afterwards.
Review entry points, existing equipment and the symptoms or changes needed.
Agree compatible equipment, cable access and any monitoring-provider requirements, with a written quote for planned work.
Complete the agreed panel, sensor, cable or battery work and configure the supported functions.
Check the installed zones and backup power. Demonstrate arming, disarming and what the fault indications mean.
These indicative ranges are for early budgeting, not an AB Electrical price schedule. The panel, sensors, existing wiring and requested features determine the work. A written quote confirms the planned installation or repair; any monitoring agreement and ongoing charges are separate.

|---|---|
| New 4-zone residential alarm install | $1,200 – $2,400 |

All figures are indicative. Planned work is quoted in writing before it starts. For urgent work, call to discuss the fault and likely costs.

Check the contracting entity, worker credentials, relevant specialist authorisations and insurance, then clarify the proposed electrical work.
