Product Information

MSA’s new ICM Tx Integrated PASS combines the safety features of the ICM 2000 Plus integrated PASS with the functionality of the Heads-Up-Display (HUD) transmitter in a new integrated PASS device that’s fully compliant with the latest requirements of the NFPA 1982-1998 edition PASS standard.

Because it is now a single component on the Air Mask, firefighters benefit from a more compact and lighter weight 1/3 lb less!) design. MSA has also standardized on a single battery type for both the ICM Tx and HUD facepiece-mounted receiver, the commonly available AA alkaline battery, which provides up to twice the life of the previous 9-volt and AAA batteries, which makes for fewer change-outs and easy ownership.

A New Motion Sensor
The ICM Tx has been designed for maximum reliability and durability with the use of a new solid state accelerometer to detect the motion of a firefighter. Accelerometers, which are resistant to the wear associated with mechanical components, have been used successfully in the automotive industry for years. They consist of a dual-axis electronic sensor which converts changes in momentum, through the flexing of an internal oscillator (pendulum), to changes in voltage, which is interpreted by the microprocessor as motion. The use of this technology provides a device that is sensitive to motion and resistant to false alarms, with a level of durability that meets the rigorous demands of the fire service.

To increase the visibility of firefighters, the ICM Tx incorporates a ”buddy light”. When the ICM Tx is in the monitor mode, a bright green LED flashes behind the translucent manual PASS alarm button. When the PASS goes into full alarm, the light turns red for quick recognition of a firefighter in distress.
