Discovery Marine Addressable Mounting Base
The Discovery Marine Mounting Base is 100 mm in diameter and has five connections; L1 (negative line in and line out - double terminal), L2 (positive line in and line out - double terminal), -R (remote LED negative supply - double terminal), +R (remote LED positive supply - double terminal) and EARTH (earth/ground - single terminal).
An earth connection is not required for either safety or correct operation of detectors. The ground (earth) terminal is isolated and is provided for tidy termination of grounded conductors or cable screens and to maintain earth continuity where necessary. All terminals are marked according to their function.
Bases have a wide interior diameter for ease of access to cables and terminals and there are two slots for fixing screws. Detectors fit into bases one way only, without snagging, and require clockwise rotation without push force to be plugged in.
