2. Operation
A. Overview
1) A primary feature of the ARTEX ELT 1000 is its simplicity of operation.
2) A connection jumper (“G-switch loop”) between pins 5 and 12 on the connector enables the G-switch
circuitry, allowing activation when the acceleration threshold is exceeded. The jumper is located in the
mating connector of the cockpit remote switch wire harness. When this connector is removed, the ELT can
be manipulated without the possibility of activation.
3) With the G-switch loop in place, neither the cockpit remote switch nor the ELT local switch can be
positioned to prevent automatic activation. With the G-switch loop open (removed), the ELT cannot be
activated by dropping, rough handling or during shipping.
4) Activation is indicated by the presence of the swept audio tone transmitted on the 121.5 MHz signal, the
buzzer sounding and the flashing cockpit remote switch and/or ELT local LED. All these indicators
immediately begin upon ELT activation.
5) To deactivate the beacon, either the position of the local ELT switch or the cockpit remote switch must be
changed from “ON” to “ARMED”. If activation is from the G-switch, the switch position must first be set to
“ON” then changed to “ARMED”.
NOTE: The ELT CANNOT be disarmed or disabled from the cockpit. Cockpit operation is limited to
activating and resetting the ELT.
6) A warning buzzer is required by TSO C126a to indicate ELT activation when the aircraft is not operating.
The buzzer is powered by the ELT and is not dependent upon the aircraft power for operation. The
indicator ‘beeps’ periodically, with the periods between pulses increasing after 12 hours.
B. Normal Operation
NOTE: The beacon will immediately begin transmitting at 121.5 MHz and will continue to do so until
the ELT is deactivated or 24 hours have expired.
NOTE: The beacon will begin transmitting at 406 MHZ approximately 50 seconds after activation
and will continue to do so at approximately 50 second intervals until the ELT is deactivated
or 24 hours have expired.
1) In normal operation, the ELT is “ready to activate”. The cockpit remote switch and the local switch on the
ELT are both in the “ARM” position. The G-switch loop (connection jumper between pins 5 and 12 of the
connector) is in place to enable the ELT. In this condition, if the ELT movement causes the G-switch
threshold to be exceeded, the beacon will activate.
C. Manual Activation
1) The ELT may be manually activated by placing either the remote switch or the ELT local switch in the “ON”
position. This forces the ELT to activate, regardless of whether or not the G-switch loop is in place.
NOTE: The ELT cannot be reset if either the cockpit remote switch or the ELT local switch is in the
“ON” position.
D. ELT Reset
1) If the ELT is inadvertently activated (for indications, see 4) above), reset it by moving either the cockpit
remote switch or the local ELT switch to the “ON” position, and then move it back to the “ARM” position. If
the switch is already in the “ON” position, move it to the “ARM” position.
