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 2
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 , preferably not even on the same dividing
wall otherwise acoustic feedback may occur.
- Wire room
stations (looped) back to the control unit,
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 SHIELDED
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.
