sab or scb ?
Hi,I'm fitting two new external sounders to my existing control panel,that I'm wiring in series.Do both sounder's have to be set on SAB or can I have sounder one on SCB+ sounder 2 on SAB?.
It is a none monitored system,also I would like the option of using the activeguard (none standard) wiring method,thanks.
