zerozero Posted April 20, 2014 Share Posted April 20, 2014 Hi all, hoping someone can clarify something here for me I have an Elite 48 and am just pre wiring the 2 bells before climbing up to mount these things. The manual (INS154-6) is slightly confusing me as it talks about grade 3 wiring but I think the example it gives for multiple bells I think is only for grade 2 wiring. it is connecting the microswitches in series. but alongside all of this it says "for grade 3 installations using multiple units the "Fault relays should be wired in series". It isn't clear if this supercedes the diagram but I think it might... So contrary to the diagram in the manual I am wondering if I need to leave the microswitch terminals alone (they come pre-connected to msw1/2) and just run both the 8-core wires back to the box, and connect: - "Bell 1 Tamper Relay 2" to "Bell 2 Tamper Relay 1" (with a terminal block back at the panel) - "Bell 1 Tamper Relay 1" to "Panel Aux/Fault 1" - "Bell 2 Tamper Relay 2" to "Panel Aux/Fault 2" Is this right? I've used what looks like the standard wire colours Red, Blue, Yellow, Black and Green (for +VE supply/-VE bell/-VE Tamper/0V/-VE Strobe). Is there any standard that I should use for the White Brown and Orange for the "Tamper Relay 1/2" and "Op?" connectors? Thanks for any help!

matthew.brough Posted April 20, 2014 Share Posted April 20, 2014 First things first. This is a DIY install and doesn't require any EN compliance, right? www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
zerozero Posted April 20, 2014 Author Share Posted April 20, 2014 I just realised that my original post said "Tamper Relay" and it should have said "Fault Relay".. sorry. I realise that I only use the Tamper Relay if I am using a zone for the Fault, which I am not planning to do unless there is a compelling reason for doing so with having multiple bells? First things first. This is a DIY install and doesn't require any EN compliance, right? It is a DIY install so doesn't require but I would like to comply with standards as much as possible.

matthew.brough Posted April 20, 2014 Share Posted April 20, 2014 In that case I'd just parallel power, bell and strobe trigger, wire 1 bell tamper as normal and wire the second bell tamper to either an aux tamper or a zone. You may have to put a bell in scb mode due to current limitations www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
zerozero Posted April 20, 2014 Author Share Posted April 20, 2014 Thanks Matthew, but wouldn't this be a Grade 2 installation only? I would like Grade 3. Link to comment Share on other sites More sharing options...
matthew.brough Posted April 20, 2014 Share Posted April 20, 2014 If you want a grade 3 install presumably you have purchased grade 3 detectors? www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
zerozero Posted April 20, 2014 Author Share Posted April 20, 2014 Yes some, but the wireless are G2 so I understand that if I have any G2 then it downgrades the whole system grade, but surely it is better to have those parts that do support G3 running at G3? The bell being external is higher risk, so I wanted this to be higher grade. Link to comment Share on other sites More sharing options...
james.wilson Posted April 20, 2014 Share Posted April 20, 2014 Doing as matt said will not make it g2 per se. Its the fault monitoring and high sec triggers you need for that. As he says use separate circuits for each one of the devices and detector, ie fault or tamp securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

The bell being external is higher risk, so I wanted this to be higher grade. I think you are missing the point of grades and risk assessment. Even with a grade 3 bell disabling it at grade 1,2 or 3 is childsplay and with no proper monitoring of the alarm even the items detected on grade 3 systems will tell no one other than the local log which if you're not home as the alarm is set might as well not even detect the extra info. Grade 2,3 or 4 a bells only res is just that. Bells only. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
zerozero Posted April 20, 2014 Author Share Posted April 20, 2014 Thanks guys, so just so I can fully understand - when the manual says "For Grade 3 installations using multiple units the fault relays should be wired in series" why are you recommending to not do that and instead to use a zone for the fault circuit on bell 2? Will wiring the fault relays not work as I would like or are there other benefits to what you suggest? It is just that if I can wire the "Fault Relay" pair in series that it would save me a precious zone. Thanks again Link to comment Share on other sites More sharing options...
