SDi SOLO424 Corded Heat Detector Test

When you need fast, reliable verification of heat detectors during fire-system servicing, the SDi Fire SOLO424 Corded Heat Detector Tester delivers. This professional-grade heat detector tester gives service teams the quickest activation times — especially useful when testing high-temperature detectors up to 90°C (194°F). Available in 110/120V and 220/240V versions, the corded design removes battery uncertainty and provides consistent, repeatable test cycles for maintenance, inspection and monitoring programs.

Engineered for field-work, the SOLO424’s lightweight, universal head and angled capability make it easy to use at height, on sloped ceilings or in tight access areas. Supplied with a 5m (16ft) cable and compatible with fixed-temperature, rate-of-rise and combination detectors, it’s a versatile addition to service vans and facilities teams responsible for security and fire detection surveillance.
