Cabling Audio Systems
1) Cabling should be Star Configuration (Topology). ie. Each Handset cable should go back
to a junction box or central cabinet and NOT looped from one Handset to the next. This is
purely for maintenance reasons.
2) It is recommended that 1mm diameter conductors are used from the power supply to the
(+) POSITIVE and (-) NEGATIVE of the speaker unit.
3) It is recommended that 1mm (preferably 1.5mm) diameter conductors are used for the
lock circuit.
4) Standard BT telephone cable is recommended (0.4mm per conductor) for reasons of
higher quality audio reproduction and because the pairs are twisted thereby providing a
powerful defence against interference.
5) Standard alarm cable can also be used although there is a greater risk of interference.
Special care must be taken to ensure clean and neat terminations.
6) All low voltage cabling must be run totally separated from high/mains voltage cables.
Please note that far better results are achieved using thicker conductors than combinations of
thinner conductors.
Power
Power the MIHP/6 Speaker using a 12V DC power source.
Amperage draw is dependent upon consumption characteristics of the locking used, the lengths of cable runs, the number of
handsets required to switch on simultaneously etc. As a general guide, allow 1 Amp per door. If unsure, please contact Noralsy.
Standby for Audio Systems
Simply add 12V battery to 12V DC power supply.

Place Noralsy unit on a flat surface with
PCB facing skywards. View terminal blocks
from the outside looking in. Terminal No. 1
is always the first on the left of every
terminal block strip.
