Securitex Dead Man Alarm System (DMAS Ver.2SER)

In today security threads around the world, Vessel, Ships, Ocean liners and Super tankers are target that pirates and terrorist are looking to strike. At Securitex we have designed a system that allows the Onboard Security Personnel in the ship to do regular inspection and check round the clock without fail using Securitex DMAS. What is Securitex DMAS. DMAS is a programmable countdown timer system that is preprogrammed at a certain time interval. This timer will countdown and upon time –up the Siren connected to the DMAS will sound reminding the Security personnel to go for their rounds. (The more complex system can be interface to system than can activate distress signal and event 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) to be provided by others. If the monitoring personnel do not reset the baby siren after say 10 minute, the second built-in timer (T2) will cut in and activate the 2nd relays to trigger the (master horn siren) (also provided by others) In the event the baby siren trigger and the monitoring personnel reset it, the system will automatically reset to 15 minute and re-count again. If after 10 minute is 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.
