EBC 406APH – AUTOMATIC PORTABLE HELICOPTER EMERGENCY LOCATOR TRANSMITTER
For cabin or cockpit installation in helicopters. Has 720 degree spherical automatic activation. Transmits on 406.028 & 121.5MHz. Meets TSO-C91a and TSO-C126. Approved for use without a remote control monitor.
Product Manual
The EBC 406APH is designed for installation in the cabin section of a
helicopter. It transmits on the frequencies of 406.028 and 121.5 MHz.
The system comes with a transmitter, portable/survival antenna, mounting
bracket, external whip antenna with a 6 foot coax cable, and a battery pack.
The whip antenna can be replaced with a rod or blade antenna if desired.
If the ELT is activated a built-in monitor emits a loud beeping tone and the
LED flashes. The portable/survival antenna allows the ELT to transmit a
good signal when used outside the aircraft. Since it is installed near the
pilot a Remote Control Monitor is not required.
The EBC 406APH is meant to be installed near the pilot. This eliminates the
need for a remote control monitor and thus reduces the cost of installation
and the need to use panel space. This type of installation also allows for
easy removal of the ELT in case of an emergency – just disconnect the
antenna cable and attach the portable/survival antenna after leaving the
aircraft.
Designed with the newest technology, the EBC 406APH also incorporates
the best and proven features that characterize all of EBC’s emergency
locator transmitters. These transmitters have encapsulated electronics and
battery packs to provide added protection against shock, moisture and other
environmental hazards.
The EBC 406APH uses our proven omnidirectional activation system. This
system uses 2 omnidirectional switches mounted perpendicularly to each
other. Since each senses impact in 360˚ the total coverage is a true 360˚
multiaxis activation switch. The switches are connected to a timing circuit
so that only a crash, not a hard landing or vibration, will activate the unit.
False alarms are therefore eliminated.
A self-test feature is built into the EBC 406APH. This feature allows the pilot
to test for output power on both 406.028 and 121.5 MHz, the connection
with the antenna, and the condition of the digital signal. The test is done
directly at the ELT.
The EBC 406APH meets the requirements of TSO-C91a and TSO-C126,
approved by COSPAS/SARSAT and meets FCC requirements under Part 87.
