Figure 16– Sounder Wiring
Terminate the Sounder circuit wiring at the Filter PCB installed at the left-hand side of the inside
of the top cover of the back box. Refer to the figure at the top of the previous page for wiring
connection details to the Filter PCB.
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.
Always check that conductors of appropriate diameter are used so that the voltage of all
sounders is within the manufacturer’s specification when the panel is operating under AC Mains
failure and minimum battery voltage conditions (Refer to Table 11 – ZX1Se / ZX2Se Power
Supply and Charger Specifications and Table 12 - ZX5Se Power Supply and Charger
Specifications for minimum panel output voltage).
