Ctec fire alarm not lit up at all Discussion ThreadCtec fire alarm not lit up at all Electrical Advice

Hi, I have a ctec fire alarm, I think it's bi wire.
There are no lights apart from the one on the power supply.
I'm puzzled as it seems it just not be getting power but the call point lights up when pressed.

Should I just replace the whole panel or replace the power supply first?

Thanks

IP2X Rating on DB Discussion ThreadIP2X Rating on DB Electrical Advice

Hi
I have come across a new DB that has been installed that requires testing. The tails to the board have come in through a 40mm bush in the side of the unit. They are 25mm tails. Therefore the IP2X rating has been compromised.
The board however is in a lockable cupboard and anyone with access to it is fully trained.
Is this acceptable?
