I like the idea of the nailer, think that's going to have to be a definite investment. I take it it can be used to fire nails in for the D clips as well, the pirelli's look good for fire cable, I'm thinking more along the lines of fixing alarm/Beldon/data cable.

what is everyone using for fastening cables up with to meet with the new 18th edition changes? I've just quoted a job that has to be mostly surface trunked, so steel cable ties are out. I have just found some clips that go in the trunking, D line clips they're called. Has anyone used these before, and how much of a faff are they?

Yeah, I think they have just gone belts and braces with the external sab, 2 internal sounders, better to be safe than sorry, it just threw me a bit.....I think they may even be an scb on the back too.

I have been working in the industry for several years maintaining automatic gates, access control, CCTV and intruder. I have currently undergone SSAIB certification though, and it seems there is still a lot for me to learn as I move into doing more complex alarms and police response. Be prepared for lots of questions......first one.... I noticed 2 internal sounders side by side in an office on a grade three police response alarm, is there a specific reason for this? I looked in the regs but can't really find anything.
