First Fix Recommendations.
• Always mount call points above the final bed height to avoid damage to the call points if the beds are
moved.
• IMPORTANT Ensure Infra Red call points are located in a position suitable for infra red reception and
are not obscured by curtains, doors or furniture etc. Infra Red Receiver only units are best located on the
ceiling or high on the wall. If the infra red performance is crucial to your system, always perform a site
test before installation to establish the optimum location and quantity of infra red receiver units.
• Locating Infra Red Call Points in direct sunlight may degrade their performance.
• HIGH FREQUENCY FLUORESCENT LIGHT FITTINGS must operate above 50KHz at all times
to ensure they do not interfere with infra red systems. Most lighting manufacturers are aware of this issue
and can recommend suitable light fittings.
• Locate LCD displays at typically 1600mm from the ground for ease of use.
• DO NOT locate any device directly above a radiator or other heat source as this may affect the front
panel label and operation of the unit and LCD display.
• Power Supplies must be located in accessible positions for programming and maintenance access.
• Radio RFTX transmitters must not be located within 10 metres of any Intercall power supply.
• Do not locate audio call points and Audio display units ‘back to back’ on stud or partition walls as this
will cause audio feedback as there is insufficient audio insulation between the two units to prevent this
from occurring.
• When first fix is completed ensure INTERCALL parts are stored safely and the back-boxes and any bare
wires are protected from paint, nails and plaster!.
