I. Remote Audible Alarm Panel
The remote audible alarm panel (buzzer) generates an audible tone of intensity greater than 75 dB
ambient when the transmitter unit has been activated and is in the TRANSMIT mode.
8. Operational/Maintenance Modes
The transmitter unit may operate in any one of four modes: OFF, ARMED, SELF TEST and
TRANSMIT. The ARMED and TRANSMIT modes are the operational modes while the OFF and SELF
TEST modes are the maintenance modes.
A. Operational Modes
(1) ARMED Mode
In this mode some of the transmitter unit circuits are powered up so that it can detect an
activation signal from the G-Switch (automatic activation), the remote panel, or the
transmitter unit panel (activation switch and LED). Upon receiving an activation signal in
the ARMED mode, the transmitter unit will switch to the TRANSMIT mode and begin to
transmit 121.5/243 and 406 MHz signals.
(2) TRANSMIT Mode
(a)
(b)
B. Maintenance Modes
(1) OFF Mode
The power from the battery pack to the transmitter unit is completely cut off and none of
the circuits in the transmitter unit are powered up. The transmitter unit is incapable of
sensing a crash or transmitting.
(2) SELF TEST Mode

In this mode the transmitter unit has been activated and is transmitting 121.5/243
and 406 MHz signals to the antenna.
The first 406 MHz pulse will be transmitted approximately 50 seconds after
activation and then subsequently at 50-second intervals. Each pulse will have the
selected protocol format.
A momentary 5-second state. After completing the self-test, the unit will
automatically return to the ARMED mode.
A 121.5 and 243 MHz pulse will be transmitted to the antenna for approximately
0.5 second.
A single 406 MHz pulse coded as a self-test signal will be transmitted
approximately 3 seconds after activation.
