  1. Sounds like a faulty panel or damaged wiring Have you done any building work or drilling?
  2. Came across this very old Bentley panel last week that hadn't been serviced since 87 apparently and still in good working order. Anyone had anything older that's still going strong or maybe something you installed many moons ago?
  3. Speakers are use to amplify any sounds from the control panel or keypad such as entry exit tones & chimes where a sounder will just make a noise when power is applied like a external bell box
