hello , can you help me I am not that well up on alarms but can wirestuff up correctly , the problem i have is with my bell box , just moved house and alarm box is knackered , so changing box from a Gardtec 300 series t o a Texecom vertias R8 , on the gardtec system the alarm was wired as such

SAB Tamp yellow

Bell Hold - Black

Bell - Blue

Bell + Red and a White twisted together

Strobe - Green

Strobe + n/c

the connections on my new Texecom are

A permanent positive supply 12v

B Switched negative to activate sounder

C negative tamper return

D Permanent negative supply 0v

S Switched negative to activate strobe

so do I

A Red and White

B Blue

C yellow

D ?????

S Green

do I put D to Black ? don't get this bit , thanks for bearing with me and any advice you give

do I put D to Black

Well done, yeah D to Black

for that , obvious it may of seemed , but can anyone put me straight , when the BELL HOLD wire was removed from the old panel the bellbox sounded , i believe this is in case of a break in & the panel is smashed up , but I thought this was a -12v connection .....don't know where i picked this info up is it correct/incorrect but if its correct then connecting the blue wire to "D Permanent negative supply 0v" on the new panel would not be the same

Point taken Steve - negative 12V and 0V are technically not the same, however, in this case, both panels will be providing a 0V (or negative return or whatever you want to call it) at the specified terminal.

When the hold-off voltage (or the permanent 12V) is disconnected, the bell sounds.

Hope this helps...

thanks for responses , helps a great deal , i know i won't blow the box now ,
