If the Octalarm is connected to a fully wired RJ-11 main connection by the telephone company,
without a connecting plug, it may cause a short-circuit in the telephone network, owing to the A-A’
and B-B’ reconnection when not active. If so, set up an additional RJ-11 connection box with only
the two centre pins connected, or else use a 2-core connection cable rather than the standard 4-
core model supplied.

Avoid connecting the Octalarm behind a telephone switchboard. In the case of a network failure,
the connections of telephone switchboards often stop working. This will prevent the Octalarm from
sending a telephone alarm!
If the Octalarm has to be connected together with a telephone switchboard, do so according to the
following diagram:
