Connecting to an Emergency Switch and/or
External Alert Devices
The auxiliary connector can be used to connect external devices and signals
that are typically connected to a radio. These devices and signals include:
■
an emergency switch to power up the radio (if required) and then enter
emergency mode
■
external alert devices
■
other external devices or signals.
Table 3.2
gives an overview of the connector pins and their possible uses.
Emergency Switch
The radio allows for connection of an emergency switch to any input line
to enter the emergency mode. If the switch is connected to the AUX GPI2
input line, the radio can also use ‘emergency power sense’ to power up the
radio to enter the emergency mode.
The selected input line must be programmed to ‘Enter Emergency
Mode’ and active to ‘Low’. To use ‘emergency power sense’, hardware
link LK3 must be fitted (factory default), and AUX GPI2 must be used.
For more information, refer to the service manual and the online help of
the programming application.
Connect a normally open switch between the pin of the input line
(pin 5 for AUX GPI2) and pin 15 (AGND) of the
auxiliary connector.
