Personal Communications Kit
Firemen can work with both hands while using walkie-talkies with a microphone-speaker kit announced by Setcom Corporation.
The kit, which weighs 3 ½ ounces, slips into a helmet. The speaker is within ⅛ inch of the fireman’s ear and a bone conductance microphone rests on his head. According to the manufacturer, wearing a mask does not interfere with communications. A pushto-talk switch is on a cord that can be run down a sleeve and clipped to a cuff of a turnout coat.
The kit can be used with any portable radio that has a remote microphone connector. The walkie-talkie can be worn under a turnout coat or in a coat pocket.

A two-part color slide kit on ventilation has been produced by Film Communicators. Part I of the kit contains 33 slides with a 12-minute tape cassette explaining the reasons for ventilation. Part II has 48 slides with a 16-minute tape on performing ventilation on the fireground.
Each kit also includes a study manual with a numbered illustration keying the text to each slide and the text is the same as that used by the narrator on the tape. The tape, which can be played in any standard cassette recorder, has a tone to indicate a slide change so that the slide presentation can be made with either a manual or automatic slide changer. The box containing the kit is made to be used for holding round or rectangular trays if the instructor wishes to store the slides in trays.

Public Systems inc. has developed the Mobile Radio Extension system to provide fire personnel with total integrated communications as an aid to improving fire fighting command and control procedures.
Firemen and command personnel are equipped with small Safety-Comm personal portable units which allow them to communicate with each other in ranges up to a quarter mile. These same units can be used as remote controllers for the standard mobile radio in emergency vehicles. The fireman thus is able to carry on two-way communications with his dispatcher and other mobile units.
The PSi Mobile Radio Extension system (Model MRE-721) works in conjunction with fire department radios in the 30-50 MHz and 450-512 MHz bands. The remote control function is accomplished by the installation of a special PSi control unit adjacent to the radio.
