HEADSETS

Firecom offers many different styles of headsets for use with the 3000C Intercom System.
Headsets are available in an Over-The-Head (Figure 19), or Under-The-Helmet (Figure 20)
style. Either of these styles can be Radio-Transmit capable, or Intercom-Only.
For more information regarding the different models of headsets available, contact your
local Firecom Dealer.
RADIO-TRANSMIT HEADSETS
The Radio-Transmit Headsets receive both intercom and radio communications at all times.
The mic is always active for intercom communications. Radio-Transmit Headsets are
typically used at the Driver, Officer and Pump Panel positions.
There are 2 models of Radio Transmit Headsets available for use with the 3000C Intercom
System: the UH-10 and the FH-10. There is a RED Push-To-Talk (PTT) button located on
the ear dome which allows communication on the radio
INTERCOM-ONLY HEADSETS
The Intercom-Only Headsets receive both intercom and radio communications at all times,
but are NOT radio-transmit capable. Intercom-Only are typically used at the jumpseat
positions, due to the high ambient noise level at these locations (engine noise, etc.).
There are 4 models of Intercom-Only Headsets: the UH-20, the FH-20, the UH-40 and
the FH-40.
• The UH-20 and the FH-20 have a BLACK Push-To-Talk (PTT) button on the ear
dome. Press and hold this black PTT to speak on the intercom.
The UH-40 and the FH-40 have a YELLOW Push-To-Talk (PTT) on the ear dome.
•
Press and release the yellow PTT to turn the microphone on. Press and release the
yellow PTT again to turn the microphone off.
HEADSET ADJUSTMENT
The vertical fit of the headset is adjusted by the adjustable headband (FH models) or the
adjustable headstrap (UH models).
• Over-The-Head (FH) style headsets (Figure 19): These headsets have adjustable
headbands with slide mechanisms located at each side above the ear domes. If the
adjustment slides become loose, gently tighten the self-locking nuts on the slide
mechanisms.
• Under-The-Helmet (UH) style headsets (Figure 20): These headsets have an
adjustable headstrap for adjusting the height of the ear domes.
For maximum comfort, wear the headset as far back on the head as possible, while ensuring
that the ear domes still completely cover the ears. If discomfort is felt in the jawbone, you
are wearing the headset too far forward.
