9.3 ALARM RELAY OPTIONS

selections made in the COMMISSIONING menu functions #45 to #48.
The relay contacts are all designed to be “Fail Safe”. That is, they are
 open when the transmitter power is off
 closed when there is NOT an alarm condition

The contact will close circuit again (relay energised) when the alarm condition is acknowledged.
