The LH-3000 is intended for

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.

Distance between loud hailer and intercom speaker is 2-20 m.

Twist and trim the shield.
