I recently had my windows replaced and removed the SHKC8 shock sensors from the old windows. How are these typically installed? They were previously screwed into the old windows but I have no idea about screwing them to the new windows. Presumably it's a fairly common thing to attach sensors...

I have a VESDA VLP-012, which has been installed for some time. It generally reads between 0.02 and 0.03. For the last couple of days it's been somewhat erratic, with the reading oscillating between 0.13 and 0.29. Around the same time, the filter came up for replacement. I've replaced the...

I've recently purchased a new PIR to replace a faulty unit on my Galaxy G-2. The sensor supports both V2GY and Alpha, as does the panel firmware. So the hopefully simple question is: should one set it to Alpha or V2GY? What are the pros/cons of each protocol?

Hi. I've recently replaced the windows in my house due to old age. The outgoing windows were Aluminum and the replacements UPVC. During the replacement I had to remove the old alarm sensors fitted by the previous owner. Upon coming to refit them, I thought it might be time to review if the...

That was it! Took the callback number out and I'm able to connect. Really grateful for your assistance, would never have guessed to do that!

I estimate the maximum pressure to be 0.1bar

Thanks for your reply. Onto the side

What they said. I'd add: buy a multimeter

New pigs too?

I'm not an expert on street lighting but my understanding is that traditionally low pressure Sodium lamps have been used due to their high efficiency. They've fallen out of favour due to Sodium producing a very narrow spectrum of light, giving that yellow effect to everything. When using lamps...

It's hard to say what a thief would think and doubtless different thieves would take different approaches. The main point of CCTV isn't really to get a video of your TV being stolen so that you can post it on FaceTube, it's mainly there for its deterrent factor. Surprisingly, I understand...

In the event of an emergency the family pet could turn it off.

Anyone have any ideas for the best way to mount a socket on the end of a length of 20mm conduit? I'm thinking SMA or N type.

Ceramic? Asbestos? Concrete?

My guess is that the 18th edition will rename the CPC to the Farnell Conductor.

I've seen quite a few freezers that operate around -80C.
