25.5.10 Discrete Outputs
The GEA 24 has 2 annunciator outputs, these outputs do not require any configuration and can be
optionally wired to an external annunciator. Discrete Out 1 acts as a master warning annunciator and is
active any time a warning CAS message (Red Alert) is displayed on the PFD. Discrete Out 2 acts as a
master caution annunciator and is active any time a caution CAS message (Yellow Alert) is displayed on
the PFD. Reference Section 29
for wiring guidance.
DISCRETE OUT 1 is "master warning" - goes low when a red (warning) CAS alert is active.
DISCRETE OUT 2 is "master caution" - goes low when a yellow (caution) CAS alert is active.
The two states of these outputs are as follows:
INACTIVE: Floating (can be pulled up to externally sourced Vout in the range 0 Vout 33 VDC)
Leakage current in the INACTIVE state is typically 10 uA to ground
ACTIVE: Vout 0.5 VDC with 20 mA sink current
Sink current must be externally limited to 20 mA max
If two EIS LRUs are configured, use annunciator outputs on EIS LRU#1 only.
25.5.11 Fuel Quantity
Fuel Quantity inputs have an internal pull-up resistor that can be enabled for resistive fuel sensor inputs.
The inputs can also support capacitive sensors as either voltage inputs or digital inputs. These inputs are
configured by the GDU (refer to Section 33.4.19
for GDU 37X systems and to Section 34.4.26 for
GDU 4XX systems).
