Fire-Lite SD365T-IV addressable photoelectric smoke detector with thermal sensor, ivory finish.

Compliance

• UL 268 listed
• UL 521 listed
• NFPA 72 compatible

Key features

• Combined photoelectric and thermal sensing for dual-technology detection in a single head
• Rated for air velocity 0 to 4000 ft./min. in duct applications
• Alarm current 2 mA at 24 VDC; operating voltage 15 to 32 VDC
• Ivory finish (-IV) for visual coordination in commercial environments

The SD365T-IV combines photoelectric smoke sensing and a fixed-temperature thermal element in a single addressable detector head. This dual-technology design provides a secondary confirmation layer — the detector reports an alarm only when both the smoke chamber and thermal element indicate fire conditions, reducing false-positive activations. The T suffix denotes the integral thermal sensor, while the -IV suffix indicates ivory finish. It is compatible with Fire-Lite addressable SLC panels using LiteSpeed protocol, and both UL 268 (smoke) and UL 521 (heat) listings apply.

Verify panel/device family compatibility before ordering.
