Alarm delay s

When set to 1, the audible sounder are reset (and the relays if 
defined: Relay rest enable) to no alarm indication. When the alarm is 
reset or the time out duration is exceeded, the value is reset to 0.
Note: The alarm condition is not reset only the output indication is 
reset. 
0: Alarm outputs not reset 
1: Alarm outputs reset –buzzer muted and relays reset if configured
