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 3 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 vertical wall box on
brick walls.
- Do Not
install room stations back to back on the same
wall , peferably not even on the same dividing
wall otherwise acoustic feedback may occur.
- Wire all room
stations (they can be looped - up to 3 on one
cable with a maximum of 8 room stations per
system 3 control unit) back to the control unit
location , preferably in a central location and
near a 240v power point. Wire front door station
directly back to the control unit in the same
type of cable. If the front door station is on a
brick wall provide a vertical flush box (Clipsal
Part No 157/1).
- If wiring a
music input jack use SINGLE
CORE SHEILDED MICROPHONE CABLE
- 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.
- When fitting
off control unit drill appropriate cable entry
holes in the case with a hole saw. Keep control
box at least 300mm away from plug pack and alarm
panel.
- 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.
