Can anyone offer a solution to the problem of a Friedland wireless bell-push

I have two push units at different doors, one works perfectly but the other
fails within a day of a new battery being inserted, apparently due to the
(new) battery being exhausted. Strangely the one which fails was a separate
unit in a blister pack, bought as an addition to the main unit which was
supplied with a single push.
I sent the first failing unit back under warranty (now expired), but the
replacement which I received behaves exactly the same. I think that there
must be a wiring fault in the push unit, perhaps a short circuit, but there
is only a printed circuit board to be seen inside.


Send the second one back as well. The product wasn't fit for purpose
and they haven't solved the problem with the replacement. The
warranty is irrelevant.

Is it the type with integral light, which is intended to run
from a transformer?

The main unit is a Libra D346E wireless Chime run off a transformer
(optional). The bell push which keeps on failing is a separate D260 white
sender unit with CR2032 cell.

Hi,

Is the button at the top or at the bottom?

cheers,
Pete.

CR2032 isnt a good start, the capacity of those is 0.000000000001
joules. Approximately. Does it have a light of any kind? That would
kill it. Anyway, its not fit for purpose, return it.

For the benefit of Andrew...
The bell push is a self contained wireless unit designed to operate
from a watch style 3v Lithium cell. Powering the push from a
transformer is not an option.

The battery is perfectly adequate for the purpose, these bell pushes
can run for many years on the same cell. Current draw is much less than
a watch when the push is not operated. They are often fitted with an
LED which confirms that the push has been operated. The cell life will
be similar to the shelf life of in excess of five years, depending upon
use and usually exceeds the life of the sounder batteries.

If the cell is not lasting, then consider two possibilities.

1. The rubber button has been wrongly installed, trapping the button in
in operation permanently.

2. Moisture getting inside the bell push perhaps from mounting it in a
particularly exposed location.

Some of the crap unmarked ones definitely

There are some interesting graphs that show that the (standard) CR2032
actually has a capacity of 210mAh - if the current draw is around 0.03mA
or less...
It's down to 100mAh at 0degC and a draw of 100mA, which is still
reasonable really, given its small size.

There's summat up with it, or your supply of CR2032 cells.

We've had one for about 3 years and the Tx is still on it's original
battery.

The batteries in the sounder unit seem to last about 6 months, so yes
we do occasionally get the odd visitor.
