Guest futura Posted July 21, 2004 Posted July 21, 2004 Hello Must say thanks for all the advice I have received so far. People on the forum seem very happy to help out. It really is appreciated. Slowly but surely I am getting there. The setup I am installing has three zones. Each zone has a door switch, several PIR/Microwave Sensors , glass breaks, smoke sensors and some with window foil such as the room that has all the power tools in it. The panel is a Castle Meridian and uses an iD system to connect all the devices. I am wondering if there is a particular order I should address all the devices? Such as does entry exit have to be say 1? Entry exit I am planning to be a PIR and also door switch. Is there an industry standard protocol for addressing all the devices such as the smoke detectors, glass breaks, Pirs, foil and switches? My other question is NACOSS related. Once this install is finished my local alarm company has been booked to inspect the installation and if it is up to standard then will NACOSS certify it for me. I have been given most of the guidelines as what to do and what not to do but I have read something in the Castle Manual which I am unsure about. It states that all iD devices must! be mounted in the sensors. This is fine for the smoke detectors, fine for the PIRs, fine for the glass breaks but impossible for the Foil and also impossible with the magnetic door switches. With the switches the biscuit is mounted coming out of the switch. It looks neat but is this unacceptable for NACOSS standards? I guess a new switch can be purchased for not much but how would I then get round this problem for the window foil as there just isnt a sensor case to put a biscuit in. Any advice on this topic once again massively appreciated. Kind regards William
BUSTER Posted July 21, 2004 Posted July 21, 2004 For foil etc you need an idjb junction box. The biscuit fits into the junction box and the foil or door contact is wired conventionally back to the junction box Any comments / opinions posted are my opinion only and do not represent those of my employer or Company

Guest futura Posted July 21, 2004 Posted July 21, 2004 Hello Buster Could the iDjb be just a normal low voltage junction box? as opposed to a specific iD version? The reason I ask is because I think it will be easier for me to get a standard junction box rather than an iD one. I found buying iD biscuits was very difficult as I am not in the security trade so I am only guessing buying an iDjb will be difficult too!! If you also have any guidance on the iD address order this would be awesome! Might give the alarm company name a miss if this is okay more respect for them than anything else as they are one of the only ones who have been kind enough locally to help me out as I am on a very poor budget and I realise installing alarms yourself in some ways is frowned upon. Dont wish to cause any problems for them hope you understand. I am determined with this project and will hopefully succeed with my installation in the end. A lot of the success I am having is owed to the really helpful comments and support I have had on this forum. It has also been a very interesting learning experience for me as a lot of the people on here have clearly wired an alarm panel or two before! and being able to get help from this level of experience and knowledge is very kind.

Guest Peter James Posted July 21, 2004 Posted July 21, 2004 Hi William We normally drill a deeper than normal hole when fitting flush contacts with id chips. If your fitting surface contacts you can drill a hole behind them for the id if its a wooden door, but dont try if its upvc. With foil you can use a normal jb but you must wire double pole from the foil to the jb to comply. It doesnt really matter which order you put the zones but most do it in a order starting at the front door end up in the room furthest away. Pete
Guest futura Posted July 22, 2004 Posted July 22, 2004 Hello Pete Thanks for the reply that really does answer both questions quite nicely. I am assuming by wiring double pole from the foil to the junction box you mean two lots of wire from the foil block to the junction box. Kind of like biwiring speakers for hifi systems? It is quite difficult sometimes to describe wiring in words so I have taken a leaf from compost corner and drawn a diagram of how I think things are to be done. Compost had been drinking at the time of drawing his diagram and was in the mood for 'abstract art' so I wasnt sure if the iD- was supposed to connect to the foil but if I followed explanation from jpaul it was so i am hoping my diagram is correct but! the iD- line perhaps shouldnt connect to one side of the foil? I am unsure on this point. Perhaps both methods are okay? Door Switches,Smoke Alarm & Window Foil is the title of the discussion where the other diagram has been kindly drawn for me. I have drawn the cavity for the biscuit in the diagram (neat idea!!) and drawn up a junction box. Hope this makes sense and is correct. Just out of interest what is the difference between a standard junction box and an iDjp? Thanks for the advice. William
CompostCORNER Posted July 22, 2004 Posted July 22, 2004 Standard junction boxes are quite adequate. Do remember that the window will be often attacked with a wet cloth on cleaning day so fit the JB out of the way so it's safe from water. Door contact wise, as well as the methods mentioned, you can actually purchase what I call a heavy duty plastic door contact. It's great for all doors that require surface contacts and is about the same size as the 8 way JB's. Great for fitting biscuits in. A good idea really that looks fine and keeps the install simple for others that need to work on the system. Tony
Guest futura Posted July 22, 2004 Posted July 22, 2004 Hi Tony Many thanks for that. Once again another useful comment I will follow up. Sorry to go on about it but I was wondering if the -iD line should be conected to the foil like in my diagram or not like in your previous? Perhaps either way is okay I am unsure? The reason I ask is because on the previous post jpaul also mentioned the wiring and in his description iD- connected to one side of the foil. William
Guest Peter James Posted July 22, 2004 Posted July 22, 2004 I meant by double pole to add a tamper circuit, not just double the alarm circuit. You sould at least install a third terminal and run a circuit from th yellow wire to the terminal then back to the id chip. (using a different wire) if the cable is tampered with you will get a tamper alarm B) . Pete
