Delkims problem

[Lucy Purswell]

Hi I have 4 delkims ,early one's that have the sender unit attached to under side with a wire ariel . I have not used them in a good while (2 years or more,
new batteries,so not that. bit only 1 works via receiver unit other 3 intermittent but works ok when volume is turned up, any suggestions, I believe Delkim wont repair them because they are now obsolete . I want to sell them off as I have bought newer ones they work fine as just an alarm but not wireless set up (other than the one) ,,any ideas ???

Have you checked them for any faulty soldered wire connections?
In the past I’ve had solder fail a couple of times on my older bite alarms because of faulty soldering on wiring.

You might find the problem straight away if you have a good look and wiggle inside them. Or just ask an electrician friend to look for you if you are not very confident in doing it yourself.

don't think there is a problem with wiring as they work intermittently and fine when volume is turned up or just as normal indicators ,i.e. without transmitter device. all very odd

Working intermittently is a sure sign of a faulty connection somewhere in the circuit/wiring; like a faulty soldered connection somewhere in the circuit which has become a bit loose with age and needs resoldering.

A soldering iron has fixed similar problems in a couple of my older bite alarms in the past; and it’s normally a very simple job to do; or get someone else to do for you if you don’t have a soldering iron or are a bit unsure of doing it yourself.

I'd think Keith is probably right , a dab around on any connections with a small hot soldering iron will most likely sort out any issues . You can get what they call dry joints , where the solder has quite flowed all around a connection caused by grease/ dirt impeding the solder flow . Certainly wont do any harm if you take care.

If the alarms are working properly on their own then the problem has to be with the receiver, and more than likely a bad connection. If you know someone with the same receiver then try it using theirs as a test.

Delks are ridiculously expensive so it is well worth the trouble to source a repair . . . . .

My original optoniks are 42 rear old, had them GPO speaker converted a year after buying for greater volume control and both have been fine until a fortnight ago when one stopped working.
A look inside revealed a wire had come adrift so I resoldered it and the tiny red led that causes the " peeps" when line is pulled lit up. Bingo, was my first reaction but then I found the thing would not give any audible signal,
Apologies for jumping in on this thread but the two problems are pretty similar,
Any idea what my next move could be please??
