LM-2 Installation Guide v1.06

The LM-2’s OUTPUT connector should be connected to the host unit’s FACILITY PORT for the Zone in which it is installed*

with screened Cat 5 cable and shielded RJ45 plugs.

Cat 5 cable

The maximum total Cat 5 cable length should not exceed 100 m. If further modules are being “linked” together (see below),

this gure applies to the overall cable run from the host unit to the “furthest” module in the chain.

IMPORTANT: Because the cables carry low-level audio, only screened Cat 5 should be used, the foil screen of the cable being

bonded to the metal screening can of the plugs. If an LM-2 is being installed in very close proximity to the host unit, it may be

possible to use ready-made screened Cat 5 “patch” cables of short length. In all other situations, shielded RJ45 plugs should be

crimped onto the installed screened Cat 5 cable using the pinout shown below.

* There is no reason why the module cannot be connected to the Facility Port of a Zone other than that in which it is installed – though this is likely to be an

unusual installation scenario.
