ACCORD XPC DIY INSTALL ADVICE NEEDED

[Guest de_deej]

Hello all,

I have done a lot of reading on this site, and I have to say you are all doing a great job.

I know the first thing you are going to tell me is the Accord XPC is not a panel to be undertaking my first DIY install on. But it was the panel I had in my last house and I liked the setup very much. I decided to read about it after purchasing one (yes of eBay). So I'm stuck with it, and I'm not really in a situation to pay for someone else to install it. (Unless anyone wants to do it for a score )

This is what I've got:

Accord XPC communicator panel.

Accord XPC Keypad

3 x Aritech EV105S PIR's

2X Surface Contacts

1X Aritech AS270 internal bell.

1x //.National Installer.// Dummy Bell Box

And I have a Live //.National Installer.// Bell Box on its way.

I'm also considering buying 3 Vipers. The system that was here originally had vipers on the window and I could re-use this but they look a bit old and are a bit taccy they are Viper model 6622. Should I bin these and get new ones.

I do have the installation guide and wiring diagram for all.

I plan to wire the zones:

Zone 1: Front Door Contact.

Zone 2: Back Door Contact.

Zone 3: Kitchen PIR

Zone 4: Living Room PIR

Zone 5: Upstairs Hallway PIR

Zone 6,7,8: Possible for the Vipers.

My questions to you are:

Should I use BT cable (only joking).

No should I use 6 or 8 core Alarm Cable ?? I have looked at all of the connections and it would appear that they all only need 6 core. I am planing to run individual cables for each zone so I don't need any extra. I understand the point of having to spare cables but if I thought their was I fault I would probably run new cable anyway.

OK thats the easy question now it starts to get difficult (well for me anyway)

1. How should I wire the zones: Normally Closed, Double Balanced or End of Line ??

2. How do I wire the Tamper wires. I read this on how to do this:

Now all that should be left are the Tamper cables for each zone, take the zone 1 green wire and connect this to one of the Tamper terminals, now twist the white wire to the green wire of the next zone and terminal block it, then follow through until your left with just the white wire from the last sensor and connect that to the vacant Tamper connection. Basically your just creating a big loop that starts at the panel, goes to detector 1, back to the panel and feeding detector 2, etc, and ending back at the panel from the last zone.

BTW thanks to Service Engineer for this advice and I'm not questionning it but I need to know if this is best for my panel ?

3. My main question is how to wire the resistors, I have the wiring diagram and its not that helpful. If somebody could walk me through this I would really appreciate it. I'm sure it will depend on how I wire the zones I understand I should use the resistors.

4. Finally, I have a dog (a staffie) , but I understand the so called Pet Immune detectors are a waist of time. So I plan to part set the system omitting the living room and upstairs hallway when we are out and he is in. I figure this is the best way as he makes enough noise to put of a burglar anyway and we quite often take him out for the whole day so when no ones there the whole house will be protected. What do you think ?

I'm sure everyone has them but the wire diagrams and guides can be found here:

Your help will be greatly received and fully appreciated.

Hi de_deej.

Firstly if you are set on installing the system yourself and are not too familiar with electronic principles I would say that normally closed is the best route for you, in essence this means that you use six wires (I would strongly recommend 8 core for the spare cores that may be needed in future) for each powered device (PIR). Use the same colours if you can for ease.

Secondly, follow Service Engineers advice on wiring the tampers.

Thirdly, if you use the normally closed method you can discard the resistors....

...and finally the idea with the mut is a good one I personally would not recommend pet sensors for a trouble free install.

Have fun.

Hi Norman,

Thanks for your very quick reply.

I wouldn't say I am an expert when it comes to electronics, but I was an electrical apprentice for a year and did gain a GNVQ in Electrical Engineering before I decided it wasn't for me. I am comfortable enough to re-wire my house and have recently fitted a new Consumer Unit so if the resistors are a better option I would be willing to give them a try. Could you tell me what benefits they give.

I hear your point about the 8-core can you suggest the best place to get it from, screwfix do 6 core for under a £10 I think I will probably be ok with 100 metres but I am going to get 200 just in case.

Finally what do you thik about the Vipers, should I re-use the old ones or should I buy new ?

Thanks again,

As far is i know the Aritech AS270 is voltage driven, you could use this by programing the single output, but i would use a speaker.

Hi Jb-eye,

Thanks for your response.

Please ignore my ignorence, but what do you mean when you say "voltage driven" ?

The specifications of the siren are:

Supply: 9V-14.2V

Current Consumption: 130ma

Frequency: 104db

Connections:

1+2 = Tamper

3= +12 V---

4= -0 V Speaker

Thanks again,

The AS270 you have requires 12 volts to trip it and would normally follow the external siren.

The loudspeaker would mimic the entry tones etc (generally the noises made by the RKP)

I would buy 2 drums of cable purely for ease, as you may wish to pull more than one cable to a similar location and would negate having to 'run off' the one drum.

The resistors mean that you would only require two wires for the circuit and two for power as the control looks for the resistance on the circuit cable and reports any shorts or opens as a tamper, It is a more secure method and also makes it harder to compromise.

I would purchase some new shock sensors, and putting them on their own dedicated circuit makes it easier to fault find without wiring them to latch on activation.

Oh and I personally disagree with the purchase of 'probable' stolen goods.

Hi Norman,

Thanks again for the quick reply.

Oh and I personally disagree with the purchase of 'probable' stolen goods.

I agree and if I could have got it from anywhere else I would have done, but I looked everywhere and apart from //.National Installer.// direct I couldn't see them anywhere else.

Anyway good point about the cable, I will get 200 metres.

I think I would like to try to wire the zones with the resistors, you say I only need four wires. would this apply to the PIR also if so what happens to the tamp connections ? I presume I wire the Aux wire as normal. Leaving the 2 Zone wires. How would I wire this using the 2 resistors, I'm guessing it is the double balanced option on the wiring diagram.

Do I use connection block to conect the alarm wire to the resistor, or do I twist them together or what ?

If possible could you send me some simple instructions on how to do this.

Finnaly, as the AS270 will follow the external siren is it wired the same way and not into the LoudSpeaker Connection on the Board ?

Thanks again for everything,

Just my two penneth

We install pet dets all the time, and so long as you follow the instructions they will be trouble free.

I know others will disagree with me (and everyone is entitled to an opinion) but a staffy would definately not be seen by a Bosch 820 if you dont want to trust a lesser detector.

I agree with the above EOL is more secure but not for beginersand 8 core is a sensible choice of cable(if you intend to go in and out of detectors make sure you join cables not being used)

Not familiar with the bell or dets your using, but the XPC is not a bad panel.

Wire thus.

Hi Peter,

Thanks for your post.

I'm not to concerned with the problems that may or may not occur with pet pir's, but I read a link that suggested that they compromise the level of security because someone could cruel or a little kid could break in etc. What do you think ??

I think I am going to try with the resistors at first, if I have any problems I will go back to normally closed.

Thanks again,
