    Update: the strike’s supply comes from a camera doorbell, which can be activated using a fob, mobile phone or the video monitor in the house. Supply to the doorbell comes from the video monitor, which gets its supply from a 24v DC transformer plugged into wall. Supply to the doorbell is 24v DC...

    I replaced the lock, which has a longer throw than the old strike can manage. Attaching a pic, but no, can’t see + or - on the strike. Yip, testing it when the release is pressed. However see update below.

    Ac or dc electric strike?

    Hi M looking to replace my door electric strike and I’m not sure if existing is ac or dc. It says 8-12v on it but when I google the model it’s available in both versions. My multi meter on ac side seems to only have a 600 or 200 setting, and it doesn’t read anything (other than a minus...

    Vaillant F75 - pump or sensor?

    I replaced the seals on a leaking magnaclean about 3 mths ago, so possibly some debris in the system. As heating working fine for last 6 hrs, during which there’s been regular demand for HW, I think it’s less likely to be pump. Had to drain system a tiny bit this pm, removing what I added this...

    Vaillant F75 - pump or sensor?

    Yes! It’s still the 831. I noticed pressure did jump up when it started working, as had to drain the system a little (an hour after adding pressure) to get it back into green zone. Altho, that doesn’t tell me if it’s the pump on last legs or sensor does it?

    Video door entry kit - cheap Amazon option

    No, looking to buy as a kit. The Tmezon link you sent looks almost perfect. However, not keen on the name plate on the camera unit - we’ve had a brass name plate on the door for years now! Found this as an option too: https://doorentrydirect.com/srs-7052wkit-01tuya-2wire-villa-kit. Pricier, and...

    Video door entry kit - cheap Amazon option

    Having thought more about it, I’m leaning towards a system that provides: - Video to monitor (don’t particularly need it connected to a phone) - ability to release door using a phone (kids often forget keys, never ever their phones!) - I’d rather not have a key pad on the external device...

It shouldn’t vibrate, or play any alarm/siren tune - just a simple buzz sound, that in most cases will be activated for...
