Product details
The FireClass DPK6 duct probe unit (517.025.056) is a duct smoke detector housing supplied with a 4B-C 4” continuity base, used to detect smoke travelling through ventilation ductwork.
The DPK6 duct probe unit (517.025.056) is used because smoke detectors are not typically installed directly inside ducts: the airflow only permits the detector to sample air from a small section of the duct, leading to rapid dirt accumulation. Instead, ducting is safeguarded by the use of probe units, which collect air from a cross-section of the duct and pass it through a smoke detector head.
In most cases, smoke or combustion products are likely to have traveled some distance, aging the smoke before reaching the probe unit. Therefore, it is usually recommended to fit an optical smoke detector, often a requirement of building regulations. The DPK6 duct probe units use Generation6 850PH and 830PH Multi-Sensor Smoke Detectors. DPK6 Duct Probe Units have been developed to detect smoke in ventilation ducts, offering significant benefits in terms of performance and installation.
Frequently asked questions
Why use a duct probe instead of a detector inside the duct?
Airflow only lets a detector inside a duct sample a small section of air, leading to rapid dirt accumulation. A probe unit collects air from a cross-section of the duct and passes it through a smoke detector head.
Which detector heads are used with the DPK6?
The DPK6 duct probe units use Generation6 850PH and 830PH Multi-Sensor Smoke Detectors. An optical smoke detector is usually recommended, as smoke is likely to have aged before reaching the probe.
Is a base included?
Yes, this listing includes the 4B-C 4” continuity base.
