[QUOTE="Richard-the-Ninth, post: 394364, member: 23472"] Why? please can you explain to me WHY? Also, if you do that you will not know which one went off, it really is pointless and a waste of time, oh not to mention annoying for the neighbours....allow me to expand on that. All external sounders must stop after 15 minutes, to make sure of this external sounders have an inbuilt 15 minute cut off timer. Sounds good. If an auxiliary zone is activated the external sounders are pulsed, to differentiate between fire and intruder. Sounds good. As its auxiliary it is meant to save lives, so it does not stop after 15 minutes. Since it pulses the output the external siren does not see that as 15 minutes (which is true, it is not 15 minutes of continual operation) so the external siren can and does pulse for hours / days or until some one hits it with a sledge hammer. I will say its not all panels that will do this but most of them do, and as said you should also install additional internal sounders, which in turn means an additional power supply and battery to cope with demand, its just not worth the money, effort and hassle [/QUOTE]
