    Scantronic 500r - Weird Alarm Noise

    Just realised after looking at the photo of the bell box above that there appears to be a battery contained within it. This will be about 20 years old and has never been changed and so could this be the reason for the lack of external alarm and strobe ? The alarm system has been switched off...

    Scantronic 500r - Weird Alarm Noise

    Hi Sparkymarka, sorry for delay in replying. Swopped the blue and yellow wires over but the external alarm still didn't trigger. I've been up the ladders and opened up the bell box, photo attached, but all looks in order although clearly I'm no expert. I've completely reset the whole system by...

    Scantronic 500r - Weird Alarm Noise

    Sorry, yes the control panel is open when I key the commands. I just don't understand why the external siren doesn't trigger even though it works when you put the blue wire in the 0v. Its therefore live and that's why I'm convinced there's something very simple I'm overlooking.

    Oh, no, I've not opened the external bell box at all if that's what you mean ? All I've done is through the programme mode on the control panel.

    Scantronic 500r - Weird Alarm Noise

    When in programme mode the lid is always open. Like I say, it all sets and triggers with the sensor but for some unknown reason the external siren and strobe don't activate.

    Scantronic 500r - Weird Alarm Noise

    I left the strobe wire in the 0v for several minutes but the strobe still didn't activate. I've reset the bell delay to nil by keying 91 Omit Reset and Reset again and whilst the alarm all sets, only the internal sounders are triggered and the external one is silent even though I know it works...

    Scantronic 500r - Weird Alarm Noise

    Hi, I took the blue wire out and touched the black 0v and sure enough the external bell started to ring. However, when I did the same with the yellow wire and touched the black 0v nothing happened and the strobe didn't come on. I'm sure there isn't that much wrong with the alarm, despite its...

    Scantronic 500r - Weird Alarm Noise

    Hi Sparkymarka, replaced the fuse today and the ticking has stopped and when triggered the internal alarm now goes off as it should. However, the issue now is that the external bell box and strobe still don't trigger. The fuse I used was 500ma but it was a slow blow fuse. Would this make a...

    Scantronic 500r - Weird Alarm Noise

    Hi Sparkymarka, just had a closer look at the control panel and it looks like the fuse for the siren may have blown. This would explain why the external siren isn't triggered but could this also explain the ticking and why the strobe isn't flashing outside ? Going to order a new fuse but would...

    Scantronic 500r - Weird Alarm Noise

    Hi Sparkymarka, I've followed your instructions and removed the red/white and black wires and then linked 0v to TR with a piece of wire and whilst the ticking does initially stop, once you reconnect the mains then it starts again. I've also noticed that when in program mode the system doesn't...

    Scantronic 500r - Weird Alarm Noise

    Hi Sparkymarka, thanks for the prompt reply. So I remove the blue Bell and black 0V cables but how do I link the empty 0V to the Tamper Return TR ? Do I just use a small piece of wire from the 0V to the TR and then try and reset the system ? If this does stop the ticking noise then do I then...

    Scantronic 500r - Weird Alarm Noise

    Hi Sparkymarka, the bell box is probably about 20+ years old. I won't be able to post a picture until later in the week but are you suggesting that the connections within the box have possibly corroded ? If so, is it just a case of cleaning them up, reattaching and then hoping for the best ? If...

    Scantronic 500r - Weird Alarm Noise

    I recently reset my Scantronic alarm and have renewed the battery as this was several years old. Having relearned the sensors, the alarm sets correctly but when the sensor is triggered, the outer alarm box and strobe aren't activated and instead the internal alarm makes a weird squarking noise...
