product was developed to meet rigorous demands of military and civil aircraft mis‐ sions, operating in extreme conditions. Its rugged construction with long‐range capability and semi‐duplex communica‐ tion integrates the external operating crew as a component of the aircraft inter‐ com system and provides increased situa‐ tional awareness and safety.


About the Polycon Wireless Intercom System


The Polycon communication system was developed by professionals, for pro‐ fessionals and its superior performance and unique patented features are unmatched by any competitor. The Polycon system was also developed in close cooperation with specialized Search and Rescue (SAR) teams. The system fully integrates the external operating crew into the aircraft intercom system and pro‐ vides increased situational awareness and constant un‐interrupted communication


between crewmembers, which is critical to mission execution. The Polycon system has become standard equipment in SAR helicopters from major European helicop‐ ter manufacturers and other aircraft OEMs.


Features include:


1. Wireless Intercom Extension through the Aircraft Intercom System (ICS)


2. Waterproof Design (1m) 3. Rugged Construction 4. Long Range (10‐15 nm) 5. Effective Noise Canceling Technology


6. Hands‐free Operation 7. Accurate and Dependable Voice Activation Technology


8. Casualty Communication 9. Multiple Aircraft Certifications 10. Small Physical Size (Base Station & Transceiver)


The System provides semi‐duplex com‐ munication, based on 16 optional channels


(Standard 409 – 419 MHz, UHF). Additionally, the system provides two operational modes, PTT operation or ‘No Interrupt’ Voice X‐mission (NIVOX) activa‐ tion and allows for TX output power adjustment up to 0.5 W.


The mobile transceiver is waterproof to 1 meter (3 feet), or up to 24 hours in a sub‐ mersion vest.


With its integral microphone built into the mobile transceiver, helmet or headset removal is not required to speak to a crewmember or casualty/patient. Its unique patented antenna (isotropic radia‐ tion non‐directional) provides outstand‐ ing performance, and a typical range with external antenna is up to 10 – 15 NM, or line of sight. No other brand of wireless intercom has this capability.


The Aircraft Mounted Base Station is qualified to RTCA DO‐160D, with installa‐ tions flying on the most popular SAR Helicopters, such as the EC135, EC145 (similar to the UH‐72A), AS332L2 / EC225, S‐76, S‐92, and AW139. ◆
