TESTING THE INSTALLATION

- Check all the connections have been made correctly and dip-switches have been set

and then power up the system.

- Call the apartments. Check for call to all apartments, speech in both directions and lock

release and correct operation of the SPEAK & DOOR OPEN LED’s.

- If the volume of speech needs to be adjusted, this can be done by adjusting the presets

on the rear of the amplifier at the door panel.

PANEL CARE

The door panel is manufactured from 12 Gauge 304 grade stainless steel. It is important

that the facia is cleaned on regular occasions to prevent dirt build up and tarnishing of the

metal. A general household metal polish can be used but care should be taken to follow

the grain of the metal when polishing and also avoid any polish build up around the call

button which may prevent the button from operating correctly.
