I agree with Alarm.
You could of least listed the terminals at the sounder because I for one have never used pyronix deltabell's.
Alarms description was spot on in concept unlike mine,I've given you the basics but it's now up to you to revise the "link" refit and complete the tamper circuit.
A little understanding is needed on your part to ensure a fully functional sounder.
Look on the sounder and you will see two TAMP terminals the second one down is the RETURN,have a think about the link?,
TAMP to B- or TAMP RETURN to B- ?? Just have a think about it as I'm not in the habit of giving out a full tamper completion circuit.
