Voltages measured at main contacts with mains and battery connected.
• Aux Relay : Dry contacts NO/C/NC
• Fault Relay Output : 13.6v no fault 0v when in fault
• 28v Output : 28.5v approx with no load
• Fire P/E & R/E : -0.6v no fire +28v when in fire
• Loops 1-4 : 0v unused, +22v normal, +24v in fire, +27v during autolearn.
• Sounder 1-4 : -0.6v monitor, +28v when in fire.
Voltages measured at vertical red connector with mains and battery connected.
• +26v to 0v : reads approx +27.8v
• +26v Raw to 0v : reads approx +28.15v
• +5v Printer to 0v : reads approx +5.5v
Voltages measured across battery leads using 6K resistor as load, mains
connected.
• Factory set to give +27.5v
