Guest graale00 Posted May 7, 2006 Share Posted May 7, 2006 Hello everyone, was fitting a texecom text & speech dialler and the speaker cable got damaged and shorted. Thought no problems! Joined the speaker cable again, no sound whatsoever. Hmmm tried connecting to different speakers and nothing???? Dead or Not? Any ideas would be helpful.

What happens if you connect a speaker to the panel using a short piece of cable - to eliminate a faulty cable? What is the resistance across the speaker - should be 16 ohm.

Service Engineer Posted May 7, 2006 Share Posted May 7, 2006 What is the resistance across the speaker - should be 16 ohm. No it shouldn't, it should almost read a dead short... The impedance is 16 ohms not the resistance. ........................................................

Paul Giles Posted May 7, 2006 Share Posted May 7, 2006 Still reads 16ohm when you measure across it tho!!!

sparky83 Posted May 7, 2006 Share Posted May 7, 2006 If you are talking about the speaker thats on the backplate of the speech dialler then this doesnt have to be connected for the speech dialler to work - just means you cant hear your recorded message when you press listen to recorded message.

Guest graale00 Posted May 7, 2006 Share Posted May 7, 2006 Powered down, back up again and again and again, switched speaker to another 8 Ohm speaker from a different dialler, I dont even get a tone for when I press the buttons.
