Hi Guys, 

 

I currently have a 6 year old, wired, Nexus 8 intruder alarm. The PIR in our kitchen was damaged by painters the other day so I am going to have to replace it. My wife's friend works for an intruder alarm company and gave her a Honeywell DT7550UK2 Dual Tec sensor. Was just wondering how I should wire it in? I have attached a photo of the current sensor PCB and the new dual-tech one. 

 

All help appreciate guys. 

 

Best Wishes, 

 

Matthew 

 

 

Attached is a photo of the new sensor!

yellow/green - T1 & T2

blue/white - C & NC

 

take all the jumper pins off the fault, tamper and alarm pins too

Thanks, Mark - that new one is probably to 'high tech' for a domestic. Wouldn't you agree? Ah, well...it was free. 

 

Any tips on how to prevent the alarm going off outside/electrocuting myself? 

 

Thanks!  

open the main control panel, silence the alarm, locate the 12volt aux supply to the detectors (red and black wires), disconnect those, replace the pir, the reconnect them, close up the panel and reset the system. should be good to go!

 

and yes, its a bit overkill,  but for £0 i dont think you can complain

You still need to setup it's range , little grey pot top left , where is the sensor being located in kitchen? Did you get instructions with it? 

Thanks again, Mark! 

 

Al-yeti: it's being located in a corner of the kitchen (the only corner available in the kitchen) - we have a lot of windows though! Yeah - it came with instructions? 

OK look how to set it up and what the pot does adjusts microwave
