Ring Sensitivity
The various configurations of modern telephone lines and the multiplicity of signals that
transit along them, require major attention in the design of phone-line interfaces. The
optimized phone-line interface on-board SmartLiving control panels has been especially
designed to satisfy present day requirements. In addition to the traditional telephone
plug for land line (PSTN) connections, there are usually boards for ISDN or ADSL
connections.
If there are ADSL filters on the line, it will be necessary to connect the control panel
downstream of the filters, to the line dedicated to telephone equipment (this line is
clearly indicated on the filters).
Following are two “trouble” conditions which may be caused by ISDN or ADSL
connections, etc. , and the “actions” you must take if you encounter such problems.
•
Problem - The control panel is enabled for “Answerphone” and “Teleservice”
functions but fails to pick up incoming calls after the programmed number of rings or
picks up after more rings than programmed. Answer - Increase the value of the
“Ring Sensitivity” parameter to a suitable level.
•
Problem - The control panel is enabled for “Answerphone” and “Teleservice”
functions but picks up during “through” calls (calls that should not involve the
control panel). Answer - Decrease the value of the “Ring Sensitivity” parameter to a
suitable level.

Calibrating the touch-screen
If the touch screen of the Alien keypad does not respond to taps, you must carry out
the forced calibration process.
You can start this process by pressing and holding for 7 seconds the (
Table 13: Alien -
description of parts, X
) button which, for the Alien/G, can be reached on the PCB after
opening its casing and, for the Alien/S, can be reached through the relative hole. Once
the calibration process starts, simply follow the instructions provided by the keypad.
