We have three dors with electromagnetic catches linked to our smoke detecto
rs. Origially they were all made by Menvier. One failed druing the building
works and the electrician replaced it with a DRW-M Wall Mounted 230v Door
Recently the Menvier one on the top floor failed. I tried to find a Menvier
one on-line but couldn't so I bought another DRM one. Installation seemed
simple live, earth and neutral. The catch on the middle floor has only one
set of wires going into it but the one I replaced had two sets (presumably
the return loop).
I replaced the top floor one as wired previously with the two sets of wires
going into the appropriate holes on the connector block.
The catch works fine and is released when the button is pressed. However, w
hen I set off the smoke detectors the catch is not released. The wires seem
to be firmly griiped by the connector block. Any suggestions - did I buy t
he wrong catch?
