Relay contact
The relay can be wired by a user to ring a bell or to sound a car horn. If a voice call is
received, the bell or horn sounds for 2 minutes. If it is an emergency call, it toggles on
and off three times per second, continuing for 5 minutes.
The contact can be configured via internal links to do one of the following in the case
of an alarm:
• join pins 6 and 7 together (normal, not available when 600  balanced audio
output is used), or
• switch pin 6 to ground, or
• switch pin 6 to battery volts (A rail)
NOTE: The external alarm is not activated under certain values of the Alert
Tones entry in Settings > Calling.
