[QUOTE="SLIPSHOD & SLAPDASH, post: 468613, member: 16"] I certainly did not make any mention of relays to control sounders which is a commonly used method in many applications. You mentioned them for the tampers, which i have never seen and can see no need for. I also did not say dont do it just because i have not seen it done, it was an observance from over 40 years of my work, 10 of these only in intruder alarms. Ps. I have also never seen an alarm control centre like the last pic, seen a lot worse. I believe the problem is still the tampers between the 2 sounders ard not wired in series [/QUOTE]
