(b) Test Procedures
1
Set the switch on the control panel of the transmitter unit to “ARM”.
NOTE:
The applicable G-switch must be selected using an external wiring
link. To select European G-switch (JAA G-switch), insert a shorting
link between pin J1-14 and pin J1-16. To select North American G-
switch (FAA G-switch), insert a shorting link between pin J1-15 and
pin J1-16 (refer to Table 102).
2
Activate the ELT by using a quick throwing motion in the direction of the
arrow, followed by a quick motion in the reverse direction. Verify the unit has
activated by observing that the LED on the control panel is blinking (signifying
activation).
3
After verifying operation, set the switch on the control panel of the transmitter
unit to “OFF”.
(7) Verification of Digital Message, Test # 7
(a) Equipment Required
Commercially off-the-shelf 406 MHz Digital Message Decoder, such as the
Sartech Electronics, Portable Test Set Model ARG5410 or the Honeywell Rescu
406
TM
Test System, or the WS Technologies BT100S/A/D.
(b) Test Procedures
1
Connect the RF output of the transmitter unit to the RF input of the Digital
Message Decoder via a co-axial cable.
2
Set the switch on the transmitter unit to “TX” and wait for a 406 MHz pulse to
occur.
3
After the pulse has occurred read the digital message on the screen of the
Digital Message Encoder and verify the following:
a
If the transmitter has been removed from an aircraft installation with no
AIM or NAIM attached, then the 15-HEX code shall be as shown on the
transmitter unit label and the total message shall be the 112-bit format.
b
If the transmitter unit has been removed from an aircraft installation with a
programmed AIM, then the 15-HEX code shall be as shown on the AIM
unit label and the total message shall be the 112-bit format.
c
If the transmitter unit has been removed from an aircraft installation with
an AIM programmed with the NULL message protocol and a 24-bit DIP
switch module with a valid 24-bit aircraft address connected to the AIM,
then the 15-HEX code message shall be according to the dip switch
message, and the total message shall be the 112-bit format.
