Fault Output:<br />
Relay 1 is configured<br />
for failsafe operation<br />
as standard.<br />
• The ZX1Se, ZX2Se and ZX5Se <strong>Fire</strong> Alarm Control <strong>Panels</strong> have<br />
two unsupervised relay outputs, with volt-free (dry contact),<br />
changeover contacts. The ZX10Se has four of these relays.<br />
• The contacts are rated at 30V AC/DC, 1 Amp.<br />
• Relay 1 is normally held in an energized state. It will de-energize<br />
under fault conditions.<br />
• Terminate the Auxiliary Relay circuit wiring at the Filter PCB installed at the left-hand side of the<br />
inside of the top cover of the back box. Refer to the figure below for wiring connection details to<br />
the Filter PCB.<br />
