Basic Functions
Feature Description
Carbon Monoxide (CO)
detection
The system generates an alarm when the CO level rises above 50 parts per
million (PPM) and stays above this level for 3 min 30 seconds. The alarm
operates without any delay in case the CO level rises above 400 PPM. Data
is transmitted via an RS 232 port and a remote warning light is switched on
in case of CO crossing threshold levels.

This light will be switched on when the CO level is detected above the
designated threshold.
This warning light will alert the pilot at preset cabin altitudes of 10,000
feet, 12500 feet and 14,000 feet AMSL.
FMS 65X and 85X generates a tone and sends it to the aircraft audio
panel whenever an alarm condition exists.
FMS 65X and 85X unit interfaces with the RS 232 data bus and is able to
access a large number of aircraft parameters. This data can be transferred
via a Bluetooth connection (Not current available) to as many as six iOS
devices simultaneously. These devices include iPhones and iPads.
Data transferred via Bluetooth (Not current available) can be viewed in real
time over iPhones or iPads inside the aircraft.
The unit can be reset remotely either by a hard wire reset or via the RS232
data stream.
The unit has two USB ports. These can provide 2.5 Amp power each to two
smart USB devices. In case the unit is connected to a non-smart switch, it
will be able to provide 1 Ampere continuous power supply.

System Description
1.0 General
Carbon Monoxide (CO) can be dangerous in an enclosed space such as an aircraft cockpit. The
FMS 65X and the 85X series products are designed to be installed in the instrument panel of an
aircraft. It is designed to detect the presence of CO concentrations before they reach life threatening
levels. In addition, the FMS 65X/85X can connect to the RS232 data stream and provide real time
engine and GPS data to occupants in the aircraft who may be using iPad(s) or iPhone(s). The data
can later be uploaded to a secure cloud-based server.
