FAQs

How does the ALTAIR io4 ensure compliance with UK safety regulations?

The io4 automates compliance by creating a digital, tamper-proof “paper trail” of gas encounters and calibrations in the MSA Grid. This fulfills UK employer requirements under COSHH and Management of Health and Safety at Work Regulations 1999, providing audit-ready reports that eliminate human error in manual logbooks.

Can PQS Survey Ltd provide hire, service, and repair for my ALTAIR io4 fleet?

Yes, PQS Survey Ltd supports the full lifecycle of the io4 through short or long-term hire and purchase options. Our in-house service centres handle mandatory 6-monthly calibrations, sensor replacements, and repairs, with nationwide depots available for quick turnarounds or swap-out units to ensure continuous site safety.

What is the main difference between the ALTAIR io4 and the ALTAIR 4XR?

The 4XR uses Bluetooth for local phone connectivity, while the io4 features integrated CAT-M LTE cellular connectivity. This allows the io4 to connect directly to the cloud without needing a smartphone or Wi-Fi, giving safety managers instant access to live field data from any location.

How does “Instant Device Assignment” work with the MSA id Tag?

The io4 replaces manual sign-out sheets with a “Tap-to-Assign” process. A worker taps their personalized RFID fob against the detector to assign the device to themselves, ensuring that all alarms and data points recorded in the cloud are automatically linked to the correct individual for accountability.

What is the benefit of the “MSA Grid” for a site manager?

The MSA Grid is a cloud-based dashboard that displays the live status, gas readings, location, and compliance health of every io4 unit on-site. If an alarm is triggered, managers receive instant notifications, enabling a faster and more coordinated emergency response compared to non-connected devices.

Does the io4 feature the same “Fast-Response” sensors as the 4XR?

Yes, the io4 utilizes XCell sensors that trigger alarms up to twice as fast as the industry average. These sensors are built for longevity, typically lasting over 4 years, and are supported by the same comprehensive 4-year warranty as the 4XR model.

What is the “Compliance Checkmark” on the io4?

The io4 features a “smart” on-screen checkmark and a green LED that only appears if the unit is within its calibration window and has passed a recent bump test. This compliance status is synced to the MSA Grid in real-time, automating safety record-keeping for the fleet.

How rugged is the io4 compared to the 4XR?

The io4 meets the same extreme durability standards as the 4XR, with an IP68 waterproof rating and a 7.5-metre drop-test certification onto concrete. It is specifically engineered to withstand the harshest “boots-on-the-ground” conditions found in UK construction and utility environments.

How does the io4 help with “Over-the-Air” (OTA) updates?

The io4 receives firmware updates and software improvements wirelessly via its cellular connection, much like a smartphone. This eliminates the need for physical PC connections, ensuring the fleet is always future-proof and equipped with the latest safety features automatically.

What happens if a worker triggers a “Man-Down” alarm?

If the MotionAlert sensor detects 30 seconds of immobility, the io4 sounds a local alarm and sends an Emergency Live Monitor alert to the safety manager via the MSA Grid. This notification identifies exactly who is down and provides their precise location on-site using internal GPS data.
