CIRCUITS & ZONES (CONTINUED)

R5 = Z15D + Z15N.Z5A.^ (Z1:4(1)A+Z6:10(1)A)

Note also, that if the interposing relay (fan control input) is 24V at less than 100mA then an open collector (O/C) may be used as per circuit 1 of 1945-1-1/4 following.

9.1.4LEDS

The 3 LEDs may be: switched directly as per circuits 1 and 2 of 1945-1; driven off 3 open collector (O/C) outputs or driven off 2 O/Cs with a Zener diode as shown in Fig 9.1.6 and 1945-1-3. Note that where the FIP has a number of detector circuits, the open collector outputs associated with these AZCs may be used for driving the AS1668 LEDs and so it doesn't matter if the AS1668 panel requires more open collectors than circuits.

For other LEDs (eg. Chrome Bezel LEDs) a lower value (higher current) resistor may be required.
