    Veritas R8

    I'm not round there at the min, but from power on basically everything lights up at once then goes off, and then when the double beep stars occurring, only the unset and power lights are lit. They only have door contacts. No detectors.

    Veritas R8

    Hello, My neighbours have the above alarm in their rented property. It recently started nuisance alarming so they removed the fuse from the FCU until it died. On trying to repower the alarm all they are now getting is a series of double beeps, and from the manual that seems to indicate a...

    Worcester Bosch 24i rsf not sparking.

    Hello, My (very old) boiler is not firing up. Reset button is in, and holding. Fan runs. Air pressure switch changes state when fan is running. Gas valve feels like it pulls in. (I'm not totally sure about this, but something clunks and it feels like the gas valve) Then after that...

    A few flooring questions.

    Hello all. I'm wanting to lay a new floor in my front room. The current sub-floor is 22mm T&G chipboard flooring, the floor seems flat and is currently creak free so I'm loathed to pull the whole thing up. The floor I've settled on is engineer wood T&G. Right in the doorway there is a lintel...

    Makita 18v lion 4.0ah compatibility

    Sorry to jump on this. Can I assume then that the new tools are not backwards compatible with the 3.0 batteries either. My BHP451 gearbox has had it, was gonna upgrade but may as well just get another BHP451 body from eBay whilst they are still available.

    Using armour of SWA as CPC ;)

    It was corrected, it was glanded into the panel like it should have been. When I looked up the Cu equivalent of the armour, divided it by 40 and multiplied it by five I think it worked out at about 0.9mm from memory. Zs at the panel was 0.11, I realise there may have been parallel paths...

    Derating AC rated contactors for DC use

    I won't be, I'll simply be having my device e-stopped by the machines existing e-stop circuit. Even If I created my own e-stop controls, I'd still have to interface with the machines e-stop circuit as its all part of a single automatic line. All done in accordance with BS EN 60204 and BS...

    Derating AC rated contactors for DC use

    Derating AC rated contactors for DC use

    Thanks John, You are probably correct, and as I say. My gut feeling is that I'll be ok, due to the nature of the load (solenoid valves, which are unlikely to all be energised concurrently) I was just curious to see if anyone had any bad experiences with a similar situation . Ill wait...

    Derating AC rated contactors for DC use

    The contactors are forcibly guided safety contactors that are in an existing installation, I would like to use one pole from each contactor in series so that my DC supply Is e-stopped with the rest of the devices that are supplied via them. My feeling is that they wil be ok at 24V as it is...
