Alarm wiring for dummies 101

[Peter12345678]

Hi everyone.

I’m am in the process of wiring in an alarm system.
Accenta g4 alarm panel with a reson8 bell box.
Unfortunately nothings working, ie no red LED and no green LED.

The wiring connections are:-

Strobe- on panel to stb- on bell box
T on panel to rtn- on bell box
A on panel to hold off- on bell box
D on panel to hold off+ on bell box
B on panel to trig on bell box

I am trying to work out exactly how the connections work.

Am I correct in the following.

Trigger (B), no alarm 12V, alarm condition 0v
Strobe, no alarm 12V, alarm condition 0v
A and D 12 volt supply, should always be at 12V
T, on the Reson8 this is lust a loop, from hold off – to rtn. Thus it returns 0V, from A, back to the control panel T.


Thanks, in advance for your replies.
