ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) DESCRIPTION AND OPERATION TASK 25-62-03-870-801 1. Description SUBTASK 25-62-03-870-001 A. Functional Overview (1) (2) The ELT automatically activates during a crash and transmits the standard sweep tone on 121.5 and 243.0 MHz. Approximately every 50 seconds, for up to 520 milliseconds (long message protocol), the 406 MHz transmitter turns on.
PAGE 28
ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) (7) Aircraft communications transceivers are not capable of receiving 406 MHz transmissions; therefore, the only methods of monitoring the ELT are: (a) The cockpit remote switch panel light, (b) The buzzer, or (c) 121.5/243.0 MHz transmissions, which can be monitored using the aircraft communications transceiver or an AM radio tuned to 121.5 MHz. SUBTASK 25-62-03-870-002 B.

ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) (2) The cockpit-mounted Control Panel G737 (remote switch panel assembly) is a backlit panel comprised of an ELT status indicator light and a control switch, which allows an operator to manually activate the ELT for testing and reset (i.e., deactivate) the ELT. See Figure 2. Remote Switch Panel Assembly Front View. NOTE: The ELT CANNOT be disarmed or disabled from the cockpit.

ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) (5) Five dual-input antennas are approved for use with the B406-4 ELT. Selection of the proper antenna is dependent upon end use, aircraft configuration, speed, and other factors. See Figure 5. Antennas. 110-320 110-333 110-328-01 110-337 110-337-11 Figure 5.

Operational Overview (1) See Figure 6. ELT Operational Flow Diagram. (2) A primary feature of the B406-4 ELT is its simplicity of operation. As long as the ELT is connected to the remote switch panel harness ELT connector, such that pins 5 and 8 are jumpered (G-switch loop), it will activate in the event of a crash.
PAGE 32
ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) “ACTIVE” state requires a positive switch transition from either the cockpit remote switch, ELT local switch, or G-switch. NOTE: It is possible the G-switch could activate the ELT as the result of severe maneuvers or a very hard landing. (6) To take the ELT from an “ACTIVE” state back to an “INACTIVE” state, a “RESET” must occur. See SUBTASK 25-62-03-870-004.

ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) NOTE: The buzzer may be located anywhere in the aircraft; however, the recommended location is near the ELT, as the buzzer is loud enough to be heard outside the aircraft when the engine(s) is not running. When the engine(s) is running, the LED on the cockpit remote switch panel will warn the pilot the ELT is active. SUBTASK 25-62-03-450-002 B.

ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) NOTE: Prior to installing the 12-pin ELT receptacle onto the harness, the wires connecting to the ELT must be routed through the rectangular hole in the ELT mounting frame cap. The cap retains the receptacle when installed and the receptacle will not fit through the mounting cap harness entrance. (3) Feed the buzzer wire (YELLOW) on the ELT end through the mounting frame cap.

(12) Tie up excess slack in the harness and coax cables, such that they form drip loops and there is enough slack, approximately 5 in. (127 mm), to allow the mounting frame cap to be easily pulled back.

ACR ELECTRONICS, INC / ARTEX PRODUCTS DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL B406-4 (453-5004) (7) Reset the ELT by toggling the ELT local control switch to “ON” and back to “OFF” after 1-2 seconds. NOTE: This step is necessary because the ELT will occasionally activate when power is connected to it in Step 6. (8) Fit the battery pack into place on the ELT, while dressing the wires away from the standoffs to avoid pinching the wires between the standoffs and battery pack.
