Hi all, could determine if I should post in this forum or the visual forum.


I installed a MPC01 controller, that connects to a BL627 amplifier, then connects to a LFL liberty lightbar. Trouble is is when I run the siren the siren sounds for about 3 seconds then restarts. When I disconnect the light bar from the communication wires the siren works fine. Is there a trick to adding a light bar with comm cables to a siren amplifier and control box?
