CAST ZFP Analogue Addressable Fire Alarm Panel

Fig.14 – Z16 Zone Sounder PCB Wiring

Note: The Z16 terminal labelled 'Ex' is used to report a fault from the AUX (external) PSU. It is triggered

from an active IO signal from an open collector (O/C), or volt-free (with 0V common) relay O/P.

If an AUX (external) PSU is not used, a link must be fitted between PCB terminals 'Ex' and '0V'.

Correct polarity must be observed.
