or maybe you are thinking of those cheap stand alone panels of yours with the on board speakers which are mounted near the front door you seem to favour lol. you make laugh nick you really do.
see nick, us bona fide alarm engineers use good quality end stations (scantronic) with remote keypads. this means you mount the keypad near the front door, then hide the main panel anywhere. then you buy a seperate 16 ohm speaker (elmdene) which somewhere central in the house. no one will know where the panel is. how is a speaker in a hall going to tell you where the main panel is?.
as for the texecom oddysey judging by your post and lack of knowledge on alarms i wouldn't be surprised if you connected the battery to the piezo terminals potentially f***ing up the unit then wonder why it does not sound.
