mk2dee Posted April 4, 2009 Posted April 4, 2009 a fused spur for a domestic alarm. just to settle a we argument at work lol, is it ok to spur off a ring main in 2.5 t&e? and what about spuring off lighting circut im 1.5 t&e? what is the proper reg for spurs for alarm? cable size? etc
Woosh Posted April 4, 2009 Posted April 4, 2009 My preference is a dedicated circuit. However a sput in 2.5mm T+E is ok Not recommending the lighting circuit idea.
mk2dee Posted April 4, 2009 Author Posted April 4, 2009 just as i thought i was alway told to spur 2.5t&e off a ring main why wouldnt you recommend coming off a lighting circut with 1.5 t&e?
Alarm Protection Posted April 4, 2009 Posted April 4, 2009 2.5 of a ring main and 1.5 of a light circuit but what happens when customer is away on holiday with the alarm set and say the light circuit trips with a blown bulb on day one two etc.....? !
james.wilson Posted April 4, 2009 Posted April 4, 2009 you leave lights on 24hr when you go away? Only way to put a new circuit in is to be part p. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
Rulland Posted April 4, 2009 Posted April 4, 2009 you leave lights on 24hr when you go away?No but some people use 'plug in' lights to simulate activity whilst away Only way to put a new circuit in is to be part p. Ehmmmmmm..................so all intruder companies etc adhere to this? But I always come off a 230v ring with a spur anyway!.....................
dpaengineer Posted April 5, 2009 Posted April 5, 2009 'Plug in' lights.......... The key is in the sentance, they are 'plug in' hence on ring so wont trip lighting ciircuit. Personally I dont see a problem with spuring off lights so long as the circuit demand allows i.e. A circuit with 11 or 12 lights on it couldn't really cope with the demnad of an alarm. 4 or 5 and your fine. Also make sure the breaker is labelled at the CU as lighting AND ALARM. Obviously other methods are better but sometimes, just sometimes, there is no option. Trade Member
