To Solder Or Not

[Guest heliart]

Is it good practice to solder wires when connecting wires into a terminal on a panel.

Few examples,

1. if putting 1 wire into a zone, should you leave wire as is, or solder up. I'm thinking to leave as is to get a better mechanical attach.

2. Putting 2 or 3 wires into a +12v terminal on a panel. Solder together, or use one wire off to a terminal block, then double up there.

Thanks guys, you people are really helping me out.

I solder all my resisters on site, and depending on the complexity of the site i sometimes get carried away and Tin the Ends of all wires, but i say it isnt needed.

I concur

Putting 2 or 3 wires into the terminal is no big deal, but any more than that then do as you said and have one core out of the terminal into a terminal block, and then twist all the cables together and fit there.

Soldering will be a pain especially if you have made a mistake with the cables and have to add/remove some

How about when joining a pair together inside a PIR or similar when looping to another detector (meaning seperate zones, just sharing a cable)?

What i usually do if i need to carry on to another detector, is break In the the cable by just leaving a loop in the first detector and then breaking the sleaving cutting the ones you want leaving the ones to carry through, but if its an addon, i would be able to do this, i always solder and either heat shrink (If i have any) or tape up.

I never solder / tin panel connections in case modifications need to be done at some point in the future.

Joints, for example in a pir to add extra ccts are either soldered or crimped with 99a crimps.

Panel and other connections are never tinned or soldered, All other joints are always soldered and heat shrink-ed, always have done always will do.

sometimes you need to tell some installers to get their driver out and tighten the terminal but your right leave as.....with the +v term if your struggling to get them in fit two single cables(allowing for 0v) to a chock block...

There's a bit in 50131-7 about joints and soldering..

ix: use of adequate jointing methods e.g. junction boxes

(soldering or crimping only to be used when use of a junction box is impractical)

I would'nt bother tinning the ends of cables personally and I've never seen it done but I suppose it could be useful to do it on the Hold Off supply to the bell, so when it's removed on service, you can get it back in the terminal without the ends fraying and potentially shorting.

Soldered and heat shrink joins only for me if its in a passive/DT. I have actually seen choc bloc (!) used in a couple of detectors to join cables etc, where the installer has had to trim the plastic insulation around the screw terminals to get it to fit behind the PCB.
