External, audible alarm
In addition to the alarm output contact described in the previous section, you can connect either a
speaker or an intercom system to the Stratomaster Ultra. In this case an alarm tone will sound
once a second for half a second whenever an alarm is active.
In case you connect a speaker, you should set the audio level to “high” by bridging the relevant
link position. Should you want to connect to an intercom system that has an external audio input,
set the audio level to “low”.
Note: Please ensure that your intercom system will mute any external audio should radio
transmissions be received. It may be illegal in your country to use any other system.
