[QUOTE="Richard-the-Ninth, post: 468419, member: 23472"] I never said it will overload anything. The fact that you have 2 sounders makes a lot of difference. I would also guess it is the cause of your problem. I shall try and make it as easy as possible. When you install two sounders on the same panel they are NOT wired "both the same" so to wire one the same as the other will not work. If they are wired wrong, or "lashed up"they will "work" but the tampers are disabled. I am guessing yours were wired as they should be. ______________________________________________________________________________________________________________________________________ This is how it is done. You have 2 sirens Front and Back. The front siren is wired as normal The rear siren isn't wired as normal The tamper return for the front siren is now used as the negative hold off for the rear siren. (The positive hold off and ringer are normal) The tamper return for the rear is now the single tamper return. ________________________________________________________________________________________________________________________________________ You can get several problems with incompatible sirens or just cheap sirens, which can manifest them selves in various ways, the most common being that no matter how you wire it, the second siren will not stop. The other one is it works for 30 seconds, then when you test the sounders, they both activate, but then one will not stop. You have 4 choices. 1) Do away with one of the sirens 2) Change both sirens to the same make and model and cross your fingers 3) Install a relay for each sirens tamper 4) Get some one in who is an "Alarm engineer" who know how to do one of the above. (it usually ends up as option 3) [/QUOTE]
