1. INSTALLATION

Power connection
The LH-3000 is intended for
use with a 13.6 VDC power
supply. Connect the power
cable (local supply) to the
terminals labeled “13.6V”.
Use cable type DPYC-1.5 or
equivalent. Fabricate the
cable as shown below. For
longer runs the wire size of
leads should be increased
accordingly to minimize line
losses. The wire connected to the positive (+) terminal must be connected to the positive
terminal on the DC power source, and the wire connected to the negative terminal (-) must
be connected to the negative terminal on the DC power source. If the power leads are
reversed the fuse (inside the Loud Hailer) will blow.
Intercom speaker (option)
Up to four intercom speakers may be connected to the intercom speaker terminals labeled
CAL1-CAL4. Connect each speaker to the terminal block according to desired intercom
speaker selection. The cable end is prefabricated. However, to meet EMC requirements the
length of the cable must be less than 1 m. If the distance between the Loud Hailer and
intercom speaker is greater than 2 m (max. 20 m), use a junction box (local supply). For the
connection to the junction box use cable type CO-SPEVV-SB-C 0.2X2P (option) and
fabricate it as below. In this case, the length of the cable between the junction box and an
intercom speaker must no be more than 1 m regardless of whether the equipment must
meet EMC requirements or not.

Distance between loud hailer and intercom speaker is less than 2 m.
