DOOR PHONE PERFORMANCE
Our DP3 Door Phones can operate at distances of up to 300 meters
from the Controller, providing high quality cabling such as CAT5 is used.
This product is IDEAL for RESIDENTIAL USE or COMMERCIAL USE,
where ROAD NOISE is NOT HIGH.
It is not designed for INDUSTRIAL USE where ambient noise can be
constantly high.
The volume of the audio communication on the internal phones
should be comfortably audible (a similar level to a telephone call)
providing :
·
The person at the Door Phone is talking directly towards the
Door Phone and at a distance of no more than 1 to 2 feet away
(max 500-600 mm).
·
The Door Phone is mounted at a height of about 1.5 meters (5
feet). You can mount at a lower level to allow for very young children,
but volume will suffer.
·
No plates or other material are placed over the front face of the
Door phone. Our Door Phone Cover accessory, or a properly
designed Rain Hood will not affect performance.
The volume of the audio communication at the Door Phone should
be comfortably audible, providing :
·
There is not excessive road noise or other noise near the Door
Phone. This will affect the automatic gain circuit used in this device.
·
That high quality ADSL FILTERING is fitted ahead of the DS
CONTROLLER where ADSL is used on the same line. If you do not do
so, volume in both directions will be affected. Refer to your Door
Station Controller User Guide for detailed information on the use of
ADSL with this product.
