Hi got a concept alarm that is in a rented property. About 2 years ago I got a call from the occupiers who said that the alarm was going off in the night and they silenced it not sure what they done (altough on recent inspection it looks like that have removed one wire from the internal optional sounder and placed one of the others in the stobe output! Note they were not using the alarm so it was always in day mode.
I now have a new person moving in who wants to use the alarm. All appears to be working although the battery is obviously had it but the charging circuit is only outputting 7v (I guess roughly half what it should). And also the internal additonal speaker is not working when wired across the speaker output.
Also there is a funny aditional box that one of the zones goes through
Attached is the inside of the panel (note the burnt out resistor anyone know the value of this?) and also the additonal box that I dont know what it is for (appears to have a pot in it and also some Jumpers).
Any help v much appreciated.
