[LW-MCU] will at a preset time trigger an alarm that requires the personnel
[working crew] on duty to reset the alarm thus indicated that he or she is
well, if this activated alarm is not acknowledge after a preset time say
10-15 minute, the second alarm will be set off at the monitoring office

c. 1 unit secondary motor horn siren OUTPUT 12VDC
d. 2 units remote location reset switch INPUT DRY CONTACT
e. 1 unit 3G SMS Controller c/w input and output control module.
By default the system is preset at 15 minute for the first alarm, if
at anytime the reset button is push. The system will reset to 15 minute
again. However if the first alarm is not acknowledge the LW-MCU will give

go on for another 10 minute and than the secondary siren will activate (All
this timing duration can be preset and reprogrammed at site). To deactivate
the siren the Monitoring officer have to press the reset switch on the
