Taylor47 Posted January 11, 2008 Posted January 11, 2008 Hi. I'm 'brand new' to this site, so I hope that this topic thread is set up OK... I have a Scantronic 9452 wired house alarm (fitted around 15 years ago, but been ultra-reliable up until now). A couple of the room sensors have recently gone 'dodgy' - they light up, they 'register' as being active on the zone board, yet the house alarm doesn't actually fire off when these sensors detect movement in those rooms. They aren't part of the zone we can 'omit' on the night-time setting, so I'm really at a loss to know what's up...! If anyone can suggest anything, I'd really appreciate it. Thanks in anticipation...
Guest anguscanplay Posted January 11, 2008 Posted January 11, 2008 who`s been working in the house recently ?
spider Posted January 11, 2008 Posted January 11, 2008 What do the detectors look like, are they rectangular cream units with a black square window with the led in the bottom right corner?

Thanks in anticipation... a system this old needs a maintenance visit by a decent engineer as your external siren may be duff, meanwhile, how are you testing them? are you using the walk test facility available? if not you need to fully arm your system and then trigger the detectors one by one as they may be programmed as an 'access' zone (i.e. one you can walk through after opening the front door) sometimes done to reduce possible user mistakes or the risk of the kids racing in before the alarm is switched off. it's not what i would do - as i'd simply beat the living **** out of the kids up, but what i have seen done by other installers regs alan If you think education is difficult, try being stupid!!!!
Taylor47 Posted January 12, 2008 Author Posted January 12, 2008 What do the detectors look like, are they rectangular cream units with a black square window with the led in the bottom right corner? Thanks for taking the time to reply to my thread - I appreciate it. In answer to your questions, having now taken a closer look at the sensors, they are cream coloured, about 9cm x 5cm, with a 4cm x 4cm, convex translucent plastic LED cover. The LED itself seems to be centre, bottom of the cover. Also, whilst it's not that clear to read, the wording on it looks like ROKONET...? Does that help? Any ideas? I wondered if, somehow, we'd managed to "omit" the sensor zone, although, as far as I know, we're only able to 'de-activate' the upstairs sensor for night-time. Anyhow, any advice would be welcome. Thanks again and hope to hear from you.

It's only the front door 'switch' that's our access - everything else is completely 'live' once the alarm is fully armed. We've tested various sensors, upstairs and down, by setting the alarm and entering the rooms - they all fire off the external ringer (so that definately works OK) except for these 2 room sensors I'm concerned about. That's why I can't get my head around it... Anyhow, any advice would be welcomed. Thanks.

That's why I can't get my head around it... Anyhow, any advice would be welcomed. Thanks. to be clear for your full understanding, the front door is a final Exit/Entry zone not an access zone, a pir in the hall would be on an access, otherwise the hall the pir (if fitted) would cause an alarm every time you entered. if an intrusion was made other than by the front door the hall pir would alarm immediately on detecting an intrussion. you say these detectors are indicating on your control unit, that would tell us the pir's and cables would seem to be ok (so i don't know why Angus keeps asking who has worked in the house recently ). that leaves us with the possibility these zones are either not programmed properly so won't act in alarm, or the panels has gone faulty. if they have been proven to have worked properly in the past then the obvious conclusion is a faulty panel. or has someone tinkered with and altered the programming? we understand especially after christmas (and before the credit card bill comes in ) nobody wants to fork out for what might be a 'simple' fault, but if you consider you have had 15 years out of your system cost free and many pay an annual fee for maintenance, you really are quids in. so i recommend you spend a few bob and have your security properly looked by a professional is my advice - before your broken into and loss all you saved on. regs alan If you think education is difficult, try being stupid!!!!
