D51 Duct Housing with Base to Suit 130 Series Detectors (D51Z131)

The D51Z131 Duct Sampling Unit consists of a D51B duct housing fitted with a B501AUS base in readiness for fitting an analogue addressable P131 photoelectric smoke detector. The D51B is designed to sample air in air conditioning ducts and pass the air through the smoke detector. The housing is fixed on the outside of the duct to be sampled, allowing easy access for detector servicing and replacement of the dust filter. To cater for most duct sizes, a sampling tube extension is available in 3 metre lengths. Tyco E500 Mk2 Series Remote Indicators can be used for remote indication of an alarm.Part Number D51Z131
