Hills r8 issues with reed zones on 5,6,7
Morning all, hope everyone is well
You guys have been a big help to me in the past with a couple of alarms, hoping you can help again
I work in the electrical maintenance field for mainly rentals properties.
Im not an expert on security systems but i do know a little just to get me by as part my role is to get alarms going for tenants of my clients when moving into properties. I work on alot of different of brands and models, so it is a little hard for me to get familiar with specific panels, and sometimes it a year or so that i work on the same model/brand panel.
My brother just bought a property and it has a Hills R8.
Of course the agents didnt pass on the user codes, so i told my brother not to worry, ill reset the panel and we will program it to his needs
So ive done that, and have got pretty much everything working.
However i got stuck with zones 5, 6, 7 not working at all
Zone 5 laundry reed
Zone 6 sliding door reed (which im still yet to find where the reeds actually are)
Zone 7 Windows reed (must be done in series, because there is 3 i believe)
I realized a week later. zone doubling!
So i went back last night, turned zone doubling on via Feature 22 Segment 5 option 2, checked the zones for 5, 6, 7 They are set to 16 like all the PIRS except entry PIR
But zones 5, 6, 7 keep flashing continously on keypad
Any ideas?
Thankyou in advance

If the zones a flashing they are unsealed, check that the magnets a there and line up with the reed switches.
Use a multimeter to check the resistance of the alarm pair at the panel end wires.

Thankyou Secure,
I thought i done something wrong programming to be honost
Ill check the magnets in next couple days, and check the ohms on the cables for the 5 6 7 zones at panel.
From memory, the resistor would be at the reed/pir side?
Normally at the reed / pir end.
Otherwise it could be in the panel where it connects to the main board if it was done by a lazy installer. Not good practice.

Hi Secure,
i went back to my brothers, and opened up the panel,
Found 2 wires on zone 1 (which on doubling is zone 5) , but only 1 wire on zone 2,3,4 (zone doubling = 6, 7, 8)
Which means that the keypad was labelled incorrect.
Looks like there is no sliding door reeds, and the windows and laundry reeds are all connected in series on zone 5
I reprogrammed zone 6 and 7 to disabled
I checked the windows the magnet was missing on 2 of thew windows, so i put a magnet on both of them, and sure enough zone 5 stopped flashing
Thanks very much for your help with this, much appreciated
Also there was no resistors at the panel, except for zone 5 (which is the reed switches), so looks like the installer wasnt too bad in that case.
However, may i ask for my own knowledge why its better practice to have the resistors at the PIR side. Is this so you can also wire in the tamper on a pir still with 4core ( blue, white, + red - black)
Thanks for your time again secure, been a great help now and in the past

Best for resistor to be at sensor end to be more effective. Not just because of tamper. The resistor is also protecting the cable for shorts / open circuits.
I can understand why resistor was put in panel on zone 5 for easy fault finding otherwise you would need to pull apart each sensor to check which had the resistor.

Thanks secure, ill wire them up the way u recommended
After thinking about it, i finally understand the diagram with the 2 resistors. With the 2 resistors, its making the tamper a different zone by using the same cable as the resistor ratings being different would make 2 zones per PIR, Which means you will chew up alot of zones by doing it that way. 6 pirs would become 12 zones! There is a benefit in that way, cause you could have the tamper on 24h zone. But i think in domestic situation its not needed. With the 2 resistors/zones, it must be more for a commercial situation, so the tamper is on during the day when unarmed but the pir wouldnt be
thanks again for your help secure
