Hi Everyone, I have an 1832 DSC, I have 3 sirens ... the one that usually comes inside, and two MP-200 exteriors however, I think they sound a little low, can that be possible? Is it possible that the siren when connected to the battery sounds low? Shouldn't it be connected to the panel? Notice that I have many elements in the alarm. Many sensors both indoor and outdoor. Thank you.

which sound under the exterior? think that if you are inside the house and sound the sirens you will hear the inner siren more than the outside one, because it has it closer and echoes at home. if they connect to the battery, it is for them to have more current, since the battery is added plus the one given by the pnel itself for charging the battery. To test the sirens you can shoot them directly with a fountain and go outside to hear them.
