Solo 330-001 Smoke Alarm Tester | Marine-Grade Aerosol Dispenser

Solo 330-001 Smoke Aerosol Dispenser

The Solo 330-001 is a custom aerosol dispenser that is used to test the point-type smoke detectors in a ship’s Fire Detection and Alarm System (FDAS). This equipment lets a controlled amount of test gas get to the detecting chamber, which turns on the photoelectric or ionization sensor without getting dirt on the internal optics. This is not the same as ways to bypass manually. It is the main physical interface for testing loops that are built into marine-certified control panels like the Honeywell Notifier, Consilium Salwico, and Autronica AutroSafe systems.

Equipment must be able to handle high-salinity humidity and constant engine-room harmonics for maritime operations to be safe. The Solo 330-001 has a diaphragm mechanism that works even when there are low-frequency vibrations (5Hz to 50Hz).

Maintenance

In high-volume inspection environments, the Solo 330-001 maintains its seal integrity due to the non-perishing silicone gasket lining the cup rim. Unlike cheaper alternatives, the 330 model utilizes a patented “Aerosol Conservation” swing mechanism. This ensures that a single 1-second burst is trapped within the cup, saturating the detector sensing chamber without wasting expensive gas or leaving oily residues on the ceiling tiles.

Our Technician Tip: Always inspect the internal spring tensioner quarterly. If you’re working in sub-zero environments (like cold storage warehouses), the aerosol pressure drops; pre-warming the canister in a vehicle cabin ensures the Solo 330 delivers a consistent particle density for a swift “Pass” result on the fire panel.

Key Features

• Universal Design: Works with most modern marine smoke detectors that are no wider than 100mm.
• Aerosol Conservation: The sealed chamber design keeps gas from leaking out, which lowers the cost of supplies per trip.
• UL/ULC Listed: Meets international standards for fire safety for functional testing.
• Non-Conductive Material: Safe to use around live electrical cabinets that ETO takes care of.
• No tools are needed to connect it; it snaps right onto Solo telescopic access poles for high-deckhead reach.

Pro-Engineer Tip:

A common hidden failure observed on deep-sea vessels is plasticizer migration or fretting at the seal interface. In high-vibration zones, the seal between the dispenser and the detector can develop micro-gaps. If the ETO notices a Sensor Fault on the bridge panel during testing rather than a Fire signal, it is often due to an insufficient seal allowing the aerosol to bypass the chamber. Ensure the cup’s silicone rim is supple; if it hardens due to UV exposure or oil mist, it will fail to create the vacuum necessary for a valid functional test.

Applications

• Functional testing of smoke detectors in accommodation decks and galleys.
• Routine SOLAS compliance inspections for cargo holds.
• Verification of fire suppression release triggers in machinery spaces.
• Maintenance of smoke detection loops in high-voltage switchboard rooms.
