Struggling to remove cover of faulty security light sensor

[paralucent]

This should be a simple enough job. The new sensor has a screw in the middle. Unscrew it and the front cover comes off to reveal the wires.

But in the same place on the old sensor is a narrow slot and no screw; in fact no obvious way of removing the cover.



Any ideas?

Hi,

You could have a go at using a screwdriver to rotate the slot to a vertical position.
Then see if the cover pulls away.
If it doesn't, rotate the slot to the horizontal position and try again!
If that doesn't work, it may even be a screw!

Thanks for the suggestions.

I tried sticking several different screwdrivers into the slot and turning them to 'unscrew' the cover but nothing much seemed to happen. The slot itself doesn't move.

Turn off the power, and use a large hammer to remove it from the wall.

I might have to resort to that in the end.

It is evidently some sort of anti-tamper mechanism. I have seen anti-tamper screws before, but never anti-tamper slots!

Did you put it up? Looks as if the slot is used to prise out the plug to then reveal the screw.

A bigger screwdriver and turn anticlock, looks similar to a Wiska box type screw, they often bind up, failing that if your binning it, just break off the cover.

The guy who put it up was an alarm installer by trade. That explains the weird fixing.

Thanks. Will try that tomorrow.
