Under NZS 4512, fire alarm systems require a full monthly test — covering all zones, sounders, manual call points, and panel functions. Individual smoke and heat detectors also need a sensitivity test at least every 12 months. All test results must be recorded in a log book kept on site.

Most commercial buildings with fire alarms, sprinklers, or emergency lighting are required to have a current BWoF under the Building Act 2004. The building owner must obtain an annual compliance schedule signed off by a registered IQP (Independent Qualified Person). Failure to maintain a BWoF can result in fines and insurance issues.

A faulty or frequently false-alarming system needs investigation right away. Repeated false alarms can result in FENZ (Fire and Emergency NZ) charging callout fees, and a failed system could void your insurance or put your BWoF at risk. Common causes include dirty detectors, aging equipment, or incorrect detector type for the environment — all of which we can diagnose and fix.

A conventional system groups detectors into zones — if a detector activates, you know which zone but not exactly which device. An addressable system gives every device a unique address, so the panel identifies the exact detector that triggered, making fault-finding much faster. Addressable systems are better suited to larger or more complex buildings and are now the standard for most new installations.

It depends on the size and complexity of the building. A small commercial fitout (e.g. a retail shop or small office) typically takes 1–2 days. A medium-sized building with multiple floors may take 3–5 days. We always provide a clear timeline upfront after a site visit, and we work to minimise disruption to your business during installation.

Yes. Under the Residential Tenancies Act (amended 2016), all rental properties in New Zealand must have working smoke alarms. Landlords are responsible for installing long-life photoelectric smoke alarms in specified locations. Multi-unit or larger residential buildings may also require a full fire alarm system under the NZ Building Code depending on the building's risk profile.

Emergency lighting requires two levels of testing under NZS 4218. Monthly: a short functional test (around 30 seconds) confirms each unit activates and the battery indicator is healthy. Annual: a full 90-minute discharge test that drains the battery completely to confirm it can sustain lighting for the required duration during a real evacuation. We carry out both and provide a signed test report.

We work across a wide range of panel brands common in NZ including Hochiki, Notifier, Bosch, Aritech, and Edwards. For testing and maintenance we can generally service any compliant panel. For installations we recommend brands that offer strong local support and parts availability. We'll always advise you honestly on the best option for your building.
