reporting etc OPTIONAL)
System
works as follows:
The system
is preset at default 15 minute. Upon the 15 minute is up the timer 1 (T1) will
kick in and activate the relay to trigger the baby siren. If the monitoring personnel
do not reset the baby siren after say 10 minute (time is programmable), the
second built-in timer (T2) will cut in and activate the 2nd relays to trigger
the master horn siren. In the event the baby siren trigger and the monitoring
personnel reset it, the system will automatically reset back to 15 minutes and
re-count again. If after 10 minutes are up and the baby siren is not reset the
master horn siren will trigger, in this instance to reset the system just press
any reset button and the system will reset back to the original preset timing
again.
