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 the apartment, 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.
- Program a code into the codelock and check it releases the door for the programmed
time.
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.
