This is the answer I got from Microsoft Co-pilot regarding phasing out ionization smoke detectors:

Yes, ionization smoke detectors are increasingly being phased out in healthcare fire alarm systems due to safety, regulatory, and technological concerns.

Here’s a breakdown of why this shift is happening and what’s replacing them:

—

🔥 Why Ionization Detectors Are Being Phased Out

• Radioactive Material Concerns: Ionization detectors contain a small amount of radioactive material (typically Americium-241), which raises disposal and environmental safety issues. This has led to stricter regulations and reduced favorability in sensitive environments like hospitals

• Detection Limitations: Ionization detectors are better at detecting fast-flaming fires but are less responsive to smoldering fires, which are more common in healthcare settings. Smoldering fires can produce significant smoke before flames appear, making early detection critical

• Regulatory Shifts: Healthcare facilities are governed by strict codes such as NFPA 72 and the International Fire Code (IFC). These increasingly favor photoelectric smoke detectors or multi-criteria detectors that offer better performance across a range of fire types

🏥 What’s Replacing Ionization Detectors in Healthcare

• Photoelectric Smoke Detectors: These are more sensitive to smoldering fires and are now preferred in patient rooms, corridors, and sleeping units. They do not contain radioactive material and are easier to maintain and dispose of

• UL 268 Compliant Detectors: New standards require detectors to meet UL 268, which includes enhanced testing for nuisance alarms and better fire detection performance. Many healthcare systems are upgrading to these newer models

• Integrated Systems: Hospitals are adopting smart fire alarm systems that integrate smoke detection with nurse call stations, visual indicators, and automatic door closers to streamline emergency response

⚠️ What This Means for Facility Managers

• Compliance Updates: If you’re managing a healthcare facility, review your fire alarm system for compliance with the latest NFPA 72 and UL 268 standards.

• Replacement Planning: Begin budgeting and planning for replacement of ionization detectors with photoelectric or multi-criteria models.

• Disposal Protocols: Ensure proper disposal of ionization detectors due to their radioactive components.
