Figure 15 – Sounder Wiring
DO NOT loop wiring under any terminals. Break wire run to maintain supervision.
•
Cable runs in excess of 1km (3200’) are not recommended. Otherwise, the capacitance and inductance of
the cable may affect the performance of the system. For systems with Nittan detectors, cable runs should
not exceed ½ km (1600’).
•
Always check that conductors of appropriate diameter are used so that the voltage of all sounders is
within the manufacturers specification when the panel is operating under AC Mains failure and minimum
battery voltage conditions (Refer to Table 10 & Table 11 for minimum panel output voltage).
