Installation Guide

Ref No. 492 856 (ML) Version 1
The Memcom Multi Point Station (MPS) provides external emergency telephone points for the lift engineer in the shaft,
pit or machine room. This easy to install unit also allows local communication between different points of the lift
installation through an intercom channel, which is a considerable benefit during commissioning and installation of the
elevator. The system has a unit status LED which informs the installer if the station is functioning and whether the alarm
button has been pressed. The ability to adjust the volume on the station without removing the product casing, saves
time and reduces the risk of feedback.
Using a two wire connection, up to 3 MPS units can be wired in parallel or series back to the Memcom and will be
powered by the Memcom integral battery. Further additional stations can be added, but will need to be boosted by
connecting a 24V DC power supply to each additional station.
