ARTEX AIRCRAFT SUPPLIES, INC. 570-1600
6. Specifications
6.1 Operating Frequencies
406.028 or 406.037 MHz +/- 1kHz (consult product label for frequency)
Modulation: Bi-phase L (emission designator G1D)
121.5 MHz +/-6.075 kHz
Modulation: AM (emission designator A3X)
6.2 Output Power
406 MHz: 37 dBm ± 2 dBm (3.2W Min to 7.9 W Max) (440 ms / 50 sec
period) PERP or EIRP for 24 hours @ -20ºC to +55ºC
121.5 MHz: >/= 17.0 dBm (50mW Min) PERP for 50 hours @ -20ºC to
+55ºC or >/= 20.0 dBm (100mW Min) EIRP for 48 hours @ -
20ºC to +55ºC
6.3 Activation
Crash sensor (G-switch) velocity change of 4.5 ft/sec (2.3Gs)
NOTE: The crash activation level specified by RTCA/DO-204 §2.2.3 is 3.5 ft/sec (2.0
Gs); Artex has specified the higher threshold of 4.5 ft/sec (2.3 G) in accordance
with Eurocae ED-62. The use of the 4.5 ft/sec (2.3 G) crash sensor has been
approved by the FAA as a deviation (FAA Reference # 98-130S-108, dated
February 6, 1998).
5 Auxiliary G-switches activate at 12 Gs in addition to the main G-switch for the ME406HM.
NOTE: It is possible that either the primary or the 5 auxiliary G-switches may activate as
the result of a very hard landing of a fixed or rotor wing aircraft.
6.4 Temperature
Storage: -55ºC to +85ºC
Operational: -20ºC to +55ºC
6.5 Input Power
ELT: none
Remote Switch: +28VDC, 30 mA (max) or +14 VDC, 30 mA (max)
The remote switch will function without aircraft power but the LED requires voltage.
