How is Automist inspected, tested and maintained?

Automist is inspected, tested and maintained in accordance with the manufacturer’s Design, Installation, Operation and Maintenance Manual (DIOM).

The DIOM defines procedures for inspection, smoke-sensor testing, system testing, maintenance and recommissioning following an activation.

Does Automist check itself?

Automist includes monitoring and automated test functions designed to help identify system problems.

Once commissioned, each spray head automatically moves approximately five degrees and resets once every seven days. This confirms that the spray-head mechanism remains free to move.

The controller also monitors system functions and displays system status and detected faults.

These functions supplement, rather than replace, the inspection and maintenance required by the DIOM.

How often are the smoke sensors serviced?

The DIOM recommends removing and cleaning the sensors at least once a year, followed by testing to confirm correct operation.

How are the smoke sensors tested?

Automist includes a dedicated smoke-sensor test mode.

The system confirms that the correct paired spray heads respond and scan when each sensor is tested.

What happens after Automist operates on a real fire?

The system must be inspected and recommissioned.

The DIOM requires the spray heads and smoke sensors associated with the activated zone to be inspected for damage, tested and recommissioned.

Where can I find the full maintenance requirements?

The full inspection, testing and maintenance procedures are contained in Section 12 of the Automist DIOM.

Conventional residential sprinklers can discharge 13+ gallons per minute across a room until the water supply is manually shut off, so even a successful activation can cause significant secondary water damage. Automist targets the fire using much less water and shuts off automatically, helping reduce damage, clean up and disruption after an incident.

Possibly. While insurance discounts or “policy credits” are determined on a case-by-case basis, Automist has already been used successfully to secure coverage and lower premiums for high-value homes — especially in wildfire-prone areas and PPC 10 risk classifications where traditional coverage is increasingly difficult to obtain.

As insurers tighten underwriting criteria due to rising wildfire risk and water damage claims, automatic discounts for standard fire suppression systems are becoming less common. However, Automist stands out as an innovative loss mitigation solution — not only by reducing fire damage, but also by minimizing the risk of excessive water damage, which is a major cost concern for insurers.

Traditional fire sprinkler quotes often exclude the cost of upgrading your water supply, which is why total costs can increase significantly. While the sprinkler system itself may cost as little as $5,000–$6,000, water utilities may require a larger meter to meet the system’s flow demand, adding both upfront installation fees and possible ongoing monthly charges. Depending on the property and infrastructure, these additional costs can range from a few thousand dollars to much higher in complex cases. Automist operates at significantly lower flow than conventional sprinklers – a standard domestic meter can handle the demand without upsizing.

Yes. Automist is well-suited to modular and prefabricated home construction, and a growing number of modular builders in the US are choosing it over traditional sprinkler systems. Traditional sprinkler systems create challenges for modular builds: rigid pipe networks require inspectors to view every joint on-site, keeping ceilings and walls open until inspection, which moves finishing work off the factory floor and onto the site. This adds labor, time, and cost. Automist offers two alternative approaches that many AHJs accept: factory documentation with pressure testing on-site, or conduit installation in the factory for hose pull-throughs on-site. Both eliminate the need for open ceilings at the point of inspection.
