Voice Amplification System - Honeywell Titan SCBA Training Manual

The Voice Amplification System is designed to facilitate verbal communication while wearing
a facepiece. The unit provides the wearer a choice of brief or constant voice amplification by
pushing the power button on the top of the VAS.
One depression of the power button activates the VAS for two seconds.
Two consecutive pushes of the power button activates the VAS of continuous use.
Two more consecutive pushes of the power button will turn the VAS off.
A red LED light is visible to the user on the right side of the facepiece to indicate the unit is on.
An amber LED light will blink to warn the user of a low battery. The VAS is powered by three
AAA batteries and can be changed in the field by opening the battery compartment door at the
front of the housing. The VAS attaches to the right side of the facepiece using an alignment tab
and a threaded knurled knob. Electrical contacts connect the VAS to the microphone located
within the facepiece. The amplifier's low attachment location minimizes obstruction of the
wearer's vision, and the ergonomic controls allow operation with a gloved hand.
