SYSTEM OPERATION

click on picture for enlarged view

The FireVox 400 Series Emergency Two-way Communication System provides fire fighting personnel with a 2-way communication between remote areas and the main control center.

To select remote station mm the Master Intercom panel, lift up the master handset from the cradle, press the respective zone 'SELECT' button on the Handset Zone Selection Module, and the selected zone L~D will then flash. When the Remote Handset answers by lifting the handset from the cradle, the flashing LED will become steady and two-way communication is then established. To terminate both parties will have to place back their handset to the cradle.

When the 'PRIVACY' button at the Master Handset Panel is off, any remote handset can call the Master Handset by lifting the Remote Handset. This will initiate the flashing of the respective zone LEO at the Master Intercom Panel. To answer the call, just lift up the Master Handset. Meanwhile, should a second remote party call, it will automatically join in the conversation, likewise for the subsequent calls.

However, if a second remote station's handset is lifted, trying to establish a conversation while the Master Handset Module 'Privacy' button is being pressed, the access will be denied and the Remote Station will hear a busy tone. This situation of an incoming/waiting call is monitored at the Master Intercom Panel by having the handset's designated LED flashing. For this handset to be accessible to the conversation, the controller/operator at the Master Intercom Panel will just have to depress the flashing LED's corresponding ‘SELECT' push-button to permit access, and a conference will then be established.

For the optional voice recording function, the recorder will automatically start recording all the broadcasted messages and signals from the PA system on one channel, and the voice traffic over the intercom system on the other whenever a fire alarm signal is being initiated. All signal inputs, recording status and time-lapse can be monitored at the Master Intercom Panel
