EMERGENCY BUTTON:

On radios that have the necessary equipment on the dispatch side, the large orange button on the top of the

radio is programmed as the emergency button. Some APX shoulder microphones also have a similar orange

button on them that functions the same way.

Pressing this button, a single time, for at least one second activates an

emergency alert that only you and your dispatcher are aware of. Pressing the

PTT after pressing the emergency button elevates the emergency alert to an

emergency call. This allows you to override other users of the system and

transmit on the talk-group selected. All other users then become aware you

have activated an emergency call as their radios will send off tones and their

radio display will change colors and show your radio ID number.

To cancel an emergency alert or call, press and hold the emergency button for

at least two seconds until you hear a solid tone. It may take a few seconds for

the system to clear the emergency status. Shelburne Control will have to reset

the alarm if an Emergency Call was activated. This also applies to radios using

the Greenfield, Montague/Turners Falls and Orange talk-groups.

If activated unintentionally, do not cycle through the various talk-groups as

this will set off an emergency status on all the talk-groups you turn to. Always

contact Shelburne Control to advise of an accidental activation.

Refer to FCECS/CoMIRS Training Bulletin 2021-01 for a more detailed

explanation of how the emergency button functions on different talk-groups.
