only reason is that 0.75 mm is easier to get into the alarm panel. whichever you use, the ends should be ferruled.

hello here is 2 photos of the socket i was thinking about coming off of it is actually a single radial socket on its own 16A mcb so really all i would be doing is carrying on the Radial correct?

 

[camerabloke]

Correct

 

[telectrix]

agree with ^^^^^. it's just an extension to a radial.

 

[DPG]

Looks nice and easy to extend as well - surface mounted and only one cable to worry about.

yep. comeoff socket in 2.5 T/E into unswitched FCU next to alarm panel. 3A fuse in FCU.

I've never installed a security alarm so for future informations sake why do the ends need ferrullering?! Does it prevent false alarms or something?

 

[telectrix]

it's only the mains lead flex ends need ferrules. the alarm cable terminals are designed for direct entry with alarm cable ( they have cable guard plates to stop the problem of fine strand flex cables into screw terminals. ). if you have several wires for PIRs 12V supply, etc., though sometimes a good idea to put all in ferrules, then 1 or 2 might not otherwise make a bad connection.

edit.and don't fold the ends of alarm cable over.

New Q the texecom panel lets you use fire sensors so i am going to install one in most of the rooms what i would like to know is it ok to use alarm cable out should i new the red fire alarm cable but noticed the smallest is 1.5mm is that not over kill for a 12v sensor
