To be read in
conjunction with wiring diagram
Important information - Read before you start wiring.
- Use ONLY CAT 5
cable for installation of the System 1 intercom.
(Three pair individually twisted telephone cable
acceptable but not recommended) Check cable by
stripping back approximately 500mm of the sheath
to see if the pairs are twisted.
DO NOT USE any other cable e.g. data cable , alarm cable etc. as the system will not operate correctly.
- When roughing
in the cables try to keep them as far away as
possible from 240v cables to avoid 50hz induced
hum pick up. Provide a horizontal mounting
bracket on stud walls or wall box on brick walls.
- If adding
extra room stations to the System 1 Do not
install room stations back to back on the same
wall , preferably not even on same dividing wall
otherwise acoustic feedback may occur.
- Wire all room
stations back to the exchange unit location,
preferably in a central location and near a 240v
power point. Wire front door station directly
back to the exchange unit in the same type of
cable. If the front door station is on a brick
wall provide a vertical flush wall box (Clipsal
Part No 157/1).
- When fitting
off room stations carefully strip cables and if
looping twist the cables together. It is
advisable to check cabling for shorts or open
circuits prior to fitting off equipment.
- Refer to
wiring diagram for colour connections and DO NOT
CHANGE THE COLOUR CODE as the
system will not work correctly.
- After fitting
off exchange unit remove covering off double
sided tape and attach to wall.
- Connect 16v
power supply to appropriate exchange terminals.
- Test system
for correct operation and adjust pre-set pots on
exchange unit for both voice and chime volume if
necessary. System may squeal if voice volume is
turned up too high.
- When fitting off front door station in a position where it may be exposed to weather run a bead of silicone along top and back edges of plate to stop water running down behind plate.
