Fire Systems

Fire protection systems in New Zealand can be divided into active or passive, but they also differ in the type of suppression used.

Active systems include devices that require action, such as sprinklers, alarms, and fire extinguishers. These devices can be activated automatically, like sprinklers and sirens, or manually, in the case of pull stations and extinguishers. Manually-activated fire protection systems are preferred when people know how they should proceed. A fire monitoring system receives signals from alarms and sends them to a central point for response. Across a building, a fire control system can coordinate alarms with suppression equipment.

On the other hand, passive systems are designed to passively contain fire, preventing it from spreading further. Commonly-used devices include fire-resistant dampers, doors, and drywall. Using fire-rated walls, doors and other barriers, a firewall system can limit fire and smoke movement between areas.

These are the most common suppression devices for residential and commercial fire systems in New Zealand. These are sprinklers attached to an active water supply. Once the sprinklers engage, the water will be automatically released. A fire pump system supplies the pressure and flow required by sprinkler or hydrant equipment where the available water supply is insufficient.

Dry pipe systems combine sprinklers and pressurised gas, such as nitrogen. It’s used in situations where pipes can freeze, so that water can flow freely into the system after it’s activated.

Chemical foam is usually used when traditional water sprinklers can’t be used, such as grease fires. It’s a smaller system specially designed for industrial kitchens, but it can also be installed at home.

These fire protection systems are the preferred method to secure high-end electronics and server rooms. Carbon dioxide is kept as a pressurised liquid inside the piping using liquid nitrogen and it's released as a gas when the system is activated.

These use a water-based foam to quickly suppress fires in situations where flammable liquids are present, such as oil containers, warehouses, and others.

The main advantage of high-quality systems in New Zealand is that they decrease the need for human intervention if a fire occurs, which can save lives. Fire protection systems are a more cost-effective solution compared to hydrants and hoses, as they use less water. They help reduce the potential damage, while also resulting in less heat and smoke, making it easier to guide people to emergency exits.

The first thing to consider when choosing a system in New Zealand is your needs. Are you looking to protect a residential property, a commercial building, or an industrial warehouse? The most suitable fire protection systems will depend on your answer to this question. When it comes to installations in older buildings, it’s crucial to account for the structural integrity, as the added weight can negatively impact the property. Expert advice is also very important with any such system and must come from those who are well-versed in the laws and regulations in New Zealand.
