Guest ALSEC Posted June 24, 2006 Share Posted June 24, 2006 It depends on how you work as an eng, most //.National Installer.// systems i've seen (I don't work for //.National Installer.//) have additional PSU's below the panel even if there is only 10 or so circuits.. It makes sense to me as (whether it's needed or not) it just helps the system get along without causing too much stress on the panel.. It allows for future expansion locally or upgrade in signalling.. Link to comment Share on other sites More sharing options...

Brian c Posted June 24, 2006 Share Posted June 24, 2006 Sorry, missed of....1xTexecom odyessy belbox 1xSD2 Dialler and thats the lot! Want to make sure before I confront the engineer and also want to make sure ive done my homework and know a bit so the wool isnt pulled over my eyes! It shouldn't make too much of a difference, although with 14/15 zones there must be an expander there too at around 60mA aswell. Should all still be less than 1.5Amps but an extra PSU can't do any harm Like others have said though, why do you need to confront the engineer? You'll notice if the PSU is fitted or not, it doesn't sound like he's trying to rip you off....quite the opposite in fact. PS...welcome back Gaz, try not to rub anyone up the wrong way, eh? IIRC you weren't banned, you left no? If you don't know......ask. Link to comment Share on other sites More sharing options...
arfur mo Posted June 24, 2006 Share Posted June 24, 2006 hi all, come on guys, why all the big gun stuff? this fellow is asking a reasonable question from us (THE PROFESSIONALS though you would not know it ) on something he is not too sure of, next thing happens he gets pilloried as a doghnut for not nowing better, how is that helpful? as someone who get's 'sorted' for commenting without knowing all the facts on a regular basis, why not just give him some pointers on what he has said ie -: he has supplied the kit then employed a 'pro' (assumedly) to instal it all so whats wrong with that????. nothing is there? after all thats what we always advise non-pro's to do even on existing systems in the DIY section - call in a professional, which he prudently has done so why all the slingshots - are you lot fickle or what? you not leaving him with a good impression of us are you? more a bunch of up our own backsiders imo so advise on the stregnth of what we know is installed, and the panels PSU capability, it is not overstretched if based in an inner urban location. but thats no reason not to instal an addituonal psu either locally or remotely, perhaps to avoid voltage drop. it may even be thought of as a prudent step, especially if a house in the country side, it will allow more standbye batteries and better recovery after mains failures and so on. read his words, there is no suggestion of powering the cameras from the panel, he has supplied the excellent dantec psu's. but even so the TS900 supplies a stablised supply far better than any plug-in module type unit, so no silly issues with warrenty on the camera's either should have been raised we are not talking petrol versus parrafin here. so we are left with the rated output v the current drain (in the worst scenario) / stanby capacity of batteries. not that i think its a good idea, i like seperation - we don't want the intruder ripping down a camera and 'luckily' shorting out the alarm aux 12 volt rail, and killing the voice dialler do we ?. the simple professional advice (which should have been given at the outset) is to ask for an explanation from your installer as to why he feels the need for the extra psu. the cost is not much in comparrason to what you have already spent on your security, and he may just be a very careful guy - just like me . regs alan If you think education is difficult, try being stupid!!!!

Service Engineer Posted June 24, 2006 Share Posted June 24, 2006 Im not trying to catch anyone out, just want some more opnions and making sure the install is upto standard...Im sure if there isnt anything to hide the engineer wouldnt mind telling me and it gives me a better understanding as to why costs have gone up (as a result of an extra psu).Its installers like you that let the side down, im hope your not like that to your customers... Im just making sure everything is as good as it can be and meeting all standards...sorry if this annoys you... If the installer is recommending an extra PSU then buy one, and an extra backup battery.And I have to ask why if your so concerned with the system being installed to standards isn't an approved company undertaking the installation.? ........................................................

leesutton Posted June 24, 2006 Share Posted June 24, 2006 The last company i worked for always fitted the galaxy panels and the panel psu was only used to power the bell box and any comms. We would then fit smart psus dotted around the jobs for any keypads, rios and devices so we never had any problems with voltage drop and only had short runs to add new devices....... lee  Lee Sutton E-Mail: leesutton@centurianfire.co.uk Website: www.centurianfire.co.uk Phone: 0845 094 9870 CENTURIAN FIRE & SECURITY (part of centurian group limited) Link to comment Share on other sites More sharing options...

We would then fit smart psus dotted around the jobs for any keypads, rios and devices so we never had any problems with voltage drop and only had short runs to add new devicesThat's how it should be done in an ideal world. I used to roughly work on 1 psu for every 8 zones even if the panel was capable of 16 or 32 onboard. ........................................................
