Piezo transformer heat

[calumr135]

Hi all, i have replaced an old bellbox with a klaxon flashguard xtra, the issue is the alarm cable is at the other end of the sounder near the piezos and the cable entry is at the other end and i do not have much slack to move it away from the transformer area. The cable is behind the backplate in line with the piezo transformer, my concern is the heat from transformer when the piezos are sounding may overheat the alarm cable behind the unit, the backplate is black so that does not help much.

Is this a cause for concern or am i worrying over nothing? How hot do piezo driver transformers get?
Thanks

No

Okay so its nothing to worry about and the cable will be fine?
Thanks

Can you confirm the alarm cable will be fine?
Although not relevant but just interested what voltages do these piezos run at when sounding? Are they high enough to cause a shock, or is it just the strobe circuit that is dangerous on bellboxes?

Maximum valtage on the Piezo sounders in your bell box is probably 24 volts. List of various common Piezo sounders and their operating voltages HERE

Voltage on the strobe could 1000 volts ( hence the protective clear cover )

If there was enough heat to damage the cable then the plastic back plate would have to be hot enough to melt. I am sure the manufacturers will have thought of that and designed it so that the back plate does not melt.

Thank you for the information, Its sounds like there is nothing to worry about. At least there is some good people on this forum.

Its not sly, anyone viewing your profile will see it i'm sure, but very well if you want it on here, i was saying if you cannot be bothered to help then get lost and leave it someone who will and stop wasting everyone's time with your stupid unhelpful comments.
