Product details
The 5BEx 5" Universal Base is compatible with M600Ex, MX 800Ex and the 800Exn ranges of Detectors. This document describes its use with the 800Exn series of detectors. Thus, a ceiling-mounted detector comprises the specific detector type, plus a 5BEx 5" Universal Base. The range is intended for two wire operation.
The detector base is made of fire resistant FR110 ‘BAYBLEND’. The base can be used with the DHM-5B.
The base accepts an address label carrier from the detector when it is fitted to the base. The base also has four electrical contacts which align with the contacts on the detector once the latter is fitted and fully latched into position.
The raised rib is aligned with a raised rib on the detector when the detector is in the fully home position. Loop cabling is connected to base terminals L (-ve) and L1 (+ve).
A drive is provided for a remote indicator connected between loop positive and terminal R. Terminal L2 is not used.
When the detector is mounted on the base, the detector LED provides a visual indication of its status through 360 degrees. The detector may be locked in position by inserting a locking key which is part of the detector moulding. This is broken from the sprue and inserted in the locking key slot.
The detector base 5Bex has been ATEX approved for use with the series M600Ex and series 800Ex intrinsically safe detectors and is covered by type examination certificates BAS01ATEX1134X/3 and BAS01ATEX1194X/3 respectively.
