D51 Duct Housing with Base to Suit MX Detectors D51MX
Part Number: P-D51MX
The D51MX consists of a D51 duct sampling housing fitted with a 4B base wired to suit an MX analogue addressable 850P/814P or 850PH/814PH photoelectric smoke detector. When fitted with the detector the DSU is designed to sample air in air conditioning ducts and pass the air through the smoke detector. The D51MX is fitted on the outside of the duct to be sampled allowing easy access for detector servicing and replacement of the dust filters. To cater for most duct sizes, a sampling tube extension is available in 3 metre lengths. The VIGILANT E500 Mk2 Series Remote Indicators can be used for remote indication of an alarm. Use with MX1, MX4428, 4100ESi.
