No nos for running 8 core alarm cable around the house

[Mr_T25]

As part of a home renovation, I am running 8 core alarm cable around the house myself including to certain external walls to cater for external PIRs for an eventual Texecom alarm (to be wired up by a professional), before we plasterboard up.

I am doing this together with my building contractor (he drills all the holes and helps pull some of the cables through) in a star wiring method, to a central A/V room in the house.

I have avoided running the cable parallel to mains electrical cable, but can I pls confirm with some of you professionals here, the following in regards to avoiding interference with the alarm and false triggers etc:

1. Crossing a mains cable here or there to get across the house to the A/V room will not be a major issue
2. Running the alarm cable ALONG SIDE Cat 6, speaker cable, Coax cables or bell wire cable is ok?
3. In rare situation where we are limited by space or due to the cable run, an alarm cable might run along side a mains cable for a few meters and then split away from it when possible
4. Alarm cable run loosely with slack is ok and in some situations where the alarm cable is run more tightly (not the best method I know) is still ok if no pull pressure is being applied to it?

Thanks.

Ideally would be better to run screened 8 core for the ultimate protection but standard 8 core should be ok.

Crossing mains is ok, problems will only occur if running side by side on long distances.

LV cables like Cat6 or speaker cable are ok, but any cabling could pick up interference and transfer it to other cables but would be unlikely to cause any problems with alarm.

Cables are best to be slightly slack, not too tight as could break the cores over time.

Sounds like your doing it right.

Hi

I ended up using CQR professional cable. It's not shielded cable but it is more expensive than the standard shielded cable.

Thx.

Yeah CQR cable is good.

you could always get a filter https://www.securitywarehouse.co.uk/catalog/act-1313-ac-spike-filter-for-intruder-alarms-p-443.html if you get any induced ac.

I don't think you'll have any problems because you have actually thought it through and taking everything into account and CQR cable is a dam good place to start.

I picked up enough tips here from you and others...thx

Just remember where you've run them!!

Got them coming out of the corners of the plaster board so it shouldn't be that difficult!
