hi

i have just purchased and fitted an old scantronic 9450 panel for my shed with a couple of probems.

i have conected one door sensor to ee and one to zone 2. all others are looped out but when i try to set the alarm the tamper fault lights up. can anybody give me a clue what might be causing this?

also the bell supplied which was aparently connected before the system was stripped out is a bell with only 2 connections. can you confirm what these should be connected to? i have them connected to BELL and +12v which is working.

i am guessing that there shoud be a tamper for the bell looped out but what should i connect?

any help would be greatly appreciated

steve

If you are not using a bell tamper , then you must link out the tamper circuit, place a link between 0v and TR.

In the middle of the main circuit board, turn up the volume pot.

ok thanks. i would prefer to fit a new one inside the panel (it is 50mmdia). i have done a search but cant find one. could you point me in the right direction?
the instructions refer to a 9040 speaker which would be outside the panel but the 50mm one looks like it was allways there, it is clipped into lugs in the back of the panel. would i be able to fit 2 speakers so one could be wired to inside the house?

If your willing to spend money get a better alarm panel.
