Alarm Maintenance is a scheduled service of a working alarm: testing every detector, checking batteries and power, confirming signals reach the control room, and cleaning equipment before faults appear. It suits homeowners, body corporates and businesses that want fewer false alarms and a record of when the system was last checked.
- Say how many zones or detectors the system has, if you know.
- Say when it was last serviced.
- Ask for a once-off service or an annual plan.
Describe your system once and compare maintenance quotes.

How Often to Service an Alarm
- Homes: at least once a year.
- Businesses: once or twice a year, or as your insurer requires.
- Outdoor detection: more often, because dust, spiders and plant growth affect outdoor sensors.
- After storms or long power cuts: a battery and power check.
Who Needs It
- Insured properties where the policy requires a working, maintained alarm.
- Body corporates and estates with shared systems.
- Businesses that need service records.

Alarm Maintenance FAQs
Is alarm maintenance the same as a repair?
No. Maintenance is a planned check of a working system. A repair fixes a specific fault. Faults found during maintenance are usually quoted separately.
Will a service stop false alarms?
It often reduces them by cleaning detectors, replacing weak batteries and adjusting outdoor sensors. Persistent false alarms may need a detector moved or replaced.
Do I need to be home for the service?
Yes, or someone who can disarm the system and confirm test signals with the control room.
Should batteries be replaced at every service?
Only if they fail a load test or are near the end of their life. Ask the technician to record the test result.
Does my insurer need proof of maintenance?
Some policies require a working alarm and, for businesses, service records. Check your policy wording.
