spur and light

[horace1]

I am wanting to put a fused spur from a double socket, this is to run an alarm system, the part p all sounds confusing anybody help please,
also if i want to put up an outside light 500watt with sensor, can i put into a plug then place in socket that way would this get me around part p???

The alarm should be run from its own MCB in the consumer unit. And should NOT be on the side protected by the RCCB.

Reason.

While you are on holiday the RCCB is tripped and the batteries in the alarm system enventually run down. Your house then unprotected.

Bernard, I think you are presuming Horace has a split load consumer unit, if so you are quite correct but it is not possible otherwise.I would not recommend plugging light into a socket on a permanent basis but at the end of the day it is your house.

Yes I was presuming a split load consumer unit.

Using a larger capacity battery (external to the alarm unit) is the other way to cope with prolonged loss of mains to the unit.

that is assuming the panel can charge it.

most panels can't

Keep the internal battery. Use a 1 Amp diode ( 1N4001 from Maplins ) to prevent the alarm charger charging the external battery. If there is a long power cut and the internal battery gets down to the voltage of the external battery less the diode voltage drop the diode starts to conduct and the external battery takes over. Most alarms will work at 11 volts so a nominal 12 volt external ( actually 13 volt) less 0.7 ( 12.3 ) will be adequate to feed the alarm. A Schottky diode has a lower voltage drop.

The external can be charged with its own trickle / float charger.

Why so arsey or did you write it all the part p yourself if you did i apologise if you didnt "ye knows too much" for your own good

you said that you wanted to hear a professionals opinion about part p, that is what you got.
You being a newbie do not realise how may times people ask the same questions, that is why i suggested you look in the wiki

as for why cant you plug your alarm in, think about it.

clue. any plug can be unplugged intentionaly or unintentionaly

It was the light plugged into the socket not the alarm!
