dwdave Posted July 17, 2015 Share Posted July 17, 2015 It is beneficial for me to place a sounder on both the front and rear aspects of my install. On the front, I have a hipped roof with a gable end. Piece of cake to mount and wire. On the back, not so easy. Brick and block cavity wall leading up to the edge of the roof. Mounting isn't the problem I foresee, however wiring to it will be. How would this usually be completed. Thanks Quote 'till the next question ...

Simlec Posted July 17, 2015 Share Posted July 17, 2015 Just have one live box and one dummy box. It's your coms which should be your most important aspect otherwise it's just a system that makes a noise. Quote Link to comment Share on other sites More sharing options...
charlie6 Posted July 17, 2015 Share Posted July 17, 2015 I agree with Simlec, a dummy would probably do. but you should consider mounting the live sounder where it will generate most attention and sometimes this is at the rear of the property. If you intend using two sounders consider the output current, which could be around 4 to 5 hundred milliamps, sometimes less. This means that two sounders take 250mA and 350mA respectively for example, that's 600 milliamps which is 100 over the rated output of the panel. They may still make a noise (probably !) but it could be reduced.. and in some cases a fuse has been known to blow at the panel because of the overload. Some installers use SCB/SAB in order to reduce current draw. Quote Link to comment Share on other sites More sharing options...
dwdave Posted July 17, 2015 Author Share Posted July 17, 2015 Thank you. I haven taken that into consideration and have fitted a 2nd psu. perhaps then, as you say, the live sounder (I already have 2) should be on the rear wall but that leads me back to the first question ... how.

charlie6 Posted July 18, 2015 Share Posted July 18, 2015 When you say 'how' what is it that concerns you ? routing the cables..mounting the sounder...connections in the panel..and so on. Quote Link to comment Share on other sites More sharing options...
datadiffusion Posted July 18, 2015 Share Posted July 18, 2015 If fitted to the rear you will lose the ability for the strobe to warn on approach of a prior intrusion, worth considering.

norman Posted July 18, 2015 Share Posted July 18, 2015 I personally don't like latching strobes, a great sign the systems probably finished re arming and is now off. Quote Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
datadiffusion Posted July 18, 2015 Share Posted July 18, 2015 No I agree it's like having a keypad that displays set status, except I think the advantages outweigh on a domestic, myself.

dwdave Posted July 18, 2015 Author Share Posted July 18, 2015 Should have been more specific ... mounting not a problem, I've got loads of double sided tape and silicone. It's the cable routing that I'm trying to figure out. At a guess id say drill through the brick at a 45° and then push the cable rods through and hope they pop out in the loft, then feed the cable through. Any advances on that? I'm going for 2 live sounders on the sheer principle that I've already got them both. It is bells only, but I'm hoping to build something that alerts keyholders. Quote 'till the next question ...

datadiffusion Posted July 18, 2015 Share Posted July 18, 2015 If a more modern property you might find the top of the cavity is covered with cement or plastic making fishing wires a whole lot more fun Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands  Link to comment Share on other sites More sharing options...

charlie6 Posted July 18, 2015 Share Posted July 18, 2015 Good point Datafussion, It's always worth an hour or so for a diyer to take a good look at the entire project, including the loft, before running a single cable.. it pays off in the long run. DWdave may well have a strobe on each box. I can sympathise with both sides of the argument as far as a latching strobe is concerned, However, I must come down on the side of 'latching' for this one. Can someone tell me why we are using double sided tape and silicon ? Quote Link to comment Share on other sites More sharing options...

dwdave Posted July 18, 2015 Author Share Posted July 18, 2015 Good point Charlie. I have cable trays and access routes for most of the cabling. Didnt really consider the sounder wiring as its being left until the system is built and soaked before I plug in any external nuisances . external sounders have been mounted ands have some batteries powering the comfort leds at the moment. Pedders - I'm running low on silicone but I've got some Pritt Stick. I'm sure that'll be the same. Thanks for the tip on knots. If that fails I might try out those wall plug things!!

charlie6 Posted July 18, 2015 Share Posted July 18, 2015 I can see the need for both items to be kept in the van for emergencies of some sort, but for the life of me Mr Happy, I can't see what they have to do with mounting a bellbox. ??? Seal the holes possibly ??? Must have missed a post somewhere. Quote Link to comment Share on other sites More sharing options...
dwdave Posted July 18, 2015 Author Share Posted July 18, 2015 To allay your fears, the boxes are mounted with plugs and screws and perhaps only the cable hole will get a dab of silicone. no sticky tape or pritt stick here. But I suppose some mothers do have em. They are out there. Just not here Quote 'till the next question ... Link to comment Share on other sites More sharing options...
charlie6 Posted July 18, 2015 Share Posted July 18, 2015 You're doing well DW, no offence meant, I just couldn't understand what the double sided tape was for. I don't know what sounders you are using but, sometimes that silicone tube comes in handy to close up any obvious (and not so obvious) holes or potential rainwater entry points.. but only do this after you have finshed sorting the sounders. It may not be needed but there are still housings on the market with IP's of around 50 or less, I have one just fished from an old install, but not that old. (Always open to comment).
