3 The transmitter should be fixed to an even wall surface using suitable screws fitted
through the three holes provided in the chassis plate. Hold the chassis up to the
chosen location and with the aid of a pencil mark the position of the mounting holes.
Warning: Do not use the chassis plate as a template for drilling the holes into the wall.
Hammer drills vibrating through the chassis may irreparably damage the quartz crystals on
the printed circuit boards.
4 Place the transmitter over the mounting holes and secure the unit with suitable
screws. Check that the chassis plate does not bend and that the
snag or pinch any of the internal cables.
5 Connect the antenna to the unit via the BNC connector located at the top of the
housing. If the antenna is an external antenna, or an antenna which is separate from
the transmitter unit itself, ensure that the previous criteria covered under the section
headed Siting of the Hardware, have been strictly adhered to (also see section
headed Other Antennas).
6 Connect the input cables to the zone terminals. Note: Zones 1-3 are "dry contact" (no
voltage) inputs. Applying voltage to these inputs will cause irreparable damage. Zone
4 requires either a +12V or 0V dc input.
If in doubt, check with Scope before proceeding; incorrect connection may
cause permanent damage.
7 For the SCPUHFTX unit, connect the power input lead to the + and – terminals
provided (see diagram 3). Voltage must be 12 to 14V dc max. For the mains powered
PSCPETX unit, connect the mains cable to a fused spur (5A minimum rating) located
within 1 metre of the unit.
8 Replace the cover and refit the retaining screws.
9 With power applied, the red Power LED on the front fascia of the SCPUHFTX (or on
the lower end plate of the PSCPETX) will light.
10 The system is now active and will transmit the zone number message for each of the
zones when triggered (dependent on configuration: see Mode Setting, above).
