Veritas R8 Plus no power to PIR Sensors

Recommended Posts

Posted (edited)

Hope someone can help me. We had a new conservatory and I disabled and removed the PIR sensor in there. Today the electricians came and wired up the lights etc in the conservatory and they turned the power off.

This evening I reconnected a new PIR Sensor in the conservatory went to do a walk test and none of my PIR sensors were working. Checked them and the red led lights are not on.

So far I have checked.

1. All the fuses in the control panel and the fuse spur underneath all okay. (tested with multimeter)
2. Measured the 12v wires on each PIR sensor and they are getting 2.5v (which seems wrong)
3. Double checked I have wired the new one up.
4. Alarm battery is okay and getting 13.8v replaced new 4 weeks ago.
5. Transformer is outputting 20.5v AC
6. Traced the 12v green/white wires back to the control panel and measured the voltage from the terminal and it shows 2.5v.

I can not remember the last time I saw the PIR sensors flash red but we went out yesterday and set the alarm okay. Now today when I set the alarm the 4 red lights light up for 1-4 sensors but instead of the usual exit beeps I just get 4 beeps repeated. I have now found out this is because the Alarm is detecting the 4 PIR sensors are not available, probably due to no power/low power.

So as far as I can tell the 12v aux output terminals from the control panel are outputting 2.5v not 12v ? Does this look like the problem and it needs a new Control Panel ? Is there anything else I can test.

 

Noticed the Control Panel has 2002 on it !

Thanks for any help in advance.

How old is the battery?

 

Try disconnecting it and see if the voltage rises

 

Disconnect all the 12v from the panel and measure the voltage again, if it's 12v then connect them one by one until you find the one that's dragging it down and start there. 


Nothing is foolproof to a sufficiently talented fool.

Maybe the cable at conservatory has been damaged and now shorting out the supply 

 

So if fuse is ok possible panel damaged , but that won't resolve the issue replacing panel if cable still has a problem

Disconnect one leg of the wires from the panel and see if the voltage goes back up to 12v, if it does put the cables back one by one til the voltage drops and you have then found the cable with the problem. You then need to follow the cable route to fined where the cable is damaged
