External Speaker
External Speaker
The external audio speaker output extends the audio output of the Cortex Handsets
directly from the Cortex Hub. The external audio speaker output will broadcast VHF
(when a Cortex Handset is present) and system alarms. The external audio speaker
output is perfect for Cortex Cortex Hub installations without a Handset, or where
Cortex Handsets are powered down and you still wish to become alerted to alarm
events on board.
Setting Audio Speaker Volume
Audio Speaker volume can be set at the desired volume using a Cortex Handset or
the Cortex Onboard App.
The external speaker should be installed at least 1m (3ft) from any magnetic
compass, flux gate sensor and the Cortex Hub.
It is recommended to use a 10W rated audio speaker with a 4-ohm impedance.
