A Reliable Communication Solution for Critical Environments
The HL-09 SCORPION helmet headset is intended for use on protective helmets in fire departments, police, civil protection, industry, or the defense sector. A wide range of helmet adapters is available for this purpose. The HL-09 SCORPION is also compatible with the CH-71 Milan hand-held microphone speaker.
A high-quality noise-compensating electret microphone and a powerful earpiece ensure reliable communication even in noisy environments. The perception of ambient noise is not impaired.
As befits the headsets field of application, only flame-retardant materials are used in its production. A corresponding helmet adapter is required to mount the HL-09 SCORPION headset to a protective helmet (see AML-1 accessory series).
