Dialler Setup
The alarm panel dialler must be set to ‘ring’ the LX20 module, which is either
pre-configured at evacomTM to dial your preferred monitoring station, or it is
the number you have programmed yourself*, whenever a signal is received
from the panel.
*Requires special software and cable, available from evacomTM.
NOTE: ANY number can be used. The alarm dialler only needs to know the
number programmed into the board, which could be 1234567 or 7777777
Single Communication Path Installations
If the LX20 is the only form of communication with the Monitoring Station, set
the alarm panel to dial the LX20 transmitter. Nothing more is required.
Multiple Communication Paths
The LX20 transmitter is best treated as a ‘phone line’. If the alarm dialler can
be programmed for more than one number, set the LX20 number as one and
the alternative communication path as a separate number.
Whichever is set as PRIMARY will be dialled first, and if no connection is
made, the SECONDARY number will be dialled.
Installation with PSTN (landline)
When retaining a PSTN line for the alarm panel, the LX20 module is installed
BETWEEN the alarm panel and the PSTN line (in serial – see diagram).
Whether the LX20 module is the PRIMARY or the BACKUP signal path for the
alarm panel, two numbers must be set up in the alarm panel dialler.
The first number is PRIMARY, the second number is SECONDARY, or Backup.
The order that you set the numbers in the alarm panel dialler depends upon
whether the LX20 is Primary or Backup.
