TESTING
Before connecting the system to the mains,
check the mains fail
operation of the system by going off-h ook at extensions
1
and
4
and checking that exchange dial tone is heard.
Connect Esc or t to the mains.
Lif t off the handset on eac h
terminal and check that both exchange lines can be seized.
Check
that each ter minal can both make and receive exchange line and
intercom calls.
Remember that if the exc lusive line facility is
used, only extension
4
will be able to make and receive calls on
exchange line
2.
If extensions
1
and
/
or
3
are prov ided as two wire extensions
check that extension
2
is called when either of these extensions
lift their handsets.
The most common faults likely to be encountered on installation
are disconnected or reversed signalling wires, these will result
in variety of signalling faults such as no lamp signals and
failure to correctly recognise key actions.
Some f a u l t s due t o w i r i n g er r or s may not be i m mediate ly
noticeable, it is therefore important to check that there are no
short circuits or reversals in the cabling .
