CIRCUITS & ZONES
FIP End Inputs
The "off", "auto" and "on" inputs from the AS1668 Control Module can be connected to 0, 1
or 2 AZCs as desired.
One AZC per fan control is cheaper, but does not allow the LCD zone text to display "fan off"
and "fan on", though the fan name can be put in the zone text, and for options A and C
following, the word "off" could be programmed as zone text so that "Manual" Alarm is "on"
and "off" Alarm is "off".
For option B, the text LCD would display "fault" for "off". Zone text would normally only be
viewed by a zone status recall as AS1668 control inputs will (generally) be programmed as
"status" zones (i.e. non-FFCIF).
Figs 6.1.3 and 6.1.4 show both options. Option 1 requires a Zener diode or a resistor (e.g.
560E) to give B2 voltage.
Note that the option shown in Fig 6.1.3 B ("off" <-> "fault") corresponds to the standard
KT0113 AS1668 Module circuits (see drawings 1945-19-3 and 1945-19-4) and so is the
"preferred" option for using KT0113.
