Priority Interrupt 2

Priority Interrupt : Responding to serious incidents

If a Chatterbox Alarm Location Monitoring (CALM) system offers ‘Priority Interrupt’ it means that, in the event of a fire or other threat to personnel or public safety, key radio operators (e.g. security managers) can push the ‘Priority Interrupt’ emergency button on their radio, enabling them to interrupt any incoming or outgoing call on the radio system. This is potentially useful in a scenario where one of the radio users is making the current radio channel busy and a manager or security officer needs to relay critical information. Priority Interrupt pulls all the two-way radios in the system on to an emergency channel. Radio users can, if they need to, respond immediately to all other users making evacuations and the response to critical situations quicker as there is no need for any users to change radio channels. Pressing the button initiates Priority Interrupt, and when the same button is pressed again the system reverts to normal i.e. the channels separate.
