The Testifire XTR2 uses dedicated aerosol canisters to generate smoke during detector tests. Depending on the test types you need to perform, you may also use heat cartridges and CO gas canisters, each designed specifically for the XTR2 and available as separate consumables. Keeping the right stock onboard means you can carry out compliant detector testing at any time, without delays in port.

Which consumables are compatible with the Testifire XTR2?

The Testifire XTR2 is designed to work with a specific range of branded consumables: smoke aerosol canisters, heat cartridges, and CO gas canisters. These are purpose-built for the XTR2 and ensure the tool delivers accurate, repeatable test results. Using non-branded or generic alternatives can affect test reliability and may compromise your compliance records.

The XTR2 is an all-in-one cordless detector testing tool that combines smoke and heat testing in a single unit. Because it supports combined and sequential test modes, the consumables you carry onboard depend on which detector types are installed on your vessel. A ship with only smoke and heat detectors will have different consumable needs than one that also includes CO detectors.

Always check that you are ordering consumables that match the current XTR2 model. The product range has evolved over time, and earlier Testifire consumables are not always interchangeable with XTR2-specific ones. When in doubt, verify compatibility with your supplier before ordering.

How long does a Testifire XTR2 aerosol canister last?

A single Testifire XTR2 aerosol canister typically provides enough smoke for around 50 to 100 individual detector tests, depending on the duration of each test and the test mode used. Combined test modes that run smoke and heat simultaneously may use slightly more aerosol per activation than smoke-only tests.

In practice, the number of tests you get per canister varies based on how long each activation lasts and how frequently you use the clearing mode, which helps prevent repeat alarms after testing. For vessels with large detector counts, it makes sense to carry at least two spare canisters to avoid running short mid-inspection.

A good rule of thumb: plan your consumable stock based on the total number of detectors onboard, plus a buffer for re-tests or failed activations. If your vessel undergoes regular scheduled inspections, you can forecast canister usage over the year and order accordingly.

What’s the difference between smoke, heat, and CO consumables for the XTR2?

Each consumable type triggers a different type of detector and serves a distinct testing purpose. Smoke aerosol canisters generate a simulated smoke cloud to test optical and ionisation smoke detectors. Heat cartridges produce rapid heat output to activate heat detectors, with the XTR2 capable of reaching up to 100°C. CO gas canisters release a controlled concentration of carbon monoxide to test CO detectors specifically.

These consumables are not interchangeable. A smoke canister does nothing to verify a heat detector, and a heat cartridge will not trigger a CO sensor. For vessels with a mixed detector installation, you need all three types to achieve full test coverage across your fire and gas detection system.

When planning your onboard consumable stock, map out which detector types are installed in each zone. This helps you avoid carrying excess stock of one type while running short on another. The XTR2’s support for fire and gas detection testing across multiple detector categories makes it a flexible tool, but that flexibility only pays off when you have the right consumables available for each category.

How do you store Testifire XTR2 consumables safely onboard?

Testifire XTR2 consumables should be stored in a cool, dry location away from direct sunlight and heat sources. Aerosol canisters and CO gas canisters are pressurised, which means they must be kept away from high temperatures and open flames. Follow the storage instructions printed on each canister, as these reflect the manufacturer’s safety requirements.

Onboard storage conditions matter more than many engineers realise. Engine rooms, boiler rooms, and areas near exhaust systems are not suitable storage locations. A dedicated equipment locker or a ventilated storage cabinet in a cooler part of the vessel is a better choice.

A few practical storage tips for onboard use:

• Store canisters upright to prevent valve damage
• Keep consumables in their original packaging until use
• Check expiry dates regularly and rotate stock accordingly
• Never store pressurised canisters near electrical panels or ignition sources
• Log stock levels as part of your regular maintenance records

Keeping an accurate inventory of consumable stock is also useful when reporting to classification societies or port state control inspectors, as it demonstrates that you maintain the tools needed for ongoing detector testing.

Where can you source Testifire XTR2 consumables for ships in port?

Testifire XTR2 consumables can be sourced through specialist maritime equipment suppliers. Because these are branded, purpose-built consumables, they are not always available through general industrial distributors. Working with a supplier who holds stock specifically for the maritime sector is the most reliable way to get what you need quickly, especially when a vessel is in port with limited time available.

For fleet engineers and technical superintendents, the priority is speed and certainty. A supplier who can confirm stock availability, provide the correct product for your XTR2 model, and arrange fast delivery to the port is far more valuable than one who offers a lower price but cannot guarantee delivery within your port window. Lavastica, as a maritime equipment specialist based in Rotterdam, maintains stock of fire and gas detection consumables and spare parts for fast worldwide delivery.
