Always connect the Octalarm to the NT1’s S box,
avoid connecting it to an S box behind a
switchboard,
because:
•
The internal S box of the switchboard will often stop working in the case of a network
failure, preventing the Octalarm from sending a telephonic warning,
•
The internal S box of a switchboard may work according to different standards than the
S box of the telephone company’s NT1, so that faultless operation cannot be
guaranteed.
